Introduction
UN38.3 certification is the most critical requirement for shipping LiFePO₄ batteries internationally. Without this document, batteries cannot be transported by air, sea, or land. This article explains what UN38.3 includes and why every foreign buyer must ensure their supplier provides it.
1. Why UN38.3 Matters
The certification verifies:
- Safety under vibration
- Safety under temperature changes
- Electrical stability
- Resistance to mechanical impact
- Safety during overcharge or short circuit
It ensures that batteries will not leak, explode, or catch fire during transport.
2. Documentation Required
Every shipment should include:
- UN38.3 test report
- Test summary (TS)
- MSDS
- Battery model information
- Manufacturer name & production location
3. Who Performs the Test?
UN38.3 must be conducted by an accredited third-party lab with:
- CNAS / ILAC certification
- Standardized testing equipment
- Full traceable testing procedures
Internal factory testing is not accepted for international transport.
4. Validity and Traceability
- UN38.3 is usually valid as long as the model is unchanged
- If the cell structure changes, testing must be repeated
- Buyers should confirm the report matches the exact model purchased
Conclusion
UN38.3 is the foundation of safe LiFePO₄ battery logistics. Buyers must verify certification before importing to prevent customs rejection or transportation delays.
