USPS is amending the Domestic Mail Manual
(DMM) and 39 CFR to clarify that the regulations for mailing hazardous materials are found in Publication 52, Hazardous, Restricted, and Perishable Mail.
Read the Final Rule
USPS removed its regulations for hazardous, restricted, and perishable materials from the Domestic Mail Manual
(DMM) in 2014 to reduce the size of the manual and moved them to Publication 52.
Publication 52 is available online
The Final Rule also lists a variety of publications and memoranda that USPS uses to create new regulations. These includes Publication 52
as well as the DMM
, the Postal Operations Manual
, the International Mail Manual
, circulars, handbooks, management or regional instructions, memoranda of policy, and more.
In the Rule, USPS clarifies what makes something a USPS regulation:
“...status as regulations depends not on the formal designation of the document, but on its statement of binding rules of future effect beyond those stated elsewhere in the Postal Service regulations.”
Enforceable USPS regulations are not necessarily codified in the Code of Federal Regulations, although they may be.
