The primary rules that apply to the mailing of hazardous materials, restricted matter, and perishable matter and that take precedent over all other postal information are found in DMM C020-C024. 112 Use This publication is designed for use by postal personnel in business mail entry, retail units, marketing, and other functional areas that are involved with providing mailability information to postal customers. The mailing rules in the DMM along with the additional guidelines contained in this publication are to be followed when deciding whether and under which conditions hazardous materials, restricted matter, and perishable matter are permitted to be mailed. Because the content of this publication is based on DMM standards and the regulations of federal agencies current at the time of publication, future changes to the DMM and federal regulations may supplement, amend, or supersede the content of this publication. 113 Other Reference Sources No single postal guide could provide all the details necessary for the safe acceptance and handling of every item that is classified as hazardous material, restricted matter, or perishable matter. This publication attempts to provide general guidelines, along with specific mailability requirements, where possible for those categories of harmful materials that either present significant danger or are frequently presented for mailing. In writing this publication, the following sources were used: * Title 18 United States Code 1716 (18 U.S.C. 1716). * Title 39 United States Code 3001 (39 U.S.C. 3001). * Domestic Mail Manual (DMM) C020-C024. * International Mail Manual (IMM) 135-139. * Title 49 Code of Federal Regulations (49 CFR). * Postal Operations Manual (POM). * Administrative Support Manual (ASM). Where appropriate within the text of this publication, the names and addresses of agencies from which more detailed information can be obtained are provided. A complete listing of postal and nonpostal publication references is located in Appendix F. 12 Scope 121 General The scope of this publication extends to all articles and materials that are nonmailable because they may harm persons or property coming into contact with them, or that have had mailing restrictions imposed upon them as a matter of public policy or by the regulations of other governmental agencies (see DMM C021). Under 18 U.S.C. 1716, all matter that is outwardly or of its own force dangerous or injurious to life, health, or property is nonmailable. The knowing deposit of such matter in the mail is a crime punishable by fine, imprisonment, and/or other penalty. However, certain hazardous materials and otherwise restricted and perishable matter may be mailed under the conditions permitted in DMM C020-C024 and this publication. 122 Hazardous, Restricted, and Perishable The following are examples of hazardous materials, restricted matter, and perishable matter. These are not complete lists, but they provide an idea of the types of articles included in each category. a. Hazardous materials (DMM C023) include: (1) Corrosives. (2) Explosives. (3) Flammable liquids and solids, combustible liquids. (4) Gases (under pressure). (5) Infectious substances, etiologic agents, clinical specimens, biological products, sharps, other used medical devices. (6) Miscellaneous hazardous materials (i.e., dry ice, magnetized materials). (7) ORM-D materials. (8) Oxidizers, organic peroxides. (9) Radioactive materials. (10) Toxic substances (poisons). b. Restricted matter (DMM C024) includes: (1) Abortive and contraceptive devices. (2) Battery-powered devices. (3) Building construction materials. (4) Controlled substances and drug paraphernalia. (5) Firearms. (6) Intoxicating liquors. (7) Liquids and powders. (8) Matter emitting obnoxious odors. (9) Motor vehicle master keys. (10) Nonhazardous liquids and powders. (11) Sharp objects (knives, switchblades, stilettos). (12) Odd-shaped items in letter-size envelopes. c. Perishable matter (DMM C022) includes: (1) Dead animals or parts of animals. (2) Eggs. (3) Live animals. (4) Meat and meat products. (5) Plants and plant products. 13 Additional Information Although the Postal Service makes every effort to inform its customers of the mailability of particular harmful matter via the DMM standards and the information in this publication and others, it is the responsibility of the mailer to fully meet all requirements prior to mailing. See 212 and DMM C021 for more complete information on the responsibilities of mailers. The authority of postal personnel to decide whether particular articles and substances presented for mailing are nonmailable due to the restrictions in DMM C020-C024 and this publication, is stated in 213 and DMM C021. 14 Safety The handling and transport of hazardous materials, restricted matter, and perishable matter involves added levels of risk. That risk can become even greater if a nonmailable material is mailed or if the packaging of a mailable material is not adequate to prevent damage or spillage during normal handling. Under no circumstances may any nonmailable hazardous material, restricted matter, or perishable matter be deposited for mailing. Mailable items must be packaged and labeled as required in the applicable DMM rules and the guidelines in this publication. The Postal Service's primary purpose in requiring proper packaging, identification, and deposit of mailable hazardous materials, restricted matter, or perishable matter is to ensure the safety of our employees and the general public who may come into contact with these mailpieces. These requirements are also intended to ensure the safety of the mailstream, postal equipment, and postal facilities. 15 Protecting Personnel All reasonable and necessary steps must be taken to protect Postal Service personnel and equipment from the effects of potentially dangerous or injurious materials or substances found in the mail, as stated in Administrative Support Manual (ASM) 223.4. 2 General Guidelines 21 Mailability 211 General Under 18 U.S.C. 1716, all matter that is outwardly or of its own force dangerous or injurious to life, health, or property is nonmailable. The knowing deposit of such matter in the mail is a crime punishable by fine, imprisonment, and/or other penalty. However, some hazardous materials, and otherwise restricted matter or perishable matter, are permitted to be mailed when the primary requirements specified in DMM C020-C024 and the supplemental criteria in this publication are fully met. For reasons of safety, most hazardous materials are nonmailable. DMM C023, along with Chapter 3, Appendix A, and Appendix C of this publication, provide detailed information on which hazardous materials are permitted to be mailed and the conditions that apply. Restricted matter and perishable matter are either nonmailable or mailable only under the specific conditions stated in DMM C022 and C024, and Chapters 4 and 5 of this publication, as applicable. The mailing conditions that apply to hazardous materials, restricted matter, and perishable matter in international mail are specified in Chapter 6. Chapter 7 contains information on the specific conditions that apply to the air transportation of mailable hazardous materials, restricted matter, and perishable matter. 212 Mailer Responsibility The mailer is responsible for complying with all mailability statutes and regulations that apply to a specific material and needs to keep abreast of current regulations adopted by the Postal Service and other governmental agencies. See DMM C021 for a more complete statement of the responsibility of postal customers regarding the mailing of hazardous materials, restricted matter, and perishable matter. The Postal Service disseminates information about mailing rules by publishing the DMM and IMM, and by providing this publication and others that furnish additional guidance to mailers. 213 Authority A postmaster is granted the authority under DMM C021 to determine the mailability of restricted articles and substances. A postmaster who has determined an article or substance to be nonmailable is authorized to refuse the item from mailing. Postmasters may consult with a rates and classification service center (RCSC) in making these determinations. See DMM G042 for the RCSC addresses and telephone numbers. 214 Appeals The rights of mailers to seek review of adverse mailability decisions involving restricted articles and substances is stated in DMM C021. A mailer receiving an adverse decision from a postmaster may file a written appeal with the RCSC, which issues the final postal agency decision. When the initial ruling is issued by the RCSC, a mailer may appeal to the Manager, Business Mail Acceptance, USPS Headquarters, Washington, DC. See DMM G043 for mailing address. A mailer may file a written appeal of the final postal agency decision with the USPS Recorder, Judicial Officer, under the rules of procedure in 39 CFR 953. See DMM G043 for mailing address. 215 Requests for Rulings 215.1 General Mailability decisions are based on Postal Service statutes and regulations current at the time the ruling is issued. Therefore, over time some rulings may become obsolete or require modification to conform to changes in applicable laws and regulations. When rulings are issued, the requirements of other governmental agencies (i.e., U.S. Department of Transportation, Centers for Disease Control and Prevention) are often taken into consideration to the extent that they are consistent with Postal Service policy and authority. Requests for rulings must contain specific items of critical information appropriate to the category of the item, as noted in 215.2 and 215.3. 215.2 Hazardous Materials To obtain a ruling on the mailability of a specific hazardous material prior to mailing, a mailer must furnish the information required in DMM C023.1.5, and a material safety data sheet (MSDS), to the RCSC serving their location. (See Appendix D for a definition of MSDS.) Because the misspelling of even one letter of the proper shipping name for a hazardous material could change the classification requirements, the following information must be furnished when requesting a mailability ruling for a hazardous material: a. Common and proper shipping name of the material, hazard class, and the assigned United Nations (UN) or North American (NA) identification number. b. Chemical composition by percentage of weight. c. Flashpoint. d. Toxic properties. e. Irritant action when inhaled, swallowed, or brought in contact with skin or eyes. f. Special precautions necessary to permit handling without harm to USPS employees or damage to property or other mail. g. Explanation of warning labels and shipping papers required by local, state, or federal regulations. h. Proposed packaging method, including the addressing, required markings, and documentation. i. Volume of material per mailpiece, proposed number of pieces to be mailed, class of mail, and post office(s) of mailing. Be aware that the hazard present with chemicals and other types of hazardous materials is often not necessarily apparent. Materials classified under one hazard class can present additional or subsidiary hazards more commonly associated with a different hazard class. For example, swimming pool chemicals may cause fires or release poisonous fumes, or they may be corrosive or poisonous. Other chemicals may be cancer-causing agents and must be packaged according to the requirements for toxic substances. Therefore, it is essential when determining mailability to correctly identify the material based on the mailer-supplied documentation (i.e., MSDS and other information) and never to assume a general designation using unsubstantiated information. 215.3 Restricted Matter or Perishable Matter To obtain a ruling on the mailability of restricted matter or perishable matter, a mailer should provide specific information to the local postmaster. This information should include the following: a. Detailed description of the restricted matter or perishable matter. b. Special precautions necessary to permit handling without harm to postal employees or damage to property. c. Proposed method of packaging. d. Explanation of any local, state, or federal regulations that apply to shipping such matter. e. Quantity per mailpiece and per mailing, frequency of mailing, and post office(s) of mailing. When information for restricted or perishable matter is insufficient to make a mailability determination, or when there is doubt about the mailability of a particular article, assistance can be requested from the appropriate RCSC. 216 Nonmailable Matter Found in the Mail Certain firearms, switchblade knives, controlled substances, motor vehicle master keys, and explosive or incendiary devices are not permitted to be mailed under DMM C020-C024. When these types of nonmailable items are found in the mailstream, they must be handled in accordance with POM 139.117. Other types of materials found in the mail that are believed to be nonmailable must be treated within the applicable conditions in DMM C010.10, POM 139.117-118, and ASM 223.4. 