A supplier writes “PFAS-compliant” on a quotation and the brand files it. The phrase is not dishonest, exactly. It is empty. The same legging can sit comfortably inside California's limit and nowhere near France's, because the two markets do not use the same number, the same measurement, or even the same kind of rule. This guide sets out what each market actually asks for, why every one of them wants a signature and none of them names a test method, and what a brand should hold before bulk.
The short answer
- “PFAS-compliant” is not a claim until it names a market and a measure. California's apparel ceiling is 100 ppm total organic fluorine; France's is 25 ppb for an individual targeted PFAS — roughly four thousand times tighter, on a different measurand.
- Rules come in three shapes, and each demands different evidence: an intent test (New York today, Maine), a numerical threshold (California, Vermont, France), and a labelling or reporting duty (Washington, Connecticut, Colorado, Minnesota).
- Every one of these regimes asks for a signed certificate or written statement from the manufacturer. None of them prescribes a test method — so the brand decides what evidence sits behind the signature.
- A supplier's signature does not transfer your obligation. The declaration you hold from a partner facility supports your certificate to the state; it does not replace it.
“PFAS-compliant” is not a statement about anything
The phrase travels well because it sounds like a test result. It is not one. California's AB 1817 has banned PFAS in apparel since 1 January 2025, catching anything where PFAS were intentionally added for a functional effect or are present at or above 100 ppm total organic fluorine. France's Decree No. 2025-188, with implementing Decree No. 2025-1376 signed on 30 December 2025, has been in force since 1 January 2026 and sets 25 ppb for an individual targeted PFAS, excluding polymers.
One hundred ppm is one hundred thousand ppb, so the French limit for a single targeted compound is about four thousand times tighter — and the two are not measuring the same thing. Total organic fluorine is a screening proxy that sweeps up all organofluorine present. France stacks four separate figures instead: 25 ppb per targeted PFAS excluding polymers, 250 ppb for the sum with precursor degradation excluding polymers, 50 ppm for PFAS including polymers, and a duty on the manufacturer to prove the origin of total fluorine on request once it exceeds 50 mg/kg.
A garment can therefore clear California on a laboratory report and be nowhere near French compliance on the same fabric. A usable statement names five things: the market, the measurand, the number, the method, and the date of the report on the fabric in your order. Anything shorter is a sentence somebody typed, and it will not survive the first compliance desk that reads it properly.
Three shapes of rule, three kinds of evidence
The first shape is an intent test. New York's apparel ban as it currently stands, and Maine's, turn on whether PFAS were intentionally added, with no number attached at all. The evidence an intent test wants is documentary and upstream: what was added, at which stage, by which entity. A fluorine result does not answer that question. A chain of declarations covering the spin finish, the dye house, the print binder and any water-repellent treatment does.
The second shape is a number. California, Vermont and France all set one, and they agree neither on the figure nor on what is being measured. Here the evidence is a laboratory result on the correct measurand, with a detection limit low enough to be meaningful against the limit in question — a report whose detection limit sits above the threshold you have to meet tells you nothing at all, however official the letterhead.
The third shape is a duty to disclose rather than to comply. Washington wants a report, Connecticut a label and a prior notification, Colorado a disclosure on severe-wet-conditions apparel, Minnesota a filing. None of these asks whether the garment passes. They ask whether you know, by a fixed date — so the evidence required is knowledge of what is actually in the garment, held early enough to file it or print it. Not knowing is itself the failure.
The US map, and the date each rule actually bites
California's ban has been live since 1 January 2025 at 100 ppm total organic fluorine, stepping to 50 ppm on 1 January 2027, and it covers PFAS intentionally added for a functional effect as well as PFAS simply present at or above the threshold. Severe-wet-conditions outdoor apparel is exempt from the ban until 1 January 2028 but has required a “Made with PFAS chemicals” disclosure since 1 January 2025. The manufacturer must supply distributors and sellers a certificate of compliance signed by an authorised official, and retailers relying on it in good faith are shielded. DTSC enforcement begins 1 July 2030 — a date for enforcement, not for the obligation.
