Press release submitted on behalf of RadTech.
EPA has released a publicly accessible list of Confidential Business Information (CBI) claims scheduled to expire under the Toxic Substances Control Act (TSCA). The initial list covers claims expiring between June 22, 2026, and July 31, 2026, and EPA plans to refresh the list monthly as additional claims approach expiration.
This may be important for companies that have submitted information to the EPA under TSCA and have claimed certain information, including chemical identities and other business-sensitive information, as confidential. Under TSCA section 14(e), most CBI claims expire after 10 years unless the submitter requests and EPA approves an extension. Without an approved extension, EPA may make the information public without further notice.
Members are encouraged to take the following steps:
- Review the EPA’s list of expiring claims
EPA has posted spreadsheets showing submissions, chemical identities, and companies associated with expiring claims. Members should review these lists to determine whether any of their company’s claims are included.
EPA page: https://www.epa.gov/tsca-cbi/cbi-claim-expiration
- Check the TSCA Inventory for chemical identity claims
For CBI claims related to specific chemical identities, EPA notes that companies can consult the TSCA Inventory and review the “EXP” column for expiration dates.

- Confirm CDX access and company contacts
EPA will attempt to send direct notice through the Central Data Exchange (CDX). Companies should ensure their CDX accounts, company contacts, authorized officials, technical contacts, and passphrases are up to date. Companies with lapsed or inaccessible CDX accounts should contact the CDX Help Desk as soon as possible.
CDX: https://cdx.epa.gov
Help Desk: helpdesk@epacdx.net
- Submit an extension request, if needed
Companies that want to extend an expiring CBI claim must submit a “TSCA Section 14(e) CBI Claim Extension Request” through CDX no later than 30 days before the claim expiration date. The request must include substantiation supporting the need for continued confidential treatment.
EPA has also posted a webinar recording and slides explaining the CBI claim expiration process and how to request an extension. These resources are available on the EPA’s CBI Claim Expiration page: https://www.epa.gov/tsca-cbi/cbi-claim-expiration
Questions about the extension process may be directed to the EPA at: TSCA_CBI_Expiration@epa.gov
RadTech encourages members with prior TSCA submissions or confidential chemical identity claims to review EPA’s materials promptly and consult appropriate regulatory or legal counsel as needed.
