Sending Batteries Overseas
The fact that batteries are considered dangerous goods means they require special packaging, storage and adherence to a lengthy list of shipping guidelines. This is especially true when shipping batteries internationally.
This article provides tips for sending lithium or other battery-powered products (like drills and power tools) by air freight to international destinations.
Lithium-ion batteries
Batteries are dangerous goods, and if they’re hidden, undeclared, packed or labeled incorrectly, their transport can pose risks to health and safety. They’re also classed as restricted commodities, which means there are specific regulations for their shipment overseas. To ship a lithium battery (or device containing one) safely, you’ll need to fill in a Dangerous Goods Declaration and provide the necessary documents for transport. This includes a Material Safety Data Sheet and a UN 38.3 certificate, which proves that the battery passed a series of tests designed to ensure its safety during transportation.
Lithium batteries are flammable and can explode if they overheat, or if the cells short circuit. Moreover, they’re prone to thermal runaway, where one cell catches fire or explodes and triggers a chain reaction in adjacent cells. This can be extremely dangerous – and it’s why airlines restrict the movement of rechargeable batteries in cargo holds.
The good news is that the rules governing the shipping of lithium batteries overseas are relatively straightforward. Most couriers follow guidelines laid down by the International Air Transport Association, so there’s consistency across multiple carriers. And the IATA’s official guidelines include a handy flowchart to help you assign the correct UN numbers and package batteries correctly. If you’re still unsure, you can always contact a shipping specialist to help you comply with the rules.
Lithium metal batteries
The rules and regulations attached to shipping lithium batteries or devices that contain them overseas are strict, especially if you’re looking at air freight options. These batteries are considered to be Dangerous Goods (DG), so there are specific guidelines and restrictions in place that must be followed.
For example, lithium metal (non-rechargeable) cells and batteries can only be mailed internationally or to and sending batteries overseas from APO, FPO, or DPO destinations when they are installed in the equipment they operate — and only in limited quantities. When shipping lithium batteries overseas, you must ensure they are properly packaged and clearly identified as containing lithium metal or lithium-ion cells and batteries.
Additionally, all shipments must be fully packaged to protect the batteries from physical damage or short circuits during handling. This includes providing a protective layer, taping it shut, and using non-conductive tape to prevent any short circuits that could lead to fires during transit.
To ship batteries safely and in compliance with all international shipping guidelines, work with a specialised courier that specialises in lithium battery and EV battery shipping. The team at Dimerco can help you navigate the process of shipping these dangerous goods overseas – whether you’re working with an EV battery manufacturer or simply importing lithium batteries for your own business.

Packaging
As lithium batteries are considered dangerous goods, they must be packaged properly to ensure that they arrive safely at their destination. Packaging requirements vary depending on the battery type and how they are shipped. Whether they are packaged separately or inside international freight service devices, they must prevent short circuiting and must not activate during transport. In addition, they must be protected from physical damage and chemical exposure.
Lithium batteries are classified as Class 9 dangerous goods and must be shipped in a UN specification container or box. They must be packed with enough filler material to prevent shifting during transit and they should be securely fastened. In addition, the outer packaging must be made from performance materials that are designed and tested to withstand shocks and mechanical handling. These include metals, plastics, and fiberboard.
If the batteries are being sent by air, they must be packaged in accordance with IATA regulations. These rules set a maximum watt-hour rating for the batteries and limit the amount of lithium metal in each package. In addition, air shipments must be packaged in a rigid container that meets the requirements of the carrier.
For a detailed look at shipping batteries internationally, refer to the PHMSA Packing Instructions for Batteries portal or IATA’s Dangerous Goods Regulations. You can also consult a freight forwarder, such as Super International Shipping, to help you meet the packaging and shipping standards required for your international shipment.
Transport
Due to their high energy levels, lithium batteries can overheat if not handled properly and present a fire risk on the ground or in-flight. As such they are classified as Class 9 dangerous goods, which means there are a number of rules that shippers need to follow when sending them abroad.
For example, shipping batteries internationally requires that you choose a suitable outer box or container to protect them in transit. It’s generally recommended to use UN specification packagingopens in new tab, which has passed tests to ensure it can withstand drops and pressure changes. You’ll also need to pack the batteries tightly with non-conductive filler material so they can’t shift during transport.
You may also need to include additional documentation, such as a shipper’s declaration or hazardous goods label, depending on the battery type and how they are packed (loose or inside equipment). The specific guidelines will vary from carrier to carrier.
