TSCA PFAS Reporting Deadline Delayed to January 2027: What Changed and What Didn't

On April 13, 2026, the EPA announced a third delay to the TSCA Section 8(a)(7) PFAS reporting deadline. The submission period, originally set to begin April 13, 2026, is now pushed to either January 31, 2027, or 60 days after EPA publishes a revised final rule—whichever comes first.

⚡ TL;DR: The deadline has moved again, but TSCA 8(a)(7) PFAS reporting is not going away. You must prepare now under the current broad scope, conduct a thorough “known or reasonably ascertainable” data search of 11 years of records, and assume you’re covered until proven otherwise.

For manufacturers and importers covered under TSCA 8(a)(7), this is the third deadline shift in three years. And if you’re waiting for the rule to disappear entirely, stop: it won’t. The statutory mandate cannot be waived. But what did change in this latest delay, and more importantly, what should you be doing right now?

⚠️ The Pain Point: Manufacturers are betting the exemptions will pass and reduce their obligations. The exemptions may not survive. They’re not final. Even if they do pass, waiting for finalization means you’ll have only 6 months to conduct 11 years of historical data searches across supply chains—an impossible timeline for companies with complex operations.

The Deadline Moved Again—Here’s What Actually Changed

This is not a cancellation. This is a delay triggered by a specific event: EPA’s still-pending revisions to the reporting rule itself.

The Federal Register notice published April 13, 2026, states the new submission period start date is “either 60 days following the effective date of EPA’s forthcoming final rule revising the PFAS reporting requirements, or January 31, 2027, whichever comes first.” The underlying reason is straightforward: EPA cited the need for additional software development time to complete the CDX (Central Data Exchange) reporting portal.

Here’s the timeline in context:

October 2023: Original rule finalized. Reporting window: November 2024–May 2025. 88 FR 70516
May 2025: First delay. New submission window: April 13–October 13, 2026.
April 2026: Second delay. New submission window: January 31, 2027 (backstop) or 60 days after final revised rule.

The rule itself—codified at 40 CFR Part 705—has not changed in scope. The requirements remain as written: anyone who manufactured (including imported) PFAS or PFAS-containing articles from 2011 through 2022 must report. But EPA is working on proposed modifications that could narrow this scope significantly.

Why “Delay” Does Not Mean “Won’t Happen”

Many manufacturers treat regulatory delays as signals the requirement is weakening. In this case, that’s a dangerous assumption.

TSCA Section 8(a)(7) is a statutory mandate. Congress, not EPA, required this data collection. EPA cannot repeal Congress’s directive—it can only delay the start date and modify the scope through the rulemaking process. The statutory authority is immovable.

40 CFR Part 705 requires manufacturers to report information for each PFAS substance they made or imported in any year from 2011 through 2022, including:

Chemical identity
Categories of use
Total volume manufactured (including imported)
Byproducts
Environmental and health effects information
Worker exposure data
Disposal methods

This is a one-time, backward-looking submission window—not annual reporting. But the scope is massive because “manufacture” under TSCA includes importation.

Who Is Actually Covered (The Wider Net Than You Might Think)

This is where most manufacturers discover they’re affected: TSCA defines “manufacture” to include import.

If your company imported any of the following since 2011, you are potentially covered:

Electronics and semiconductors — gaskets, coatings, circuit board materials
Automotive parts — seals, hoses, protective coatings, waterproofing materials
Textiles and apparel — water-resistant fabrics, non-stick coatings, stain guards
Food packaging and cookware — non-stick surfaces, grease barriers, water-resistant coatings
Construction materials — water-resistant insulation, protective coatings, sealants
Firefighting equipment — aqueous film-forming foams (AFFF), protective gear
Industrial materials — chrome plating chemicals, semiconductor manufacturing fluids, hydraulic additives, thermal system insulation (TSI)

Under the rule as currently written, you must report on any article containing any of the 1,462+ PFAS substances on EPA’s structural definition list—regardless of the concentration.

This is where the proposed exemptions become critical for many importers.

The Proposed Exemptions (Not Final Yet, But Game-Changing If Adopted)

In November 2025, EPA proposed significant modifications to the rule’s scope. Most coverage of this rule has focused on the two headline carve-outs — the imported-article elimination and the 0.1% threshold — because those affect the largest share of downstream importers. But EPA’s November 13, 2025 proposed amendments would narrow the rule’s scope across six categories, not two.

