A controlled substance means any anabolic steroid, narcotic, hallucinogenic, stimulant, or depressant drug in Schedules I through V of the Controlled Substances Act, 21 USC 801, et seq., and 21 CFR 1300, et seq. If distribution of a controlled substance is unlawful under 21 USC 801, et seq., and any implementing regulation in 21 CFR 1300, et seq., then distribution of such matter by mail also is unlawful under 18 USC 1716.
If distribution of a controlled substance is lawful under 21 USC 801, et seq., and any implementing regulation in 21 CFR 1300, et seq., the USPS considers such distribution by mail to constitute the mailing of matter not outwardly or of its own force dangerous or injurious to a person's life or health and accordingly mailable, subject to these standards:
a. The inner container of any package containing controlled substances is marked and sealed under the applicable provisions of the Controlled Substances Act (21 USC 801, et seq., and any implementing regulation in 21 CFR 1300, et seq.) and placed in a plain outer mailing container or securely overwrapped in plain paper.
b. If the mailing includes prescription drugs containing controlled substances, the inner container is also labeled to show the prescription number and the name and address of the pharmacy, practitioner, or other person dispensing the prescription.

It is unlawful to use domestic or international mail to transport drug paraphernalia. The term drug paraphernalia refers to any equipment, product, or material of any kind 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, possession of which is unlawful under the Controlled Substances Act. Examples of drug paraphernalia are items primarily intended or designed for use in ingesting, inhaling, or otherwise introducing marijuana, cocaine, hashish, hashish oil, PCP, or amphetamines into the human body, such as metal, wooden, acrylic, glass, stone, plastic, or ceramic pipes with or without screens, permanent screens, hashish heads, or punctured metal bowls; water pipes, chamber pipes, carburetor pipes, electric pipes, ice pipes or chillers, and air-driven pipes; carburetion tubes and devices; smoking and carburetion masks; roach clips (i.e., objects used to hold burning material that is too small or short to be held in the hand); miniature spoons with level capacities of 1/10 cubic centimeter or less; chillums; bongs; wired cigarette papers; and cocaine freebase kits.
In determining whether an item constitutes drug paraphernalia, in addition to all other logically relevant factors, these factors may be considered:
a. Oral or written instructions or other descriptive materials provided with the item that explain or depict its use.
b. National and local advertising on its use.
c. The manner in which the item is displayed for sale.
d. Whether the owner, or anyone in control of the item, is a legitimate supplier of like or related items to the community, such as a licensed distributor or dealer of tobacco products.
e. Direct or circumstantial evidence of the ratio of sales of the items to the total sales of the business enterprise.
f. The existence and scope of legitimate uses of the item in the community.
g. Expert testimony on its use.
The standards in 12.1 and 12.2 apply neither to any person authorized by local, state, or federal law to manufacture, possess, or distribute items described in 12.1 or 12.2; nor to any item that, in the normal lawful course of business, is sold through the mail and traditionally intended for use with tobacco products, including any pipe, paper, or accessory.
A household substance (39 USC 3001(f)), i.e., any matter unsolicited by the addressee, that contains a substance as defined by section 2 of the Poison Prevention Packaging Act of 1970 (15 USC 1471(2)), is permitted in the mail only if it complies with the requirements for special child-resistant packaging established for that substance by the Consumer Product Safety Commission (16 CFR 1700).
A pesticide (18 USC 1716), i.e., any matter that contains a pesticide as defined by section 2 of the Federal Insecticide, Fungicide, and Rodenticide Act (7 USC 136(u)), is permitted in the mail only if it complies with child-resistant packaging standards established by the Environmental Protection Agency applicable to that particular matter (40 CFR 157) and meets the applicable standards in C023.
A fragrance advertising sample (39 USC 3001(g)), i.e., any matter normally acceptable in the mail but containing a fragrance advertising sample, is permitted in the mail only if it is sealed, wrapped, treated, or otherwise prepared in a manner reasonably designed to prevent individuals from being unknowingly or involuntarily exposed to the sample. A sample meets this requirement if it uses paper stocks with a maximum porosity of 20 Sheffield units or 172 Gurley-Hill units treated exclusively with microencapsulated oils, and if the sample is produced so that it cannot be activated except by opening a glued flap or binder or by removing an overlying ply of paper.
A mailer who presents matter that is generally permitted in the mail under 13.0, 14.0, and 15.0 but for compliance with the specified packaging and preparation requirements may submit an accompanying written statement certifying that the matter is packaged or prepared under the applicable federal laws and postal standards. The certifying statement may be made on the mailer's letterhead, on a postage statement, or as a notice on the exterior of each item presented for mailing.
Any device powered by dry-cell batteries must have the batteries removed or deactivated to prevent activating the device in the mail. A battery with liquid electrolyte is not permitted in the mail unless it is a nonspillable type battery that meets the standards in C023.
Pens, pencils, key rings, bottle caps, and other similar odd-shaped items are not permitted in letter-size or flat-size paper envelopes unless they are wrapped within the other contents of the envelope to streamline the shape of the mailpiece and prevent damage during postal processing. If an odd-shaped item is not properly wrapped, it could burst through the envelope and cause injury to employees and damage to USPS processing equipment. Odd-shaped items that are properly wrapped within paper envelopes and sent at the First-Class Mail or Standard Mail nonautomation rates may be subject to the nonmachinable surcharge under E130 or E620, as applicable. Certain types of odd-shaped items, when properly wrapped, are permitted as automation rate letter-size mail subject to the standards in C810. Flat-size automation rate mail is subject to the uniform thickness requirement in C820.
Any article or thing designed, adapted, or intended for producing abortion is not permitted in the mail (18 USC 1461).
Unsolicited samples of an article or thing designed, adapted, or intended for preventing conception is permitted in the mail only when sent to a manufacturer or a dealer of such an article or things, to a licensed physician or surgeon, or to a nurse, pharmacist, druggist, hospital, or clinic (39 USC 3001; 18 USC 1461).
Building construction material is not permitted in the mail if the acceptance and processing is likely to harm or injure USPS employees, mail, or equipment. Factors considered include but are not limited to whether the material may pose potential storage problems at the postal facilities that may process the material; whether the volume of material may impede the flow of mail in USPS transportation or mail distribution systems; whether the volume of material may lead to security problems; and whether processing the material may create safety hazards for USPS employees.
