The U.S. Environmental Protection Agency (EPA) announced on August 31, 2021, the availability of the latest Toxic Substances Control Act (TSCA) Inventory. EPA states that the biannual update to the public TSCA Inventory is part of its regular posting of non-confidential TSCA Inventory data. EPA plans the next regular update of the Inventory for winter 2022. According to EPA, the Inventory contains 86,607 chemicals of which 41,953 are active in U.S commerce. Other updates to the TSCA Inventory include new chemical substance additions, commercial activity data and regulatory flags, such as polymer exemptions, TSCA Section 4 test orders, and TSCA Section 5 significant new use rules (SNUR). In April 2021, EPA released a list of 390 chemicals expected to lose their confidential status and move to the public portion of the Inventory. EPA states that it continues to work on final declassifications for these chemicals and plans to include them in the next public posting of the TSCA Inventory.
