Publication 52 Correction: Required Hazardous Materials Separations

In the article titled “Required Hazardous Materials Separations,” in Postal Bulletin 22600 (6-16-22, pages 9–12), the Postal Service™ published revisions planned for Publication 52, Hazardous, Restricted and Perishable Mail (Pub 52) that were based on the Federal Register notice that the Postal Service published in the Federal Register on June 6, 2022.

The published revisions included new requirements for mailers to separate, into identifiable containers, all hazardous material (HAZMAT) requiring “Hazardous” marks or labels from other mail when tendering to the Postal Service.

Additionally, the revisions reflected the Postal Service requirement that used, damaged, or defective electronic devices (such as cell phones, laptops, tablets, and cameras) packaged with or containing lithium batteries are to be mailed only via surface transportation (USPS Retail Ground®, Parcel Select®, Parcel Return Service or Ground Return Service) and to bear specified markings. This rule prohibits used, damaged, or defective electronic devices containing lithium batteries from being mailed internationally or to, from, or between Army/Air Force Post Office, Fleet Post Office, and Diplomatic Post Office (APO/FPO/DPO) destinations.

Public comments received regarding these new requirements were reviewed, and a final Federal Register notice was published on November 30, 2022. The final notice provides clarification that manufacturer-certified new or refurbished devices are excluded from the definition of “used,” and specific remote ZIP Code™ locations that are serviced by air transportation only are exempt from text-marking and surface-transportation requirements.

This article, which replaces the previously published article, includes these new revisions based on the final Federal Register notice. Although these revisions will not be published in Publication 52 until the next edition, the standards are effective immediately.

2 General Guidelines

* * * * * 

[Revise the title of subchapter 25 to read as follows:]

25 Basic Guidelines for Postal Service Personnel

251 Guidelines for Acceptance Personnel

[Revise the text of 251 to read as follows:]

Postal Service 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 (e.g., 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). This process must include a thorough inspection of all sides of the mailpiece for evidence of hazardous materials (e.g., markings). At retail units, mailers must be asked the question: “Do any of your articles contain anything liquid, fragile, perishable, or potentially hazardous, such as lithium batteries, perfume, mercury, or aerosols?”

b. If the contents are mailable, determine the specific quantity limitations, labeling, and packaging requirements that apply.

c. With the exception of destination-entered mail entered at a destination delivery unit (DDU), destination sectional center facility (DSCF), or destination network distribution center (DNDC), verify that all mailpieces containing mailable hazardous materials are presented separately from mailpieces not containing hazardous materials.

d. Refuse (as permitted in POM 139) to accept material that does not meet applicable requirements for mailing and refer the circumstances to the local postmaster or PCSC for a mailability ruling under 213 or 215, as appropriate.

e. If a mailpiece containing a diagnostic (clinical) specimen is in a sack or tub, PS Tag 44 must be attached to ensure that the sack or tub will be emptied at the processing point.

f. With the exception of destination-entered mail entered at a DDU, DSCF, or DNDC, ensure mailpieces containing hazardous materials remain separated from other mailpieces and are placed into labeled containers further separated by transportation type. See 327.1a and 327.1b.

g. See 253 for guidance regarding hazardous materials found in lobby drops or retail collection boxes.

See Chapter 7 for guidelines Postal Service acceptance personnel must follow when handling hazardous materials, restricted matter, or perishable matter to be transported by air.

252 Guidelines for Dispatch Personnel

* * * * * 

[Add new item b. to read as follows and renumber current item b. as item c.]

b. Ensure that all mailpieces with a hazardous-materials mark or label are separated from all other mail and are placed into labeled containers further separated by transportation type. See 327.1a and 327.1b.

* * * * * 

[In renumbered item c., revise bullet (5) to read as follows:]

(5) If the mailpiece contains a material believed to be nonmailable, remove it from the mailstream and treat it in accordance with POM 139.117-118, as appropriate.

* * * * * 

[Add new part 253 to read as follows:]

253 Guidelines for Delivery and Collection Personnel

Delivery and collection personnel must follow these procedures when delivering and collecting mail:

a. Conduct a thorough examination of all sides of the mailpiece for hazardous-material labels and markings or any nonmailable hazardous characteristics (e.g., prohibited marks or labels). If the mailpiece is nonmailable, leaking, or stained, do not collect it; notify the customer if present, and contact the supervisor.

b. Ensure that mailable hazardous materials are separated from all other mail.

327 Transportation Requirements

327.1 General

* * * * * 

[Revise the text of items a. and b. to read as follows:]

a. Air Transportation. When eligibility for air transportation is sought, mailable hazardous materials eligible for air transportation per subchapter 34 must be sent as Priority Mail Express, Priority Mail, or First-Class Mail. Mailpieces must be prepared to meet all requirements that apply to air transportation. 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.

    Note: Mailable hazardous materials that are prohibited from air transportation may not be sent as Priority Mail Express, Priority Mail, or First-Class Mail.

b. Surface Transportation. All mailable hazardous materials eligible to be sent as First-Class Package Service, USPS Marketing Mail, USPS Retail Ground, Parcel Select, or Parcel Return Service must be prepared under the requirements that apply to surface transportation. A mailpiece containing mailable hazardous material with postage paid at First-Class Package Service, USPS Marketing Mail, USPS Retail Ground, Parcel Select, or Parcel Return Service prices must not, under any circumstance, be transported on air transportation, except for 5-digit air-only destinations identified in 327.2g.

327.2 Air Transportation Prohibitions

[Revise the introductory paragraph to read as follows:]

All mailable hazardous materials sent as Priority Mail Express, Priority Mail, or First-Class Mail must meet requirements for air transportation. The following types of hazardous materials are always prohibited on air transportation, regardless of class of mail:

* * * * * 

[Add new item g. to read as follows and renumber current item g. as item h.]

g. Used, damaged, or defective electronic devices (excluding devices that are new in original packaging, and manufacturer-certified new or refurbished devices) containing or packaged with lithium batteries (see 349.12e). For those ZIP Codes that are air transportation only due to the absence of ground transportation, a multimodal-transportation solution may be used to transport used, damaged, or defective electronic devices containing or packed with lithium batteries. See Appendix F for a list of 5-digit ZIP Codes where this exception applies.

* * * * * 

[Add new part 329 to read as follows:]

329 Presentation of Hazardous-Materials Mailings

With the exception of destination-entered mail entered at a DDU, DSCF, or DNDC, each mailer of mailable hazardous materials requiring a label or marking must do the following:

a. Present mailpieces containing hazardous materials separately from any mailpieces not containing hazardous materials. Where mailpieces are tendered in containers, pallets, or other mail transport equipment (see Handbook PO-502, Mail Transport Equipment), hazardous-materials mailpieces must be presented in a separate receptacle from non-hazardous-materials mailpieces.

b. Clearly mark an exterior side of all receptacles containing hazardous-materials mailpieces as “HAZMAT.”