The six proposed exemptions:

0.1% de minimis threshold (by weight) — articles and mixtures containing PFAS below 0.1% by weight would be exempt from reporting obligations.
Imported articles — companies that only imported PFAS-containing articles (rather than manufacturing PFAS chemicals directly) would be exempt from the historical reporting.
Byproducts — PFAS generated as byproducts would be carved out.
Impurities — PFAS present as impurities would be carved out.
Research and development (R&D) — PFAS manufactured or imported for R&D purposes would be exempt.
Non-isolated intermediates — PFAS that exist only as non-isolated intermediates in a process would be exempt.

Together these six would remove a large portion of the downstream and low-concentration universe the current rule sweeps in.

But here’s the critical point: do not assume any exemption until it’s final. As of June 2026, the revised rule is still not final — EPA’s update page, last revised April 9, 2026, calls the revision “forthcoming” and says the agency “plans to issue a final rule later this year.” Until EPA publishes a final revised rule and it takes effect, all six categories remain reportable under the broad current scope, which is legally enforceable. Companies that scope their obligation around an exemption that does not finalize will be caught unprepared during the submission window.

A note for small importers: the November 2025 proposal also frames a later effective window for small businesses whose only reporting obligation is PFAS in imported articles — a date commonly cited as April 13, 2027. That later window only exists if the proposed rule is finalized in its current form; it is a planning scenario, not current relief, and it does not change the broad January 31, 2027 backstop that governs everyone else. “We only import it” is not an exemption — yet.

The January 2027 backstop deadline exists precisely because EPA knows the revised rule may not be finalized before then.

“Known or Reasonably Ascertainable” Data: The Standard That Trips Up Most Companies

The rule does not require new testing. But it does require a documented, comprehensive search of existing records using the “known or reasonably ascertainable” (KRA) standard.

According to EPA’s TSCA 8(a)(7) FAQs published November 2024, the KRA standard means companies must conduct a thorough, documented review of:

Purchase orders and invoices
Safety Data Sheets (SDS)
Supplier certifications
Import records and bills of lading
Manufacturing specifications
Product formulations
Environmental monitoring reports
Worker exposure assessments

“We didn’t know we had PFAS in that product” is not a legal defense. If a reasonable search would have found the information—in an SDS, supplier documentation, or import record—EPA expects you to have found it. The burden is on you to document that search.

For companies with complex, multi-year supply chains, this search takes time. If you wait until the submission window opens to begin assembling 11 years of records (2011–2022), six months will not be enough. Start the data search now.

Enforcement Teeth and EPA’s Compliance First Policy

TSCA 8(a)(7) enforcement has not begun because the submission period has not opened. But the penalty framework is established and substantial.

Under 15 U.S.C. § 2615 and 40 CFR 19.4 (2026 inflation adjustment, Federal Register 2026-00535), civil penalties for TSCA Section 8 violations can reach up to $25,000 or more per day per violation, subject to annual inflation adjustments. Criminal penalties exist for knowing or willful violations, including potential imprisonment.

Here’s the practical part: EPA’s current “Compliance First” enforcement posture (issued under the Pritzlaff memo in December 2025) offers a path to penalty mitigation. Companies that voluntarily self-audit, identify reporting gaps, and disclose those gaps through EPA’s eDisclosure system before EPA discovers violations can receive 100% penalty relief.

This creates a window of opportunity: companies that begin the KRA data search now and discover gaps or ambiguities can voluntarily correct them before the enforcement window opens. Waiting until the submission window to discover problems is not the same as voluntary disclosure, and it costs far more in penalties.

State-Level PFAS Requirements (Separate from TSCA)

TSCA Section 8(a)(7) is a purely federal requirement with no state delegation—all reporting flows through EPA via CDX. However, states in iSi’s service region have independent PFAS monitoring and remediation obligations that operate in parallel:

Texas: TCEQ is expanding PFAS monitoring in drinking water and groundwater, with proposed provisional health-based guidelines. Manufacturers with PFAS discharges face separate state-level scrutiny beyond federal TSCA reporting.
Kansas: KDHE has adopted EPA’s PFAS health advisories for drinking water. No independent state PFAS reporting mandate for manufacturers, but remediation obligations may arise from site investigations.
Oklahoma and Missouri: Both states follow federal PFAS guidance without independent manufacturing reporting mandates.

