EPA issued a proposed rule to add Significant New Use Rules (SNURs) for certain chemical substances subject to TSCA consent orders. The proposal would require companies to submit a Significant New Use Notice (SNUN) at least 90 days before manufacturing or processing for a designated significant new use. Compliance teams should identify whether any affected substances are in their portfolios and consider commenting by the deadline; if finalized, SNUN planning/lead times and use restrictions may affect R&D, scale-up, importing, and downstream customer applications.
EPA finalized a rule modifying the start of the submission period for TSCA §8(a)(7) PFAS reporting (40 CFR part 705). The submission period will begin on January 31, 2027, or 60 days after the effective date of a forthcoming final rule that will make substantive revisions to the PFAS reporting rule—whichever is earlier. This changes the prior planned April 13, 2026 start and affects entities that manufactured or imported PFAS during the covered lookback period by shifting compliance planning to the new trigger/backstop dates and requiring monitoring of the forthcoming final revision that starts the 60-day clock.
EPA published draft TSCA risk evaluation documents for HHCB and phthalic anhydride and draft hazard assessment/supporting materials for o-dichlorobenzene and p-dichlorobenzene, and announced a Science Advisory Committee on Chemicals (SACC) peer review meeting scheduled for June 8–12, 2026 (with a preparatory meeting on May 26, 2026). EPA highlighted that the draft risk evaluation for phthalic anhydride identifies unreasonable risks for certain worker and consumer exposures, which could drive later TSCA Section 6 risk management if finalized. Compliance teams should review draft findings, prepare public comments for the peer review docket, and anticipate potential downstream risk management actions for affected conditions of use.
EPA released draft TSCA risk evaluation and hazard assessment materials for four chemicals (HHCB, phthalic anhydride, o-dichlorobenzene, and p-dichlorobenzene) and announced the Science Advisory Committee on Chemicals (SACC) peer review process, which includes opportunities for public input. While drafts are not binding final determinations, they can materially influence final risk evaluations and potential downstream TSCA §6 risk management actions; compliance teams should review draft findings relevant to their uses and consider participating in the peer review/comment process.
EPA’s TSCA Section 8(a)(7) PFAS reporting program page reiterates the one-time reporting submission window for most entities (Apr 13, 2026 through Oct 13, 2026) and the extended deadline for certain small manufacturers reporting solely as PFAS article importers (until Apr 13, 2027). Compliance teams should use the posted window to finalize internal data collection for PFAS manufactured/imported during the rule’s covered period, confirm eligibility for any extended deadline category, and ensure recordkeeping processes align with EPA’s stated requirements.
EPA proposed to extend the reporting deadline for the TSCA Section 8(d) Health and Safety Data Reporting rule covering 16 chemical substances. Compliance teams responsible for submitting unpublished health and safety studies and related information under TSCA 8(d) should review the proposed extension and adjust internal data-collection and submission timelines accordingly.
EPA announced a proposal to extend certain compliance dates in the final TSCA Section 6 risk management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC) to improve practical implementation (including Workplace Chemical Protection Program-related timelines). Until any amendments are finalized, currently-effective compliance dates remain in effect. EPA is seeking public comment via docket EPA-HQ-OPPT-2026-0992 on Regulations.gov.
EPA announced a proposal to extend certain compliance dates in the final TSCA §6 risk management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC), stating it is working on revisions intended to make the rules more practical and implementable. Until EPA completes rulemaking, existing compliance dates remain in effect. Compliance teams should monitor the Federal Register publication and the associated comment process once opened.
EPA released a proposal to extend certain compliance dates in the final TSCA Section 6 risk management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC) while EPA works on further rule revisions. EPA states it is not revisiting the underlying TSCA unreasonable risk determinations and that protections are not being weakened. EPA indicates a 30-day public comment period will run upon Federal Register publication and points stakeholders to the rulemaking docket via Regulations.gov, which compliance teams should monitor for the Federal Register notice, specific extended dates, and applicability details.
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 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 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 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 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 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.
