UN 38.3 Battery Testing for Air Freight from China
2 resources tagged with "Un38.3"
UN 38.3 is the mandatory transport safety standard for lithium cells and batteries, made up of 8 tests including altitude simulation, thermal cycling, vibration, shock, and external short circuit. Without a valid UN 38.3 test summary, airlines and freight forwarders will not accept LiPo or Li-ion shipments out of China, and the cargo gets held. Testing at an accredited lab typically takes 2-4 weeks and costs in the rough range of a few hundred to a couple thousand USD per cell model.
When you source batteries from China, the documentation that actually moves the goods is the UN 38.3 test summary plus a dangerous-goods declaration. We confirm the test report covers the exact cell model and capacity shipping, since a report for a sibling cell will be rejected.

FAQ
How many tests are in UN 38.3?
Eight: altitude simulation, thermal test, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge. All must pass for the cell or battery to ship by air.
How long does UN 38.3 testing take and what does it cost?
Typically 2-4 weeks at an accredited lab. Cost varies by cell type but commonly runs from a few hundred to a couple thousand USD per model, plus retesting if the design changes.
Can I ship batteries from China by air without UN 38.3?
No. Airlines and forwarders require a valid UN 38.3 test summary and dangerous-goods paperwork. Cells without it are refused at acceptance, not at customs.
