There have been recent changes to mailing standards when mailing primary and secondary lithium cells or lithium batteries internationally, or to and from APO, FPO, or DPO destinations. The Postal Service™ is committed to educating our employees and customers to ensure that dangerous and prohibited items are prevented from entering the mailstream.
We have developed new international posters, notices, and job aids to show items (and quantities) where lithium batteries are permitted in the mailstream. Employees can use these materials to assist customers in determining if their package meets Postal Service, Department of Transportation (DOT), and Federal Aviation Administration standards.
One copy each of the following materials was recently mailed to every Post Office™, branch, station, processing plant, and contract station. Additional quantities are available through the Material Distribution Center (MDC). Order from the MDC using the touch-tone order entry (TTOE) system: Call 800-273-1509.
Note: You must be registered to use TTOE. To register, call 800-332-0317, option 1, extension 2925, and follow the prompts to leave a message. (Wait 48 hours after registration before placing your first order.)
