Does FedEx have UN3481 labels?

FedEx requires UN3481 labels for shipping lithium-ion batteries packaged with or installed in equipment, per IATA/IMDG regulations. These labels identify batteries as Class 9 hazardous materials during transport. FedEx provides guidelines aligning with UN3481 standards but expects shippers to affix compliant labels and documentation like UN38.3 test reports.

Understanding the Difference Between UN3480 and UN3481 for Lithium Batteries

What does a UN3481 label indicate?

A UN3481 label designates lithium-ion batteries shipped alongside equipment or installed in devices. It’s mandatory for air/sea transport to meet hazardous material classification (Class 9) under IATA/IMDG rules.

Technically, UN3481 applies to batteries not exceeding 30% state of charge when packed separately with equipment. Pro Tip: Always use 1.2m drop-tested packaging with this label—FedEx may reject shipments without impact-resistant boxes. For example, a drone battery taped to its charger in retail packaging requires UN3481 labeling. But what if batteries are pre-installed? They still fall under UN3481 if removable by end-users.

How does FedEx enforce UN3481 compliance?

FedEx mandates visible UN3481 markings on two external sides of packages, coupled with a shipper’s declaration. Non-compliance triggers automated holds at sorting hubs.

Packages must show battery weight (kg), watt-hour rating, and “Lithium Ion Battery in Equipment” text. Pro Tip: Print labels at 120mm x 110mm minimum size—smaller formats often get overlooked. FedEx’s internal scanners flag shipments lacking these details, delaying delivery by 2–5 business days. Why risk it? A properly labeled 72V e-bike battery with its motor controller shipped via FedEx Express typically clears customs in <24 hours.
