How Should US Firms File PFAS Reports in Practice?
Manufacturers and importers now have to reconstruct years of PFAS activity for EPA under TSCA Section 8(a)(7). This practical walkthrough explains how to define scope, assemble records, file through EPA CDX, and recover from common data gaps.
How Should US Firms File PFAS Reports in Practice?
When EPA reporting obligations reach back to PFAS manufactured or imported since January 1, 2011, the difficult part is usually not the online form. It is finding reliable historical information across purchasing, customs, product stewardship, and manufacturing records. If you are asking how should us firms file pfas reports, start by treating the submission as a documented data-reconstruction project, not a last-minute questionnaire.
1. Confirm that the company and chemicals are in scope
Begin with the legal entity that manufactured a PFAS in the United States or imported a PFAS, mixture, or article containing a PFAS. Under 40 CFR 705.7, the reporting obligation applies to each covered manufacturer and importer, including companies that imported PFAS-containing articles.
Use the definition in 40 CFR 705.3 rather than relying on a supplier’s marketing description. The definition is structure-based and covers substances containing specified carbon-fluorine arrangements. A CAS number is useful for matching records, but the absence of a CAS number does not by itself take a substance outside the rule.
The lookback period begins January 1, 2011. There is no general tonnage threshold that removes a covered PFAS from the reporting exercise. Small quantities, imported components, and legacy products therefore need a deliberate screening decision.
This is also where many teams ask which products require EPA PFAS reporting. The answer is not limited to finished consumer products: industrial chemicals, formulated mixtures, components, and imported articles may all matter if a covered PFAS was manufactured or imported.
2. Build a defensible PFAS inventory
Create one working register before opening EPA’s Chemical Data Exchange (CDX). Give each row a substance identifier and connect it to the relevant legal entity, facility, supplier, product, and year.
A useful first-pass process is:
- Export chemical and raw-material purchasing data for 2011 onward, including inactive and discontinued items.
- Search safety data sheets, technical data sheets, bills of material, supplier declarations, and product specifications for fluorinated chemistry.
- Reconcile import records against HTS classifications, broker files, commercial invoices, and customs entry data.
- Ask suppliers for composition confirmation, including confidential composition information where appropriate.
- Record the basis for every inclusion, exclusion, and unresolved identity.
Do not search only for the term “PFAS.” Older documents may identify a fluoropolymer, processing aid, surfactant, trade name, or internal material code instead. A supplier statement saying “PFAS-free” should be retained with its date and scope; it should not automatically be applied to earlier shipments or unrelated grades.
For importers, the EPA PFAS reporting data requirements for importers include information about the imported chemical or article, production or import volumes, uses, and related operational details. Allocate ownership early between regulatory affairs, procurement, trade compliance, engineering, and finance. No single department normally holds the complete record.
3. Reconstruct the information EPA expects
For each in-scope PFAS, map the available records to the data categories in 40 CFR 705.15. These include chemical identity, physical form, industrial processing and use, consumer and commercial use, production or import volume, byproduct information, disposal, environmental release, worker exposure, and known or reasonably ascertainable health and environmental effects.
Separate measured data from estimates. If annual import volume is known from customs records but use or release information is incomplete, preserve both the number and the method used to estimate the missing field. A short methodology note is more useful than an unexplained number copied into the form.
For imported articles, determine whether the PFAS was intentionally added, present in a coating or treatment, embedded in a component, or identified only through testing. Document the article description, supplier, country of origin, import volume, and the PFAS concentration or quantity basis used for the report.
Do not invent precision. Convert units consistently, state whether a quantity is gross mixture weight or PFAS weight, and keep the source record. If records cover several years, make the reporting year and aggregation rule explicit.
4. File through EPA CDX in the correct sequence
The submission is made electronically through EPA CDX using the PFAS reporting tool. Set up the company account and authorized official before the internal review is complete; account creation, role assignment, and signature authority can take longer than expected.
Enter the legal entity and facility information first, then create the chemical or article records, add production and import data, and complete the use, exposure, release, disposal, and effects fields. Run the tool’s validation checks, download or retain a copy of the completed submission, and have a technical reviewer compare the final entries with the source register.
The TSCA Section 8(a)(7) PFAS reporting steps should end with formal certification by an authorized official. Certification is not a general “best efforts” statement. It confirms that the submission was reviewed and that the information is complete and correct to the submitter’s knowledge and belief.
Keep the CDX submission identifier, validation messages, signed certification, uploaded documents, data workbook, calculations, supplier correspondence, and approval record together. Under 40 CFR 705.20, retain the supporting records for at least five years from the date of submission.
5. Control the deadline and fix weak records
The rule’s reporting period and deadline are set in 40 CFR 705.18 and have been subject to EPA implementation notices. The final rule established a reporting period beginning November 12, 2024; the extended deadline was May 8, 2025 for most reporters, with November 10, 2025 for small manufacturers that import PFAS-containing articles. Confirm the applicable deadline and any current EPA notice before filing because agency extensions and CDX instructions can change the practical timetable.
A common mistake is treating an incomplete supplier response as proof that no PFAS was imported. Recover by documenting the request, escalating through procurement, checking customs and technical records, and using a qualified estimate where the rule permits one. Mark assumptions clearly and update the submission if better information becomes available.
Another mistake is filing only manufacturing data while overlooking imported articles. Review product families, spare parts, packaging, coated components, and toll-manufactured goods separately. Also check duplicate reporting: coordinate affiliated entities so the same activity is neither omitted nor reported twice without an explanation.
If a submitted record contains an error, do not silently change the internal file and leave EPA’s record untouched. Review the CDX correction or amendment procedure, preserve the original submission, obtain approval for the revised data, and retain the reason for the change.
Takeaway: make the file auditable
The most reliable answer to how should us firms file pfas reports is to work backward from an auditable submission. Define scope under 40 CFR Part 705, reconstruct the 2011-forward history, distinguish facts from estimates, validate the CDX record, and retain the evidence behind every material answer. That approach gives management a defensible basis for certification and gives the company a usable record for future EPA inquiries.

Frequently asked questions
Does the TSCA PFAS rule cover imported articles?
Yes. Companies that import articles containing a covered PFAS can have reporting duties under 40 CFR Part 705. Screen finished goods, components, coatings, treatments, and other imported articles rather than limiting the review to bulk chemicals.
Is there a minimum quantity below which a PFAS report is not required?
The rule does not provide a general de minimis tonnage threshold that removes covered PFAS activity from the reporting scope. Very small quantities should be documented and assessed under the applicable exemptions and reporting provisions.
What records should a company retain after filing?
Keep the CDX submission and certification, validation results, calculations, source registers, customs records, bills of material, supplier correspondence, and approval records. 40 CFR 705.20 requires covered records to be retained for at least five years from submission.
