EPA Releases List Of Expiring CBI Claims Under TSCA

The U.S. Environmental Protection Agency (EPA) announced on April 24, 2026, the release of a publicly accessible list of Confidential Business Information (CBI) claims scheduled to expire under the Toxic Substances Control Act (TSCA). EPA states that the list includes claims that will expire between June 22, 2026, and July 31, 2026. According to EPA, to maintain accuracy and provide timely updates, it will refresh the list on a monthly basis as claims continue to approach their expiration dates. EPA “strongly encourage[s]” companies to review the list carefully and verify whether any of their claims are included.

To request extension of an expiring CBI claim, companies must submit a request electronically via the Central Data Exchange (CDX) no later than 30 days prior to the expiration date of the claims. The request must include substantiation of the need to extend the period of CBI protection. EPA notes that it has deployed a new “TSCA Section 14(e) CBI Claim Extension Request”