22 Marking Requirements 221 General Hazardous materials and restricted or perishable matter, unless specifically excepted in 222, must be clearly identified on the address side of the mailpiece. The following requirements must be met: a. The identity of the contents must appear, when required, on the address side. b. The name and address of both the mailer and addressee must appear on the address side. Other markings required by the Postal Service or other federal regulatory agencies must be affixed to the address side of any mailpiece containing hazardous material, restricted matter, or perishable matter. Required markings must be applied with a nonsoluble material or other material that cannot be rubbed off or smeared. As stated, the contents must be disclosed to be mailable. Subsequently, the need for a mailability determination may result from a disclosure provided by a mailer at the time of mailing. Advise mailers of all applicable labeling and marking requirements to avoid rejection of the mailpiece by postal acceptance personnel or air carriers. 222 Matter Excepted From Markings If permitted to be mailed under DMM C024, the following materials are excepted from the requirements in 221 and must be mailed with no indication or identifying marking on the outside of the parcel: a. Controlled substances and drugs. b. Firearms. c. Motor vehicle master keys. d. Switchblade knives. 223 Hazardous Materials Warning Labels and Markings Most mailable hazardous materials fall within the ORM-D (other regulated materials) category. ORM-D materials do not require Department of Transportation (DOT) diamond-shaped hazardous materials warning labels. However, postal regulations do permit the mailing of a few hazardous materials that fall outside the ORM-D materials category. See Chapter 3, Exhibits 325a and 325b, and DMM C023 for more specific information on hazardous materials warning labels and marking requirements. 224 Tag 44 for Hazardous Materials Any sack or other consolidation device containing a hazardous material must have a PS Tag 44, Sack Contents Warning, attached. The tag must be removed when the hazardous material is no longer in the sack or consolidation device. See Chapter 7 for more information. 225 Other Postal Labels and Tags The Postal Service provides the following labels and tags that may be affixed to the outside of mailpieces containing live animals, bees, or perishable matter, in addition to any required markings: a. Label 27, Bee Ware! b. Label 28, Live Animals. c. Tag 9, Perishable --Do Not Delay. 226 Package Orientation Markings Outer packagings that contain a primary receptacle (and secondary packaging, if required) of a liquid or other spillable material must be packed with the closure of the primary receptacle positioned upward. The outer packaging must be plainly and legibly marked on two opposite side walls with a package orientation marking, which consists of two underlined arrows that point in the correct upright position. As an option, the two arrows may be enclosed within a rectangle. The specifications for a package orientation marking are in 49 CFR 172.312. See Exhibit 226 for examples. Exhibit 226 Package Orientation Markings Picture not available Note: Either design is acceptable. 227 Old Markings Old or nonapplicable markings remaining on reused boxes or containers must be entirely removed or completely obliterated prior to mailing. Under 49 CFR 173.29, a container that previously held a hazardous material is considered the same as a full container of the hazardous material. For example, a container that previously held a flammable liquid, corrosive, flammable gas, toxic material, infectious substance, etc., must be considered and treated as if it still contained the hazardous material. For this reason, these types of containers must never be reused to mail other items. 228 Shipping Papers Mailable hazardous materials eligible to be sent as Express Mail, Priority Mail, or First-Class Mail must be packaged, labeled, and appropriately documented for air transportation, as required by federal regulations and DMM C023. Mailable hazardous materials sent via air transportation (except clinical specimens and biological products eligible under 346.2 and DMM C023.8.4) must be accompanied with a shipper's declaration for dangerous goods that is completed in triplicate and signed by the mailer. See 326 and Exhibit 326 for more information. Advise mailers they must comply with this requirement in order to avoid air carrier rejection of a mailpiece based on failure to provide shipping papers. Also see Chapter 7 for more information on air transportation requirements and air carrier refusals of mailable items. 23 Handling Hazardous Materials A potentially dangerous situation always exists when hazardous materials, restricted matter, or perishable matter is being moved from one place to another. Careless handling can result in serious injury to the general public and postal personnel, damage to other mail and postal equipment, and delays in processing and delivery of mail. Specific guidelines on how to properly handle these materials during postal handling are contained in Memorandum of Policy OS-04-21-98, Hazardous Materials and Dangerous Goods in the Mail, and the POM. 24 Emergency Procedures 241 General Requirements Incidents involving the release of hazardous materials, restricted matter, or perishable matter are potentially serious and can cause death, injury, and property damage. Incidents can be avoided or minimized if appropriate preventive measures are taken or correct emergency procedures followed. The guidelines for responding to emergency situations are found in Management Instruction (MI) EL-810-96-1, Response to Hazardous Materials Releases, and Handbook EL-812, Hazardous Materials and Spill Response. These guidelines must be followed by all postal employees involved in the flow of mailpieces containing harmful matter, from the point of deposit to the point of delivery. 242 Hazard Duration In general, remember that exposure to the effects from damage, spillage, or leakage of harmful matter frequently is not obvious or readily apparent. For example, infectious substances, radioactive material, corrosives, and poisons can cause illnesses or injuries that become known to the victim gradually and only long after the incident. 243 Precautions During any spill or leak incident, or when damage is detected involving harmful items, postal personnel must take every precaution to protect personnel and property from visible and invisible effects of the material involved. These procedures are to be followed: a. Identify harmful properties of the material and precautions to be taken. b. Provide adequate personal protection to employees who must handle materials. c. Contain and transport leaking containers for disposal. d. Clean and decontaminate facilities and machinery. e. Refer to MI EL-810-96-1, Response to Hazardous Materials Releases, and Handbook EL-812, Hazardous Materials and Spill Response, for specific instructions. 244 Procedures During any incident involving harmful matter where there is actual or suspected damage to a mailpiece or its contents, the following general guidelines apply. The specific procedures to be used by postal personnel are in Handbook EL-812, Hazardous Materials and Spill Response: a. Isolate the damaged package immediately and restrict the area. If the incident occurs in a facility or on the equipment of an air carrier, immediately brief the carrier on the nature and quantity of the materials released. b. Contact the supervisor or designated qualified employee, who can take prompt and appropriate measures to protect life and prevent injury, loss, or damage. If mail sealed against inspection must be opened for this purpose, act in accordance with ASM 274. c. Remove any injured or contaminated person from the area with as little physical contact as possible: (1) Limit any first aid to what is absolutely necessary until a qualified physician is present. (2) Direct all personnel exposed to radioactive materials to wash all exposed body areas immediately with cold water and immediately report to a physician for an examination. d. Contact the fire department, the police, a qualified physician, and/or the appropriate agencies equipped to handle specific situations. e. Keep out of smoke, fumes, or dust. Segregate any clothing or tools used in fighting fires until they can be checked for contamination. f. Do not eat, smoke, or drink in the affected area. g. Do not place involved areas in service until the proper authorities have determined that the areas are free of all contamination. h. Notify the nearest RCSC or postal inspector, as appropriate in POM 139.117-118 (see 216). A report must be made for any incident that includes damage to mail or property, or injury to personnel. PS Form 1770, Hazardous Materials Incident Report, must be completed and forwarded in accordance with instructions on the form. i. Comply with reporting procedures outlined in Memorandum of Policy OS-04-21-98, Hazardous Materials and Dangerous Goods in the Mail, for reporting hazardous materials incidents that occur while materials are being transported as mail aboard an aircraft. 245 Hazardous Chemical Emergencies CHEMTREC (Chemical Transportation Emergency Center) is a service of the Chemical Manufacturers Association that provides immediate information and advice 24 hours a day, 7 days a week, for those at the scene of transportation emergencies involving chemicals. CHEMTREC also follows up by promptly contacting the shipper of the chemicals involved for more detailed assistance. Postal Service personnel are authorized to telephone CHEMTREC day or night, toll-free, at 800-424-9300. For calls originating within the state of Virginia or outside the continental United States, telephone 703-527-3887. CHEMTREC usually can provide hazard guidance and information warnings when given only the name of the product and the nature of the problem, but they do not provide on-site emergency response. Before contacting CHEMTREC for assistance, obtain as much of the following information as possible: a. Consignee (sender). b. Container type. c. Local conditions. d. Location of problem. e. Your full name and a call-back telephone number where you can be reached. f. Shipper or manufacturer of the material. 246 Other Emergencies The following is a reference list of telephone hotline numbers (for use during normal business hours unless otherwise noted) related to other types of emergencies: U.S. DEPARTMENT OF TRANSPORTATION (DOT) NATIONAL RESPONSE CENTER (For Chemical and Oil Spills) 202-267-2675 (within Washington DC) 800-424-8802 (outside Washington DC) CENTERS FOR DISEASE CONTROL AND PREVENTION (CDC) (For Etiologic Agents and Biohazard Materials) 404-639-3883 (Day) 404-633-5313 (Night) AMERICAN CROP PROTECTION ASSOCIATION 202-296-1585 25 Basic Guidelines for Acceptance and Dispatch 251 Guidelines for Acceptance Personnel Postal personnel may not open mail sealed against inspection except under the circumstances described in ASM 274. Accordingly, knowledge of the content of such mail may be obtained directly from the mailer (i.e., a mailer may ask questions about mailing requirements or mark the outside of the mailpiece to indicate the contents) or indirectly through leakage or other escape of the contents. Subject to the applicable restrictions, acceptance personnel must: a. Determine the mailability of all hazardous materials, perishable matter, or otherwise restricted matter offered for mailing at a retail unit or business mail entry unit (BMEU). b. If the contents are mailable, determine the specific quantity limitations, labeling, and packaging requirements that apply. c. Refuse to accept any material (as permitted in POM 139) that does not meet the applicable DMM requirements for mailing (see DMM C021) and refer the circumstances to your local postmaster or RCSC for a mailability ruling under 213 or 215, as appropriate. d. If the parcel containing the hazardous material is in a pouch or sack, PS Tag 44 must be attached to ensure the sack will be emptied at the processing point. Dispatch all mailable hazardous materials as stated in Memorandum of Policy OS-04-21-98, Hazardous Materials and Dangerous Goods in the Mail, and the POM. See Chapter 7 for the acceptance personnel guidelines when handling hazardous materials, restricted matter, or perishable matter to be transported by air. 252 Guidelines for Dispatch Personnel The following guidelines for postal dispatch personnel are general in nature. Specific dispatch procedures for postal operational employees are in Memorandum of Policy OS-04-21-98, Hazardous Materials and Dangerous Goods in the Mail, and the POM. a. Make sure that the hazardous material, restricted matter, or perishable matter is given proper handling to avoid damage or danger. b. Tender to the air carrier only those mailpieces that are properly packaged and marked. Before a shipment is tendered to a carrier, make sure that: (1) A proper and strong packaging method is used. (2) A secure method of package closure is used, and there is no visual evidence of leakage or damage. (If damage is detected, isolate the damaged mailpiece and notify the appropriate personnel in case of accident or incident and for proper spill response.) (3) The outer packaging bears all required markings and/or labels. (4) A properly completed shipping paper is attached to the outside of the mailpiece and to the dispatch document. The shipping paper must include the information detailed in 326 and Exhibit 326. (5) If the mailpiece contains a material believed to be nonmailable, treat it in accordance with POM 139.117-118, as appropriate. See Chapter 7 for more information regarding the air transportation of mailable hazardous materials, restricted matter, or perishable matter. 