What is TSCA Section 8(a)(7) PFAS reporting?

TSCA Section 8(a)(7) requires certain manufacturers and importers to report information to the U.S. Environmental Protection Agency (EPA) about PFAS that they manufactured, including imported PFAS, during the applicable historical reporting period.

The original rule covers PFAS manufactured or imported for commercial purposes during 2011 through 2022 and requires information relating to areas such as production volumes, uses, byproducts, disposal, worker exposure, and environmental and health effects.

However, the implementation timeline has changed.

In April 2026, EPA finalized an extension that moved the start of the reporting period to 60 days after the effective date of EPA's forthcoming revision to the PFAS reporting rule. EPA is reviewing proposed changes to the scope and exemptions before issuing that revision.

So manufacturers should separate two questions:

1. Does the company potentially fall within TSCA 8(a)(7)?
2. When and under what final requirements must the information be submitted?

The first question can be investigated now. The second remains dependent on EPA's forthcoming rule revision.

Who needs to consider TSCA PFAS reporting?

The original TSCA 8(a)(7) rule applies to persons that manufactured, including imported, PFAS during the lookback period.

"Manufacture" under TSCA includes importation.

This distinction matters for manufacturers of complex products.

A company does not automatically become a TSCA PFAS reporter simply because it buys a PFAS-containing component from a U.S. supplier.

EPA's guidance distinguishes between manufacturing/importing a PFAS chemical substance and merely processing a PFAS that was purchased domestically.

This is why "our product contains PFAS" and "we have a TSCA 8(a)(7) reporting obligation" should not be treated as the same question.

What is the TSCA PFAS lookback period?

The original rule looks back to PFAS manufactured, including imported, between January 1, 2011 and December 31, 2022.

The historical nature of the rule creates a major data challenge.

A manufacturer may need to investigate information that is more than a decade old.

That information may be spread across:

• ERP systems
• Product databases
• Chemical inventories
• Supplier records
• Import documentation
• Procurement systems
• Legacy spreadsheets
• Historical product specifications
• Archived compliance declarations
• M&A records

EPA's guidance states that reporting is required for each PFAS for each year in the lookback period in which the PFAS was manufactured, including imported.

That makes historical data reconstruction one of the most important operational issues in this cluster.

For that specific problem, see:

TSCA PFAS Reporting: Historical Supplier Data

What information does TSCA PFAS reporting require?

The original rule requires information across multiple categories.

These include information about:

• Chemical identity
• Manufacturing and import activity
• Production volumes
• Uses
• Byproducts
• Disposal
• Worker exposure
• Environmental effects
• Health effects

EPA's reporting instructions describe the information that must be collected and submitted through the agency's reporting system.

For manufacturers, this means the challenge is not simply identifying a PFAS name.

The company may need to reconstruct how the PFAS was manufactured or imported and what happened to it during the relevant period.

What data should manufacturers collect?

A practical internal data model should connect the regulatory requirement to the underlying business records.

The important word here is historical.

A company may have excellent current compliance data while still having significant gaps for 2011–2022.

The "known or reasonably ascertainable" information standard

One important concept in EPA's guidance is that reporting is based on information that is known or reasonably ascertainable.

EPA explains that this includes information in a person's possession or control and information a reasonable person similarly situated may be expected to possess, control or know.

That has a practical implication:

Do not assume that missing information means the historical activity can simply be ignored.

Instead, manufacturers should establish what information exists and what can reasonably be reconstructed.

For example:

ERP data → procurement records → supplier information → historical product records → import documentation

may collectively provide information that is not available from any one system.

Why historical supplier data matters

Historical supplier information can become particularly difficult when:

• Suppliers have changed
• Components have been discontinued
• Supplier declarations were never digitised
• Product lines have changed
• ERP systems were replaced
• Companies were acquired
• Business units were divested
• Records were archived
• PFAS was not previously treated as a reporting priority

A current supplier declaration does not necessarily answer a historical reporting question.

For example:

Supplier A confirms that Component X currently contains PFAS.

That does not automatically establish:

What PFAS was present in Component X in 2013?

The two questions require different evidence.

That is why historical PFAS reporting deserves its own supporting page:

TSCA PFAS Reporting: Historical Supplier Data

How should manufacturers approach historical PFAS data?

A practical workflow is:

1. Identify potentially reportable PFAS

Start with chemical inventories, product information and known PFAS materials.

2. Establish the historical period

Review activity across the 2011–2022 lookback.

3. Identify gaps

Determine which years, substances, suppliers or activities lack evidence.

4. Search internal records

Use procurement, ERP, import, production and product records.

