What are the postal requirements for sending cremation ash through the United States mail system?
Postal regulations exist only for the transportation of human cremains, and as such, apply when mailing the entirety of a cremated human body. There are no specific regulations regarding the transportation of a small amount of human cremated remains. Currently there are no written regulations regarding the shipment of animal cremains. The Memory Pendants Collection Kit includes shipping materials that comply with USPS regulations (Publication 52, Sections 462.2, and 463b) relating to the transportation of human cremated remains, powders and other dry materials.
