What regulation serves as the primary source of information for the transport of hazmat within the United States?

• A. Title 49, Code of Federal Regulations (CFR)
• B. Department of Transportation Hazardous Materials Regulations (HMR)
• C. International Air Transport Association Dangerous Goods Regulation (IATA DGR)
• D. Occupational Safety and Health Administration Hazard Communication Standard (HazCom)

Answer: (A)

Understanding where hazmat transport rules live in U.S. law helps you know where to look for requirements. The Hazardous Materials Regulations define how hazmat must be packaged, labeled, shipped, and handled, and they are officially codified in Title 49 of the Code of Federal Regulations. Within that title, the key requirements appear in Parts 171 through 180, making Title 49 CFR the primary source for information on hazmat transport in the United States. The Hazardous Materials Regulations themselves are the rules, but their formal and most accessible home is Title 49 CFR. Other options refer to related but not primary sources: international air regulations like the IATA DGR apply to global air shipments, HazCom covers workplace chemical safety labeling, and while the HMR is the rule set, stating it within Title 49 CFR is why this is the best reference for U.S. hazmat transport.