3 Hazardous Materials 31 Definition A hazardous material is any article or substance designated by the U.S. Department of Transportation (DOT) as being capable of posing an unreasonable risk to health, safety, or property during transportation. In international commerce, hazardous materials are known as "dangerous goods." For definitions of other terms that relate to hazardous materials, refer to Appendix D. 32 General 321 U.S. Department of Transportation (DOT) The U.S. Department of Transportation (DOT) is the federal agency responsible for regulating the carriage of hazardous materials within the United States via any mode of transportation (i.e., highway, rail, air, water). The federal regulations of DOT are codified in Title 49 Code of Federal Regulations (49 CFR). 49 CFR contains DOT's detailed specifications for packaging, marking, and labeling hazardous materials. Title 49 also exempts or establishes other requirements for limited quantities and small quantities of hazardous materials. 322 Postal Service The carriage of U.S. Mail by the Postal Service is regulated by Title 39 Code of Federal Regulations (39 CFR) and is not subject to the federal regulations in 49 CFR as commercial carriers are. Unlike the commercial carriers, the Postal Service is, however, subject to the restrictions in Title 18 United States Code 1716 (18 U.S.C. 1716), which prohibits from mailing all matter that is outwardly or of its own force dangerous to life, health, or property (see 211). Accordingly, for legal and safety reasons, the postal mailing standards for hazardous materials in DMM C023 and this publication not only closely adhere to 49 CFR, but also include many additional limitations and prohibitions. In many instances, the postal standards are more restrictive than the requirements of other commercial carriers. For example, 49 CFR allows commercial shippers to send flammable materials by air, but the Postal Service prohibits the mailing of all flammable materials via air transportation. As a result, most hazardous materials are nonmailable. The postal regulations generally limit the mailing of hazardous materials to ORM-D materials as defined in 333. Although most mailable hazardous materials fall within the ORM-D category, postal regulations do permit the mailing of a small number of hazardous materials having a greater handling and transportation risk than ORM-D materials. This allowance is limited to the following: a. Toy propellant devices and safety fuses in Division 1.4S as permitted in 341.22 and DMM C023.2.0. b. Toxic substances in Division 6.1 that have an LD50 for oral toxicity of greater than 5 mg/kg but less than 50 mg/kg as permitted in 346.231 and DMM C023.7.0. c. Infectious substances (etiologic agents) and medical wastes in Division 6.2 as permitted in 346.23 and DMM C023.8.0. d. Radioactive materials in Class 7 that fall within the specific activity limits permitted in 347 and Exhibit 347.22. e. Dry ice and magnetized materials in Class 9 as permitted in 349 and DMM C023.11.0. 323 Mailer Responsibility Full responsibility rests with the mailer to comply with all postal and nonpostal laws and regulations in the mailing of hazardous material. Anyone who mails, or causes to be mailed, a nonmailable or improperly packaged hazardous material can be subject to legal penalties (i.e., fines and/or imprisonment), including but not limited to those specified in 18 U.S.C. The transport of hazardous materials prior to entry as U.S. Mail is subject to DOT regulations. 324 Mailability Rulings For information on how to request a mailability ruling for a specific hazardous material, see 215.2 and DMM C023.1.5. 325 DOT Hazardous Materials Warning Labels In commerce, packages containing hazardous materials (except those qualifying as an ORM-D material or a limited quantity shipment) must display the appropriate DOT diamond-shaped hazardous materials warning label. Any mailpiece bearing, or required under 49 CFR to bear, one of the warning labels shown in Exhibit 325a is prohibited from mailing. The warning labels shown in Exhibit 325b may appear only on mailpieces containing mailable hazardous materials that require use of the label under postal requirements. (The labels shown in the exhibits are not shown to size. DOT warning labels must meet the size and color requirements in 49 CFR 172.407 to 172.446.) Exhibit 325a DOT Hazardous Materials Warning Labels: PROHIBITED IN THE MAIL Pictures of labels not available Exhibit 325b DOT Hazardous Materials Warning Labels: PERMITTED ON MAILABLE HAZARDOUS MATERIALS Picture of labels not available. 326 Shipping Papers A shipping paper is defined as a shipping order, bill of lading, waybill, manifest, or any other document used to identify a hazardous material being offered for transport. The requirements on how to properly prepare shipping papers are detailed in 49 CFR 172.200 through 172.204. The shipping paper must be affixed to the outside of the mailpiece. A plastic envelope or carrier can be used for this purpose. The following conditions also apply: a. Air Transportation. Most mailable hazardous materials (including ORM-D materials) must be accompanied by a shipper's declaration for dangerous goods (i.e., shipping paper). The document must be properly completed and signed in triplicate by the mailer. A sample form is shown in Exhibit 326. To determine which mailable hazardous materials require a shipping paper when sent via air transportation, refer to the appropriate sections in this chapter, the appropriate Packaging Instruction in Appendix C, and DMM C023. b. Surface Transportation. A mailpiece containing a mailable hazardous material other than an ORM-D material must be accompanied by a properly prepared shipping paper. Neither DOT nor the Postal Service makes blank shipper's declaration forms available to shippers of hazardous materials. It is the responsibility of the shipper to obtain forms meeting the format specifications in 49 CFR from commercial printers or vendors. The shipper is also responsible for properly completing the form prior to mailing. 327 Transportation Requirements 327.1 General a. Air Transportation. Mailable hazardous materials eligible for air transportation must be sent as Express Mail, Priority Mail, or First-Class Mail, as permitted. Mailpieces must be prepared to meet all requirements that apply to air transportation, regardless of whether the parcel will be transported by air by the Postal Service. Mailpieces must be properly packaged and labeled within DMM requirements and the operator variations of the air carrier. When required, a shipper's declaration for dangerous goods must be affixed to the outside of the mailpiece. Refer to the Technical Instructions for the Safe Transport of Dangerous Goods by Air of the International Civil Aviation Organization (ICAO) for air carrier operator variations. Note: Mailable hazardous materials that are prohibited from air transportation may not be sent at the Express Mail, Priority Mail, or First-Class Mail rates. b. Surface Transportation. All mailable hazardous materials eligible to be sent at the Standard Mail rates must be prepared under the requirements that apply to surface transportation. A mailpiece containing a mailable hazardous material with postage paid aStandard Mail rate must not, under any circumstance, be transported on air transportation. Exhibit 326 Shipper's Declaration for Dangerous Goods (Sample Form) Picture of form not available 327.2 Air Transportation Prohibitions The following types of hazardous materials are prohibited from transport via aircraft (i.e., Express Mail, Priority Mail, or First-Class Mail rates) under any circumstances: a. Anything susceptible to damage or that can become harmful because of changes in temperature or atmospheric pressures unless protected against the effects of such changes. b. Magnetic material that has a field strength sufficient to cause a compass deviation at a distance of 7 feet or more from any point on the outer packaging. c. Flammable materials (gases, liquids, and solids). d. Radioactive materials. e. Hazardous materials excluded from air shipment by the regulations of 49 CFR 100-185, or by the applicable country or air carrier operator variations. 328 Postal Hazardous Materials Table Appendix A, "Hazardous Materials Table: Postal Service Mailability Guide," contains a modified version of the DOT Hazardous Materials Table found in 49 CFR 172.101. Appendix A lists the hazardous materials from 49 CFR and identifies eligibility for mailing in the domestic mail via air and surface transportation. The table can be used to determine the mailability of a hazardous material if the proper shipping name of the material is known. When only the UN number is known, Appendix B, "Numerical Listing of Proper Shipping Names by Identification (ID) Number," can be used to locate a proper shipping name for cross referencing back to Appendix A. The mailability information in Appendix A is based on DMM C023, the guidelines in this publication, and past postal mailability rulings. The table does not include specific information for international mail because almost all hazardous materials are prohibited in international mail. See Chapter 6 for the specific requirements that apply to international mail. 33 Hazard Classes 331 Nine Classes Every hazardous material is assigned to one of nine hazard classes as defined in 49 CFR 172.101 and 173. The nine hazard classes are as follows: a. Class 1: Explosives. b. Class 2: Gases. c. Class 3: Flammable and Combustible Liquids. d. Class 4: Flammable Solids. e. Class 5: Oxidizing Substances, Organic Peroxides. f. Class 6: Toxic Substances and Infectious Substances. g. Class 7: Radioactive Materials. h. Class 8: Corrosives. i. Class 9: Miscellaneous Hazardous Materials. Some of the nine classes are further separated into divisions based on their physical or chemical properties, as shown in Exhibit 331. Exhibit 331 (p. 1) DOT Hazard Classes and Postal Mailability Domestic Mail Class Name of Hazard Class (and Division when applicable) Air Transportation Surface Transportation International Mail 1 Explosives Division 1.1: Mass Explosive Hazard Prohibited Prohibited Prohibited Division 1.2: Projection Hazard Prohibited Prohibited Prohibited Division 1.3: Fire and/or Minor Blast/Minor Projection Hazard Prohibited Prohibited Prohibited Division 1.4: Minor Explosion Hazard Prohibited Only with prior HQ approval per 341 Prohibited Division 1.5: Very Insensitive With Mass Explosion Hazard Prohibited Prohibited Prohibited Division 1.6: Extremely Insensitive; No Mass Explosion Hazard Prohibited Prohibited Prohibited 2 Gases Division 2.1: Flammable Gases Prohibited Only ORM-D material per 342 Prohibited Division 2.2: Nonflammable Gases Only ORM-D material per 342 Only ORM-D material per 342 Prohibited Division 2.3: Toxic Gases Prohibited Prohibited Prohibited 3 Flammable and Combustible Liquids All Flammable Liquids Prohibited Only ORM-D material per 343 Prohibited All Combustible Liquids Only ORM-D material per 343 Only ORM-D material per 343 Prohibited 4 Flammable Solids Division 4.1: Flammable Solids Prohibited Only ORM-D material per 344 Prohibited Division 4.2: Spontaneously Combustible Prohibited Only ORM-D material per 344 Prohibited Division 4.3: Dangerous When Wet Prohibited Only ORM-D material per 344 Prohibited 5 Oxidizing Substances, Organic Peroxides Division 5.1: Oxidizing Substances Only ORM-D material per 345 Only ORM-D material per 345 Prohibited Division 5.2: Organic Peroxides Only ORM-D material per 345 Only ORM-D material per 345 Prohibited Exhibit 331 (p. 2) DOT Hazard Classes and Postal Mailability Domestic Mail Class Name of Hazard Class (and Division when applicable) Air Transportation Surface Transportation International Mail 6 Toxic Substances and Infectious Substances Division 6.1: Toxic Substances ORM-D material per 346; other poisons as permitted in 346.231 ORM-D material per 346; other poisons as permitted in 346.231 Prohibited Division 6.2: Infectious Substances Only as permitted in 346 Only as permitted in 346 Only registered air letters per 622 7 Radioactive Material Prohibited Only per 347 Only registered air letters per 622 8 Corrosives (Liquids And Solids) Only ORM-D material per 348 Only ORM-D material per 348 Prohibited 9 Miscellaneous Hazardous Materials ORM-D material and other materials as permitted in 349 ORM-D material and other materials as permitted in 349 Prohibited, except for magnetized materials per 349 and 622.4 332 Limited Quantity A limited quantity of a hazardous material is the maximum amount of a specific hazardous material exempted from the DOT labeling or packaging requirements in 49 CFR. To be eligible to be shipped under DOT's limited quantity provision, a hazardous material must be authorized an exemption in column 8A of the Hazardous Materials Table in 49 CFR 172.101. Not every hazardous material is eligible to be shipped as a limited quantity. Under postal mailing rules, a material meeting the eligibility criteria for shipment as a limited quantity is mailable only if it can be further reclassed as an ORM-D material (see 333). Not every hazardous material permitted to be shipped as a limited quantity can qualify as an ORM-D material. Those that cannot are not eligible for mailing, except as specifically permitted in DMM C023 and this publication. 