New York is about to change shape. Its ECL 37-0121 apparel ban has been live since 1 January 2025 on an intent basis with no ppm figure; severe-wet-conditions outdoor apparel follows on 1 January 2028. NYSDEC is directed to set an enforceable numerical threshold by 1 January 2027, explicitly “regardless of whether such PFAS are intentionally or unintentionally added” — an intent test converting into a number, with unintentional presence starting to count. As of this writing the published NYSDEC guidance still shows only the 2025 and 2028 dates, no ppm figure and no test method. Sellers must obtain a written statement from the manufacturer, signed by an authorised official, kept on site rather than filed with the state. Penalties run to $1,000 per day of continuing violation and $2,500 for a second violation.
Then there is the 1 January 2026 cluster. Vermont: textiles at 100 ppm total organic fluorine until 30 June 2027, then 50 ppm. Maine: a sales prohibition on most textile articles with intentionally added PFAS. Washington: reporting only, no ban, for apparel intended for extreme or extended use, triggered above 50 ppm total organic fluorine, with the report due 31 January 2027. Connecticut arrives on 1 July 2026 with labelling — “Contains PFAS”, “Made with PFAS” or “Made with intentionally added PFAS” — plus prior written notification to DEEP, and a full ban from 1 January 2028.
Further out, Colorado bans outright on 1 January 2028 and New Mexico covers textiles from 1 January 2028 with reporting from 2027. Minnesota is the state most often reported wrongly: apparel is not among the eleven categories banned from 1 January 2025 — those are carpets and rugs, cookware, cosmetics, cleaning products, dental floss, juvenile products, menstruation products, ski wax, textile furnishings and upholstered furniture. For apparel the live hooks are PFAS reporting to MPCA, which was due 1 July 2026 with annual February updates, and the full ban on 1 January 2032. If an adviser tells you Minnesota bans PFAS in clothing today, check every other date they have given you.
France, and why the European picture is not the EU
France is the strictest jurisdiction by a wide margin, and it got there nationally rather than through Brussels. Decree No. 2025-188, with implementing Decree No. 2025-1376 signed on 30 December 2025, has banned the manufacture, import, export and placing on the market of clothing, textiles and footwear containing PFAS since 1 January 2026. The four figures again: 25 ppb per individual targeted PFAS excluding polymers; 250 ppb for the sum with precursor degradation, excluding polymers; 50 ppm for PFAS including polymers; and, above 50 mg/kg total fluorine, an obligation on the manufacturer to prove its origin on request. That last one is a burden of proof rather than a limit, and worth reading twice.
There are exemptions: personal protective equipment under EU Regulation 2016/425, re-waterproofing agents for PPE, and articles containing at least 20% post-consumer recycled content. There is a twelve-month sell-through for stock manufactured before 1 January 2026, expiring 1 January 2027, and the scope extends to all textiles by January 2030. Whether a specific style falls inside an exemption is not a question a supplier should answer for you — it turns on the article and how it is placed on the market, and belongs with advisers who answer for France.
The EU-wide picture is thinner than the headlines suggest. The universal PFAS restriction proposed in January 2023 is still not adopted — the ECHA review is ongoing and there is no date. Separately, a PFHxA restriction under REACH Annex XVII takes effect in April 2026, and C9–C14 PFCAs are already banned. So for most activewear the binding European constraint today is a French national decree, not a Union-wide one. A brand shipping into France and elsewhere in the EU either builds the whole program to the French numbers or geo-fences its distribution, and geo-fencing is harder than it sounds once goods pass through EU distributors.
Every regime wants a signature; none of them names a test
This is the structural feature nobody designs for. California requires the manufacturer to hand distributors and sellers a certificate of compliance signed by an authorised official, and shields retailers relying on it in good faith. New York requires the seller to hold a written statement from the manufacturer, signed by an authorised official. France puts the burden of proving fluorine origin on the manufacturer on request. What none of these does is prescribe a test. California names total organic fluorine as the metric; the statute names no method, no laboratory accreditation and no sampling protocol.
