U.S. chemical shipments
Chemical shipments must be regulated in order to ensure the safe transportation of potentially hazardous materials. In the United States, chemical shipments are regulated by the Department of Transportation, the International Air Transport Association, and the Environmental Protection Agency. Through the U.S. Department of Transportation, the Pipeline and Hazardous Materials Safety Administration regulates the movement of chemicals to industries and consumers through any mode of transportation. They have developed standards for classifying, handling, and packaging many shipments within the nation. Shipping chemicals internationally may often require specific regulations such as permits and is regulated by the International Air Transportation Association.