333 ORM-D Materials Some of the hazardous materials that qualify under the limited quantity provision are permitted a further exemption in 49 CFR 172.101 (column 8A) to be reclassified as an ORM-D material under 49 CFR 173.144 and renamed with the proper shipping name "Consumer Commodity," which is defined in Appendix D. A mailable ORM-D material is additionally subject to the mailability and quantity limits in DMM C023 and this publication, as applicable. Most mailable hazardous materials fall within the ORM-D category. ORM-D materials present the lowest level of risk during transportation. The ORM-D category is unique to the United States. Its use is prohibited with international shipments of hazardous materials. It is the responsibility of the mailer to know the correct hazard class of a hazardous material prior to mailing (see 323). In those instances where assistance is needed to determine eligibility for mailing, the mailer may request a ruling from the RCSC (see 215.2 and DMM C023.1.5). 334 Small Quantity 334.1 Definition A small quantity is the maximum amount of a specific hazardous material that is not subject to any DOT requirements (i.e., packaging, marking, labeling) other than those in 49 CFR 173.4. Not every hazardous material is eligible to be shipped as a small quantity. Additionally, for postal purposes Class 7 materials are not permitted to be sent as a small quantity. The DOT small quantity provision, like the DOT ORM-D category, is unique to the United States. Its use is prohibited with international shipments of hazardous materials and cannot be used in international mail. 334.2 Mailability Hazardous materials in Class 3, Division 4.1, Division 4.2 (Packing Groups II and III only), Division 4.3 (Packing Groups II and III only), Division 5.1, Division 5.2, Division 6.1 (Packing Groups II and III only), Class 8, and Class 9 are eligible to be sent in the domestic mail under the small quantity provision only when each primary receptacle is limited to the following quantity, as applicable: a. 30 ml (1 oz) or less for liquids other than Division 6.1 (Packaging Group I) materials. b. 30 g (1 oz) or less for solids other than Division 6.1 (Packaging Group I) materials. c. 1 g (0.04 oz) or less for Division 6.1 (Packing Group I) materials. 334.3 Packaging and Marking Hazardous materials eligible to be shipped under the small quantity provision permitted in 49 CFR and 334.2 must be prepared following Packaging Instruction 10A in Appendix C. Each mailpiece that qualifies to be sent under the small quantity provision must be clearly marked on the address side with the following words: "This package conforms to 49 CFR 173.4.Inches 335 Packaging Requirements for Hazardous Materials 335.1 DOT Packing Groups Hazardous materials in Classes 1, 3-6, and 8-9 are assigned to a DOT packing group based on the degree of danger presented by the material during transport. The packing group assigned to a hazardous material is listed in column 5 of the Hazardous Material Table in 49 CFR 172.101 and in column (d) of Appendix A. Packing Group I indicates a great danger, Packing Group II a medium danger, and Packing Group III a minor danger. 335.2 Postal Packaging Instructions For mailing purposes, the packaging of a mailable hazardous material must follow the appropriate Packaging Instruction in Appendix C. The correct Packaging Instruction to use for a specific hazardous material can be determined using Appendix A. Mailers may not package or combine hazardous materials assigned to different hazard classes within a single mailpiece unless permitted by postal standard. 336 Nonmailable Materials Found in the Mailstream When any mailpiece containing a nonmailable hazardous material is found in the mailstream, the procedures in POM 139.117 must be followed if the materials present an immediate threat to persons or property. The procedures in POM 139.118 are followed when there is no immediate threat to persons or property. 34 Mailability by Hazard Class 341 Explosives (Hazard Class 1) 341.1 Definition An explosive is any substance or article, including a device, that is designed to function by explosion (i.e., an extremely rapid release of gas and heat) or that, by chemical reaction within itself, is able to function in a similar manner even if not designed to function by explosion, unless the substance or article is otherwise classed under the provisions in 49 CFR. 341.11 Class 1 Divisions Hazard Class 1 has six divisions as follows: a. Division 1.1 consists of explosives that have a mass explosion hazard. Examples are black powder, nitroglycerine (desensitized), dynamite, most types of torpedoes, and mercury fulminate. b. Division 1.2 consists of explosives that have a projection hazard but not a mass explosion hazard. Examples are certain types of fireworks, some types of detonating fuses, and some types of ammunition. c. Division 1.3 consists of explosives that have a fire hazard and either a minor blast or minor projection hazard or both, but not a mass explosion hazard. Examples are sodium picramate, some liquid and solid propellants, and some rocket motors. d. Division 1.4 consists of explosives that present a minor blast hazard. Examples are common fireworks, toy caps, empty primed grenades, and some small arms ammunition. e. Division 1.5 consists of very insensitive explosives that have a mass explosion hazard. Examples are type E blasting agents, some type B blasting agents, and very insensitive explosive substances. f. Division 1.6 consists of extremely insensitive articles that do not have a mass explosion hazard. 341.12 Class 1 Compatibility Codes Each division in Class 1 is further assigned a compatibility group code. The compatibility code consists of one letter (A-H, J-L, N, or S) that is positioned after the division number (e.g., 1.1A, 1.2C, 1.4S, etc.) and refers to the transportation and storage controls necessary to prevent potential hazards. See 49 CFR 173.52 for a more detailed description of the Class 1 compatibility codes. 341.2 Mailability, Packaging, and Marking Explosives are generally prohibited from mailing under 18 U.S.C. 1716. The following conditions apply to the mailing of explosives: a. International Mail. All explosives are prohibited. b. Domestic Mail via Air Transportation. All explosives are prohibited. c. Domestic Mail via Surface Transportation. Generally, explosives are prohibited. The only exceptions are for Division 1.4S toy propellant devices and safety fuses that have been approved by the Manager, Business Mail Acceptance, USPS Headquarters, Washington, DC prior to mailing as stated in 341.22 and DMM C023.2.0. 341.21 Nonmailable Explosives Nonmailable explosives found in the mailstream must be immediately reported in accordance with POM 139.117. Nonmailable explosives include, but are not limited to, the following: a. Common Fireworks. Fireworks are classified as Division 1.1, 1.2, 1.3, or 1.4 explosives depending on the degree of hazard. Fireworks include roman candles, skyrockets, helicopter-type rockets, cylindrical and cone fountains, pyrotechnic wheels, illuminating torches, firecrackers, salutes, and combinations of items that are designed to produce any of the aforementioned types of effects. All types of fireworks are prohibited from mailing. b. Fuses. Fuses are classified as Division 1.3 or 1.4 explosives depending on the degree of hazard. All types of fuses (except safety fuses as permitted under 341.22) are prohibited from mailing. c. Small Arms Ammunition. Ammunition is classified as a Division 1.1, 1.2, 1.3, or 1.4 explosive depending on the degree of hazard. Ammunition that is regulated as a Class 1 explosive and designed to be fired from a pistol, revolver, rifle, or shotgun, as well as associated primers and blank cartridges (including those designed for tools) and propellant powder for use in any firearm, is prohibited from mailing. 341.22 Mailable Explosives The following specific types of explosives may be mailed only when the applicable conditions are met. Full responsibility rests with the mailer to comply with DOT and Bureau of Alcohol, Tobacco, and Firearms (ATF) regulations before mailing. a. Toy Propellant Devices. The proper shipping name for a toy propellant device is "model rocket motor" or "igniters." A toy propellant device assigned UN0454 or NA0323 and classed as a Division 1.4S explosive is eligible for mailing in domestic mail via surface transportation only when prior written permission has been obtained from the Manager, Business Mail Acceptance, USPS Headquarters, Washington, DC. A device approved for mailing is subject to the following conditions: (1) Each device must be ignitable by electrical means only; contain no more than 62.5 g (2.23 oz) of propellant; and produce less than 80 newton seconds of total impulse with thrust duration not less than 0.050 second. (2) Each device must be constructed so that all chemical ingredients are preloaded into a cylindrical paper or similarly constructed nonmetallic tube that does not fragment into sharp, hard pieces; must be designed so that it will not burst under normal conditions of use; must be incapable of spontaneous ignition under 500 degrees F; and must not contain any type of explosive or pyrotechnic warhead other than a small, activation-charge parachute- recovery system. (3) Each mailpiece containing approved devices must be prepared for mailing following Packaging Instruction 1A in Appendix C. A shipper's declaration for dangerous goods is required. b. Safety Fuses (UN0105). Safety fuses consist of a core of black powder overspun with yarns, waterproofing compounds, and/or tapes. Safety fuses assigned UN0105 as a Division 1.4S explosive may be mailed in domestic mail via surface transportation only when prior written approval has been granted by the Manager, Business Mail Acceptance, USPS Headquarters, Washington, DC. Mailable safety fuses must be prepared using Packaging Instruction 1B in Appendix C. A shipper's declaration for dangerous goods is required. Note: "Fuses" are not to be confused with "fusees." Fusees are rail and highway distress signals that are nonmailable Class 4 flammable solids. c. Shotgun Hulls, Empty Casings, Nonmetallic Shotgun Hulls, or Casings Without Primers. These articles are not classified as explosives or hazardous materials under 49 CFR, and therefore are mailable subject to the applicable mailing rules. 342 Gases (Hazard Class 2) 342.1 Definition Hazard Class 2 consists of three divisions: a. Division 2.1, Flammable Gases. A material that is a gas at 68 degrees F (20 degrees C) or less and 14.7 psi (101.3 kPa) of pressure. Flammable gases also include materials that have a boiling point of 68 degrees F (20 degrees C) or less at 14.7 psi (101.3 kPa) and that are ignitable at 14.7 psi (101.3 kPa) when in a mixture of 13 percent or less by volume with air or that have a flammable range at 14.7 psi (101.3 kPa) with air of at least 12 percent regardless of the lower limit. These conditions must be established in accordance with ASTM E681-85, Standard Test Method for Concentration Limits of Flammability of Chemicals, or other approved equivalent method. The flammability of aerosols must be determined using the tests specified in 49 CFR 173.306(i). b. Division 2.2, Nonflammable, Nontoxic Gases. A material that does not meet the definition of Division 2.1 or 2.3 and exerts in its packaging an absolute pressure of 40.6 psia (280 kPa) or greater at 68 degrees F (20 degrees C). c. Division 2.3, Toxic Gases. A material that is poisonous by inhalation and is a gas at 68 degrees F (20 degrees C) or less and a pressure of 14.7 psi (101.3 kPa), or a material that has a boiling point of 68 degrees F (20 degrees C) or less at 14.7 psi (101.3 kPa). 342.2 Mailability The following conditions apply to the mailing of gases: a. International Mail. All gases are prohibited. b. Domestic Mail via Air Transportation. Flammable gases in Division 2.1 and toxic gases in Division 2.3 are prohibited. Nonflammable gases in Division 2.2 are generally permitted if the material can qualify as an ORM-D material and meet the quantity limitations and packaging requirements in 342.3 and 342.4. c.

