Starting May 16, 2012, the U.S. Post Office will stop international shipping of lithium batteries and devices containing lithium batteries because they are a fire hazard. Many electronic devices, such as cell phones and cameras, use these types of batteries.
The ban includes international shipping to military addresses.
However, you can continue to ship lithium battery devices from overseas to the United States, within the U.S., and to U.S. military addresses. The Post Office anticipates that the ban will end on January 1, 2013 with the introduction of new standards for safe shipping of lithium batteries.