That gap lands on the brand in a very specific way. On one side is a facility that will sign whatever template you send, because a signature costs nothing and the declaration is written in a language and a legal system it does not answer to. On the other is a retailer's compliance desk that will not list the product without a laboratory report showing a method and a detection limit. The statutes do not settle that argument. The specification does — before bulk, while the fabric is still a decision rather than an inventory.
And the number that bites first is not in any statute. Private Prop 65 settlements in California have set less than 50 ppm total fluorine for pants, skirts and cooling or water-resistant hats, with further PFOA testing if that is exceeded (Bureau Veritas settlement bulletin, 30 July 2026). Note total fluorine, not total organic fluorine: a broader measurand, so a stricter screen than California's own statutory ceiling, arriving through private plaintiffs rather than an agency whose enforcement date is 2030. We cover that in its own guide. The point here is narrower — the statutory number is not always the operative one.
What to ask a partner facility for, and what to write into the specification
Start with who signs. Ask for a declaration from the legal entity that actually applies the chemistry — usually the mill, dye house or finisher, not the garment factory — naming the article, the season and the specific fabric quality rather than the company in general. Require it to cover components, not just the face fabric: elastic, thread, trims, bonded tapes, prints and binders, and any water-repellent finish. Ask directly whether a DWR is applied and what it is called. Then check holder name and scope the same way you would check a certificate, rather than filing the PDF unread.
Where a market imposes a number, ask for a third-party report and read five fields before accepting it: the laboratory, the measurand, the method, the detection limit, and the sample description with a date. Total organic fluorine, total fluorine and a named-PFAS target list are three different questions, and a report answering one is not evidence about the other two. Screen first and speciate second, and make sure the sample described is the fabric in your order rather than an archive swatch.
Then write it down. Name every market the program ships into and state that the tightest applicable limit governs the entire run, so one bulk does not have to be split at the port later. State the numeric limit with its measurand and the method reference you accept. Prohibit PFAS-based water repellents by name, and require written notification before any substitution of mill, dye house or finish, because a change downstream quietly voids what you were relying on. Tie the declaration and the test report to bulk approval or final payment, so they are obligations rather than favours asked for after shipment.
One line matters more than the rest: no supplier signature transfers your obligation. These statutes put the certifying duty on the manufacturer, and a brand selling under its own label is generally the manufacturer for that purpose — how each state defines the term for your set-up is something to confirm with advisers, not to assume. Whatever a partner facility signs, the certificate the state reads has your name on it. The upstream declaration supports your signature; it does not stand in for it.
Where a supply-chain partner fits — and where it does not
SEAMDANCE is a buyer-side trading and supply-chain management company in Xiamen, founded in 2018, coordinating independent specialist factories, mills and dye houses. On a chemical requirement our work is upstream and administrative. We ask which markets a program is going into before the specification is finalised, so the tightest applicable limit governs the material from the start rather than surfacing at a border. We write that limit into the material specification before bulk — the only stage at which changing it is cheap.
We obtain the partner facility's declarations and verify holder and scope rather than forwarding whatever arrives, and where a buyer names a standard we route the fabric to a third-party laboratory with the report issued to the buyer. What we do not do matters just as much. We do not operate a laboratory and do not test. We hold no certification of our own and cannot certify a result. And we cannot sign a certificate of compliance on a brand's behalf — no supply-chain partner can, and one that offers to has told you something about how it treats documentation generally.
The practical rhythm helps more here than it looks. Quotes inside 24 hours, stock samples in three to four days and custom development in around seven, MOQ from 100 pieces on stock styles and 300–500 for custom. On a chemical requirement that means the question can be settled at sample stage, on a small quantity, rather than argued about across a container after the fabric is knitted. Inspection to AQL 2.5 covers workmanship and construction; it is not a chemical test, and no inspection standard is.
This article is general information, not legal advice. Thresholds, effective dates and the scope of each rule change — several of the rules above are drafted to change on a fixed date, and one of them, New York's numerical threshold, has not been published yet. Nothing here says that a brand or a product is compliant. Confirm the current position for each market you sell into, with advisers who answer for that market.