A properly completed shipper's declaration for dangerous goods must be affixed to the outside of the mailpiece. For surface transportation, a mailpiece must be plainly and durably marked on the address side with "Surface Mail Only" and "ORM-D" immediately following or below the proper shipping name (i.e., Consumer Commodity). A shipper's declaration for dangerous goods is not required for mailable Class 8 corrosives. 349 Miscellaneous Hazardous Materials (Hazard Class 9) 349.1 Definition A miscellaneous hazardous material is a substance or article that presents a hazard during transportation but does not meet the definition of any other hazard class. Miscellaneous hazardous materials include: a. Any material that has an anesthetic, noxious, or other similar property that could cause extreme annoyance or discomfort to a flight crew member. b. Any elevated temperature material, hazardous substance, hazardous waste (other than Division 6.2 medical waste), or marine pollutant. Examples of miscellaneous hazardous materials (not all of which are mailable) include solid dry ice, magnetized materials, elevated temperature substances, environmentally hazardous substances, life-saving appliances (i.e., automobile air-bags), and asbestos. 349.2 Mailability a. International Mail. All miscellaneous hazardous materials are prohibited, except for certain magnetized materials as permitted in 349.242a and IMM 136g. b. Domestic Mail. A miscellaneous hazardous material that can be reclassed as an ORM-D material and renamed as a consumer commodity is permitted. Additionally, dry ice and magnetized materials are permitted within the specific limits provided in 349.23 and 349.24. 349.21 Nonmailable Class 9 Materials The following materials are prohibited: a. All Class 9 materials that cannot qualify as an ORM-D material except dry ice and magnetized materials. b. All magnetized materials that have a measurable magnetic field strength greater than 0.00525 gauss at 15 feet. c. For air transportation, all magnetized materials that can cause a compass deviation at a distance of 7 feet or more. d. In domestic mail via air transportation, dry ice in quantities exceeding 5 pounds per mailpiece. 349.22 Mailable Class 9 Materials A Class 9 material that can qualify as an ORM-D material is permitted in the domestic mail via air or surface transportation up to a weight limit of 25 pounds per mailpiece. All applicable 49 CFR requirements must be met. 349.23 Dry Ice 349.231 General Dry ice is primarily used to keep other items cool. The items being cooled can be either mailable hazardous materials or nonhazardous items, such as medical specimens or foods. 349.232 Characteristics and Precautions Dry ice (carbon dioxide solid) is produced by expanding liquid carbon dioxide to vapor and compacting the material into blocks. When dry ice converts (dissipates) to a gaseous form, it takes in heat from its surroundings. The resulting gas is heavier than air and can cause suffocation in confined areas as air is displaced. When dry ice is enclosed in a thick metal or other restrictive type of container, internal pressure builds up and could cause the container to rupture or explode. Mailpieces containing dry ice must be handled with care because its very low temperature (about minus 110 degrees Fahrenheit or minus 79 degrees Celsius) can cause severe burns to skin upon direct contact. 349.233 Dry Ice Mailability Dry ice is permitted to be mailed when it is used as a refrigerant to cool the content of a mailable hazardous or nonhazardous material. Packages containing dry ice must be packed in containers that permit the release of carbon dioxide gas and conform to 49 CFR 173.217 and 175.10(a)(13). Mailpieces containing dry ice are subject to the following conditions, as applicable: a. International Mail. Dry ice is prohibited. b. Domestic Mail via Air Transportation. Dry ice is permitted in quantities of up to 5 pounds per mailpiece. Mailpieces containing dry ice are subject to the conditions for Packaging Instruction 9A in Appendix C, as applicable. c. Domestic Mail via Surface Transportation. A mailpiece sent via surface transportation (i.e., at Standard Mail rates) may contain more than 5 pounds of dry ice. Mailpiece preparation is subject to the conditions for Packaging Instruction 9A in Appendix C. Note: A mailpiece that is prepared for surface transportation must not, under any circumstances, be routed via air transportation. 349.24 Magnetized Materials 349.241 Definition A magnetized material is an article that has a magnetic field strength capable of causing the deviation of aircraft instruments. Magnetized materials include magnets and magnetized devices such as magnetrons and light meters of sufficient strength to possibly cause erroneous aircraft magnetic compass readings. 349.242 Mailability Magnetized materials that have a magnetic field strength of 0.002 gauss or more at a distance of 7 feet from any point on the surface of the outer packaging are mailable via air transportation if properly packaged. Magnetized materials that have a field strength greater than 0.00525 gauss at 15 feet are nonmailable under any conditions. The following requirements also apply: a. International Mail. Magnetized materials are prohibited except for those that cannot cause a compass deviation at a distance of 7 feet or more. See 622.4. b. Domestic Mail via Air Transportation. Magnetized materials that can cause a compass deviation at 7 feet or more are prohibited. A magnetized material is mailable if it is not capable of causing a compass deviation at a distance of 7 feet or more. Mailpiece preparation is subject to the conditions for Packaging Instruction 9B in Appendix C. The address side of the outer packaging must bear the magnetized material warning label shown in Exhibit 349.242b. c. Domestic Mail via Surface Transportation. A magnetized material is not restricted by the limitation that it must not cause a compass deviation at distance of 7 feet or more (but it may not have a field strength greater than 0.00525 gauss at 15 feet). A mailpiece containing magnetized material with unconfined fields must be clearly identified on the address side with the markings "Magnetic - Keep 7 Feet Away From Navigational Equipment" and "Surface Mail Only." The preparation conditions for Packaging Instruction 9B in Appendix C must be met. Exhibit 349.242b Warning Label for Magnetized Materials Picture of label not available. 349.3 Packaging For mailable Class 9 materials, the following packaging requirements as detailed in the Packaging Instructions in Appendix C apply: a. Packaging Instruction 9A. Must be followed for mailable quantities of dry ice. b. Packaging Instruction 9B. Must be followed for mailable types of magnetized materials. c. Packaging Instruction 9C. Must be followed for Class 9 miscellaneous hazardous materials that are eligible to be re-classed as mailable ORM-D materials. 349.4 Marking and Documentation For air transportation, a mailable Class 9 material that can be re-classed as an ORM-D material must be plainly and durably marked on the address side with "ORM-D AIR" immediately following or below the proper shipping name (i.e., Consumer Commodity). A shipper's declaration for dangerous goods that is prepared in triplicate must be affixed to the outside of the mailpiece. For surface transportation, a mailable material that can be re-classed as an ORM-D material must be plainly and durably marked on the address side with "Surface Mail Only" and "ORM-D" immediately following or below the proper shipping name (i.e., Consumer Commodity). The specific marking and documentation requirements for dry ice and magnetized materials are specified in Packaging Instructions 9A and 9B in Appendix C, as applicable. 4 Restricted Matter 41 General 411 Definition Restricted matter includes articles on which certain mailing restrictions have been imposed for reasons other than risk of harm to persons or property involved in moving the mail. Motor vehicle master keys and intoxicating liquors are examples of restricted items. 412 Mailer Responsibility The mailer is responsible for ensuring that all postal requirements, as well as all federal and state laws and local ordinances that apply to the shipment of an article of restricted matter, have been met. 413 Rulings Where doubt exists about mailability of any article that is considered to be restricted matter, a request for a ruling may be made to the local postmaster (see 215.3). When the qualification of an addressee to receive restricted matter within the conditions in this chapter and DMM C024 is in question, a postmaster may require the mailer or addressee to furnish a written explanation of the addressee's eligibility and/or the item's mailability. If the explanation is not satisfactory or when uncertainty remains, the postmaster may forward the explanation along with a statement of the facts to the appropriate RCSC for a ruling. 414 Nonmailable Matter Found in the Mails All nonmailable articles of restricted matter discovered in the mailstream must be immediately reported in accordance with the provisions in POM 139.117 or 139.118, as appropriate. 42 Intoxicating Liquors 421 Definition Intoxicating liquors are potable beverages that have 0.5 percent or more alcoholic content by weight and that are taxable under chapter 51 of the Internal Revenue Service (IRS) Code. 422 Mailability 422.1 Nonmailable Matter 422.11 Intoxicating Liquors Intoxicating liquors having 0.5 percent or more alcoholic content are nonmailable. This includes taxable liquors with 3.2 percent or less alcohol, as well as those obtained under a prescription or as a collector's item. The prohibition of the mailing of intoxicating liquors is contained in federal law (18 U.S.C. 1716). 422.12 Promotional Materials Advertising, promotional, or sales matter that solicits or induces the mailing of intoxicating liquors also is nonmailable. See DMM C031.4.0. 422.2 Mailable Liquors 422.21 Products Not Categorized As Intoxicating Liquors A product containing an intoxicating liquor is mailable if it conforms to the applicable requirements of the IRS and the Food and Drug Administration (FDA) and if it is not a taxable alcoholic beverage, or poisonous or flammable. The following examples are mailable: a. Cold remedies. b. Cooking wine. c. Mouthwash. 422.22 Exempt Mailings Between Federal and State Agencies Intoxicating liquor is exempt from the prohibition against mailing when it is sent between employees of federal or state agencies who have an official use for the liquor, such as for testing purposes. This exemption is based on the intent of the law to prevent liquor from being transported to prohibited jurisdictions for consumption and to ensure that all proper tax revenues are paid. 423 Packaging and Marking 423.1 General All exempt and excepted intoxicating liquors must be sent via registered mail service and must meet the packaging requirements for liquids in DMM C010. 423.2 Denatured Flammable or Combustible Liquor There are no postal requirements to denature the contents of intoxicating liquor (i.e., to change the nature or natural qualities). However, if contents are denatured through the use of such elements as sodium bisulfate (a corrosive) or mercuric chloride (a poison), the substances must meet the mailability requirements in Chapter 3 for a Class 8 corrosive material or a Division 6.1 toxic substance, as appropriate. If the contents are flammable or combustible, the material must meet the requirements for a Class 3 flammable or combustible liquid in Chapter 3. 43 Firearms 431 Definitions 431.1 Firearm A firearm is defined as any device (including a starter gun) that is designed, or may readily be converted, to expel a projectile by an explosion, a spring, or other mechanical action, or by air or gas pressure with sufficient force to be used as a weapon. 431.2 Handgun Pistols, revolvers, and other firearms capable of being concealed on the person (for example, short-barreled shotguns and short-barreled rifles) are defined as handguns.

