Under Section I for UN3481 P.I.967 Lithium Ion Batteries, what are the per-package limits for PAX and CAO?

• A. PAX = 5kg; CAO = 35kg
• B. PAX = 10kg; CAO = 50kg
• C. PAX = 2kg; CAO = 10kg
• D. PAX = 7kg; CAO = 25kg

Answer: (A)

The main concept is that per-package weight limits for UN3481 Lithium Ion Batteries under Packing Instruction 967 are set to limit risk, and those limits differ by the type of aircraft. For shipments on passenger aircraft (PAX), the maximum weight allowed in a single package is 5 kg. For shipments on cargo aircraft only (CAO), the maximum per package rises to 35 kg. This difference exists because passenger operations require tighter limits due to in-cabin exposure risk, while cargo operations permit heavier packages under appropriate packaging and handling standards. If you need to ship more than these amounts, you’d need to split the shipment into multiple packages or adjust to stay within the limits.
