USPS is the only postal service that can be used to send packages to APO/FPO/DPO locations.

But you can overcome USPS shipping restrictions and deliver lithium batteries to APO and FPO addresses using Fedex or DHL. You will need to ship to specific locations like a specific battalion at Bagram Air Base. So you will need to use the name of the base, city, country, additional identifying information such as building number or barracks number, a contact name and phone number, and if possible, an email address.
