EPA provides process update on expiring TSCA CBI claims beginning June 2026 and extension timing via CDX

EPA issued an implementation/process update explaining how it will notify submitters of expiring TSCA Confidential Business Information (CBI) claims (generally expiring 10 years after submission), noting that expirations for claims submitted shortly after the 2016 TSCA amendments will begin in June 2026. EPA emphasized that companies seeking to maintain CBI protection must submit extension requests via CDX with substantiation no later than 30 days prior to the expiration date. Compliance teams should review internal TSCA submission inventories and set controls to ensure timely CDX extension filings to avoid loss of CBI protections.
