Material Not Specifically Listed

If a material is not specifically listed in Table A4.1, then determine the PSN by comparing the characteristics of that material with the definitions of the various hazard classes in this manual. Assign a "Not Otherwise Specified" (N.O.S.) name based on the material's hazard class. Examples: "FLAMMABLE LIQUID, N.O.S.", "CORROSIVE SOLID, N.O.S.".

Attachment 1 contains hazard class definitions. Determine the appropriate technical name according to A4.5.2.

For a material that the hazard class must be determined by testing, or a material that is a hazardous waste, you may assign a tentative shipping name based on:

• The defining criteria of the hazard class
• The hazard precedence prescribed in A4.2.4
• The shipper's knowledge of the material
• A3.3.1.4 for new explosives

If a N.O.S. PSN is assigned, a technical name is not required.
