Hazardous materials shipping is governed by a combination of Department of Transportation (DOT) regulations and International Air Transport Association (IATA) guidelines. These regulations are designed to ensure the safe and secure transportation of dangerous goods by road and air, minimizing risks to people, property, and the environment. 

The United States Code of Federal Regulations (CFR) and IATA’s Dangerous Goods Regulations (DGR) compile the necessary standards for multimodal HAZMAT shipping.