Federal TSCA 8(a)(7) standard applies uniformly across all states. State obligations focus on water quality and remediation rather than manufacturing use reporting.

What Manufacturers Need to Do Now (Not in January 2027)

The delay does not mean you have time to spare. Here’s what should happen before the submission window opens:

Immediately (next 30 days):

Determine coverage — Review your purchasing, manufacturing, and import records from 2011–2022. If you manufactured, imported, or processed PFAS or PFAS-containing articles, you are covered until you can demonstrate you are not.
Register for CDX access — Create an account with EPA’s Central Data Exchange system if you haven’t already. Portal access can take 2–4 weeks to activate. Waiting until January 2027 to start this process puts you at risk.
Identify your PFAS universe — Cross-reference purchase orders, import records, and SDS documents against EPA’s list of 1,462+ PFAS substances. Broad structural definitions mean many chemicals you may not recognize as “PFAS” will be caught by EPA’s definition.

Within 90 days:

Conduct the KRA data search — Compile a documented, comprehensive list of all PFAS-related raw materials, chemical purchases, imported articles, and manufacturing processes. The EPA’s reporting instructions (November 2024) require detailed documentation of what you searched and what you found. This is not a casual review—it’s a legal standard.
Organize data for submission — Prepare raw material volumes, use categories, and supplier information in the format CDX will require. EPA has published small entity compliance guidance that walks through the required data fields.
Monitor the revised rule — Subscribe to EPA’s TSCA 8(a)(7) update page for the final revised rule publication. If the article import exemption and 0.1% threshold are finalized before January 2027, you may be able to significantly scale back your data preparation. But do not assume the exemption—prepare under the current broader scope and adjust only after the rule is final.

Retention requirement: Under 40 CFR 705.30, all records supporting your submission must be retained for five years from the date of submission. This includes both the data submitted and the underlying documentation of your KRA search.

The Cost of Getting This Wrong (And How to Get Ahead)

A single willful OSHA violation costs up to $165,514. A single TSCA 8 reporting violation can cost $25,000+ per day. For a company that misses the deadline or submits false information, penalties accumulate quickly.

But the alternative—proactive compliance—is straightforward: start the data search now, document everything, and let EPA’s eDisclosure system work in your favor if issues are found.

Companies that begin preparation now under the current rule’s broad scope will be ahead regardless of how the proposed exemptions shake out. If the exemptions pass, you can streamline. If they don’t, you are ready.

What iSi Brings to TSCA 8(a)(7) Preparation

Environmental compliance obligations like TSCA 8(a)(7) reporting require two things: regulatory knowledge and operational knowledge of your supply chain and manufacturing history. Most manufacturers have deep operational knowledge but no in-house PFAS regulatory expertise. That’s where gaps form—and where enforcement finds them.

iSi’s compliance consulting includes supply chain audits, KRA data gathering, and readiness support for regulatory submissions like TSCA 8(a)(7). We help manufacturers document their PFAS universe, assess coverage under current rules and proposed exemptions, and prepare submission-ready data—so the regulatory burden doesn’t become an operational crisis.

If you want to run the compliance check yourself first, iSi’s Compliance Gap Checker is a free starting point to identify which regulations apply to your facility.

The Bottom Line: Prepare Now, Not in January

The delay does not buy you time. It buys OSHA software engineers time. For your facility, the clock is running on the data search. Six months to compile 11 years of purchase orders, import records, safety data sheets, and supplier certifications across a complex supply chain is inadequate. Start now. Assume you’re covered. Document everything.

The exemptions, if they arrive, will be a relief. But they won’t change the fact that preparation begins today.

💰 The Cost Calculation: Conducting a thorough KRA search now: $2,000–10,000 depending on supply chain complexity. Penalty mitigation through EPA’s voluntary disclosure system: potential 100% relief if you identify gaps and disclose them before enforcement. The alternative—discovery during enforcement: $25,000+ per violation, plus mandatory facility audits and permit reviews.
