Shipping power banks from China: UN 38.3, SDS, air vs sea and Amazon FBA
A power bank is dangerous goods in transport. The documents, classifications and charge-level rules that decide whether your order moves by air, by sea, or sits at the forwarder.
Power banks are among the easiest products to source and among the hardest to ship. In transport law a power bank is a lithium-ion battery, so it travels as dangerous goods. Get the paperwork right before production finishes and the goods move; get it wrong and they wait at the forwarder or are refused at the warehouse.
How a power bank is classified
| Classification | What it covers | Typical example |
|---|---|---|
| UN3480, lithium-ion batteries | Batteries shipped on their own | Power banks, including magnetic power banks |
| UN3481, packed with equipment | Batteries in the same box as, but not inside, a device | A charger kit with a spare battery |
| UN3481, contained in equipment | Batteries installed in a device | A product with a built-in battery |
Power banks are treated as batteries, so they normally ship as UN3480, Class 9. Your forwarder confirms the final entry from the SDS and the battery's watt-hour rating.
The documents every shipment needs
- UN 38.3 test summary: issued for the exact cell and pack, showing the tests passed.
- Safety Data Sheet (SDS/MSDS): 16 sections, matching the product and recently issued.
- Watt-hour rating printed on the case, for example about 37 Wh for a 10,000 mAh pack.
- Dangerous-goods declaration and Class 9 labels, prepared by a certified forwarder.
- For some air routes, a transport identification report from an approved test centre.
Ask for the UN 38.3 summary and SDS with the sample, not at shipping time. Every cell in our magnetic power bank line has its own UN 38.3 report.
Air freight: the 30% state-of-charge rule
Under IATA rules, lithium-ion batteries shipped on their own (UN3480, packing instruction 965) must be at no more than 30% state of charge, and they are generally restricted to cargo aircraft. From 1 January 2026, the 30% cap is also mandatory for batteries packed with equipment (PI 966); only batteries installed in a device (PI 967) may ship at a higher charge. Ask the factory to set the charge level before packing, and expect air freight to cost more than for ordinary goods.
Sea freight and rail
Most bulk power bank orders go by sea as Class 9 dangerous goods under the IMDG Code. Not every carrier or consolidator accepts lithium batteries, so book through a forwarder with DG experience and allow extra time for approval. Rail to Europe is possible on some routes; confirm battery acceptance first.
Amazon FBA: the dangerous-goods review
Amazon classifies lithium batteries as dangerous goods. Before an FBA shipment, you provide battery details in the listing (type, number, weight, watt-hours) and upload an SDS or exemption sheet; since 1 January 2020 Amazon has also required a UN 38.3 test summary. Power banks also need safety reports to a listed standard such as UL 2056. See certification by country for the full list.
Packaging and labels that avoid delays
- Print mAh, Wh, voltage and the manufacturer on the case.
- Protect terminals and USB ports from short circuit; pack each unit so it cannot move.
- Use strong outer cartons that pass the forwarder's drop requirements.
- Leave space on the carton for Class 9 and lithium-battery marks.
Choose cells and designs that ship well
Capacity drives watt-hours and therefore paperwork. A 10,000 mAh pack such as the S54 stays far below the 100 Wh passenger limit, which also keeps travel listings simple. Semi-solid cells improve thermal stability but follow the same transport rules; see semi-solid vs lithium polymer. For product choices, read the magnetic power bank buying guide.
Timeline checklist
- At sample: collect UN 38.3 summary, SDS and safety reports.
- Before mass production: confirm the Wh label and carton marks.
- Two weeks before shipping: send documents to the forwarder for DG approval.
- Before FBA: complete the dangerous-goods review in Seller Central.
We prepare the battery documents with every order and work with DG-experienced forwarders. Send us your destination and quantity or see our OEM / ODM service.
Rules are set by IATA, IMO and each carrier and change every year; confirm the current edition with your forwarder before booking.