Certain poisonous (toxic) drugs and medicines may be subject to the requirements for Division 6.1 materials in Chapter 3. 481.3 Drug Paraphernalia The term "drug paraphernalia" refers to any equipment, product, or material primarily intended or designed for use in manufacturing, compounding, converting, concealing, producing, processing, preparing, injecting, ingesting, inhaling, or otherwise introducing into the human body a controlled substance. 482 Mailer Responsibility The mailer is fully responsible for the following: a. Ensuring compliance not only with Postal Service regulations, but also with all other federal laws and regulations, such as the Poison Prevention Packaging Act and the Consumer Product Safety Act, and with all local laws and regulations governing distribution of unsolicited samples. b. Being aware of other characteristics of an article or substance, such as its flammable, toxicity, or corrosive characteristics, that may affect its mailability. 483 Mailability 483.1 Controlled Substances If the distribution of a controlled substance is unlawful under 21 U.S.C. 801 or any implementing regulation in 21 CFR 1300, then the mailing of the substance is also unlawful under 18 U.S.C. 1716. Controlled substances and drugs that contain controlled substances are acceptable in the domestic mail only under the following conditions: a. For mailable controlled substances, generally both the mailer and addressee must meet either of the following conditions: (1) Be registered with the Drug Enforcement Administration (DEA). (2) Be exempted from DEA registration, such as military, civil defense, and law enforcement personnel, in performing official duties. b. For prescription medicines containing mailable narcotic drugs (controlled substances), only a pharmacist or medical practitioner, etc., who dispenses the medicine may mail such substances to the patients under their care. 483.2 Drugs (Other Than Controlled Substances) All prescription, nonprescription, and patent medicines and related items, including solicited and unsolicited samples of such items, that are not considered to be controlled substances under 481.1 are permitted to be mailed as follows: a. For prescription medicines containing a nonnarcotic drug(s), the mailer must be a registered practitioner or dispenser mailing to the ultimate user. b. For nonprescription medicines, the mailer must meet all applicable federal, state, or local laws that may apply (such as the Poison Prevention Packaging Act of 1970 in 15 U.S.C. 1471(2), Consumer Product Safety Commission requirements in 16 CFR 1700, etc.). 483.3 Poisonous Drugs and Medicines Poisonous drugs and medicines may be sent only from the manufacturer or dealer to licensed physicians, surgeons, dentists, pharmacists, druggists, cosmetologists, barbers, and veterinarians (18 U.S.C. 1716). Some poisonous drugs are subject to the requirements for Division 6.1 materials in Chapter 3. 483.4 Small Amounts for Law Enforcement Purposes Nothing in this section precludes the mailing of small amounts of unknown matter suspected of containing controlled substances to a federal, state, or local law enforcement agency for law enforcement purposes. Such mailings must comply with the applicable packaging requirements in 484. 483.5 Mailable Trade-Name Drugs and Medicines Rulings have been made on a number of trade-name products. The following are some examples of products previously ruled to be mailable: a. Aldifurt Balus. b. Dicumarol. c. Librium. d. Listerine Antiseptic. e. Pertussin Plus. f. Romilar CF. g. Romilar III. h. Tanel Laxative. i. Vicks Formula 44 Cough Syrup. j. Vicks Nyquil. 483.6 Drug Paraphernalia If the possession of any type of drug paraphernalia is unlawful under the Controlled Substances Act, the article is also nonmailable. See DMM C024.12.0 for more information. 484 Packaging and Marking The following conditions apply: a. Controlled substances. The inner packaging of any mailpiece containing a mailable controlled substance must be marked and sealed in accordance with the applicable provisions and regulations of the Controlled Substances Act (see 481.1). The inner packaging must be securely held within a plain outer wrapper or packaging. No markings of any kind that indicate the nature of the contents may appear on the outside of the mailpiece.

However, be alert to the fact that the composition of commercial products are ever-changing, as often displayed on product packaging that declares a "new and improved formula," etc. Because some products possess hazardous characteristics, such as flammability, requests for rulings must include the trade name of the product. A generic description of the item (e.g., tranquilizers) is not sufficient. Requests for rulings are directed to the local postmaster (see 215.3). 486 Nonmailable Matter Found in the Mails Nonmailable controlled substances, drugs, and drug paraphernalia discovered in the mailstream must be immediately reported in accordance with POM 139.117. 487 Undeliverable Medicines The disposition of undeliverable mailpieces containing drugs and medicines is governed by POM 691.52. 49 Unsolicited Promotional Samples 491 Definition The term "unsolicited promotional sample" refers to any article of merchandise that is sent through the mail free of charge and that is unrequested by the addressee. This definition includes such items as patent medicines, cosmetics, laundry products, razors, etc. 492 Mailability 492.1 General The fact that an item is unsolicited by the addressee generally does not affect its mailability unless the article is composed of hazardous materials or restricted matter. Hazardous materials are subject to the mailing conditions in Chapter 3 of this publication and DMM C023, as applicable. 492.2 Nonmailable Promotional Samples 492.21 Abortive and Contraceptive Devices or Materials Any article or thing designed, adapted, or intended for producing abortion is nonmailable (18 U.S.C. 1461). Unsolicited samples of an article or thing designed, adapted, or intended for preventing conception is nonmailable except when mailed to a manufacturer, dealer, licensed physician or surgeon, nurse, pharmacist/druggist, or a hospital or clinic (39 U.S.C. 3001 and 18 U.S.C. 1461). See DMM C024.19.0. 492.22 Restricted or Improperly Prepared Items Other types of unsolicited samples may be nonmailable for other reasons, including the following: a. The sample is an otherwise restricted item such as a toxic substance or poison subject to the hazardous materials requirements in Chapter 3 and DMM C023. b. The sample is improperly prepared for mailing, such as an inadequately packaged razor blade or a household substance that does not comply with the child-resistant packaging required in DMM C024.13.0. c. The sample is a pesticide subject to the restrictions in DMM C024.14.0 or a fragrance advertising sample subject to the restrictions in DMM C024.15.0. d. The sample is an odd-shaped item in a letter-size envelope that is prohibited under DMM C024.18.0. 493 Customer Objection to Unsolicited Matter Customers who object to receiving unsolicited matter should be advised that the Postal Service must accept any lawfully mailable matter that is properly prepared for mailing and bears appropriate postage. These customers may be directed to contact the mailer or manufacturer to have their names removed from the mailing list. Customers also may be advised they may refuse any piece of mail, either at the time it is offered for delivery or after it is delivered (if unopened), as provided in DMM D042 and POM 611. 494 Rulings In the category of promotional samples, rulings sometimes can be provided based on the trade name of an item. However, this is not always possible. A generic description, such as razor blade, cleaner, aerosol product, or drug, is insufficient information for determining mailability. To request a ruling on the mailability of restricted matter, furnish the information in 215.3 to the local postmaster. If the matter for which the ruling is being requested has the physical characteristics of a toxic substance, flammable liquid, compressed gas, or other hazardous material, a ruling should be requested under the conditions in 215.2. 5 Perishable Matter 51 Definition Perishable matter is anything that can deteriorate in the mail and thereby lose value, create a health hazard, or cause an obnoxious odor, nuisance, or disturbance under ordinary mailing conditions. Mailable perishable matter may be sent at the mailer's own risk when it is packaged as required and when it can be delivered within appropriate and reasonable time limits to prevent deterioration. Examples of perishable matter include mailable types of live animals, food items, and plants. 52 Animals 521 General Requirements The full cooperation of the mailer is essential in order to safely and effectively transport animals through the mail. The following factors are normally applied to all shipments of mailable live or dead animals: a. Protection of postal employees and the public against harm from dangerous or diseased animals. b. Protection of the mail and the environment against the following: (1) Damage to the shipping container or other mailpieces from either the animal or the refrigerant used (i.e., moisture or condensation from melting ice, or heat from dry ice). (2) Obnoxious odors and noise. c. Protection of animals against death, or protection of animal specimens against spoilage, taking into account the following: (1) Expected time in transit. (2) Expected temperature in transit (weather conditions). (3) Packaging, including insulation against impact, heat, cold, and suffocation. d. Ability of an animal to survive without food or water during transport. Live animals must be transported without food or water because liquids, moisture, and loose foodstuffs can cause damage to the shipping container, other mail, and postal equipment during transport. e. The ability of the Postal Service to provide transportation and delivery service. Mailers are urged to work with postmasters in providing advance notification of shipments of live animals. The Postal Service advises destination and transfer offices when any significant quantities of animals are moving in the mail. Postal Service field personnel should consider a 4-hour time limit on the period during which animals (especially bees, day-old poultry, and adult birds) may move in a regular closed postal vehicle. 522 Packaging and Markings 522.1 Container Construction Shipping containers for mailable live animals must, at a minimum, be made of 275-pound test, double-wall, corrugated, weather-resistant fiberboard (W5c) or equivalent. Additional requirements apply to mailable types of adult fowl and adult chickens as specified in DMM C022.3.3 and C022.3.4. 522.2 Security and Ventilation Containers must be constructed to prevent escape of animals, prevent the crushing of the container and contents during normal handling, and provide adequate ventilation for the animals at all times. 522.3 Marking Each mailpiece must bear a complete return address and be marked on the address side with a description of the contents (i.e., "Live Animals," "Live Honey Bees," etc.). A mailpiece marked "If Undeliverable, Abandon" may not be accepted for mailing. 523 Acceptance for Mailing A mailpiece containing live animals that cannot reach its destination in a viable condition should not be accepted. Factors that can be taken into consideration in assessing the viability of a mailpiece containing live animals include use of proper packaging methods that protect against suffocation and crushing during transport, expected time in transit, and very extreme weather conditions that exceed the normal weather pattern along the transportation route. This provision does not extend to postal personnel the authority to refuse mailable animals that are properly packaged or to impose local black-out periods based on temperature conditions, heavy mail volumes, etc. Postal acceptance personnel must have reasonable justification to refuse a mailpiece. Before refusing any mailpiece that contains a mailable type of animal, acceptance personnel are to confer with the manager, business mail entry at their district office or their RCSC, as appropriate. 524 Disposal Any mailpiece containing live animals that cannot be delivered to the addressee or returned to the sender within 72 hours (for live day-old poultry) or within the delivery period marked on the parcel (for other mailable animals) must be disposed of immediately. For safety reasons, dispose of mailpieces not marked with a delivery period when it reasonably appears the articles could not be delivered or returned in a viable condition. See POM 691.52 for disposal information. Also see 742.3 for the disposition of mailpieces that are refused by air carriers. 525 Nonmailable Live Animals Nonmailable types of animals discovered in the mailstream must be reported in accordance with the instructions in POM 139.118. Additionally, the mailer and the post office of mailing must be notified to prevent future shipments from being incorrectly accepted for mailing. 525.1 Live Birds Live birds, other than the type of day-old poultry specified in 526.31, are nonmailable. In addition, day-old poultry vaccinated with Newcastle disease (live virus) is nonmailable. The following are some examples of nonmailable birds: a. Canaries. b. Cockatiels. c. Emus. d. Finches. e.

When these prohibitions and restrictions render the shipment of any plant or plant product as unlawful, then those plants and plants are nonmailable. For more information, see DMM C022; Publication 14, Prohibitions and Restrictions on Mailing Animals, Plants, and Related Matter; and Publication 4, Importing Animal and Plant Products Through Overseas Military Post Offices. 562 Quarantines The USDA imposes quarantines on certain specific plants to prevent the introduction of agricultural diseases or pests into the United States and to prevent their spread from one part of the United States to another. 562.1 Types of Quarantines There are domestic quarantines that apply to the continental United States; others that apply to Hawaii, Puerto Rico, and the U.S. Virgin Islands; and others that apply to other territories and possessions. Each quarantine prevents the spread of specific diseases and pests. Any plant or plant matter that is under quarantine is nonmailable. 562.2 Specific Information Plant quarantines cover a great variety of plant diseases and pests, and all areas of the country. For more specific information, consult Publication 14, Prohibitions and Restrictions on Mailing Animals, Plants, and Related Matter. 562.3 Inspection Plants under quarantine by the USDA may be moved from the quarantine areas only after being inspected and after a permit or certificate is issued. Refer to ASM 274.9 regarding USDA inspection of mail. 563 Packaging and Marking 563.1 General Wettable packing materials and roots or butts of plants must be wrapped or boxed in a waterproof material.

