When shipping cremains, what must be done to the box containing them?

When shipping cremains, it is essential that the container is securely sealed with tape. This requirement is primarily to ensure the integrity of the box and to prevent any accidental opening during transport. Sealing the box helps to protect the contents and maintains the dignity of the remains being sent. Additionally, proper sealing also complies with postal regulations, which often mandate that packages must be closed securely to prevent spillage or exposure.

While other options may suggest alternatives for packaging or containment, sealing with tape is a standard practice that provides the necessary assurances for handling and transit. This step is crucial not only from a legal perspective but also as a matter of respect for the deceased and the wishes of their family.
