As of April 13, 2026, the EPA’s PFAS reporting window under TSCA Section 8(a)(7) is open. Every chemical manufacturer that produced or imported any PFAS between 2011 and 2022 now has until October 13, 2026 to submit complete, substance-level data to the EPA.
Six months sounds workable. It is not, for most operations. EPA’s own Regulatory Impact Analysis estimates 11.6 million compliance hours industry-wide. For mid-to-large manufacturers with multi-site operations, complex supplier networks, and legacy ERP data, the realistic preparation timeline runs 6 to 18 months.
This guide explains exactly what TSCA Section 8(a)(7) requires of manufacturers, where operations typically run into trouble, and what a compliant submission actually looks like from a data perspective.
Does My Manufacturing Company Need to Report PFAS to the EPA?
Yes, if your company manufactured or imported any PFAS in any form between January 1, 2011 and December 31, 2022. The obligation is broader than most manufacturers initially assume.
The rule covers intentional PFAS production, but it also covers PFAS that appeared as byproducts, trace impurities, or processing aids in your products or operations. If PFAS were present in your supply chain and entered your manufacturing process in any form, the reporting obligation applies.
Which industries are most commonly in scope?
- Fluoropolymer and specialty chemical production
- Semiconductor and electronics component manufacturing
- Coatings, adhesives and surface treatment products
- Firefighting foam (AFFF) and industrial foam formulation
- Textile, apparel and fabric treatment manufacturing
- Medical devices and pharmaceutical production
- Food packaging and paper product manufacturing
The Small Manufacturer Exemption: Narrower Than You Think
Companies that qualify as small manufacturers, generally those with under $12 million in annual sales and fewer than 100 employees, have an extended deadline of April 13, 2027.
If your operation does not meet both criteria, your deadline is October 13, 2026. Mid-sized manufacturers frequently assume they qualify for the extension and discover too late that they do not.

What Does TSCA Section 8(a)(7) Actually Require Manufacturers to Report?
This is the first federal mandate requiring comprehensive, substance-level PFAS reporting across an entire organization’s history. The data requirements are more granular than any previous chemical disclosure rule.
Manufacturers must submit the following for each reportable PFAS:
- Chemical identity: CAS number, IUPAC name, or structural formula for each substance
- Annual production and import volumes: for each year from 2011 through 2022, by substance
- Industrial and consumer use classifications: how each substance was used in your operations or products
- Site-level manufacturing and processing data: reported per facility, not just company-wide
- Byproduct and impurity disclosures: including unintentional PFAS generation during production
- Worker exposure data: occupational exposure estimates by substance and site
- Environmental release estimates: releases to air, water and land by substance and site
Understanding the ‘Known or Reasonably Ascertainable’ Standard
The EPA does not require manufacturers to have perfect records going back to 2011. However, it does require a documented, good-faith effort to locate data.
This standard becomes operationally significant in three Style situations:
- Pre-2015 records were lost during an ERP migration
- A supplier will not confirm whether a material contains trace PFAS
- A facility was acquired mid-period and prior records are incomplete
In all three cases, manufacturers are still expected to report what is reasonably ascertainable and document the effort behind any gaps. The burden of demonstrating that effort sits with the manufacturer, not with EPA.
How Large Is the PFAS Reporting Compliance Challenge?
EPA’s Regulatory Impact Analysis for this rule sets out the scale clearly. These are the figures every manufacturing leadership team should have in front of them.
| Metric | Figure |
|---|---|
| PFAS substances in reporting scope | 1,462+ |
| Companies expected to report | 131,000+ |
| Industry-wide compliance hours (EPA estimate) | 11.6 million hours |
| Total industry cost burden (EPA estimate) | $843 million |
| Maximum civil penalty per violation | $37,500 per day |
| Reporting window opens | April 13, 2026 |
| Deadline (standard manufacturers) | October 13, 2026 |
| Deadline (qualifying small manufacturers) | April 13, 2027 |
The 11.6 million industry-wide hours figure is the one that matters for operational planning. Spread across 131,000 companies, that averages roughly 88 hours per company. Mid-to-large manufacturers with complex product portfolios and multi-site operations are carrying a significantly larger share of that burden. Industry compliance professionals widely report actual preparation timelines of 6 to 18 months for companies of that profile.
