Specifically, you ask that if a material contains a material that does not\ncontribute to the primary or subsidiary hazard class of the material, does it need to be included in\nthe determination of the proper shipping name.\nIf a material, that in certain concentrations meets the definition of a hazardous material, is being\nshipped in a concentration that the mixture no longer meets the hazard class associated with the\nmaterial, the material is not a hazardous material for purposes of the Hazardous Materials\nRegulations (HMR; 49 CFR Parts 171-180). Section 172.101(c)(10)(i) states that a mixture or\nsolution not identified specifically by name, comprised of a hazardous material identified in the\nHazardous Materials Table (HMT) by technical name and non-hazardous material, shall be\ndescribed using the proper shipping name of the hazardous material and the qualifying word\nidentified by technical name in the HMT and a non-hazardous material that does not contribute to\n\"mixture\" or solution, as appropriate, Therefore, a mixture comprised of a hazardous material\nthe hazardous material.\nthe primary or subsidiary hazard class of the material shall be described by the technical name of\nI hope this satisfies your inquiry.\nSincerely,\nEdward T.
