EPA published a Federal Register rule extending the postponement of effectiveness for certain provisions related to conditions imposed on TSCA §6(g) exemptions in the 2024 TSCA trichloroethylene (TCE) risk management rule. The postponement was extended so that, as of Feb. 17, 2026, the affected provisions are postponed until May 18, 2026. Companies relying on, seeking, or operating under TSCA §6(g) exemptions associated with the TCE rule should adjust compliance planning to the updated timeline and monitor for subsequent changes.
EPA published a final action extending the postponement of effectiveness for certain provisions of the TSCA risk management rule for trichloroethylene (TCE), specifically affecting conditions tied to TSCA section 6(g) exemptions, until May 18, 2026. This changes the timeline for when affected requirements become effective for entities relying on (or managing) exempted uses under the TCE rule. Compliance teams should reassess implementation schedules, contractual obligations, and operational controls tied to the postponed provisions.
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 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 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 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 posted an update stating it intends to reconsider the December 13, 2024 final TSCA Section 8(d) rule requiring manufacturers/importers of 16 chemicals to submit unpublished health and safety studies. EPA indicates reconsideration topics may include additional exemptions, a reporting threshold, and changes to the lookback period, and notes it anticipates appropriate action regarding the reporting deadline currently identified as May 22, 2026. Compliance teams subject to the 8(d) rule should monitor for subsequent rulemaking that could alter applicability or timing and should plan around the currently stated deadline until changes are finalized.
EPA signed and announced a proposed rule to amend the TSCA §8(a)(7) PFAS data reporting and recordkeeping requirements (40 CFR Part 705). The proposal would add several exemptions (including imported articles and a de minimis 0.1% concept) and make other practical/technical changes intended to reduce burden while maintaining access to safety data. Compliance teams subject to PFAS reporting should assess whether their operations would fall in/out of scope if finalized and consider submitting comments through the rulemaking docket during the comment period described by EPA (stated as 45 days after Federal Register publication in the research text).
EPA finalized a batch of Significant New Use Rules (SNURs) under TSCA Section 5, establishing significant new uses that trigger Significant New Use Notice (SNUN) obligations before manufacture, import, or processing for those uses can begin. This is a binding regulatory change for entities handling covered substances, requiring screening of uses against the SNUR conditions and updating internal new-use change-management to ensure SNUN submissions occur before initiating any designated significant new use. The research notes the final SNUR batch was published Nov. 4, 2025 and became effective Jan. 5, 2026.
EPA proposed multiple SNUR batches (published Nov. 3, 2025) and proposed amendments to existing SNURs (published Oct. 28, 2025). If finalized, these proposals would impose or modify TSCA Section 5 Significant New Use Notice (SNUN) requirements for specified chemical substances/uses. Compliance teams should monitor the relevant dockets, evaluate whether their substances/uses could be affected, and consider submitting comments as appropriate.
EPA issued a proposed rule to amend procedures for conducting chemical risk evaluations for existing chemicals under TSCA. This proposal would revise the risk evaluation framework and could affect how companies plan for risk evaluation scope, data submissions, use categorization, and downstream risk management implications. Compliance teams should review the proposal and consider participating in the public comment process for impacts to ongoing and future TSCA risk evaluations.
EPA announced availability of the latest update to the public (non-confidential) TSCA Inventory as part of its biannual posting cycle, including updates to inventory totals and associated data elements (e.g., commercial activity, unique identifier data, regulatory flags). EPA also notes the next regular update is planned for winter 2026. Compliance teams should refresh internal inventory reference datasets and re-check substance listing status and applicable flags used to support TSCA Inventory determinations.
EPA’s TSCA §8(a)(7) PFAS reporting program page describes the current reporting window and extended submission deadlines established via an interim final rule. Per the research text, submissions are due by Oct 13, 2026 for most manufacturers (including importers), and by Apr 13, 2027 for small manufacturers that only need to report PFAS in imported articles. Companies in scope should align data collection and internal reporting systems to the updated reporting window and submission deadlines and monitor ongoing rulemaking that could further alter scope.
