Shipping Lithium Batteries from China to Lagos: A Practical UN38.3 Checklist

Every week we move lithium-ion batteries, power stations and solar storage units from Yiwu and Shenzhen to Lagos, Tema and Abidjan. The destination rejection rate we publish — currently under 1 percent — is not luck. It is a six-point checklist applied before the booking is confirmed.

1. UN38.3 test summary. Cells, packs and power stations each need a UN38.3 test summary issued by an accredited lab (TUV, Intertek, SGS, BV). The summary must list altitude simulation, thermal, vibration, shock, external short circuit, impact, overcharge and forced discharge results. A data sheet is not the same as a UN38.3 summary.

2. MSDS in English. A Material Safety Data Sheet aligned with GHS revision 9 or later. We translate only the headings and the emergency contact — the rest stays in English, which is what Nigerian and Ghanaian customs brokers actually need.

3. Class 9 packaging. UN-approved boxes marked with the Class 9 lithium battery hazard label and the appropriate UN number (UN3480 for cells, UN3481 for packs installed in equipment, UN3090/UN3091 for lithium metal). The packaging certificate is part of the consignment file.

4. State of Charge (SOC) for cells. Standalone cells must be shipped at no more than 30 percent SOC for sea transport. Packs installed in equipment can be higher. We confirm SOC at the consolidation point, not at the port.

5. Container choice. Lithium batteries cannot share a container with certain dangerous goods, and many carriers require a reefer set point when mixed with other cargo. We pick the container type and segregation plan before the carrier is contacted.

6. DG declaration and booking. The booking is filed as dangerous goods with full IMO declarations. Carriers charge a DG surcharge and sometimes limit slots; we lock the booking before issuing a quotation.

Skipping any of the six is what causes a destination rejection. Run them all, and the shipment clears Lagos or Tema on the first attempt.
