EPA releases list of expiring TSCA CBI claims and launches CDX process for CBI claim extension requests

EPA published a rolling public list of TSCA Confidential Business Information (CBI) claims scheduled to expire (including claims expiring between June 22, 2026 and July 31, 2026) and stated it will refresh the list monthly. EPA also described a new electronic extension-request process in EPA’s Central Data Exchange (CDX) using a dedicated tool (TSCA Section 14(e) CBI Claim Extension Request). Companies must submit extension requests with substantiation no later than 30 days before claim expiration to maintain confidentiality protections; otherwise, EPA may no longer be required to protect the information from disclosure. Compliance teams should inventory TSCA submissions with CBI claims, monitor the monthly expiring-claims list, and prepare CDX extension filings within EPA’s stated timing window.
