Update time : 2026-09-23

Introduction to the un38.3 test Certificate

un38.3 refers to Section 38.3 of Part III of the United Nations Manual of Tests and Criteria, which is specially formulated for the transport of dangerous goods, commonly referred to as UN38.3. In accordance with the relevant provisions of the IATA Dangerous Goods Regulations (DGR), various airlines have established specific transport regulations for batteries, including but not limited to those transported separately, packed with equipment, or contained in equipment.


Importance of the Battery UN38.3 Test Certificate

As lithium batteries are widely used in mobile communication devices, electronic digital products, power products, as well as in the medical and security fields, national monitoring of lithium battery transportation has become increasingly strict. Because products containing lithium batteries, such as mobile phones and laptops, pose certain risks during transport, lithium batteries must pass the test requirements of Section 38.3 of Part III of the United Nations Manual of Tests and Criteria to effectively ensure the safety of battery air transport and prevent unsafe incidents, regardless of the mode of transport.
