Hazmat shipping papers should include what information about the materials? (ISHP)

• A. Identification number
• B. Proprietary name
• C. Shipping route
• D. Date of entry

Answer: (A)

The essential item on hazmat shipping papers is a unique identification number for the material. This UN/NA identification number ties directly to regulatory tables and emergency response guides, so anyone handling or responding to a incident can quickly pull up the exact substance and its safety and handling instructions. The combination of the identification number with the proper shipping name, hazard class, and packing group gives a precise, universally understood description of what’s being transported, which is critical for safe loading, routing, and emergency response.

Proprietary names aren’t required on the shipping papers because the documents emphasize the official shipping name and the UN/NA number to ensure universal recognition. Shipping route information isn’t a standard field on hazmat shipping papers; routing is a logistics detail, while the paper focuses on identifying the material and its hazards. Date of entry isn’t a typical requirement either on these papers, which are designed around identification, classification, and quantity for safe handling and regulatory compliance.

So, the identification number is the best answer because it directly identifies the material in a way that supports safety, regulation, and emergency response.
