To ship cremated remains you must use USPS Priority Mail Express Cremated Remains box. You can only order the Priority Mail Express Cremated Remains box online at The Postal Store® on USPS.com®. The boxes may also be available at select retail locations for immediate shipping needs.
* Note: “Sift-proof” means loose powder can’t leak out. There are many options for storing cremated remains, from simple wooden boxes to decorative urns. USPS® recommends consulting with a licensed funeral director to help you select the best container.
