the word "WASTE" must precede the proper shipping name in the transport document and package markings; and
the requirements of 49 CFR 172.205, with respect to the hazardous waste manifest apply.
For hazardous wastes that do not meet any other definition of dangerous goods according to these Technical Instructions:
the hazardous wastes shall be shipped under the basic dangerous goods description "UN 3082, WASTE ENVIRONMENTALLY HAZARDOUS SUBSTANCE, LIQUID, N.O.S., Class 9, III" or "UN 3077, WASTE ENVIRONMENTALLY HAZARDOUS SUBSTANCE, SOLID, N.O.S., Class 9, III", as appropriate, and in accordance with the requirements of these Technical Instructions applying to the shipment of goods under this description;
the package must meet all applicable General Packing Requirements of Part 4, Chapter 1 that would apply to dangerous goods of Packing Group III;
the requirements of 49 CFR 172.205 with respect to the hazardous waste manifest apply; and
