According to civil aviation regulations, airlines and airport cargo consignment departments must review the transportation documents for lithium batteries, with the most important being the UN38.3 safety testing reports for each type of lithium battery. These reports can be provided by third-party testing institutions designated by the civil aviation authority, or by battery manufacturers with testing capabilities. If such testing reports cannot be provided, the civil aviation authority will prohibit the transportation of lithium batteries.
Strict Requirement: If such testing reports cannot be provided, the civil aviation authority will prohibit the transportation of lithium batteries.
✈️
Passenger Flight Transportation
Applicable to small lithium batteries, with more stringent packaging and labeling requirements, usually limiting battery capacity and quantity.
- Lithium metal batteries: ≤2g lithium content
- Lithium-ion batteries: ≤100Wh
- Appropriate packaging and labeling required
🚛
Cargo Flight Transportation
Applicable to large-capacity lithium batteries and bulk transportation, with more packaging options and transportation restrictions.
- Greater capacity battery transportation
- Batch transportation solutions
- Professional dangerous goods packaging requirements
UN38.3 Safety Testing Requirements
UN38.3 is a testing standard for the transportation safety of lithium batteries, as specified in the United Nations Recommendations on the Transport of Dangerous Goods. It includes 8 strict safety tests:
T1 Altitude Simulation Simulation of low-pressure environment at flight altitude
T2 Thermal Testing Battery performance testing under high-temperature conditions
T3 Vibration Vibration testing during transportation
T4 Impact Simulation of impact during transportation
T5 External Short Circuit Safety testing under external short circuit conditions
T6 Impact Impact testing with heavy objects
T7 Overcharging Safety under overcharging conditions
T8 Forced Discharging Testing under forced discharging conditions
