EPA’s TSCA Section 8(a)(7) PFAS reporting and recordkeeping webpage reiterates the reporting window for covered manufacturers (including importers) and the separate deadline for small manufacturers that only report as PFAS article importers. Compliance teams should use these dates to finalize internal data collection, supplier outreach, and CDX submission planning for the one-time PFAS reporting rule.
EPA updated its New Chemicals Program page providing publicly available versions of TSCA Section 5 orders addressing significant new uses for certain chemical substances, including PFAS (with confidential business information removed). Compliance teams should use the posted order text to understand the restrictions/conditions tied to these chemicals and ensure that any manufacturing, importing, processing, or use changes are evaluated against Section 5 order obligations and potential SNUN triggers.
EPA refreshed its public statistics for the TSCA New Chemicals Program (Section 5 submissions such as PMNs/SNUNs/MCANs and exemptions), providing updated counts and workload metrics. This is a transparency/program information update rather than a binding rule change, but it may affect compliance planning by indicating review timelines and backlogs.
EPA updated the TSCA New Chemicals Division Reference Library (Section 5 program support) to include additional technical memoranda/guidance used in new chemical risk assessments and decision-making. These materials can affect PMN/SNUN strategy and supporting data expectations (e.g., approaches for assessing environmental hazards of cathode active material new chemical substances and guidance on exposure assumptions/industrial hygiene considerations, plus a decision framework for skin irritation/corrosion hazard identification). Compliance teams submitting or planning TSCA Section 5 notices should review these documents because they may influence EPA’s hazard/exposure assumptions and resulting determinations or required risk management conditions.
EPA announced a proposed rule to revise procedures for conducting TSCA risk evaluations for existing chemicals (the TSCA risk evaluation 'framework rule'). The proposal would change key elements of the risk evaluation process (e.g., how unreasonable risk determinations are made across conditions of use and how certain exposure controls/parameters are handled). Stakeholders should track Federal Register publication and consider submitting comments during the stated comment period once open.
EPA further postponed until May 18, 2026, the conditions imposed on each of the TSCA section 6(g) exemptions as described in the final rule published December 17, 2024. This extension affects the trichloroethylene (TCE) risk management rule exemptions, providing additional time for compliance with exemption conditions.
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 issued a final action extending the postponement (an additional 90 days) of the effectiveness of certain provisions of the TSCA Section 6 trichloroethylene (TCE) risk management rule, specifically affecting conditions imposed on uses with TSCA §6(g) exemptions. The postponement extends the effectiveness date of the affected provisions until May 18, 2026. Compliance teams relying on §6(g) exemptions should reassess timing for meeting any conditions associated with exempted uses and track subsequent EPA actions in the same rulemaking docket.
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 proposed amendments to the TSCA Title VI Formaldehyde Emission Standards for Composite Wood Products. The proposal would add ISO 12460-2:2024(en) (small-scale chamber method) as an additional quality control test method for measuring formaldehyde emissions and update incorporation-by-reference to current versions of voluntary consensus standards. Compliance teams for composite wood product manufacturers, importers, fabricators, certifiers, and third-party labs should review the proposed test-method/standard updates and submit comments by the stated deadline, as adoption would affect testing, certification, and documentation practices under TSCA Title VI.
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 released a proposed rule under TSCA Title VI (Formaldehyde Emission Standards for Composite Wood Products) to add a new quality control (QC) test method (including ISO 12460-2:2024(en) as referenced in the EPA materials) and make technical updates to incorporated voluntary consensus standards. The proposal is open for public comment via docket EPA-HQ-OPPT-2017-0245. Compliance teams in composite wood products and downstream product supply chains should track potential changes to acceptable QC testing methods and referenced standards used for demonstrating conformity.
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 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 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 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 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 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 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.
