DOT Hazmat – Labeling
The packaging used to secure hazardous materials during transport typically contains markings and labels to indicate that it contains a hazardous material. The purpose of marking and labeling is to communicate the hazards and risks of the materials being transported to anyone who could potentially be exposed to them.“Labeling” refers to the placement of primary and, if applicable, subsidiary hazard labels on the outer package. DOT labeling requirements are contained in Part 172, Subpart E of the HMR.

Key Questions
What is the difference between the terms “packaging” and “package”?
“Packaging” refers to the container(s) and other materials used to contain hazardous materials, while “package” refers to the packaging and its contents (hazardous materials).
Why are hazardous material packages marked and labeled when they are shipped?
To communicate the hazards and risks of the materials being transported to anyone who could potentially be exposed to them.
Can international “dangerous goods” labels be used in place of DOT hazmat labels during transportation in the U.S.?
Labels required by several international organizations for shipments of Dangerous Goods (the international term for hazardous materials) may be used in place of or in addition to DOT hazmat labels.
For small packages, can hazmat labels be smaller than the requirements listed in the HMR?
The labels can be smaller but the symbol and other elements on the labels must remain “clearly visible.”
Why is there no text on some hazmat labels? Is this acceptable?
A text description of the hazard is optional (it is not required), except for Class 7 Radioactive materials. When text is included, it must meet the size requirements in the HMR.
Sample Video Transcript
The packaging used to secure hazardous materials during transport typically contains markings and labels to indicate that it contains a hazardous material. The purpose of marking and labeling is to communicate the hazards and risks of the materials being transported to anyone who could potentially be exposed to them. The term “marking” refers to the placement of required information on the outer package containing the hazardous material. This typically includes a Proper Shipping Name, identification number, a specification or UN POP mark, and any other required information, instructions, or cautions. “Labeling” refers to the placement of primary and, if applicable, subsidiary hazard labels on the outer package. DOT marking and labeling requirements are contained, respectively, in Subparts D and E in Part 172 of the HMR.
