Short answer: if you finish fabric for export, assume your buyer now needs it free of PFAS, the “forever chemicals”. The EU restriction on PFHxA, the chemistry behind most C6 fluorocarbon water repellents, applies to consumer clothing, accessories and footwear from 10 October 2026 and to all other textiles from 10 October 2027. France, Denmark and a growing list of US states go further and target PFAS as a whole. A C6 finish is no longer a safe answer. A fluorine-free finish, backed by a test report, is.
Why this matters to Indian mills and finishers
For two decades the standard way to make fabric shed water and stains was a fluorocarbon finish: first long-chain C8 chemistry, then the shorter C6 chemistry that replaced it. Both belong to the PFAS family. Regulators in Europe and the United States now treat PFAS in consumer textiles as something to remove, not manage, and the burden of proof sits with whoever places the product on the market. In practice that is your customer, the brand, importer or retailer, and they pass it straight back to you as a declaration to sign and a test limit to meet.
If any of your export orders still run on a C6 recipe, the time to switch is before a shipment fails a laboratory test, not after.
The rules at a glance
| Market | What is restricted | From |
|---|---|---|
| European Union (REACH, Regulation (EU) 2024/2462) | PFHxA and its salts at 25 ppb or more, and PFHxA-related substances at 1,000 ppb or more, in consumer clothing, accessories and footwear | 10 October 2026 |
| European Union | The same limits for all other textiles, leather, furs and hides (certain protective equipment and construction textiles excluded) | 10 October 2027 |
| France | Consumer clothing and footwear containing PFAS; all textiles from 2030, with limited exemptions | 1 January 2026 |
| Denmark | Consumer clothing and footwear with total fluorine at or above 50 mg/kg | 1 July 2026 |
| California (AB 1817) | Textile articles with intentionally added PFAS or total organic fluorine above 100 ppm; the limit falls to 50 ppm | 1 January 2025; 50 ppm from 1 January 2027 |
| New York | Apparel with intentionally added PFAS; concentration limits to follow | 1 January 2025; limits by 2027 |
| Maine and Vermont | Textiles with intentionally added PFAS | 1 January 2026 |
| Washington and Rhode Island | Apparel and textiles with intentionally added PFAS | 1 January 2027 |
| Colorado | Textile articles, including outdoor apparel for severe wet conditions | 1 January 2028 |
The EU is also preparing a restriction that would cover almost all uses of PFAS. Its scientific committees are finishing their opinions, and adoption is expected in 2027 or 2028. Buyers are not waiting for it.
This summary is for orientation, not legal advice. Check your buyer’s restricted substances list and the current text of each rule, for example Regulation (EU) 2024/2462 and California AB 1817.
What your buyer will actually ask for
- A declaration that no PFAS were intentionally added to the fabric or its finish.
- A test report on the finished fabric, usually total fluorine or total organic fluorine, measured against the strictest limit of the markets they sell into. 50 ppm (50 mg/kg) is the figure that appears most often.
- The safety data sheet of every chemical on the finishing line, so they can confirm none of them is fluorinated.
Expect the brand’s own restricted substances list to be stricter than the law, and to apply to every market they ship to, not only the ones with a ban.
How to switch a finishing line to PFAS-free
- Audit the chemistry. Ask every supplier for a written statement on fluorine content, covering softeners, binders and wetting agents as well as the repellent itself.
- Clean out the old finish. Fluorocarbon residues in pad troughs, mixing tanks, spray lines and stenter frames can contaminate a PFAS-free batch enough to fail a total fluorine test. Flush and clean before the first trial.
- Trial on your own fabric. Run the PFAS-free finish on the constructions you actually ship and check water beading, spray rating and handle against the buyer’s specification.
- Test before you ship. Send finished fabric to an accredited laboratory for total fluorine and keep the report with the order.
- Keep the paperwork together. File supplier declarations, safety data sheets and test reports by order and fabric, so you can answer an audit the same day.
What a PFAS-free finish does well, and where to be straight with buyers
Modern fluorine-free repellents handle water and water-based stains very well. Rain, tea, coffee, juice and wine bead on the surface and lift off with a cloth instead of soaking in, and the fabric keeps its colour, handle and breathability.
Oil is the difference. Fluorocarbons repelled oil as well as water, and no fluorine-free product fully repels oil and grease. Set expectations early: oily stains should be blotted quickly, and an oil repellency grade that a C6 finish reached may not be repeatable. Most brands accept that trade-off, because the alternative is not being able to sell the product at all.
A water-repellent finish is also not waterproofing. It will not seal seams or hold back water under pressure.
Where Nanoman Fabric + Textile fits
Nanoman Fabric + Textile is a PFAS-free water and stain repellent made for exactly this switch. It is supplied as a concentrate in 10 L cans: mixed with 250 L of deionised water, one can makes 260 L ready to use. It is spray-applied, so it fits in after weaving, upholstering or sewing, is touch dry in 1 to 2 hours and reaches full performance in 24 hours. Each litre of ready-to-use coating treats 60 to 80 sq ft, about ₹8 to ₹10 per sq ft.
See the stain test results and application steps on our textile protection page, or order the concentrate direct.
Frequently asked questions
Is a C6 fluorocarbon finish still allowed for export?
For consumer clothing, accessories and footwear sold in the EU, PFHxA, the substance behind C6 chemistry, is restricted from 10 October 2026, and for other textiles from 10 October 2027. France, Denmark and several US states restrict PFAS in clothing as a whole. For most export programmes a C6 finish is no longer a viable option.
What test shows that a fabric is PFAS-free?
Buyers usually ask for a total fluorine or total organic fluorine test on the finished fabric from an accredited laboratory, often against a 50 ppm (50 mg/kg) limit, together with a declaration that no PFAS were intentionally added.
Does a PFAS-free finish repel oil?
Not fully. PFAS-free finishes repel water and water-based stains well, but no fluorine-free product fully repels oil and grease. Oily stains should be blotted quickly.
Can a PFAS-free batch still fail a fluorine test?
Yes, if the finishing line was not cleaned after running fluorocarbon finishes. Flush pad troughs, mixing tanks and spray lines before the first PFAS-free batch.
Do goods already in stock need to comply?
The EU PFHxA restriction does not apply to products placed on the market before its start dates. Other markets have their own transition rules, so check each one with your buyer.
