WASHINGTON (August 31, 2021) – The latest TSCA Inventory is now available at: The TSCA Inventory is a list of all existing chemical substances manufactured, processed, or imported in the U.S.


This biannual update to the public TSCA Inventory is part of EPA’s regular posting of non-confidential TSCA Inventory data. The next regular update of the Inventory is planned for winter 2022.


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 (SNURs).


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 continues to work on finalizing the declassifications for these chemicals and plans to include them in the next public posting of the TSCA Inventory.
