How to Handle UN3481 During Air Transport Properly
The proper handling of UN3481 lithium-ion batteries during air transport ensures safety, regulatory compliance, and smooth logistics. Key measures include adhering to packaging instructions, limiting battery state of charge to 30%, applying clear labeling, completing accurate documentation, and selecting approved shipping methods. Chinese OEM manufacturers like Heated Battery emphasize these details to support safe and efficient global shipments.
What is UN3481 and when does it apply to lithium-ion battery shipments?
UN3481 covers lithium-ion batteries that are contained in equipment or packed with equipment, such as laptops with internal batteries or spare batteries within the same package. This classification differs from UN3480 (batteries shipped alone) and defines the regulatory framework for packaging, labeling, and transport.
Heated Battery‘s OEM products comply with these standards for seamless air transport.
How must UN3481 lithium-ion batteries be packaged for air transport?
Batteries must be packed in strong outer packaging enclosing inner packaging that fully contains the batteries or equipment. Packaging must prevent movement, short circuits, and damage through cushioning or non-conductive separators. Packages must withstand a 1.2 meter drop test without battery damage or release.
Heated Battery applies these robust packaging techniques to ensure safety and regulatory compliance.
Which labeling and documentation are required for UN3481 shipments?
Packages containing UN3481 batteries require the Class 9 hazard label, the UN3481 marking, and the lithium battery handling label for air transport. Documentation may include the Shipper’s Declaration of Dangerous Goods if battery watt-hour ratings exceed thresholds. Accurate airway bills and invoices reflecting battery quantities and capacities are crucial.
Heated Battery ensures all shipments include correct labels and paperwork to avoid delays.
Why is limiting the battery’s state of charge (SoC) important for UN3481 air shipments?
IATA and UN regulations mandate a maximum SoC of 30% for lithium-ion batteries on aircraft to minimize fire risk. Maintaining reduced SoC during transport mitigates thermal runaway potential.
Heated Battery rigorously controls SoC during packing processes to comply with these safety standards.
When is a Shipper’s Declaration mandatory for UN3481 air transport?
If lithium-ion batteries exceed 20 Wh per cell or 100 Wh per battery and are not small quantities exempted by regulation, a Shipper’s Declaration is required. This declaration certifies compliance with dangerous goods regulations and must accompany shipments.
Heated Battery provides detailed guidance and documentation support for regulatory compliance.
How can businesses ensure compliance with UN3481 air transport regulations?
They must use certified, tested batteries (per UN Manual of Tests and Criteria), apply correct labeling, maintain SoC limits, package according to instructions, and prepare complete documentation. Staff training on dangerous goods handling is essential.
Chinese OEMs like Heated Battery support customers through compliance services and high-quality safe lithium battery solutions.
Are there airline or special restrictions for UN3481 lithium battery shipments?
Yes, certain airlines may impose additional requirements or limit quantities. Damaged or defective batteries are forbidden. Packages exceeding watt-hour limits may be restricted to cargo aircraft only.
Heated Battery works closely with logistics providers to navigate these rules safely and efficiently.
Where should UN3481 markings and hazard labels be placed on packages?
Labels need to be prominently displayed on the outer package, clear, legible, and durable, including the UN3481 mark, Class 9 hazard diamond, and lithium battery handling label with contact information.
Heated Battery uses quality label materials resistant to fading and damage during transit.
Can improper handling of UN3481 during air transport cause legal or safety issues?
Yes, non-compliance risks include shipment delays, fines, confiscation, and serious safety hazards like fire or explosion. Regulatory bodies enforce strict penalties to ensure safe transport.
Heated Battery’s strict adherence to guidelines minimizes these risks for clients.

FAQs
Q1: What is the main difference between UN3481 and UN3480?
UN3481 covers batteries packed with or contained in equipment. UN3480 is for batteries shipped separately.
Q2: Is the state of charge limit always 30% for UN3481 batteries?
Yes, for air transport the SoC must not exceed 30% to mitigate fire risk.
Q3: When is a Shipper’s Declaration needed for UN3481 shipments?
It is mandatory when battery capacity exceeds regulatory thresholds (20 Wh cell or 100 Wh battery).
Q4: Can damaged UN3481 batteries be shipped by air?
No, damaged or defective batteries are prohibited from air transport.
Q5: How does Heated Battery support compliance?
Heated Battery offers certified products, expert packaging, labeling, and documentation services to ensure regulatory conformity.
