UN38.3 Certification


N38.3 refers to section 38.3 of the Manual of Tests and Criteria (Criteria) prepared by the United Nations Committee of Experts on the Transport of Dangerous Goods on the testing of lithium batteries.

UN38.3 Certification Introduction

UN38.3 is the battery safety performance test report, and according to various domestic and foreign standards for various types of batteries for a full set of safety performance tests, for the battery manufacturers to ensure product quality and safety, in line with the standards to improve export capacity.

1) The UN38.3 test is a mandatory test to ensure that lithium batteries can be safely transported by air, sea and land.

2) The Civil Aviation Administration of China has issued the "Lithium Battery Air Transport Code" to all air transport companies, which clearly requires that lithium batteries must pass the UN38.3 test by a CNAS-approved laboratory before air and sea transport. All airlines must receive the lithium battery UN38.3 qualification report and transport appraisal before they can accept and transport the lithium battery.

Why UN38.3 certification?

Lithium batteries used for air transport must comply with the International Air Transport Association (IATA) Dangerous Goods Code and for maritime transport must comply with the International Dangerous Goods Code (IMDG) of the International Maritime Organization. According to the current regulations, the inspection report for the transportation of lithium batteries must meet the requirements of UN38.3, and provide a cargo transportation condition identification report that meets the latest version of DGR and IMDG rules. If necessary, a 1.2m drop test report should be provided at the same time.
