EPA issued a proposed rule to update the incorporation by reference (IBR) of multiple voluntary consensus standards in 40 CFR Part 770 (TSCA Title VI—Formaldehyde Emission Standards for Composite Wood Products). EPA also proposes adding ISO 12460-2:2024(en) as an additional small-scale quality control chamber test method and making related conforming updates (e.g., scope/definitions). Compliance teams in composite wood products and downstream supply chains should review whether current QA/QC testing methods and referenced standards would need updating if the rule is finalized, and should consider submitting comments to the docket by the stated deadline (March 13, 2026).
EPA issued a proposed rule to amend the Formaldehyde Emission Standards for Composite Wood Products regulations under TSCA Title VI by adding a new quality control test method (ISO 12460-2:2024(en) small-scale chamber method) and making technical updates to incorporated voluntary consensus standards. Compliance teams in the composite wood products supply chain should review the proposed updates to referenced standards/test methods and submit comments within the stated comment period once published in the Federal Register.
EPA updated its TSCA New Chemicals Program statistics page with current counts of PMNs, SNUNs, and MCANs under review (as of Feb. 1, 2026). While not a rule change, the updated workload/case-status metrics can affect company expectations for review timing and resourcing for Section 5 submissions, including tracking potential delays in risk assessment and determination steps.
EPA posted a notice that the latest biannual TSCA Chemical Substance Inventory update has been released. The notice indicates updates to Inventory-related metadata (e.g., activity data/unique identifiers/regulatory flags) and continued movement of some substances from the confidential to the public portion as part of TSCA CBI review efforts. Compliance teams should refresh internal Inventory reference datasets used to confirm Inventory status and related flags when screening substances for U.S. manufacture/import.
EPA posted an updated “Now Available: Latest Update to the TSCA Inventory” notice indicating the latest biannual refresh of the public (non-confidential) TSCA Inventory dataset. The notice describes updates to items such as commercial activity information, unique identifiers, and regulatory flags (e.g., SNURs/test orders). Compliance teams should refresh internal inventory screening datasets and re-check regulatory flags for substances used/imported, particularly for downstream SNUR/test-order indicators.
EPA published a Federal Register notice compiling TSCA Section 5 New Chemicals Program "statements of findings" for October 2025, covering determinations for certain new chemicals or significant new uses. While not a new rulemaking, this notice is operationally relevant for compliance teams tracking EPA’s Section 5 outcomes, potential consent order patterns, and significant new use considerations tied to TSCA notifications (PMNs/SNUNs).
EPA released technical resources describing common/default values used in TSCA new chemical risk assessments (e.g., occupational exposure and environmental release assumptions). While not a binding rule, the defaults are operationally important for PMN/SNUN submitters because they can affect EPA’s exposure estimates and risk determinations and therefore the quality and predictability of submissions and any resulting risk management measures.
EPA published an official process/timeline update for confidential business information (CBI) claims under TSCA that will begin expiring starting June 2026 (generally 10 years after submission). EPA explains it will post (in early spring) a first public list of submissions with expiring CBI claims, and will send direct notices via EPA’s CDX system. Companies seeking to maintain confidentiality must submit extension requests electronically via CDX no later than 30 days before the specific claim expiration date, including substantiation. This is operationally significant for TSCA compliance teams managing CBI portfolios and ensuring timely substantiation/extension workflows.
EPA published a Federal Register notice and supporting EPA webpage describing the process for upcoming expirations of TSCA Confidential Business Information (CBI) claims beginning in June 2026. EPA indicates it will (1) post the first public list of TSCA submissions with CBI claims expiring starting in June 2026 (planned for early spring 2026) and (2) send direct notifications to affected submitters via CDX. To maintain protection, submitters must file an extension request via CDX with required substantiation no later than 30 days prior to the claim’s expiration date. EPA also states it is developing a new CDX tool to collect extension requests and expects it to be available before June 2026; if delayed, EPA will post an update on the TSCA CBI website. Compliance teams should inventory affected TSCA submissions, monitor EPA’s posted lists/notifications, and prepare substantiation packages to meet the 30‑day pre-expiration submission timing.
EPA announced (and published a Federal Register notice describing) the process it will use to notify submitters of upcoming TSCA confidential business information (CBI) claim expirations (generally 10 years after submission, under the 2016 TSCA amendments). EPA states the first expirations will begin in June 2026 and that it will post public lists of TSCA submissions with expiring claims (starting in spring 2026) and send direct notices via EPA’s Central Data Exchange (CDX). To maintain confidentiality, companies must submit an extension request through CDX with required substantiation no later than 30 days before the claim’s expiration date. Compliance teams should inventory TSCA submissions with CBI claims, ensure CDX access/roles are in place, and prepare substantiation workflows ahead of the spring 2026 public list postings.
