UN38.3 and MSDS: the battery papers without which cargo won't fly

UN38.3 and MSDS: the four lithium-battery documents a Class 9 robot needs to fly. Who issues each, what is inside, and where they get forged.

Good news: a proper manufacturer already has the full package — the batteries were certified long ago and the papers sit in the export manager's folder. Bad news: a middleman with no factory access does not have them, and that is where the creativity starts.

UN38.3 Test Summary

Battery test summary: eight tests from altitude simulation to short circuit. Issued by an accredited lab and tied to a specific cell model and revision.

MSDS / SDS

16-section safety data sheet: composition, transport, emergency response. Carriers and customs read sections 14 and 9 — make sure they are filled in, not “N/A”.

Dangerous goods declaration

Shipper's Declaration for air freight (IATA DGR). Prepared by the shipper or a DG-licensed agent — your regular forwarder may not have the licence.

Package marking

UN3481/UN3171 labels, Class 9 mark, responsible person's phone. A wrong sticker means the cargo is pulled off the flight even with perfect papers.

on the box
Forgery usually lives in the UN38.3: one file “covering all models at once”. That does not exist — the summary is tied to a cell and a revision.

A file with no model number or revision

A Test Summary without the exact cell part number is waste paper. At the border it gets checked against the battery nameplate.

“We'll send the documents after payment”

The package exists before the money or it does not exist at all. No exceptions to this rule.

“We'll ship it as regular electronics”

Saving $200 on proper paperwork versus cargo impounded at the port plus the carrier's fine. A bad trade.

Takeaway

Cost and timing

If the factory has the papers, copies cost $0–150 and one request. If not, testing takes 2–4 weeks and $1–3k per model — and you want to learn that before the contract, not on shipping day. In our pipeline the battery package is verified at FAT: a machine without papers simply does not leave for the port.
