True or false: Shipping papers may include a packing group number listed as I, II, or III

• A. False
• B. True
• C. Not allowed
• D. Never specified

Answer: (B)

The information on shipping papers includes how hazardous materials are graded for transport, including the packing group, which shows hazard severity. It’s true that a packing group number may appear as I, II, or III on shipping papers. These numerals indicate the level of danger: I is the most restrictive/hazardous, II is moderate, and III is the least hazardous within the material’s classification. The packing group helps guide packaging, labeling, stowage, and emergency response, and will be listed on the shipping paper when the material has an assigned packing group. Some materials are not assigned a packing group or are exempt, in which case no packing group appears.
