For UN3091 P.I. 969 Lithium Metal Battery under Section II, what are the per-package limits excluding equipment?

• A. PAX = 5 kg; CAO = 5 kg
• B. PAX = 10 kg; CAO = 10 kg
• C. PAX = 5 kg; CAO = 35 kg
• D. PAX = 3 kg; CAO = 3 kg

Answer: (A)

The key idea here is the safety limit for how much lithium metal battery can be placed in a single package when shipping under UN3091, PI 969, Section II. For this section, the per-package limit excluding equipment is 5 kg for both passenger aircraft (PAX) and cargo aircraft (CAO). That means only the weight of the batteries themselves counts toward this limit, not any equipment included in the package. The other numbers would exceed this specific Section II allowance or apply to different scenarios, so 5 kg is the valid per-package maximum. If more than 5 kg of batteries need to be shipped, you’d split into multiple packages or use a different packing instruction with a higher limit.
