Mailability

• International Mail: Permitted via Priority Mail Express International Service when permitted by the destination country (refer to the Individual Country Listings in the IMM).
• Domestic Mail: Permitted via Priority Mail Express service only.

Required Packaging

Primary Receptacle

• International: A funeral urn is required as the primary receptacle. It must be sealed and sift-proof.
• Domestic: The primary receptacle must be strong and durable and be constructed in such a manner as to protect and securely contain the contents inside and it must be properly sealed so that it is sift-proof.

Note: A sift-proof container is any vessel that does not allow loose powder to leak or sift out during transit.

Cushioning Material

• For both domestic and international shipping, the space between the primary receptacle and the outer packaging must contain enough material to keep the item stable during transit and to absorb the shock to prevent breakage.

Outer Packaging

• A strong outer packaging that is capable of firmly and securely holding the primary receptacle(s) and cushioning material is required. Refer to 339.4.
• All cremated remains mailings must utilize the USPS-produced Cremated Remains (BOX-CRE) outer packaging, found on usps.com.
• Insert the primary receptacle into a sealed plastic bag, then place in the shipping box and add padding to the bottom, sides, and top to ensure there is no movement of contents during transit.

Note: It is recommended that you attach a slip of paper to the sealed plastic bag with the complete return and delivery addresses and the words “Cremated Remains” in the event the mailing label becomes detached from the outer packaging after acceptance.

Marking

Labels and markings must be placed on the address side of the mailpiece unless specified differently in 221.1 and 325.1.

• Domestic: A complete return address and delivery address must be used.
• International: A complete return address and delivery address must be used. The mailer must indicate the contents (Cremated Remains) on the applicable customs declaration form.

Documentation

• International: If available, and when required by the destination post, the cremation certificate and any other certificates or permits should be attached to the outer packaging or made easily accessible. The sender is responsible for obtaining all the necessary documentation and permissions required by the national laws in the country of origin and the country of destination prior to dispatching these items. Refer to the Individual Country Listings in the IMM.
