How does the Section II per-package CAO limit compare with Section I?

How does the Section II per-package CAO limit compare with Section I?

• A. Section II CAO is 5 kg; Section I CAO is 35 kg
• B. Section II CAO is 35 kg; Section I CAO is 5 kg
• C. Both CAO limits are 5 kg
• D. Section II has no CAO limit

Answer: (A)

Cargo Aircraft Only (CAO) limits are more restrictive in Section II than in Section I. Section II allows only 5 kg per package, while Section I permits up to 35 kg per package. The tighter limit in Section II reflects the greater safety controls and lower tolerance for large lithium battery shipments on cargo-only operations, whereas Section I shipments (which can be carried on passenger aircraft under regulated conditions) allow a higher per‑package weight. So the correct understanding is that Section II is 5 kg per package and Section I is 35 kg per package.