Why Are Manufacturers Struggling With PFAS Reporting Compliance?
Most manufacturers are not behind because they lack intent. They are behind because TSCA Section 8(a)(7) requires a type of structured, cross-system, substance-level dataset that manufacturing operations have never needed to assemble in one place before.
The four data problems that create the most compliance risk:
- Fragmented source systems. Chemical identity data lives across SDS libraries, ERP platforms, QA systems, procurement records and supplier documentation. None of these systems were designed to talk to each other at the substance level, and none are formatted for EPA reporting schema.
- Non-standardized chemical naming. The same PFAS compound may appear under different CAS numbers, trade names, synonyms or abbreviations across different systems, sites and supplier relationships. EPA requires substance-level precision. Resolving those inconsistencies manually, across 14 years of records, is the single most time-consuming part of the process.
- Incomplete historical records. Reporting covers 2011 through 2022. Many manufacturers changed ERP systems, restructured facilities or changed suppliers during that window. Records from before 2016 are often unstructured, archived in formats that are difficult to search, or simply missing.
- Supplier opacity on trace PFAS. PFAS frequently appear as coatings, processing aids or trace impurities in purchased raw materials. Many supplier SDS documents do not disclose PFAS below a certain threshold. Manufacturers are still expected to report these substances if the ‘reasonably ascertainable’ standard can be met through supplier outreach or alternative documentation.
The result is that a compliance team working with spreadsheets and manual document review is not sized for this problem. The data complexity requires automated extraction, cross-system reconciliation and structured supplier workflows, none of which traditional EHS software was built to provide.
How AI Specifically Solves These PFAS Data Challenges
- NLP & OCR for unstructured document extraction
Extracts PFAS data from SDS, PDFs, scanned records, and legacy documents that are not machine-readable.
- Chemical entity recognition (AI trained on chemical nomenclature)
Identifies PFAS compounds across CAS numbers, IUPAC names, trade names, and structural representations.
- Fuzzy matching algorithms for synonym resolution
Links inconsistent chemical names and identifiers to canonical PFAS substances aligned with EPA databases.
- Confidence scoring and human validation workflows
Flags uncertain matches with confidence scores, enabling teams to review and validate high-risk data points.
Is Your Manufacturing Operation Ready to Report?
Most manufacturers overestimate how complete their PFAS data actually is. Before your team invests weeks in manual review, understand where your actual gaps are.
- Map your SDS, ERP, procurement and supplier data sources
- Identify hidden PFAS exposure across your product lines
- Benchmark your readiness against TSCA 8(a)(7) requirements
- Get a clear, actionable compliance roadmap
How Do Manufacturers Submit PFAS Data to the EPA?
Manufacturers submit their TSCA Section 8(a)(7) reports through EPA’s Central Data Exchange (CDX), using a purpose-built reporting interface called PFAS-RT. Understanding this system early matters, because data that is substantively correct but technically malformatted will be flagged or rejected.
Key submission requirements for PFAS-RT:
- All chemical identities must be submitted using EPA-recognized identifiers (CAS numbers, IUPAC names or DSSTox structure identifiers)
- Volume data must be reported by substance, by year, and by facility
- Use classifications must align with EPA’s standard use code taxonomy
- Byproduct and impurity disclosures require separate, structured entries from primary substance reports
- All data must be submitted through a registered CDX account with appropriate company authorization
Many manufacturers are discovering the CDX/PFAS-RT technical requirements only after they have already invested significant effort in data collection. Building submission validation into the workflow from the start, rather than treating it as a final step, significantly reduces the risk of rejected or incomplete submissions.

What Is the Step-by-Step PFAS Compliance Process for Manufacturers?
For manufacturing leadership reviewing this in April 2026, the following sequence is what a defensible, complete submission requires. The timeline is tight but achievable with the right infrastructure in place from the start.
- Confirm your reporting scope. Determine whether your company qualifies as a standard or small manufacturer. Identify every facility and every product line that touched PFAS in any form between 2011 and 2022. Do not base this assessment on your current product portfolio; historical exposure often looks different.
- Audit your chemical data systems. Map every location where chemical information lives: SDS library, ERP, procurement records, QA documentation, lab data and supplier files. Identify what is structured, what is unstructured and what is missing.
