From which list are the proper shipping name and UN numbers drawn?

• A. The IATA DGR Dangerous Goods List
• B. The Emergency Response Guide
• C. The Do Not Ship List
• D. The International Air Cargo Code

Answer: (A)

The proper shipping name and UN numbers come from the Dangerous Goods List within the IATA Dangerous Goods Regulations. This list is the authoritative catalog that pairs each UN number with its corresponding proper shipping name (the official name used on documents and labels) and provides the hazard class, packing instructions, and any special requirements. The PSN identifies what the substance or article is in shipping terms, while the UN number is the global four-digit identifier that groups similar hazards together for consistent handling and regulatory compliance. This standardization across carriers and countries is what keeps air shipments clear, labeled correctly, and properly documented. Other resources serve different purposes: the Emergency Response Guide offers initial guidance for first responders in an incident, not classification for shipping; the other items listed aren’t the standard source for PSN and UN numbers in air transport.
