The United States Postal Service has announced that starting November 15th, they will once again be accepting international shipments of products containing Lithium batteries. Earlier this year, USPS banned Lithium battery shipments to all international destinations as they posed a fire hazard when improperly packaged. This information is especially important for merchants hoping to send electronic products internationally. International USPS shipping many international destinations and also Army (APO), Fleet (FPO) and Diplomatic Post Office (DPO) locations.
USPS has provided a list of acceptable products that now qualify for international shipping. These products include but are not limited to: cameras, video cameras, mobile/smart phones, Bluetooth headsets, laptop computers, shavers, portable DVD players, tablets, two-way radios, GPS devices and most other small electronic devices requiring lithium batteries to operate.
It is important to note that some Lithium battery-powered products still do not qualify for international shipping. To qualify, products must adhere to IMM and DMM guidelines and must have their Lithium batteries installed in the product they are intended to power. Domestic fulfillment of Lithium battery-powered products will see no change in restrictions or regulations.
Shipwire is committed to ensuring that your order fulfillment and shipping run smoothly this holiday season so please be sure to properly identify which of your products use Lithium batteries. Make sure you follow USPS guidelines if you use Shipwire for USPS international shipping.
