Your Outer Container

The outer container must be strong, durable, and siftproof. We recommend that you line the shipping box with plastic or other material that will prevent leakage in case of damage. Insert your inner container into the shipping box and add padding to the bottom, sides, and top to prevent movement. Make sure there is no movement of contents within the shipping box.

Before closing and sealing the shipping box, add a slip of paper with both the sender’s and addressee’s address and content information. If, for any reason, the address label on the box is obscured or lost, postal employees will still be able to identify the sender and receiver of the package.

We recommend you use a Priority Mail Express box. The Postal Service offers the boxes free to customers who use Priority Mail Express service.
