Required Packaging

Primary Container

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

Cushioning Material
Outer Container

Note: It is recommended that all packages contain a slip of paper with the sender’s and recipient’s address and phone number. This will provide Postal employees with a means to contact you if the outer mailing label is damaged or found missing during transit.

Marking
Documentation
  • International: A complete and accurate customs label is required and must indicate the contents of the package. If available, the cremation certificate should be attached to the outer packaging, or made easily accessible. The sender is responsible for obtaining all the necessary permissions required by the national laws in the country of origin and the country of destination prior to dispatching these items.