5. Engage suppliers where appropriate

Request historical information where internal records cannot establish the required facts.

6. Validate the evidence

Check whether information relates to the correct substance, year, product or activity.

7. Build the reporting dataset

Structure information according to the applicable EPA reporting requirements.

8. Maintain supporting records

Preserve the evidence used to establish the submission.

What about PFAS-containing articles?

This is an area where manufacturers need to be particularly careful.

EPA's original rule includes specific provisions concerning imported articles, and EPA has also proposed changes to the scope of reporting requirements, including an exemption for imported articles. Those proposed changes are not the same thing as the current final reporting rule.

Therefore, manufacturers should not publish or operationalise a blanket statement such as:

"PFAS-containing imported articles are exempt from TSCA reporting."

The status of proposed exemptions needs to be checked against the final EPA revision when issued.

The safer compliance approach is:

Identify the activity → determine whether it falls within the current rule → monitor EPA's revision → reassess if the final rule changes the scope.

What changed in 2026?

The TSCA PFAS reporting timeline is currently in transition.

EPA's April 2026 action moved the reporting-period start from April 13, 2026 to 60 days following the effective date of the forthcoming revision to the PFAS 8(a)(7) rule. EPA said the change provides additional time to review comments and refine the rule. (US EPA)

EPA's current rule page also states that its November 2025 proposal included potential exemptions or modifications involving:

• PFAS in mixtures or products at concentrations of 0.1% or lower
• Imported articles
• Certain byproducts
• Impurities
• Research and development chemicals
• Non-isolated intermediates

These were proposed changes and should not be treated as final until EPA completes the rulemaking.

What manufacturers should do with this uncertainty

Do not stop preparation.

Instead, separate:

Current rule requirements

from

Proposed changes

from

Final future requirements

That prevents the compliance team from building its reporting process around provisions that may change.

TSCA PFAS reporting vs PFAS product compliance

These are related but different activities.

This distinction is important for manufacturers.

A company can have PFAS-containing products without necessarily having the same TSCA reporting obligation as a company that manufactured or imported the PFAS chemical substance.

Where supplier data fits into TSCA reporting

Supplier information can be an important part of historical reconstruction, particularly when manufacturers do not directly control the underlying chemical or material information.

The workflow can look like:

Historical product

↓

Component

↓

Supplier

↓

Material / substance

↓

PFAS identification

↓

Historical activity

↓

TSCA assessment

The supplier should not automatically be expected to provide the complete TSCA submission.

The manufacturer remains responsible for determining what information is required and how the available evidence supports its reporting position.

For the supplier-data workflow itself, see:

PFAS Supplier Data & Chemical Transparency for Manufacturers

What records should manufacturers retain?

A strong recordkeeping process should allow the company to reconstruct why it reached its reporting conclusion.

Relevant records may include:

The objective is not simply document retention.

It is traceability from the reported information back to the underlying evidence.

How should manufacturers prepare now?

The most useful preparation is a structured historical-data assessment.

Step 1: Establish the PFAS universe

Identify PFAS that may have been manufactured or imported.

Step 2: Map the 2011–2022 period

Determine which years require investigation.

Step 3: Identify historical data sources

Map ERP, procurement, import, supplier and product records.

Step 4: Find information gaps

Separate known information from information that needs reconstruction.

Step 5: Prioritise supplier outreach

Contact suppliers where their historical information is necessary to establish the reporting position.

Step 6: Build an evidence trail

Record where each important data point came from.

Step 7: Monitor EPA's rule revision

Reassess the reporting dataset and process when EPA finalises its forthcoming changes.

A scalable TSCA PFAS reporting workflow

For companies with large product portfolios, the process can be structured as:

Regulatory requirement

→ PFAS identification

→ Historical activity

→ Supplier/material evidence

→ Product/component mapping

→ Data validation

→ Reporting dataset

→ Submission

→ Record keeping

→ Regulatory monitoring

The important point is that reporting should be the end of the data chain, not the beginning.

If the underlying information is incomplete, simply putting a reporting form in front of the compliance team does not solve the problem.

The bottom line

TSCA PFAS reporting is fundamentally a historical data problem.

The regulation may be straightforward to describe. Reconstructing the information needed to support a submission can be much harder.

Manufacturers need to connect:

PFAS → historical activity → suppliers → materials → products → reporting information → evidence

The companies that start that reconstruction early will be in a much stronger position when EPA finalises its next set of requirements.

The immediate priority is therefore not guessing the final deadline.

It is knowing what PFAS-related manufacturing or import activity occurred between 2011 and 2022, what evidence exists, where the gaps are, and how those gaps can be resolved.
