Since October 10, the European Union has banned undecafluorohexanoic acid (PFHxA), its salts and related substances above strict concentration limits in clothing, footwear, accessories, textiles, leather, furs and hides sold to the general public. The same restriction covers cosmetic products and paper and cardboard food containers. For sourcing teams, the ban is no longer a compliance horizon item — it's live law with a per-material testing burden attached.

What are the new PFHxA limits?

The restriction sets two thresholds, and both apply to each homogeneous material in a product, not the finished article as a whole:

• 25 parts per billion for the sum of PFHxA and its salts
• 1,000 ppb for the sum of PFHxA-related substances

The per-material framing is what makes this demanding for suppliers. A jacket, for instance, isn't treated as one material under the rule — its outer shell fabric, waterproof membrane, durable water repellent finish and lining must each pass testing separately. That explainer comes from Naomie Halioua, co-founder and chief data officer of Cleo, an AI platform for product compliance.

For mills and finishers, that means certifications on a coated laminate won't cover the trims or lining sourced elsewhere in the tier. Every component needs its own traceable test result.

Why does this chemical matter?

PFHxA belongs to the per- and polyfluoroalkyl substances (PFAS) family, the man-made compounds known as "forever chemicals" because they can take thousands of years to break down. In apparel, PFHxA has served as a stain-resistance treatment — and, critically, as the substitute compound brands turned to after the EU banned an earlier PFAS chemical.

That substitution loop is now closed. The US Environmental Protection Agency flagged the risk in a 2023 toxicological review, which found evidence suggesting PFHxA can harm the liver "given sufficient exposure conditions." The EU has now removed it from the menu of acceptable alternatives.

Where does the ban come from?

The European Commission passed the restriction in 2024 by amending the 2006 law known as REACH — the Registration, Evaluation, Authorisation and Restriction of Chemicals regulation — after a two-year transition period that has now expired.

The move reflects the EU's targeted approach to PFAS restriction rather than a single sweeping measure. Some member states have gone further on their own: Denmark and France have already implemented broader PFAS bans, creating a patchwork that exporters to Europe must track market by market.

What's next on the calendar?

More scope arrives next year, when a further ban as scheduled extends the restrictions to textiles outside the clothing category — bed linen, curtains and carpets among them. Home textile suppliers who assumed the rules applied only to apparel have a shrinking window to reformulate or re-source finishes.

What should sourcing teams do now?

The commercial decision this forces is straightforward: brands selling into the EU need chemical-property documentation at the component level, sitting alongside the origin tracing and end-of-life obligations already taking shape under other EU rules. Product compliance is no longer about where a garment was made or what happens when it's discarded — it now extends to its chemical composition, material by material.

Suppliers of DWR finishes, membranes and stain-resistant treatments should expect buyers to request PFHxA test reports per homogeneous material before orders are confirmed. Mills that can't produce them will likely lose placements to those that can — and with the non-apparel textile ban landing next year, the same pressure is about to reach home goods suppliers too.
