Where to put UN3481 label?

UN3481 labels must be prominently displayed on the outer packaging of lithium-ion batteries installed in equipment or packed with equipment during transport. The label should be placed on a contrasting background, at least 100mm x 100mm in size, and remain fully visible without obstruction. For multi-package shipments, every individual package containing UN3481 batteries requires its own label.

Understanding the Difference Between UN3480 and UN3481 for Lithium Batteries

Where must the UN3481 label be positioned?

The UN3481 label must be affixed to the outermost layer of packaging, ensuring it remains legible throughout transit. Pro Tip: Use waterproof adhesive to prevent label detachment in humid conditions. For example, solar路灯 shipments with embedded lithium batteries require labels on two opposite sides of the wooden crate.

⚠️ Critical: Labels obscured by straps or shipping marks render the shipment non-compliant, risking customs rejection.

Do UN3481 labels require specific color standards?

Yes, UN3481 labels must follow UN Model Regulations: black hazard symbols (like the lithium battery flame icon) on an orange background. The vertical “9” indicating Class 9危险品 must measure ≥12mm high. Pro Tip: Always verify label color accuracy using Pantone 151 or 165U shades to avoid inspection delays.

Battery Expert Insight

UN3481 labeling is non-negotiable for lithium batteries shipped with equipment. Proper placement on two opposing surfaces ensures visibility during handling. Always pair labels with UN-certified packaging and documented test summaries (UN38.3) to meet multimodal transport regulations. Non-compliance risks fines up to 300% of cargo value in strict jurisdictions like the EU.

FAQs

Can UN3481 labels be printed on thermal paper?

No—thermal prints fade. Use durable synthetic materials like polyester or polypropylene that withstand -40°C to +75°C temperatures.

Are UN3481 labels required for prototype batteries?

Yes, even prototypes need full compliance. Exemptions only apply to batteries under 1g lithium content per cell.
