Which label might be required on a package containing lithium batteries if applicable?

• A. Keep Upright
• B. Fragile
• C. Cargo Aircraft Only
• D. Recyclable

Answer: (C)

When shipping lithium batteries by air, some packages must be moved only on cargo aircraft due to safety rules. In those cases, a label reading “Cargo Aircraft Only” is required on the outer packaging. This flag tells handlers and airlines that the shipment cannot be loaded onto passenger aircraft and must be treated as a cargo-only shipment, aligning with dangerous goods requirements. Other labels like “Keep Upright,” “Fragile,” or “Recyclable” don’t reflect air-transport restrictions for lithium batteries and aren’t relevant to this regulation. The label would be used if the particular lithium battery shipment falls under rules that restrict it to cargo aircraft.
