The United States Postal Service (USPS) joined other international agencies, including the International Civil Aviation Organization (ICAO) and the Universal Postal Union (UPU) May 16, 2012, as they prohibit products containing lithium from being sent as mail matter to and from APO, FPO and DPO locations and on international commercial air transportation flights, which will impact International and military mail.

In keeping with these requirements, USPS and the Military Postal Service (MPS) must maintain standards prohibiting the shipment of products containing lithium. USPS and the MPS are working to determine if any exceptions can be made. Further announcements will be made if any new options become available.

"We recognize this change will pose an inconvenience to our customers," said Verdar May, the operations division chief at the Military Postal Service Agency , or MPSA. "The MPS and USPS strive to provide the best possible service to our military postal patrons and their loved ones. Thank you for your continued support to our service members throughout the world."
