On April 23, 2026, US EPA announced the release of a publicly accessible list of confidential business information (CBI) claims submitted by companies 10 years ago that are scheduled to expire under the Toxic Substances Control Act (TSCA). The list includes 293 CBI claims that will expire between June 22, 2026, and July 31, 2026. EPA will add to the list on a monthly basis as CBI claims continue to approach their expiration dates. In addition, EPA intends to directly notify the original submitter of each expiring CBI claim via the agency’s electronic document system, the Central Data Exchange (CDX). Companies that submitted TSCA CBI claims between the time when TSCA was amended on June 22, 2016, and July 31, 2026, should carefully review this list and monitor their CDX accounts, verify whether any of their CBI claims are included, and prepare to submit extension requests to maintain critical CBI protections. These extension requests must be made no later than 30 days prior to the expiration of the CBI claim. Companies who fail to renew expiring CBI claims risk losing protection from disclosure of their confidential information.
