Which organization regulates international air hazmat shipments?

• A. International Air Transport Association (IATA) Dangerous Goods Regulation (DGR)
• B. U.S. Department of Transportation Hazardous Materials Regulations (HMR)
• C. International Maritime Organization IMDG Code
• D. Occupational Safety and Health Administration HazCom

Answer: (A)

For international air hazmat shipments, the standard you use is the Dangerous Goods Regulations (DGR) published by the International Air Transport Association. This set of rules provides the globally recognized requirements for classifying, packaging, labeling, documenting, and training when dangerous goods are transported by air. Airlines and shippers rely on the DGR because it is harmonized with the ICAO Technical Instructions, ensuring consistency across countries and carriers.

The other options point to different systems: the US Department of Transportation Hazardous Materials Regulations mainly govern hazmat within the United States or international shipments under U.S. jurisdiction, not the global air standard itself; the International Maritime Organization’s IMDG Code covers maritime transport; OSHA HazCom relates to workplace chemical hazard communication.
