The Toxic Substances Control Act (TSCA) is a United States law, passed by the United States Congress in 1976 and administered by the United States Environmental Protection Agency, that regulates the introduction of new or already existing chemicals. When the TSCA was put into place, all existing chemicals were considered to be safe for use and subsequently grandfathered in. Its three main objectives are to assess and regulate new commercial chemicals before they enter the market, to regulate chemicals already existing in 1976 that posed an "unreasonable risk to health or to the environment", as for example PCB's, lead, mercury and radon, and to regulate these chemicals' distribution and use.

Contrary to what the name implies, TSCA does not separate chemicals into categories of toxic and non-toxic. Rather it prohibits the manufacture or importation of chemicals that are not on the TSCA Inventory or subject to one of many exemptions. Chemicals listed on the TSCA inventory are referred to as "existing chemicals", while chemicals not listed are referred to as new chemicals. The TSCA defines the term "chemical substance" as "any organic or inorganic substance of a particular molecular identity, including any combination of these substances occurring in whole or in part as a result of a chemical reaction or occurring in nature, and any element or uncombined radical". Generally, manufacturers must submit premanufacturing notification to the U.S. Environmental Protection Agency (EPA) prior to manufacturing or importing new chemicals for commerce. Exceptions include one for substances used only in small quantities for research and development under Section 5(h)(3), for foods, food additives, drugs, cosmetics or devices regulated under the Federal Food, Drug, and Cosmetic Act, for pesticides regulated by the Federal Insecticide, Fungicide, and Rodenticide Act, for tobacco and tobacco products regulated by the Bureau of Alcohol, Tobacco, Firearms and Explosives, and for radioactive materials and wastes regulated by the Nuclear Regulatory Commission. The EPA reviews new chemical notifications and if it finds an "unreasonable risk to human health or the environment," it may regulate the substance from limiting uses or production volume to outright banning it. In 2013, the Frank R. Lautenberg Chemical Safety for the 21st Century Act was proposed as the first major overhaul in many years.
