Which statement is true about Packing Type and Capacity?

• A. They are limited only by the maximum packaging size.
• B. They are limited to the material being shipped, plus packing group restrictions and mode constraints.
• C. They are unlimited.
• D. They are determined by the shipper's preference.

Answer: (B)

Packing Type and Capacity are defined by three factors: the material being shipped, the packing group restrictions, and the mode of transport. The material’s hazard class and packing group determine what kinds of packaging are permitted and how strong or protective the container must be. The packing group rating specifies the level of danger and the corresponding performance requirements for the packaging. The mode of transport then adds its own constraints—different modes have different rules about what packaging is allowed, how much can be inside, and how it must be prepared for that mode. Because of these combined requirements, you can’t rely on size alone or on shipper preference; the packaging must be appropriate for the material, meet packing group standards, and comply with mode-specific regulations. That’s why the true statement is that packing type and capacity are limited to the material being shipped, plus packing group restrictions and mode constraints.
