In dangerous goods labeling, PSN refers to which term?

• A. Product Serial Number
• B. Parcel Shipping Number
• C. Proper Shipping Name
• D. Packaged Standard Name

Answer: (C)

The term PSN equals the Proper Shipping Name, the standardized name used to identify dangerous goods in transport. This name comes from the official Dangerous Goods List and is the identifier that appears on shipping papers and on labels to convey exactly what substance or article is being moved. Using the Proper Shipping Name ensures consistency across all parties, clarifying the material’s hazards and the corresponding packaging, handling, and emergency response requirements. It’s not a serial or tracking number, and it isn’t a general or trade name. It must match the entry in the regulatory list even if a product’s common name differs.
