What is the classification of miscellaneous materials in HAZMAT?

Miscellaneous materials in the Hazardous Materials (HAZMAT) classification are categorized as Class 9. This classification includes materials that present a hazard during transportation, but do not fall into the other specified hazard classes. Class 9 encompasses a variety of different substances that may not otherwise be classified, such as certain hazardous wastes, environmentally hazardous substances, or materials that pose a risk but are not defined by the distinct characteristics of other classes.

The use of Class 9 helps ensure that these materials are transported with the appropriate level of caution and awareness, even though they may not pose the same risks as those in the more commonly encountered classes such as Class 1 (explosives) or Class 6 (toxic substances). Understanding this classification is vital for proper handling, transport, and response to incidents involving these materials.
