What Is UN3481 and Why Is It Important?

UN3481 refers to the classification for lithium-ion batteries contained in equipment or packed with equipment, such as batteries inside laptops or spare batteries shipped alongside devices. This classification regulates shipping, packaging, and labeling to ensure safety in transport, especially by air, sea, and land.

How Are Lithium-Ion Batteries Classified Under UN3481?

Battery classification depends on whether batteries are contained in equipment, packed with equipment, or shipped standalone. UN3481 covers batteries inside or packed with equipment, with constraints on watt-hour (Wh) ratings and quantities, ensuring appropriate controls during shipping.

Which Packaging Requirements Must Be Met for UN3481 Shipments?

UN3481 shipments require inner packaging that fully encloses batteries and equipment, preventing movement and short circuits. Strong outer packaging and Class 9 hazard labels must be applied. Quantity limits and special provisions dictate documentation and labeling requirements to meet regulations.

Why Are UN3481 Labels and Documentation Critical for Compliance?

Proper labeling with UN3481 marks and Class 9 hazard labels alerts carriers and handlers to the contents’ risks. Complete documentation like Safety Data Sheets and Shipper’s Declarations ensure regulatory compliance and smooth transportation, minimizing risk and liability.

International bodies such as the International Air Transport Association (IATA), United Nations Economic Commission for Europe (UNECE), and national agencies like the US Pipeline and Hazardous Materials Safety Administration (PHMSA) set and enforce UN3481 transport rules.

When Do SoC (State of Charge) Limits Apply to UN3481 Batteries?

Starting January 1, 2026, lithium-ion batteries under UN3481 classification must not exceed 30% State of Charge (SoC) when transported by air unless approved otherwise. This restriction applies to batteries packed or contained in equipment to enhance transport safety.

Can B2B Electric Product Manufacturers in China Benefit from UN3481 Compliance?

Yes. Manufacturers like Heated Battery in China specialize in OEM lithium batteries engineered to meet UN3481 standards. Compliance facilitates smooth international logistics, reduces shipping liabilities, and ensures supply chain stability for forklift, golf cart, and automotive battery markets.
