The United States Postal Service (USPS) has banned the mailing of any devices containing a lithium or lithium ion battery, whether in the device, in the same package or just the battery itself outside of the United States including to American Forces offices and Diplomatic offices. This is in-line with compliance with International Civil Aviation Organization and Universal Postal Union standards. Within the US, batteries can be posted but limits based on the watt-hour rating of the battery instead of the lithium content will be used. This means that devices such as mobile phones, tablets etc can no longer be shipped using USPS and other international carriers will have to be used such as UPS or Fedex as they have fire suppression systems on their planes which can cope with lithium fires but this may increase the shipping costs. Companies who have employees outside the US will now have to issue phones directly and have them carried as hand-luggage. It may also affect sites such as Ebay where electronics devices are regularly sold.
