Documents you will be asked for: ・UN number: UN 3480 (standalone lithium-ion batteries) / UN 3481 (batteries packed inside equipment or together with equipment) ・UN 38.3 test summary, Safety Data Sheet (SDS) ・Packing list and commercial invoice must state details for freight forwarders to book space
What you should do now: 1. Request UN 38.3 Test Summary from your battery supplier—this is the basic document for booking space. 2. Confirm UN number and packing method; both determine applicable packing instructions and labeling. 3. Mark UN number, battery watt-hours (Wh), and quantity on packing list and commercial invoice, and confirm with freight forwarder the dangerous goods declaration format they require.
