What must labeling on lithium battery packaging include to be compliant?

• A. The shipper's logo
• B. The required hazard labels and UN number
• C. The consignee's favorite color
• D. The air carrier's initials only

Answer: (B)

Labeling on lithium battery packaging must clearly communicate hazard information so carriers and emergency responders know what they’re handling and how to manage it safely. The essential pieces are the hazard classification labels that show it’s a dangerous good and the UN number that identifies the specific battery type. For lithium ion batteries, the UN numbers are UN 3480 and UN 3481; for lithium metal batteries, UN 3090 and UN 3091. Including both the hazard labels and the UN number ensures compliance with shipping regulations and proper handling throughout transport. Other options like a shipper’s logo, a preferred color, or carrier initials do not convey the required hazard information and aren’t adequate on their own.
