The US Environmental Protection Agency has announced a rolling public list of confidentiality claims under TSCA that are set to expire, prompting companies to review and renew their submissions before the June 2026 deadline to protect sensitive information.
The US Environmental Protection Agency has begun publishing a public list of confidential business information claims under the Toxic Substances Control Act that are due to lapse in the coming months, starting with 293 claims scheduled to expire between 22 June 2026 and 31 July 2026. EPA says the list will be refreshed each month as additional claims move towards their deadlines, and the agency is also sending direct notices through its Central Data Exchange reporting system. Companies are being urged to check whether any of their submissions are included, because once the deadline passes, protection may fall away and the underlying information can be disclosed.
The move marks the start of a rolling expiry process tied to the 2016 Lautenberg amendments to TSCA, which introduced a 10-year limit for most confidentiality claims. EPA has said that the first wave covers claims filed shortly after the statute was amended, and that the expiration timetable will continue to run through future submissions on a staggered basis. For chemical identity claims, the deadline is calculated from the first confidential submission for that substance after 22 June 2016, which means later filers may face shorter remaining protection than they expected.
EPA’s guidance says submitters will be notified at least 60 days before a claim expires, but companies still have only 30 days before the deadline to file a substantiated extension request in CDX. The request must explain why confidentiality should continue, and EPA says it will review each filing before the claim expires. The agency has also said companies should not assume that contact details from a decade ago remain valid, particularly if staff, offices or ownership have changed.
The practical challenge for industry is that many of the original filings were made years ago, often by personnel who have since left the business. EPA’s own materials warn that if a company does not act in time, the information may be made public without further notice. The agency has also indicated that some categories of information may be exempt from expiry or from substantiation requirements, including certain process details, customer and supplier identities, and some production-related data, so companies may need legal review to determine which claims genuinely require renewal.
The broader backdrop is a transparency push that EPA says is meant to balance public access with legitimate trade-secret protection. Industry lawyers have warned that the June 2026 start date could trigger a substantial volume of renewals, especially for companies with large TSCA inventories or complex legacy records. For regulated businesses, the message is straightforward: check the public list, verify CDX records, identify expiring claims early and prepare substantiated extensions well before the 30-day window closes.
