Lithium batteries are regulated dangerous goods (UN3480 / UN3481). A compliant supplier should be able to provide the right transport documentation for your destination and shipping method — before the cargo moves. This guide explains the documents to ask for and what each one proves.
UN38.3 test summary
UN38.3 is a mandatory series of transport safety tests for lithium cells and batteries (altitude, thermal, vibration, shock, short circuit and more). Ask for a UN38.3 test summary that covers the exact model you are buying — not a generic one. It is required for air, sea and most courier shipments.
MSDS / SDS (Safety Data Sheet)
The safety data sheet describes the battery’s composition, hazards and safe handling for transport and customs clearance. Carriers and customs brokers routinely request it.
Other documents you may need
- Dangerous Goods Declaration (DGD) — for air freight under IATA rules.
- Packing instructions — UN-spec packaging and labeling (PI965–PI970 for air).
- Certificate of Conformity / cell-safety certificates — UL, IEC 62133, CB, CE, RoHS depending on market.
- Commercial invoice & packing list — with correct HS code and UN number.
What to confirm before ordering
- Destination country regulations and import requirements.
- Shipping method (sea / air / overseas warehouse) — this changes the paperwork.
- Packaging, labeling and state-of-charge limits.
- Certification coverage for the exact model and chemistry.
A supplier that can hand you these documents up front is a strong signal of a compliant, export-ready factory. See our certifications and quality control for what we provide by model.
