Beyond whole vehicles, standalone traction-battery exports are becoming a business of their own — overseas repairs, battery swaps and storage conversions all need them. But lithium batteries are Class 9 dangerous goods with higher compliance bars than cars. Here's the core certification and transport map.
1. Required Certificates & Documents
| Item | Content | Where needed |
|---|---|---|
| UN38.3 | Lithium battery transport safety tests (8 tests) | Air / sea / land |
| MSDS | Safety data sheet | Booking |
| DG packaging cert | UN-spec packaging use appraisal | Sea freight |
| SOC limit | Charge state usually ≤30% for transport | Sea safety |
| Destination approval | CE / UN / EAC local market access | Customs & sales |
2. Choosing Transport Mode
- Sea FCL: The mainstream route — declared as Class 9 DG with DG-licensed carriers; book 2-3 weeks ahead.
- Sea with vehicle: Battery installed in the car, declared under EV dangerous-goods flow; mind SOC and insulation.
- Air: Only small cells with strict packaging — traction batteries practically can't fly; distrust agents who promise otherwise.
- China-Europe rail: Rules are loosening; some lines now carry lithium batteries — a middle-speed option for Europe.
3. Operational Risk Points
- Packaging: UN-spec packaging plus appraisal certificate — bad packaging is the top seizure cause.
- Battery condition: Swollen or leaking cells must never ship; inspect and photograph each pack.
- Document consistency: MSDS, packaging cert and customs description must match exactly.
- Insurance: Standard cargo cover often excludes DG — declare the goods' nature when insuring.
Shunwei Auto tip: Build a standard document pack — UN38.3 report + MSDS + packaging cert — filed and reused. Repeat shipments of the same model drop document prep from a week to a day.
Warning: Shipping lithium batteries undeclared as general cargo is a serious violation — a thermal-runaway incident exposes the owner to massive claims and criminal liability.
