Customer PFAS Request: What to Ask Suppliers First

Scope the request before collecting evidence：When a customer says “confirm PFAS,” the first risk is treating an undefined request as one legal question

A customer PFAS request may point to the EU-wide PFAS restriction proposal, an individual PFAS-related obligation already in force under the POPs framework, PFAS conditions for food-contact packaging under PPWR, a US federal or state requirement, or the customer’s own restricted-substance list. It may ask about intentional use, a named CAS list, total PFAS, total fluorine, organic fluorine, or a PFAS-free marketing statement. Those questions do not share one definition, threshold, product scope or evidence method.

The first supplier round should therefore not demand an unbounded global claim that every PFAS is absent, and it should not treat one generic declaration as a product conclusion. Translate the customer condition into fields that can be answered, then link parts, materials, uses, sources, existing records and change controls. If a source cannot support a conclusion, state that limit rather than fill the gap with an inference.

Bottom line first

Confirm the customer’s legal text, RSL, substance definition, threshold, product scope and requested deliverable before asking suppliers for an answer.
At the review date, the EU-wide PFAS restriction remained a restriction proposal in the ECHA process; do not merge it with individual PFAS-related obligations already in force.
PPWR food-contact packaging questions, POPs or other legal questions, US or state requirements and customer RSLs each need their own applicability and evidence field.
A not-intentionally-added statement describes a supplier’s known use; it is not a conclusion that every PFAS is absent or that every legal definition is met.
Total-fluorine or organic-fluorine screening can be a limited risk signal, not direct universal proof of PFAS status. Targeted analyses answer only their analytes and samples.
Build material mapping, scoped declarations, upstream records and change notification first; choose targeted verification only for a defined evidence gap.
On 8 August 2026, the EU-wide PFAS restriction remained a proposal: RAC adopted its final opinion on 3 March, SEAC agreed its draft opinion on 11 March, and ECHA issued the consultation outcome on 3 June.

Information needed before deciding

01 | Request basis: identify whether the driver is legal text, a state requirement, customer RSL, purchasing specification or marketing claim, and retain its version and date.
02 | Substance definition: identify the PFAS definition, CAS or substance list, whether precursors, polymers, salts, total fluorine or organic fluorine are included, and any threshold.
03 | Product and market: identify the product, part, packaging, food-contact use, destination market and supply-chain role being asked about.
04 | Material and part mapping: require the reply to name the grade, part number, revision, colour, coating, batch or manufacturing location rather than only a product family.
05 | Concentration or range: ask for a known concentration, range, reporting limit, or—where formula disclosure is restricted—the supportable risk range and basis for it.
06 | Fluoropolymer: ask whether PTFE, PVDF, FEP, PFA or another fluoropolymer is used, why it is used and where it appears in the product.
07 | Processing aids: ask about fluorinated processing aids, mould-release agents, surface-treatment aids or other process chemicals that may remain in the article.
08 | Functional and attached layers: ask separately about coating, ink, adhesive, membrane, lubricant, sealant and multilayer construction, not only the substrate.
09 | Upstream declaration: obtain dated and scoped declarations from the material maker, formulator or upstream supplier, and record how far they are traceable.
10 | Formula or material evidence: where confidentiality applies, request material specifications, use statements, controlled third-party confirmation or other evidence that defines the review scope.
11 | Change notification: confirm whether formula, source, processing aid, recycled content, colour, coating, site or supplier changes trigger notice and reassessment.
12 | Testing information: if a report exists, identify the sample, material, method, analytes, detection or reporting limit, report date and PFAS scope it does not cover.

Practical decision flow

Translate the customer wording into a decision scope

Obtain the original customer specification, purchasing clause or RSL. Record its definition, threshold, product scope, market, deadline and evidence format. If it only says “PFAS-free,” request written clarification of the definition and acceptable evidence.

Map the product, packaging and materials

Use BOM, packaging hierarchy, material grade and supplier data to identify substrates, coatings, inks, adhesives, membranes, lubricants and processing sources. Flag food-contact packaging separately.

Use the twelve questions for a traceable supplier reply

Do not send an empty PFAS form. Ask suppliers to link declarations, material information, upstream records and available reports to identified materials or parts, and to state what they cannot confirm.

Keep declarations, upstream evidence and analysis separate

Store not-intentionally-added statements, named-substance declarations, material specifications, total-fluorine screening and targeted analysis as different evidence types. Each should retain its sample, definition and relationship to the legal or customer request.

Strengthen only the defined gap

Where material use, customer definition or upstream information reveals a high-risk gap, consider targeted testing, controlled third-party review, material substitution or escalation. If it cannot be confirmed, communicate the limitation rather than speculate.

Make the answer maintainable through change control

Link the response to versions, suppliers and products. A raw-material, formula, process, coating or market change should trigger review rather than allow an old statement to be reused without checking.

