The U.S. Environmental Protection Agency (EPA) has announced the Toxic Substances Control Act (TSCA) Inventory update. This biannual update, made public by the EPA, is part of its routine dissemination of non-confidential TSCA Inventory data. The update aligns with the commencement of the 2024 Chemical Data Reporting (CDR) cycle submission period starting June 1, 2024.

Importance for Manufacturers and Importers

EPA advises manufacturers, including importers, to consult the latest TSCA Inventory to determine which chemicals to report under the CDR rule. EPA anticipates the next regular update of the TSCA Inventory will occur in early 2025.

Inventory Highlights

According to EPA, the TSCA Inventory now comprises 86,770 chemicals, with 42,377 actively used in U.S. commerce. Updates also include revisions to commercial activity data and regulatory flags, such as Significant New Use Rules (SNURs). EPA continues its efforts to disclose specific chemical identities by transitioning substances from the confidential to the public portion of the TSCA Inventory through ongoing TSCA confidential business information (CBI) review endeavors. Since the previous update in February 2024, approximately 133 chemicals have been moved from the confidential to the public portion.
