EPA published final Significant New Use Rules (SNURs) under TSCA Section 5 for a set of chemical substances (SNUR batch “26-2”). Companies that manufacture, import, or process any of the covered substances must evaluate whether their activities constitute a “significant new use” and, if so, submit a Significant New Use Notice (SNUN) before commencing that use. Compliance teams should identify whether any covered substances appear in products, intermediates, or R&D pipelines and update new-chemical/SNUR screening processes accordingly.
EPA published a proposed rule to establish Significant New Use Rules (SNURs) for certain chemical substances (SNUR batch 26-2). If finalized, manufacturers and processors would be required to submit a Significant New Use Notice (SNUN) at least 90 days before commencing any activity designated as a significant new use (generally, activities not consistent with protective measures in underlying TSCA §5 orders). Compliance teams should determine whether any portfolio substances or planned uses could be affected and consider submitting comments by the stated deadline.
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 finalized a change to the TSCA Section 8(a)(7) one-time PFAS reporting timeline by moving the start of the reporting submission period from a fixed date (previously April 13, 2026) to a trigger date: 60 days after the effective date of EPA’s forthcoming revision to the PFAS 8(a)(7) rule. This impacts entities that manufactured or imported PFAS (including PFAS in articles) during the covered period and need to plan reporting readiness around a rule-triggered start rather than a calendar date.
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/or hazard assessment materials for HHCB, phthalic anhydride, o-dichlorobenzene (o-DCB), and p-dichlorobenzene (p-DCB), and announced TSCA Science Advisory Committee on Chemicals (SACC) peer review meeting dates (including a preparatory meeting on May 26, 2026 and a peer review meeting on June 8–12, 2026). Stakeholders should review the drafts and participate in the SACC/public docket process because draft conclusions (e.g., preliminary unreasonable-risk findings for certain chemicals/uses described by EPA) may inform subsequent TSCA Section 6 risk management actions.
EPA released draft risk evaluation documents for HHCB (fragrance ingredient), phthalic anhydride, o-dichlorobenzene (oDCB), and p-dichlorobenzene (pDCB). The agency is convening a peer review meeting of the Science Advisory Committee on Chemicals (SACC) and soliciting public comments. HHCB draft finding shows no unreasonable risk across 22 conditions of use; phthalic anhydride shows unreasonable risk to workers in 36 conditions and consumers in 2 conditions from dermal/inhalation exposure.
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 announced/finalized a change to the start of the TSCA §8(a)(7) PFAS one-time reporting submission period. The prior start date of April 13, 2026 is replaced with a trigger tied to a forthcoming final rule revising the PFAS §8(a)(7) rule: the submission period will begin 60 days following the effective date of that forthcoming final rule, with a backstop start date of January 31, 2027 (whichever is earlier). Compliance teams responsible for TSCA PFAS reporting (entities that manufactured, including imported, PFAS during 2011–2022) should adjust project timelines to the new trigger while continuing data gathering because the underlying reporting obligation remains.
EPA announced/finalized a change to the start of the submission period for the TSCA Section 8(a)(7) one-time PFAS reporting rule. The update moves the start of the reporting period from April 13, 2026 to 60 days after the effective date of a forthcoming final rule revising the TSCA PFAS reporting rule (scope revisions). This affects entities that manufactured (including imported) PFAS during 2011–2022 and changes internal compliance project timelines (data collection, supplier outreach, and submission readiness).
EPA finalized a change to the TSCA §8(a)(7) PFAS reporting timeline: the start of the submission period is no longer a fixed April 13, 2026 date. Instead, the reporting window will begin 60 days after the effective date of a forthcoming final rule revising the PFAS reporting regulation, with a backstop start date of January 31, 2027 (whichever is earlier, as described in the signed pre-publication final rule). This affects entities that manufactured (including imported) PFAS during the 2011–2022 lookback period (including certain article importers), requiring compliance teams to re-baseline project plans for data collection, supplier outreach, and internal system readiness against the new trigger-based start date.
EPA finalized a change to the start of the submission period for the TSCA §8(a)(7) PFAS Reporting and Recordkeeping Rule (40 CFR Part 705). Instead of a fixed start date, the submission period will begin 60 days after the effective date of a forthcoming final rule that revises the substantive requirements, or on January 31, 2027, whichever is earlier. This directly affects compliance planning, internal calendars, and resourcing for entities that manufactured (including imported) PFAS during the covered period.
EPA finalized an update to the TSCA Section 8(a)(7) one-time PFAS reporting rule changing when the submission period starts. Instead of beginning April 13, 2026, the start is moved to a date tied to a forthcoming final rule revising the PFAS reporting regulation (start is triggered 60 days after that revision’s effective date). This affects compliance planning for entities that manufactured (including imported) PFAS during 2011–2022, including preparation of data systems, supplier outreach, and internal record collection timelines.
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 published documentation describing common assumptions (including default values) used in assessing new chemicals under TSCA, intended to increase transparency and improve the efficiency of the new chemicals review process. For PMN/SNUN submitters, this is actionable for aligning submissions with EPA’s stated assumptions to reduce follow-up information requests and better anticipate EPA’s exposure and hazard assessment approaches.
EPA proposed to extend the reporting deadline by one year to May 21, 2027 for the one-time TSCA Section 8(d) Health and Safety Data Reporting Rule submissions. If finalized, manufacturers (including importers) and processors subject to the rule would have additional time to compile and submit required unpublished health and safety studies and related information to EPA, affecting internal data-collection, legal review, and submission timelines.
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.
The EPA has extended the submission deadline for the TSCA Section 8(d) Health and Safety Data Reporting rule from May 22, 2026 to May 21, 2027. This extension applies to manufacturers (including importers) of the 16 chemical substances specified in 40 CFR 716.120. The extension provides additional time for businesses to prepare submissions while EPA considers revisions to the underlying rule.
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 proposes extending certain Workplace Chemical Protection Program compliance dates for perchloroethylene (PCE) and carbon tetrachloride (CTC) TSCA rules. The extension aligns non-federal entity compliance dates with federal agency deadlines. The proposed timeline adjustment does not weaken existing protections or change the ultimate level of protection required. EPA intends to publish proposed rules amending various aspects in summer 2026.