What different evidence can support

Evidence	What it can support	Important limitation
Material- or part-mapped PFAS or substance declaration	A dated supply-chain statement for an identified material or part and stated legal or customer substance scope.	Its value depends on the definition, signatory, material mapping, version, threshold and change control. A generic PFAS-free phrase does not by itself cover every rule.
Not-intentionally-added statement	The supplier’s statement that it does not knowingly use a defined PFAS scope in a formula or process.	It is not a conclusion that every PFAS is absent, and may not cover impurities, residues, upstream formulations, recycled content or a customer’s different definition.
Material specification, use statement and fluoropolymer information	Material grade, function, location, fluoropolymer status and potentially relevant coating or process route.	A material name or resin family does not establish complete chemical composition; colourants, additives, processing aids and surface layers can change risk.
Upstream record or controlled third-party confirmation	That upstream documentation or a confidential review has considered a stated scope without releasing the complete formula to every downstream customer.	Record who reviewed what, which material and conclusion limits apply. Confidential review does not extend automatically to every model or unreviewed definition.
Total-fluorine or organic-fluorine screening	Limited comparative information about a fluorine signal or screening result for the stated sample.	It cannot directly identify every PFAS, attribute its source or serve as cross-regulation proof. Read it with the method, sample and reporting limit.
Targeted PFAS analytical report	Results for the report’s stated sample, method, analytes and reporting limits.	It answers only the tested substances and sample. It cannot be extended to different materials, unlisted substances, other batches or every PFAS.

Common mistakes

Mistake：Forwarding the customer’s one-line PFAS request to the supplier unchanged.

**Risk：**The supplier may answer a different definition while the company treats it as a response to the customer specification.

**Better approach：**Confirm the legal or customer basis, definition, threshold, product and evidence format before issuing a scoped request.

Mistake：Describing the EU-wide restriction proposal as an already universal ban.

**Risk：**Proposal status, existing individual obligations and customer requirements become mixed together.

**Better approach：**Label the proposal, current POPs or other legal rules, PPWR food-contact conditions and customer clauses separately.

Mistake：Reading not intentionally added as absence of every PFAS.

**Risk：**Formula, residue, impurity, definition and analysis scope are left unexplained, creating an overbroad conclusion.

**Better approach：**Preserve the original wording and definition; use material, upstream or targeted analytical evidence for a specific remaining gap.

Mistake：Treating a total-fluorine result as total PFAS or legal conformity.

**Risk：**A screening signal, analyte list and legal condition are improperly substituted for one another.

**Better approach：**Treat total fluorine as a limited indicator, state method and limits, and select further evidence for the actual question.

Mistake：Asking only about the plastic substrate and ignoring coatings, inks, adhesives, membranes and processing aids.

**Risk：**Potentially relevant functional or surface layers are omitted from the evidence inventory.

**Better approach：**Ask by BOM, packaging construction and process layer so every functional and attached material is in scope.

Mistake：Demanding an unbounded absolute claim that every PFAS is absent worldwide.

**Risk：**The question is not verifiable, its definition is unclear and the answer may have no decision value.

**Better approach：**Bound the question by customer definition, legal scope, material and use, and allow suppliers to identify what remains unconfirmed.

Company action checklist

Create a PFAS customer-request register holding the original clause, version, definition, threshold, product scope and deadline.
Build a mapping of each product and package to parts, materials, coatings, inks, adhesives, membranes and process sources.
Use the twelve first-round questions and require suppliers to identify the material or part number, version and evidence limits in every reply.
Manage declarations, material specifications, upstream evidence, screening and targeted reports in separate fields rather than one undifferentiated status.
Set higher review priority for food-contact packaging, fluoropolymers, surface treatment, recycled content and material-specific evidence gaps.
Add notification and reassessment triggers for formula, source, processing aid, coating, manufacturing site and recycled-content changes.
Separate evidenced facts, supplier statements, unresolved items and planned strengthening steps in the customer response.

Manager summary

A PFAS request should be managed as a scoped evidence decision, not as a search for a generic certificate. Leadership should require a traceable link between the customer definition, product and material mapping, supplier records, analytical limits and change controls. Where the chain does not support a conclusion, the business should state the limitation and decide whether targeted evidence, a material change or escalation is appropriate.

Frequently asked questions

Can we simply ask a supplier to sign the customer’s PFAS-free wording?

Do not copy the wording without first confirming the customer’s PFAS definition, substance list, threshold, product scope and acceptable evidence. If the supplier can only make a not-intentionally-added statement, preserve that narrower wording and its limits.

Is the EU-wide PFAS restriction already a current universal prohibition?

At the review date, it should be handled separately from binding rules already in force. ECHA process information describes scientific opinions and the subsequent decision path; it does not replace an adopted and published restriction text. Confirm current official law and dates for the actual product.

Does a negative total-fluorine result prove there are no PFAS?

No. Total- or organic-fluorine results depend on the sample, method, reporting limit and source of the signal, and do not list every PFAS. State the screening question it answers and what remains outside its scope.

Can food-contact packaging and a general product use the same PFAS declaration?

Some underlying information may overlap, but their scope should not be assumed to be the same. Confirm food-contact status, packaging use, PPWR conditions and other applicable law, then link the declaration to the actual packaging material and use.

What can we request when a supplier will not disclose its formula?

Request a material- or part-specific statement, material specification, use and fluoropolymer information, upstream declaration, controlled third-party confirmation, available analytical reports and change notification. Clearly document any scope that remains unconfirmed.

Must every PFAS customer request immediately lead to testing?

There is no universal answer. Compare the request, material risk, supplier evidence, existing reports and change history first. Targeted analysis can strengthen a defined gap, but its analyte and sample scope must also be interpreted correctly.
