Latest Update to the U.S. TSCA Inventory

U.S. EPA updates its TSCA Chemical Substance Inventory, and plans the next update in summer 2023.

On February 16, 2023, the U.S. Environmental Protection Agency (EPA) released the most update-to-date version of the Toxic Substances Control Act (TSCA) Chemical Substance Inventory.

The TSCA Inventory is a list of all existing chemical substances manufactured, processed or imported in the U.S. It now contains 86,685 chemicals, of which 42,170 are active in U.S. commerce. The Inventory is available on EPA’s website

According to EPA, this update to the public TSCA Inventory is part of EPA’s biannual posting of non-confidential Inventory data. The next regular update of the TSCA Inventory is planned for summer 2023.

What’s changed?

Several hundred substances are now listed with their specific chemical identities after having been moved from the confidential portion of the Inventory to the public portion as part of EPA’s ongoing TSCA confidential business information (CBI) review efforts. Other updates to the Inventory include new commercial activity data, unique identifier data and regulatory flags (e.g., significant new use rules and test orders).

EPA reminds TSCA submitters to check EPA’s Central Data Exchange (CDX) site regularly for important correspondence from the EPA.
