The latest TSCA Inventory is now available on EPA’s website. 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 summer 2022.

The Inventory contains 86,631 chemicals of which 42,039 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).

On October 15, 2021, EPA announced a list of 377 specific chemical identities that were expected to lose their confidential status and move to the public portion of the Inventory. These 377 are listed in this public Inventory posting by their specific chemical identities.
