The Postal Service is amending Publication 52, Hazardous, Restricted, and Perishable Mail (Pub 52) by requiring mailers to solely use the Cremated Remains shipping supplies provided by the Postal Service when mailing human or animal cremated remains, also referred to as cremains or ashes, domestically or internationally.The Postal Service will require mailers shipping human or animal cremated remains in any state (e.g. ashes, keepsakes and jewelry) to be shipped in the Cremated Remains packaging supplied by the Postal Service. Previously, mailers were permitted to use any box if it was marked with Label 139 Cremated Remains.

The Postal Service understands the mailing of cremated remains is a sensitive matter and believes this will improve visibility and enhance handling methods throughout processing and transportation.
