EPA to Host May 8 Webinar on TSCA CBI Claim Expirations

On May 6, 2026, at 4:00 p.m. EDT, EPA will host a webinar on expiring confidential business information (CBI) claims under the Toxic Substances Control Act (TSCA).

According to EPA, the webinar will help companies, stakeholders, and the public understand the regulatory requirements governing the lifecycle of CBI claims, including how to determine whether a claim is expiring and how to request an extension.  EPA will also demonstrate the Central Data Exchange (CDX) application that TSCA submitters must use to request extensions, address frequently asked questions, and outline effective ways to communicate with the agency about the CBI claim expiration process.

Registration is available here.

Last week, EPA released the first list of expiring CBI claims and announced the deployment of the CDX extension request tool in advance of the first expirations, which begin on June 22, 2026.  Additional details on the list of expiring claims and the CDX tool are available in a previous post.
