(1) Except for Class 7 (radioactive) materials described in accordance with paragraph (d) of this section, if the proper shipping name for a material that is a hazardous substance does not identify the hazardous substance by name, the name of the hazardous substance must be entered in parentheses in association with the basic description. If the material contains two or more hazardous substances, at least two hazardous substances, including the two with the lowest reportable quantities (RQs), must be identified. For a hazardous waste, the waste code (e.g., D001), if appropriate, may be used to identify the hazardous substance.
(2) The letters “RQ” must be entered on the shipping paper either before or after the basic description required by § 172.202 for each hazardous substance (see definition in § 171.8 of this subchapter). For example: “RQ, UN 1098, Allyl alcohol, 6.1, I, Toxic-inhalation hazard, Zone B”; or “UN 3077, Environmentally hazardous substances, solid, n.o.s., 9, III, RQ (Adipic acid)”.

The word “contains” may be used in association with the technical name, if appropriate. For organic peroxides which may qualify for more than one generic listing depending on concentration, the technical name must include the actual concentration being shipped or the concentration range for the appropriate generic listing. For example, “UN 3102, Organic peroxide type B, solid, 5.2, (dibenzoyl peroxide, 52-100%)” or “UN 3108, Organic peroxide type E, solid, 5.2, (dibenzoyl peroxide, paste, <52%)”.

(ii) To a material for which the hazard class is to be determined by testing under the criteria in § 172.101(c)(11).
(iii) If the n.o.s. description for the material (other than a mixture of hazardous materials of different classes meeting the definitions of more than one hazard class) contains the name of the chemical element or group which is primarily responsible for the material being included in the hazard class indicated.
(iv) If the n.o.s. description for the material (which is a mixture of hazardous materials of different classes meeting the definition of more than one hazard class) contains the name of the chemical element or group responsible for the material meeting the definition of one of these classes. In such cases, only the technical name of the component that is not appropriately identified in the n.o.s. description shall be entered in parentheses.
(l) Marine pollutants. (1) If the proper shipping name for a material which is a marine pollutant does not identify by name the component which makes the material a marine pollutant, the name of that component must appear in parentheses in association with the basic description.
