For a liquid Category B shipment, which packaging feature is essential?

• A. No outer packaging is required
• B. An inner primary container with a leakproof cap
• C. A single glass bottle with no secondary containment
• D. A plastic bag is sufficient

Answer: (B)

For a liquid Category B shipment, preventing leakage during transit relies on a three-layer packaging system, with the inner container playing a crucial role. The essential feature is an inner primary container that is leakproof and sealed with a cap. This ensures the liquid cannot escape even if handling or the outer packaging is stressed, providing the first line of containment and protection for people and the environment. This leakproof inner container is a must-have because it directly prevents leakage at the source, which is the foundation of safe and compliant packaging. Outer packaging and secondary containment still matter, but they’re the outer layers that protect and contain any potential breach, not a substitute for a leakproof inner container. The other options fail because outer packaging alone isn’t sufficient, a single glass bottle with no secondary containment lacks the necessary secondary barrier, and a plastic bag isn’t adequate for leak protection or structural integrity.
