Traction Battery International Shipping

Traction batteries are DG Class 9. You need a UN38.3 test report, DG packaging certificate (packaging use appraisal result), MSDS and a maritime transport appraisal; some carriers also require a battery discharge certificate (SOC≤30%), and the DG space must be booked with the carrier through a freight forwarder holding dangerous goods qualifications.HUIN International Logistics holds IMDG qualifications with all staff certified and provides one-stop document agency plus DG booking; the document cycle is about 7-15 working days.

UN3480 covers standalone lithium batteries / battery packs (e.g. battery packs, modules, cells); UN3481 covers lithium batteries contained in equipment or packed with equipment (e.g. complete units with batteries). Once the same battery is installed in equipment, the declared number may change from 3480 to 3481, with different packaging and labeling requirements. HUIN can accurately determine the UN number based on the cargo form to avoid misdeclaration and detention.

Yes, but with strict restrictions: only cell- and module-level batteries can go by air, and only on cargo aircraft (CAO, Cargo Aircraft Only); complete vehicle battery packs (PACK) are usually prohibited from air freight. Air transport requires SOC≤30%, compliant UN packaging and IATA DGR declaration.HUIN's advice: send samples and urgent after-sales items by air CAO, and batch shipments by ocean FCL DG — balancing cost and speed.

The industry standard is state of charge SOC≤30% (some carriers require even lower), applicable to both sea and air. Discharging must be done at the factory and backed by a discharge certificate attached to the declaration documents. Battery voltage must be below the safe threshold and both terminals insulated to reduce thermal runaway risk. HUIN provides discharge certificate templates and inspection verification services.

The DG packaging certificate (packaging use appraisal result) is issued by a packaging inspection body designated by customs; you submit the UN packaging test report and cargo information, and it is normally completed in 3-5 working days, with fees based on the packaging specs.HUIN provides full agency for the DG packaging certificate, processed in parallel with UN38.3 testing so sailing schedules are never delayed.

Yes, but compliance is stricter: retired / second-life batteries must be declared under special provisions (UN3480 or waste battery rules), with residual capacity tests and safety assessment reports required, and some destination countries impose separate licensing requirements for used battery imports.HUIN provides a dedicated assessment for retired battery transport — destination country policy is confirmed before booking to avoid return of cargo at port.