Any injurious animal, the importation or interstate shipment of which is prohibited under 18 U.S.C. 42. b. Any plant pest, the movement of which is prohibited under section 103 or 104 of the Federal Plant Pest Act (7 U.S.C. 150bb or 150cc). c. Any fish or wildlife, the conveyance of which is prohibited under section 3 of the Lacey Act Amendments of 1981 (16 U.S.C. 3372). For more information, see Publication 14, Prohibitions and Restrictions on Mailing Animals, Plants, and Related Matter. 572 Criminal Penalties Criminal penalties are specified in 18 U.S.C. 1716d for mailing anything that is nonmailable under 39 U.S.C. 3015(a), (b), or (d). 6 International Mail 61 General This chapter contains information and guidelines on the mailability of hazardous materials, restricted matter, and perishable matter that may be sent as international mail. Additional information on these subjects is contained in Chapters 3, 4, and 5; the International Mail Manual (IMM) 135-139; and DMM C022-C024. The primary mailing regulations on which these guidelines are based are found in the IMM and DMM. 62 Hazardous Materials: International Mail 621 General Requirements 621.1 Mailing Conditions In international commerce, the term "dangerous goods" is commonly used to describe hazardous materials. Almost all hazardous materials are prohibited in international mail. The only mailable hazardous materials are certain infectious substances (i.e., etiologic agents and biological specimens and products), excepted quantities of radioactive material that are allowed in domestic mail, and certain magnetized materials. See Exhibit 621.1 for a summary of the types of hazardous materials that are eligible for mailing in international mail. In certain situations, the few types of hazardous materials that are generally permitted in international mail may be further restricted by the mailing limitations imposed by an individual country. Because individual countries have unique prohibitions and restrictions, it is always necessary to consult the Individual Country Listings in the IMM to be certain that an otherwise mailable hazardous material is acceptable for shipment to a specific country. Exhibit 621.1 DOT Hazard Classes and Mailability for International Mail International Mail Hazard Class Name of Hazard Class (and Division when applicable) Air Transportation Surface Transportation 1 Explosives Prohibited Prohibited 2 Gases Prohibited Prohibited 3 Flammable And Combustible Liquids Prohibited Prohibited 4 Flammable Solids Prohibited Prohibited 5 Oxidizing Substances, Organic Peroxides Prohibited Prohibited 6 Toxic Substances And Infectious Substances Division 6.1: Toxic Substances Prohibited Prohibited Division 6.2: Infectious Substances Only registered airmail letter packages per limits in 622.2 and IMM 135 Prohibited 7 Radioactive Materials Only registered airmail letter packages per limits in 622.3 and IMM 135.6 Prohibited 8 Corrosives (liquids and solids) Prohibited Prohibited 9 Miscellaneous Hazardous Materials Prohibited, except for magnetized materials per 622.4 Prohibited, except for magnetized materials per 622.4 621.2 Hazard Classes The nine classes of hazardous materials listed in 331 also apply to dangerous goods shipped in international commerce. The nonpostal regulations that govern the air shipment of hazardous materials (i.e., dangerous goods) in international commerce are specified in the Technical Instructions for the Safe Transport of Dangerous Goods by Air of the International Civil Aviation Organization (ICAO). In 49 CFR, DOT recognizes the ICAO requirements for the air transportation of hazardous materials. However, 49 CFR gives DOT the authority to regulate only the domestic transportation of hazardous materials. Generally, most air carriers follow the Dangerous Goods Regulations of the International Air Transport Association (IATA), and those regulations are slightly more restrictive than the ICAO rules. 621.3 ORM-D Materials The ORM-D category is unique within domestic commerce in the U.S. and is not recognized in international commerce. Hazardous materials that are mailable in domestic mail as ORM-D materials are prohibited in the international mail. 621.4 APO/FPO Mail Mailpieces containing hazardous materials for delivery to overseas military post office (APO/FPO) addresses are required to meet the standards that apply for shipping hazardous materials in international mail. See DMM E010.2.0. 622 Mailable Hazardous Materials 622.1 General As shown in Exhibit 621.1, almost all hazardous materials are prohibited in international mail. Under specific circumstances, only biological substances, limited amounts of radioactive materials, and certain magnetized materials are eligible to be sent in international mail. 622.2 Biological Substances, Division 6.2 Infectious and noninfectious biological substances are permitted in international mail subject to the provisions that apply to domestic mail in 346.2 and DMM C023.8.0. In addition, the following requirements apply: a. Biological substances are prohibited from international mail by certain countries. To determine if a prohibition exists for a specific country, check the Individual Country Listings in the IMM. b. Biological substances, including those of a pathogenic nature, must be sent as registered airmail letter packages. c.

Consult the Individual Country Listing in the IMM for specific restrictions or prohibitions. 7 Air Transportation Requirements 71 General This chapter contains information and guidelines on the mailability of hazardous materials, restricted matter, and perishable matter in domestic mail via air transportation. Full compliance with the regulations governing the shipment of harmful matter by air transportation is essential because these materials can endanger postal employees, airline passengers and personnel, aircraft equipment, and postal equipment and facilities. For the purposes of this chapter, air transportation requirements apply to all mailable hazardous materials, restricted matter, and perishable matter sent at an Express Mail, Priority Mail, or First-Class Mail rate of postage. 72 Hazardous Materials: Air Transportation 721 General Requirements For domestic mail sent via air transportation, a mailpiece containing a hazardous material must: a. Consist of a material that is permitted to be transported by air. b. Be prepared and packaged under all applicable conditions for transport by air. c. Be sent at an Express Mail, Priority Mail, or First-Class Mail rate of postage. Hazardous materials are not acceptable for air transportation if they are not prepared in compliance with the specific applicable requirements. These requirements consider the degree of hazard, quantity of material, method of packaging, required shipping papers, and adequacy of labels and/or markings required for carriage aboard an aircraft. Chapter 3 and the Packaging Instructions in Appendix C, along with the mailing standards in DMM C023, provide full details of the conditions under which mailable hazardous materials may be sent in domestic mail via air transportation. 722 Additional Requirements 722.1 APO/FPO Mail All hazardous materials sent to, from, or between overseas military post offices (APOs/FPOs) or sent as space available mail (SAM) or parcel airlift (PAL) service must be eligible for and properly prepared for air transportation. See DMM E010.1.0 and 2.0 for more information on air transportation restrictions affecting APOs/FPOs, SAM, and PAL service. 722.2 ZIP Codes Served Only by Air Transportation Hazardous materials that are prohibited from mailing via air transportation cannot be mailed to any ZIP Code that is serviced only by air transportation (i.e., certain ZIP Codes in Alaska). 722.3 Air Transportation Prohibitions The following types of hazardous materials are prohibited from transport via aircraft under any circumstances: a. Anything susceptible to damage or that can become harmful because of changes in temperature or atmospheric pressures unless protected against the effects of such changes. b. Magnetic material that has a field strength sufficient to cause a compass deviation at a distance of 7 feet or more from any point on the outer packaging. c. Flammable materials (gases, liquids, and solids). d. Radioactive materials. e. Hazardous materials excluded from air shipment by the regulations of 49 CFR 100-185, or by the applicable state (country) or air carrier operator variations. 723 Hazardous Materials Warning Labels See 325 for information on hazardous materials warning labels. Parcels displaying any of the DOT warning labels shown in Exhibit 325a are prohibited because items required to bear those warning labels contain hazardous materials or quantities of hazardous materials that possess too great a risk to be safely handled in the mail. Parcels displaying any of the labels shown in Exhibit 325b are permitted to be mailed within specific limits set by the Postal Service and as defined in Chapter 3 and DMM C023. 724 ORM-D Materials Hazardous materials permitted to be sent in domestic mail via air transportation must qualify as ORM-D materials, except for the few materials specified in 322 and Exhibit 331. See 333 for more information on ORM-D materials. To be acceptable for air transportation, an ORM-D material must be eligible for shipment via air and must be properly packaged and marked. The mailpiece must also bear a shipper's declaration for dangerous goods as required in 326 and 725.3. 725 Mailer Responsibility 725.1 General The mailer is fully responsible for properly determining the mailability of the hazardous material and for properly packaging and identifying the material for air transportation, as required. 725.2 Marking Requirements The following are prerequisites for any mailable hazardous materials that are to be transported aboard an aircraft. Such mailpieces must be marked, as required, with the following: a. Proper shipping name (49 CFR 172.101). b. Identification number with the appropriate United Nations (UN) or North American (NA) prefix (not required for ORM-D materials). c. Consignee's or shipper's name and address. d. Package specification markings (not required for ORM-D materials). Note: For all mailable ORM-D materials, the proper shipping name is "Consumer Commodity," and the required marking for air transportation is "ORM-D-AIR." 725.3 Shipping Papers Most mailable hazardous materials (including ORM-D materials) must be accompanied by a Shipper's Declaration for Dangerous Goods (i.e., shipping paper, see 326). To determine which mailable hazardous materials require a shipping paper when sent via air transportation, refer to the appropriate sections in Chapter 3, the appropriate Packaging Instruction in Appendix C, and DMM C023. The shipping paper must be properly completed and signed in triplicate by the mailer. It must bear a red candy-striped border and the exact format and same basic wording as shown in Exhibit 326. The shipper's declaration must be properly prepared as required by 49 CFR 172.200 through 172.204, which, in part, requires the following information: a. Proper shipping name of material. b. Hazard class. c. UN or NA identification number, as applicable. d. The quantity and type of packaging. e. The packaging instruction used. f. The full name, address, and telephone number of the shipper or consignee. g. The signed shipper's certification statement. Neither the Postal Service nor DOT stocks or furnishes shipper's declaration forms. Mailers may obtain them from commercial printers or stationery stores. 725.4 Addressing The full names and addresses of both the sender and the addressee must appear legibly on the address side of the mailpiece. 726 Postal Handling 726.1 Acceptance Personnel In addition to the basic guidelines in 251, postal personnel at window units and business mail entry units (BMEUs) must ensure the following at the time of mailing: a. Each mailpiece presented contains a mailable hazardous material that is properly packaged and labeled. b. If required, the mailpiece bears the required shipper's declaration for dangerous goods (see 326 and 725.3). c. The mailpiece is eligible for air transportation and postage is paid at the Express Mail, Priority Mail, or First-Class Mail rates, as permitted. Note: For safety reasons, mailpieces containing hazardous materials that are not eligible for air transportation cannot pay postage at an Express Mail, Priority Mail, or First-Class Mail rate and be marked "Surface Mail Only." 726.2 Dispatch Personnel In addition to the basic guidelines in 252, postal personnel involved with mail dispatch via air transportation must follow the procedures in Memorandum of Policy OS-04-21-98, Hazardous Materials and Dangerous Goods in the Mail, and the POM. This policy statement provides the interim field instructions for handling mailpieces containing hazardous materials within mail processing areas and the proper tendering of such mail to the air carriers. 