Consumer commodity is a hazardous material that is packaged and distributed in a quantity and form intended or suitable for retail sale and designed for consumption by individuals for their personal care or household uses. This term can also include certain drugs or medicines. Not all hazardous material permitted to be shipped as a limited quantity can qualify as a consumer commodity. The consumer commodity category does not apply to materials, intended for air transportation, in hazard Classes 4, 5, and 8, and portions of hazard Class 9. It is the responsibility of the mailer to know the correct DOT hazard class of a hazardous material before mailing (see 323). The Consumer Commodity category is unique to the United States, and its use is prohibited with international shipments.
