What type of materials does Class 9 of DOT classifications refer to?

Class 9 of the DOT (Department of Transportation) classifications refers to miscellaneous hazardous materials that do not fit into the other specific hazard classes. This class encompasses a variety of materials that may pose a risk during transportation but are generally seen as less hazardous than those designated in the first eight classes. Examples of materials in this category include environmentally hazardous substances, dry ice, and materials that may not pose an immediate threat but still require special attention and regulations during transport. Understanding this classification is important for ensuring compliance with safety standards and for properly managing transportation risks associated with a broad range of substances.
