What are the rules for UN3481?
UN3481 regulations govern lithium-ion batteries shipped installed in equipment or packaged with devices under international transport standards. These batteries require Class 9 hazardous labels, UN38.3 safety certification, and specific packaging thresholds (≤100Wh per battery pack for non-DG containers). Mandatory documentation includes MSDS, dangerous goods declaration, and UN-approved packaging certification for DG shipments.
Understanding the Difference Between UN3480 and UN3481 for Lithium Batteries
How does UN3481 classification differ from UN3480?
UN3481 applies to batteries integrated with devices (e.g., power tools), while UN3480 covers loose battery packs. This distinction impacts packaging rules—UN3481 allows combined equipment/battery shipments without separate hazardous categorization if under 100Wh.
What packaging standards apply to UN3481 shipments?
Batteries exceeding 100Wh capacity require UN-certified DG containers with flame-retardant liners. Below 100Wh, non-DG boxes suffice if preventing short circuits through individual plastic sleeves or terminal covers.
| Capacity Threshold | Packaging Type | Labeling |
|---|---|---|
| <100Wh | Standard box | UN3481 mark only |
| >100Wh | UN-certified DG | Class 9 + UN3481 |
For example, a 200Wh camera battery pack shipped inside the device needs DG containerization. Pro Tip: Use anti-static foam between battery compartments to meet IEC 62133 padding requirements.

FAQs
No—laptop batteries under 100Wh installed during manufacturing only need the UN3481 mark on outer packaging, not Class 9 labels.
Can UN3481 batteries be airfreighted without DG certification?
Only if ≤2.7Wh per cell/≤20Wh per pack under IATA PI 967 Section II. Larger capacities require full DG air waybill declarations.
