The basic description of a hazardous material includes the hazard class, the identification number and the proper shipping name. Which one must appear first on the shipping paper?

• A. The proper shipping name
• B. Hazard class
• C. Identification number
• D. Packing group

Answer: (A)

The first thing to appear on the shipping paper is the proper shipping name because it is the primary identifier of the material. This name tells responders and carriers exactly what substance is involved, using a standardized label that applies consistently across documents and situations. The hazard class and the identification number (UN/ID number) provide important risk and regulatory information, but they describe the nature of the hazard and the official material identity in a supporting way. The proper shipping name sets the context so everyone knows what substance is being referenced before they see the specific hazard classification or number. Packing group may be included where applicable, but it does not take the place of the name.
