TSCA

The Toxic Substances Control Act (TSCA, often pronounced "taa-ska") is a United States law, passed by the United States Congress in 1976, that regulates the introduction of new or already existing chemicals. It grandfathered most existing chemicals, in contrast to the Registration, Evaluation and Authorization of Chemicals (REACH) legislation of the European Union. However, as explained below, the TSCA specifically regulates polychlorinated biphenyl (PCB) products.

P.L. 94-469 (October 11, 1976) authorizes the Environmental Protection Agency to regulate toxic substances (any chemical that may present a risk of unreasonable harm to man or the environment). By definition, however, the Act excludes from EPA regulation under TSCA certain substances, including pesticides (as defined by and regulated under the Federal Insecticide, Fungicide, and Rodenticide Act), tobacco or tobacco products, and any food or food additive (as defined by and regulated under the Poultry Products Inspection Act, the Federal Meat Inspection Act, the Egg Products Inspection Act, or the Federal Food, Drug, and Cosmetic Act).
