UN 38.3 Certification for Lithium Batteries

What is un 38.3 certification?

UN 38.3 refers to Section 38.3, Part 3 of the United Nations Manual of Tests and Criteria for the transport of dangerous goods. It mandates that lithium batteries must pass the following tests before transportation to ensure safety:

- Altitude SimULation

- Thermal Test (High and Low Temperature Cycling)

- Vibration Test

- Shock Test

- External Short Circuit

- Impact Test

- Overcharge Test

- Forced Discharge Test

If the lithium battery is not installed in or packed with equipment, it must also pass a 1.2-meter drop test.

Why is UN 38.3 Certification RequiRED?

According to the IATA (International Air Transport Association) Dangerous Goods Regulations (DGR), lithium batteries must have a UN 38.3-compliant test report issued by a third-party testing and certification body in order to be shipped as general cargo by air. Airlines will not accept shipments without this certification.

Which Products Require UN 38.3 Certification?

1. Various lead-acid batteries (e.g., automotive starter batteries, stationary lead-acid batteries, small valve-regulated sealed lead-acid batteries, etc.).

2. Various power rechargeable batteries (e.g., batteries for electric vehicles, electric road vehicles, power tools, hybrid vehicles, etc.).

3. Various mobile phone batteries (e.g., lithium-ion batteries, lithium-polymer batteries, NiMH batteries, etc.).

4. Various small rechargeable batteries (e.g., laptop batteries, digital camera batteries, camcorder batteries, cylindrical batteries, wireless communication batteries, portable DVD batteries, CD and MP3 player batteries, etc.).

5. Various primary batteries (e.g., alkaline zinc-manganese batteries, lithium-manganese batteries, etc.).