- Begin supplier outreach immediately. PFAS as trace impurities or processing aids in purchased raw materials is the highest-risk disclosure gap for most manufacturers. Supplier response cycles are long and non-response rates are high. Document every request and every response from day one.
- Deploy substance-level identification and reconciliation. Manual review at the substance level is not feasible across a typical manufacturer’s material portfolio in the time remaining. AI-driven extraction and chemical resolution is the baseline capability required to produce a complete submission.
- Build audit documentation as you go. Every data source accessed, every resolution decision made, and every supplier communication sent should be logged against the ‘reasonably ascertainable’ standard. Compliance is not only what you submit; it is the documented process behind the submission.
- Validate against CDX/PFAS-RT schema before submission. EPA’s PFAS-RT system has specific technical formatting requirements. Run validation checks against these requirements throughout the process, not just at the end.
- Submit through CDX before October 13, 2026. Allow time for submission review and potential corrections. Submissions flagged by EPA for data quality issues will require follow-up within tight timeframes.
What Happens If a Manufacturer Misses the PFAS Reporting Deadline?
Non-compliance with TSCA Section 8(a)(7) carries both financial and reputational consequences that operate simultaneously.
Financial exposure:
- Civil penalties of up to $37,500 per day per violation
- Penalties accrue from the date of non-compliance, not from the date EPA discovers the violation
- Multiple violations (for example, failing to report multiple substances) can run concurrently
Reputational and operational exposure:
- Enforcement actions and penalty decisions are public record under TSCA
- EPA enforcement post-deadline is expected to be active; the agency has signaled this rule is a priority
- Customers and partners in regulated industries increasingly require TSCA compliance documentation in supplier qualification processes
For most mid-to-large manufacturers, the cost of a compliant submission, even when AI-assisted tooling is required, is a fraction of a single day’s maximum penalty exposure.
Six Months. One Deadline. Start with a Clear Picture.

The Bottom Line for Manufacturers
TSCA Section 8(a)(7) was not designed with manufacturing data infrastructure in mind. It was designed to generate comprehensive national PFAS information, and the compliance burden falls on whoever manufactured or imported the substances, regardless of how their systems were originally built.
The manufacturers who will complete a defensible, accurate submission by October 13 are not necessarily those with the most resources. They are the ones who recognized early that this is a data systems problem and who deployed the right infrastructure to solve it.
The window is open. The deadline is fixed. What your operation does in the next six months determines the outcome.

Frequently Asked Questions: PFAS Reporting for Manufacturers
Yes. TSCA Section 8(a)(7) covers PFAS that appear as byproducts, impurities or processing aids, not only intentionally manufactured substances. If PFAS were generated or present in your operations in any form between 2011 and 2022, they are within scope.
The reporting period covers January 1, 2011 through December 31, 2022. This means manufacturers must reconstruct or locate records covering up to 14 years of production history.
EPA applies a ‘known or reasonably ascertainable’ standard. You are not required to have perfect records, but you are required to document a good-faith effort to locate data. Where records are missing, manufacturers should document what was done to try to recover them and provide best available estimates with appropriate caveats.
PFAS-RT is EPA’s dedicated reporting interface for TSCA Section 8(a)(7) submissions, accessed through EPA’s Central Data Exchange (CDX). Manufacturers must register a CDX account with appropriate company authorization before the submission period opens and must format data to meet PFAS-RT’s technical schema requirements.
Manufacturers are expected to pursue supplier disclosure and document that outreach. If a supplier does not respond or cannot confirm, manufacturers may need to rely on alternative documentation such as chemical testing, industry databases or material specifications. All efforts to obtain the information should be logged as part of the ‘reasonably ascertainable’ record.
Civil penalties can reach $37,500 per day per violation. Because TSCA violations can encompass multiple substances and multiple reporting failures simultaneously, total exposure for a multi-product manufacturer can be substantial. Enforcement actions are also public record.
Standard manufacturers must submit by October 13, 2026. Qualifying small manufacturers, generally those with under $12 million in annual sales and fewer than 100 employees, have an extended deadline of April 13, 2027. If your operation does not clearly meet both criteria for the small manufacturer definition, assume the October deadline applies.
