Which agency publishes the Dangerous Goods Regulations (DGR) for air shipments?

• A. IATA
• B. ICAO
• C. DOT
• D. USPS

Answer: (A)

The main idea here is identifying who publishes the standard for dangerous goods carried by air. IATA, the International Air Transport Association, publishes the Dangerous Goods Regulations manual. This manual provides the practical, day-to-day rules used by airlines, freight forwarders, and shippers for classifying, packaging, labeling, documenting, and training when shipping hazardous materials by air, and it’s updated annually.

ICAO, on the other hand, publishes the Technical Instructions for the Safe Transport of Dangerous Goods by Air, which are international standards adopted by states and often aligned with the IATA DGR. The DGR from IATA is the more widely used practical reference in global air shipments. The other two organizations, DOT and USPS, do not publish the DGR.
