As a starting point, look up the product’s Safety Data Sheet (SDS). Most consumer products that come from reputable manufacturers will have a SDS that includes a transportation hazard classification for the product. This classification provides a four-digit ID number, a proper shipping name, the hazard class, and the packing group for the product. Use this information to identify the correct entry on the Hazardous Materials Table.

The Hazardous Materials Table contains references to the appropriate packaging sections, certain quantity limitations, and any special provisions or exceptions. The table also contains the label codes and basic description for the hazmat. Obtaining the correct hazard classification is the most important part of getting started with shipping hazmat. All other requirements, including packaging, marks, labels, and shipping paper requirements, will be based on the hazard classification of a product. The hazmat regulations provide classification criteria that manufacturers, shippers, and others can use to classify hazardous material. Certain types of hazmat require approval of the classification determination prior to shipment.
