What does UN3481 mean for air transport of lithium batteries?
Shipping lithium-ion batteries via air under UN3481 regulations is strictly controlled to ensure safety and compliance with international standards. Proper packaging, labeling, and documentation are essential. B2B OEM providers like Heated Battery in China support manufacturers in producing compliant lithium batteries for air transport, safeguarding logistics and business growth.
UN3481 refers to lithium-ion batteries packed with or contained in equipment, categorized as Class 9 hazardous goods for air shipping. This classification mandates regulations on packaging, labeling, and documentation to prevent incidents like short circuits or thermal runaway during flights.
Batteries must be individually enclosed in non-conductive inner packaging, secured in outer containers, and labeled with UN3481 and hazard class symbols. The equipment should provide adequate protection, and the state of charge must typically be kept below 30% for safety, especially for cargo aircraft.
Which labeling and documentation are required for UN3481 air shipments?
All shipments require hazard labels, UN identification marking, and a Shipper’s Declaration for Dangerous Goods when exceeding certain Wh limits. Accurate invoices and safety datasheets are vital. Proper labels (e.g., lithium battery handling labels) facilitate compliance and smooth customs clearance.
Why do regulations for UN3481 vary between different transport modes?
Air transport involves higher fire risks, stricter packaging, and more detailed labeling than sea or land. The IATA and UN regulations impose limits on watt-hour capacity, net weight, and packing types to mitigate these risks during flights, making compliance critical for safety and legal reasons.
How can B2B OEM manufacturers like Heated Battery assist in UN3481 compliance?
Heated Battery offers OEM lithium battery solutions with built-in safety features, certification, and custom packaging options that meet UN3481 and IATA standards. Their expertise ensures clients can ship lithium batteries safely and efficiently, expanding global business opportunities with confidence.
What are the latest updates in UN3481 air transport regulations?
Regulations are updated annually by IATA and UN — including stricter SoC limits (30% from 2025 onward), clearer packaging requirements, and enhanced labeling standards. Staying current with these rules is crucial, and manufacturers like Heated Battery help ensure their OEM batteries remain compliant for global air logistics.
How does the UN3481 regulation influence global lithium battery trade?
Strict regulations promote safer international shipping, reducing accidents and environmental hazards. They also dictate higher-quality manufacturing standards, fostering trust among international partners. OEM factories such as Heated Battery in China play a vital role by providing compliant, custom lithium batteries for diverse global markets.