EPA published an update and accompanying Federal Register notice describing how it will implement expiration and extension procedures for TSCA CBI claims. EPA stated it will post lists of submissions with expiring CBI claims (first list in early spring 2026) and notify submitters via CDX; companies seeking to extend CBI protection must submit extension requests through CDX no later than 30 days before the claim expiration date with required substantiation. If no timely extension request is received, EPA may no longer be required to safeguard the information. Compliance teams should inventory TSCA submissions with CBI claims approaching the 10-year expiration window and prepare substantiations and CDX processes to file extension requests on time.
EPA posted an updated biannual public (non-confidential) TSCA Chemical Substance Inventory update. While not a rule change, the Inventory refresh affects substance status screening (existing vs. new chemicals), and may change operational compliance signals via updated commercial activity data (active/inactive), unique identifier data, and regulatory flags (e.g., SNUR/test order indicators). Compliance teams should refresh internal substance lists, re-run regulatory flag screening, and note any identities moved from confidential to public portions of the Inventory as part of EPA’s ongoing CBI reviews.
EPA published an update describing how it will notify submitters about TSCA CBI claims that will begin expiring starting June 2026 and how to maintain protection. EPA indicates it will (1) post public lists of submissions with expiring claims beginning in early spring 2026, (2) send direct notices via EPA’s Central Data Exchange (CDX), and (3) require companies seeking to maintain protection to submit an extension request (with substantiation) via CDX no later than 30 days before the claim’s expiration date. This affects companies relying on TSCA CBI protections and requires internal tracking of claim expiration dates and preparation of substantiation packages for timely extension requests.
EPA issued a Federal Register notice compiling TSCA Section 5 statements of findings for certain new chemicals or significant new uses covering July 2025 through September 2025. This notice provides transparency on EPA determinations for PMNs/SNUNs/MCANs and can be used by compliance teams to monitor trends in EPA findings and potential consent order/SNUR patterns affecting future submissions.
EPA published an implementation/process update for Toxic Substances Control Act (TSCA) confidential business information (CBI) claims that will begin expiring starting June 2026 under TSCA §14(e). EPA indicates it will post public lists of TSCA submissions with expiring CBI claims (expected in early spring) and also send direct notifications via EPA’s Central Data Exchange (CDX). To maintain CBI protection, companies must submit an extension request electronically via CDX no later than 30 days before the claim expiration date and include substantiation. EPA also notes it is developing a new CDX tool to support extension requests ahead of the June 2026 expiration wave. Compliance teams should identify TSCA submissions with expiring claims (including via TSCA Inventory resources) and prepare substantiation and CDX workflows to avoid inadvertent public disclosure.
EPA published an implementation/process update describing how it will notify submitters about TSCA confidential business information (CBI) claims expiring starting June 2026 and how to request extensions. EPA indicates it will post lists of submissions with expiring claims (and send notices via CDX), and that extension requests must be submitted electronically via CDX no later than 30 days prior to the claim’s expiration, including substantiation. Compliance teams should inventory existing TSCA CBI claims, establish monitoring for EPA’s posted lists/notices, and prepare substantiated extension requests where ongoing confidentiality is needed.
EPA announced the release of a public list of TSCA Confidential Business Information (CBI) claims scheduled to expire (initially covering claims expiring June 22, 2026 through July 31, 2026) and stated the list will be refreshed monthly. EPA also described the process for maintaining confidentiality by submitting an extension request and substantiation electronically via CDX no later than 30 days before the claim expires, including use of a new “TSCA Section 14(e) CBI Claim Extension Request” tool. Compliance teams should inventory TSCA submissions with CBI claims, confirm responsible CDX accounts/contacts, and prepare substantiation packages ahead of claim expiration dates to avoid loss of confidential status.
EPA published an update describing how it will implement TSCA’s 10-year expiration of most confidential business information (CBI) claims and how submitters can request extensions. EPA states the first CBI claims will begin expiring in June 2026. EPA plans to post (in early spring 2026) a public list of TSCA submissions with CBI claims expiring starting June 2026 and to send direct notices via EPA’s Central Data Exchange (CDX). To maintain confidentiality, submitters must file an extension request via CDX no later than 30 days before the claim’s expiration date and provide substantiation. Compliance teams should identify TSCA submissions with CBI claims approaching the 10-year mark, prepare substantiation materials, and ensure CDX access/workflows are in place to meet the “30 days before expiration” timing described by EPA.
EPA published an implementation/process update describing how it will handle the first wave of TSCA CBI claim expirations beginning in June 2026 (reflecting TSCA’s 10-year sunset for many non-exempt CBI claims). EPA states it will (1) post lists (early spring) of TSCA submissions with CBI claims expiring starting June 2026 and (2) notify submitters via EPA’s Central Data Exchange (CDX). To maintain confidentiality, submitters must file CBI extension requests electronically via CDX no later than 30 days before the claim’s expiration and provide substantiation; otherwise EPA may disclose the information. EPA also indicates it is developing a new CDX tool for these extension requests and intends it to be ready before June 2026.
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.
