This topic covers the labeling requirements for hazardous materials developed by the U.S. Department of Transportation (DOT), which apply to a list of substances that have been determined to pose a significant risk to health, safety, and property when transported in commerce by air, highway, rail, or water.

The HazMat label regulations include specifications for labels, placards, and markings that must be prominently displayed on each shipping container or package, and on each transport vehicle that contains regulated hazardous chemicals.