727 Refusal by Air Carrier 727.1 Air Carrier Policy or Pilot's Decision Although a mailpiece containing a mailable hazardous material may be properly prepared for air transportation under postal mailing requirements, it is possible for it to be refused by an individual pilot. Nonmailable or improperly prepared mailpieces can also be rejected by an air carrier when tendered for shipment. Refusals can result from the following situations: a. The air carrier is not authorized to carry hazardous materials under the provisions of the Federal Aviation Administration (FAA) Operator's Certificate. b. The air carrier's corporate policy prohibits carrying hazardous materials. c. The pilot of an individual flight rejects any mailpieces perceived as questionable or unsafe. Pilots have the right to refuse the boarding and transport of questionable articles that could interfere or prevent the safe operation of the aircraft under the Federal Air Regulations (FAR). d. The mailpiece contains a nonmailable hazardous material that was mistakenly accepted or deposited in the mailstream. e. The mailpiece is not properly packaged, marked, or labeled for air transportation. f. The mailpiece does not carry a properly completed shipper's declaration for dangerous goods. g. The mailpiece is unidentified as to its contents and appears to contain a hazardous material. 727.2 Handling of Mailpieces Refused by an Air Carrier All mailpieces containing hazardous materials that are refused by an air carrier (and for which another air carrier cannot be found) must be handled as follows: a. If the mailpiece is damaged or leaking, contact the local facility's safety officer or designee for assistance. The procedures in Handbook EL-812, Hazardous Materials and Spill Response, must be followed. b. If the mailpiece contains a nonmailable or improperly packaged hazardous material, immediately follow the reporting procedures in POM 139.117-118, as applicable. c. If the mailpiece contains a mailable hazardous material that is intact, attempt to contact the mailer via information from the return address or shipping papers. If the mailer can be reached, advise the mailer of the available options for rerouting the mailpiece via the most expeditious means of surface transportation (if permitted for the type of hazardous material). If the mailer agrees, correct the markings on the mailpiece to read "Surface Mail Only," and immediately dispatch the mailpiece to the destination via surface transportation. d. If the mailer cannot be contacted, or if the mailer does not wish to have the mailpiece rerouted via surface transportation (i.e., due to nature of contents), or if the mailpiece cannot be rerouted via surface transportation to the delivery address, do the following: (1) Endorse the address side of the mailpiece "Refused For Air Transportation by Air Carrier" and note the name of the airline, flight number, and reason for refusal. (2) Correct the markings on the mailpiece to read "Surface Mail Only," and return the mailpiece to the sender via surface transportation (if permitted). (3) Provide the mailer with instructions on how to obtain a refund of the postage charges because service was not provided. (4) Complete PS Form 2759, Report of Irregular Handling of Mail, for internal postal information only and distribute copies to the appropriate postal offices. Do not send a copy to the mailer. Include the name and address of the mailer, the type and amount of hazardous material, and the reason for the air carrier's refusal. 727.3 Nonmailable or Improperly Prepared Mailpieces Mailpieces containing nonmailable or improperly packaged hazardous materials that were inadvertently accepted for mailing will be refused by an air carrier and returned to the Postal Service when they do not meet all applicable requirements in Chapter 3, DMM C023, and the requirements of the air carrier. 728 Spills and Leaks The standard procedures to be followed by postal personnel for dealing with spills and leaks are specified in Management Instruction EL-810-96-1, Response to Hazardous Materials Releases, and Handbook EL-812, Hazardous Materials and Spill Response. 73 Restricted Matter: Air Transportation Restricted matter includes articles for which certain mailing restrictions have been imposed for reasons other than risk of harm to persons or property involved in moving the mail. Refer to Chapter 4 for mailing information on restricted matter. 74 Perishable Matter: Air Transportation 741 General Requirements Perishable matter is any item that can readily deteriorate during normal mail transport conditions and thereby lose value, create a health hazard, or cause a nuisance or disturbance. 742 Live Animals 742.1 Basic Conditions Most mailable live animals except honeybees are permitted to be sent via air transportation. However, the ability of the Postal Service to provide air transportation is dependent on the following: a. The animal must be mailable and eligible for transport via air. b. All provisions of airline tariffs and air carriers are met. c. Air carrier equipment is available to the Postal Service and allows the safe delivery of shipments within specified and reasonable time limits. Time allowance must also be provided for delays en route in air and ground transportation. Note: Local postal personnel are not authorized to refuse the deposit of mailable live animals that are properly packaged. See 523. 742.2 Bees Only queen honeybees are permitted to be sent in the domestic mail via air transportation. See 526.2, Exhibit 526.21, and DMM C022.3.7 for more information. 742.3 Air Carrier Refusal When an air carrier is not available to the Postal Service, or when an air carrier refuses a mailable shipment of live animals or other mailable article of perishable matter because of its company policy on safety or current extreme temperature conditions, the mailpiece is returned to the Postal Service. Mailpieces returned or refused by an air carrier must be handled as follows: a. If the mailpiece is damaged or leaking, contact the local facility's safety officer or designee for assistance. The procedures in Handbook EL-812, Hazardous Materials and Spill Response, must be followed. b. If the mailpiece contains a nonmailable or improperly packaged animal or other article of perishable matter, follow the reporting procedures in POM 139.117-118, as applicable. Additionally, to prevent future shipments from being incorrectly accepted for mailing, notify the mailer and the post office of mailing of the problem. c. If the mailpiece contains mailable animals that cannot be delivered to the addressee or returned to the sender via surface transportation within 72 hours (for live day-old poultry) or within the delivery period marked on the mailpiece (for other animals), immediately dispose of it. For safety reasons, dispose of mailpieces not marked with a delivery period when it reasonably appears the articles could not be delivered or returned in a viable condition. Also dispose of, or donate to a charitable institution, any perishable matter that cannot be returned in a viable condition. See POM 691.52 for disposal information. d. If the mailpiece contains a mailable animal or other article of perishable matter that appears to be viable and can be delivered within the specified delivery period, attempt to contact the mailer via information from the return address. If the mailer can be reached, advise the mailer of the available option for rerouting the mailpiece via the most expeditious means of surface transportation (if available). If the mailer agrees, correct the markings on the mailpiece to read "Surface Mail Only," and immediately dispatch the mailpiece to the destination via surface transportation. e. If the mailer of a parcel containing a mailable animal or other article of perishable matter that appears to be in a viable condition cannot be contacted, and the mailpiece can be returned to the sender within the specified delivery period, do the following: (1) Endorse the address side of the mailpiece "Refused For Air Transportation by Air Carrier" and note the name of the airline, flight number, and reason for refusal. (2) Correct the markings on the mailpiece to read "Surface Mail Only," and return the mailpiece to the sender via surface transportation (if available). (3) Provide the mailer with instructions on how to obtain a refund of the postage charges because service was not provided. (4) Complete PS Form 2759, Report of Irregular Handling of Mail, for internal postal information only and distribute copies to the appropriate postal offices. Do not send a copy to the mailer. Include the name and address of the mailer, the type and quantity of animals, and the reason for the air carrier's refusal. 743 Perishable Matter with Dry Ice A mailpiece containing mailable matter that is packed in dry ice (carbon dioxide solid) to cool the perishable contents must meet all requirements in 349 that apply to sending dry ice in domestic mail via air transportation. For air transportation, the amount of dry ice cannot exceed 5 pounds per mailpiece. Dry ice is prohibited in international mail. Appendix A Hazardous Materials Table: Postal Service Mailability Guide The mailing information in this table is based on the DOT Hazardous Materials Table in 49 CFR 172.101 (dated October 1, 1998, and the revisions published in Federal Register 10742, dated March 5, 1999). The information is modified to identify the mailability of each hazardous material based on Postal Service mailing regulations. This table identifies the mailability of hazardous materials for domestic mail only. Almost no hazardous materials are permitted in international mail. For information on mailability in international mail, see Chapter 6 and Exhibit 621.1. In the domestic mail, generally only those hazardous materials that can be reclassed as an ORM-D material and renamed with the proper shipping name of "Consumer Commodity" are eligible for mailing subject to the postal quantity limitations. The only exceptions are for the small number of materials listed in 322. The columns in the table contain the following information: Column (a): Lists the proper shipping name of the hazardous material in roman type. Text that appears in italic type is not part of the proper shipping name of the hazardous material and is listed for descriptive or reference purposes. Some listings direct the user to the preferred proper shipping name of a material listed elsewhere in the table. The text in this column closely matches the information in Column 2 of the Hazardous Materials Table in 49 CFR 172.101. Column (b): Lists the assigned hazard class or division of the hazardous material. The entry "Forbidden" means the material may not be transported under any circumstances. The entry "n/a" means the material does not have an assigned hazard class. If this field is shaded, refer to the listing for the preferred proper shipping name cited in Column (a). The text in this column closely matches the information in Column 3 of the Hazardous Materials Table in 49 CFR 172.101. Column (c): Lists the identification (ID) number assigned to the hazardous material. The number may be either a United Nations (UN) number or a North American (NA) number. This field is shaded if Column (a) directs the user to the listing for the preferred proper shipping name of the material, or if the entry in Column (b) is "Forbidden." The text in this column closely matches the information in Column 4 of the Hazardous Materials Table in 49 CFR 172.101. Column (d): Lists the DOT Packing Group (PG) assignment for the hazardous material. Not all hazard classes have DOT Packing Group assignments. If this field contains "n/a," the material is in a hazard class that does not use Packing Group assignments. This field is shaded if Column (a) directs the user to the listing for the preferred proper shipping name of the material, or if the entry in Column (b) is "Forbidden." The text in this column closely matches the information in Column 5 of the Hazardous Materials Table in 49 CFR 172.101. Column (e): Lists the mailability of the hazardous material according to Postal Service regulations. If the entry is "Prohibited," the material is nonmailable. If the entry cites a reference to this publication or the DMM, the material is subject to those requirements and restrictions. If the entry is "Only ORM-D," the material is mailable only if it can be reclassed as an ORM-D material and renamed with the proper shipping name of "Consumer Commodity" as permitted in 49 CFR. Mailable ORM-D materials cannot exceed the postal quantity limits specified in this publication and DMM C023. The mailer is responsible for correctly determining if the hazardous material is eligible to be reclassed as an ORM-D material. If assistance is needed, the mailer may request a ruling from the RCSC as provided in 215.2 and DMM C023.1.5. If the hazardous material is mailable in the domestic mail, refer to Column (f) and (g), as appropriate, to determine the applicable postal packaging instruction in Appendix C. Column (f): Lists the packaging instruction in Appendix C that must be followed if the hazardous material is permitted in domestic mail via air transportation. This field is shaded if Column (a) directs the user to the listing for the preferred proper shipping name of the material, or if the hazardous material is prohibited from mailing as designated in Column (e). If the entry in this column is "Prohibited," the material is not permitted in domestic mail via air transportation. Column (g): Lists the packaging instruction in Appendix C that must be followed if the hazardous material is permitted in domestic mail via surface transportation. This field is shaded if Column (a) directs the user to the listing for the preferred proper shipping name of the material, or if the hazardous material is prohibited from mailing as designated in Column (e). If the entry in this column is "Prohibited," the material is not permitted in domestic mail via surface transportation.
