TSCA Chemical Substance Inventory (Active-Inactive)
TSCA Chemical Substance Inventory (Active-Inactive)
Section 8 (b) of the Toxic Substances Control Act (TSCA) requires EPA to compile, keep current and publish a list of each chemical substance that is manufactured or processed, including imports, in the United States for uses under TSCA. Also called the “TSCA Inventory” or simply “the Inventory,” it plays a central role in the regulation of most industrial chemicals in the United States.
The Toxic Substances Control Act (TSCA), as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act, requires EPA to designate chemical substances on the TSCA Chemical Substance Inventory as either “active” or “inactive” in U.S. commerce. To accomplish that, EPA finalized a rule requiring industry reporting of chemicals manufactured (including imported) or processed in the U.S. over a 10 year period ending on June 21, 2016.
This reporting was completed on October 5, 2018, and was used to identify chemical substances on the TSCA Inventory as active or inactive in U.S. commerce. Starting August 5, 2019, manufacturers and processors are required to notify EPA before reintroducing inactive substances into U.S. commerce. Manufacturers and processors can notify EPA via a Notice of Activity Form B, found in EPA's Central Data Exchange (CDX). Upon receiving such notification, EPA will change the commercial activity designation of inactive substances to active.
