135 Mailable Dangerous Goods

135.1 Infectious Substances

135.11 General Conditions

Infectious and noninfectious (nonregulated) biological substances are acceptable in international mail subject to the provisions of Publication 52, part 622 under the following conditions: when they are intended for medical or veterinary use, research, or laboratory certification related to the public health; only when such materials are properly prepared for mailing to withstand shocks, pressure changes, and other conditions related to ordinary handling in transit; and under the additional conditions specified in subsections below.

  1. Category A infectious substances are not mailable. Category A infectious substances as described in Publication 52, item 346.12a are substances transported in a form capable of causing permanent disability or life-threatening or fatal disease in otherwise healthy humans or animals when exposure occurs. A Category A infectious substance is assigned the identification number UN 2814 or UN 2900, based on the known medical history or symptoms of the source patient or animal, endemic local conditions, or professional judgment concerning the individual circumstances of the source human or animal. A list of indicative examples of infectious substances included in Category A can be found in International Air Transportation Association (IATA) Dangerous Goods Regulations, Table 3.3.D.
  2. Category B infectious substances are mailable when they meet the definition in Publication 52, item 346.12a and are limited to 50 ml for liquids or 50 g for solids per mailpiece. A Category B infectious substance does not meet the criteria for inclusion in Category A. A mailpiece known or suspected to contain a Category B infectious substance must bear the proper shipping name “Biological substance, Category B” on the address side of the mailpiece and must be assigned to and marked with identification number UN 3373.
  3. Nonregulated (noninfectious) materials described in Publication 52, section 346.234 as nonregulated are mailable. Nonregulated substances do not contain infectious substances or substances that are likely to cause disease in humans or animals. Nonregulated materials are not subject to regulation as materials, but when presented for mailing, they must be properly packaged as described in Publication 52, Packaging Instruction 6G.
  4. Exempt human or animal specimens as defined in Publication 52, item 346.12d are mailable. They are not subject to regulation as materials, but when presented for mailing, they must be properly packaged as described in Publication 52, Packaging Instruction 6H.
135.12 Type of Mail

Category B infectious substances must be sent only by First-Class Package International Service using Registered Mail service. Nonregulated materials defined in Publication 52, section 346.234 and exempt human or animal specimens defined in Publication 52, item 346.12d are mailable by First-Class Package International Service when properly packaged as described in Publication 52, Packaging Instruction 6G or 6H.

135.13 Senders and Receivers

Substances identified in 135.11b must be sent only by authorized laboratories to their foreign counterparts in those countries that have indicated a willingness to accept them.

Note: Countries distinguish between infectious and noninfectious (nonregulated) biological substances and may prohibit one or the other or both. See “Prohibitions” in the Individual Country Listings.

135.3 Packaging, Marking, Labeling

135.31 Category B Infectious Substances

A material that is classified as a Category B infectious substance and that meets the definition in Publication 52, item 346.12a, must be triple-packaged as described in Publication 52, Packaging Instruction 6C, must meet the packaging requirements in 49 CFR 173.199, and must be sent only by First-Class Package International Service using Registered Mail service. Each primary receptacle containing a liquid must be leakproof and surrounded by absorbent material sufficient to protect the primary receptacle and absorb the total amount of liquid should the primary receptacle leak or break. Each primary receptacle containing a solid must be sift proof. Secondary containers for liquids must be leak proof. Secondary containers for solids must be sift proof. The primary and secondary packaging must be enclosed in a rigid outer shipping container. A single primary receptacle must not contain more than 1 liter (34 ounces) of a liquid specimen or 4 kg (8.8 pounds) of a solid specimen. Multiple primary receptacles whose combined volume does not exceed 4 liters (1 gallon) for liquids or 4 kg (8.8 pounds) for solids may be enclosed in a single secondary container. In addition:

  1. The secondary container must be marked with the international biohazard symbol shown in Publication 52, Exhibit 346.321.
  2. A primary receptacle or secondary packaging containing liquid must be capable of withstanding, without leakage, an internal pressure producing a pressure differential of not less than 95 kPa (0.95 bar, 14 psi) in the range of -40° C to 55° C (-40° F to 130° F).
  3. All mailpieces sent under DMM 601.10.17.4 must be marked on the address side with the shipping name “Biological substance, Category B” and the “UN 3373” marking as outlined in 49 CFR 173.199 (a) (5).
  4. Orientation arrows are not required on these mailpieces but may be used.
