UN3480 & UN3481 Lithium Battery Labels: What You Need to Know

Q: What information must appear on the label?

The label must display the UN number (e.g. UN3480 or UN3481) and a contact telephone number on the handling mark.

Q: Do the labels need to be red?

Yes. The handling mark requires a red dashed border with black symbols. Black-only versions are permitted only under limited, strictly defined exemptions.

Q: Can you supply compliant lithium battery labels?

Yes. We supply durable, compliant labels for UN3480 and UN3481 shipments, including pre-printed labels with red borders, blank synthetic labels for thermal transfer printing, and advice on suitable materials and adhesives for your application.

Shipping Lithium Batteries? Understanding UN3480 & UN3481 labelling rules is crucial for your packaging. Lithium batteries power much of the modern world, but when it comes to transport, they present serious risks—particularly fire. That's why shipments containing lithium-ion batteries fall under strict international regulations.

Whether you're dispatching a small consumer device or a large industrial battery pack, compliance is non-negotiable. Improper labelling can lead to fines, shipping delays, and, most importantly, safety hazards. Our guide delves into the specifics of UN3480 and UN3481, ensuring your labels are tough enough to survive the journey and provide undeniable visual alerts for safety.

What Are UN3480 and UN3481?

UN3480 refers to lithium-ion batteries shipped on their own. UN3481 covers lithium-ion batteries packed with or contained in equipment (e.g., a phone, laptop, or tool). These classifications fall under Class 9: Miscellaneous Dangerous Goods, and are subject to labelling and packaging requirements set by IATA (air), IMDG (sea), and ADR (road) regulations.

Which Labels Are Required?

Depending on the mode of transport and battery configuration, you may need:

Class 9 Lithium Battery hazard label (with battery/flame icon - minimum 100x100mm)
Lithium Battery Handling Mark (diamond shape with red dashed border, UN number, and contact phone number)
Cargo Aircraft Only label (mandatory for UN3480 shipped by air)
Overpack marking if shipping multiple inner packages inside a single outer container

The Materials That Keep You Compliant

Your labels need to stick and remain legible throughout the journey, often in challenging conditions. Standard paper labels won't cut it. For lithium battery shipments, robust materials are essential.

**Synthetic Materials:** Polyester, polypropylene, or vinyl are highly recommended. They are resistant to moisture, chemicals, abrasion, and temperature fluctuations.
**Strong Adhesives:** Choose a permanent, high-tack adhesive that adheres well to various packaging materials (cardboard, plastic films, etc.) and performs in the expected temperature range.

Printing Your Labels

For durable and compliant labels, you'll need the right printing method:

**Thermal Transfer:** (with a resin ribbon) is ideal if using pre-printed stock.
**Laser Printing:** Also acceptable for certain applications.
Avoid direct thermal and dye-based inkjet printers, as they don't meet durability standards for hazardous goods.

Lithium Battery Labels: Frequently Asked Questions

Q1: Can I print lithium battery labels using thermal transfer? +

A: Yes, but with a caveat. Thermal transfer printers typically print in one colour (black) and can’t produce the red dashed border required on the handling mark. To stay compliant, use pre-printed label stock with the red border and overprint the UN number and phone number using thermal transfer with a resin ribbon. This is a common and compliant solution.

Q2: What information must appear on the label? +

A: The label must display the UN number (e.g. UN3480 or UN3481) and a contact telephone number on the handling mark.

Q3: Do the labels need to be red? +

A: Yes. The handling mark requires a red dashed border with black symbols. Black-only versions are permitted only under limited, strictly defined exemptions.

Q4: Do I need to label overpacks? +

A: Yes. When multiple labelled packages are placed inside an outer container, the overpack must be marked with the word “OVERPACK” and display all required warning labels and UN numbers duplicated on the outside.

Q5: Can you supply compliant lithium battery labels? +

A: Yes. We supply durable, compliant labels for UN3480 and UN3481 shipments, including:

Pre-printed labels with red borders
Blank synthetic labels for thermal transfer printing
