ZDHC tightens rules on forever chemicals in textiles

PFAS are the invisible finish that can make a trench repel rain or a sneaker upper shrug off a stain, but ZDHC is now saying they have “no place” in standard textile, apparel, footwear and leather manufacturing. The group’s latest push is less about lofty sustainability language than about forcing cleaner chemistry, tighter testing and better proof across the supply chain.

ZDHC said its immediate focus is to eliminate intentionally used PFAS in manufacturing inputs while it works through the harder problems of detection, trace presence and practical implementation. The organization is also pushing clearer direction on PFAS risks in chemical formulations, information communication and day-to-day factory use, a sign that the conversation has moved from broad concern to formal chemical-control requirements.

That matters because the rulebook around the market is already getting sharper. France’s PFAS restrictions on selected consumer products, including textiles and footwear, took effect on 1 January 2026, and several U.S. state PFAS laws affecting products, including textile-related restrictions, also went into effect the same day. For brands leaning on generic “PFAS-free” claims, that leaves less room for vague promises and more pressure to show exactly what is in the bath, on the line and in the finished goods.

ZDHC plans a more comprehensive PFAS communication for publication in October 2026, alongside updates to its MRSL, the restricted substances list that the group describes as a living document. That framework is meant to be updated through independent experts, industry stakeholders and scientific advisors, and ZDHC says its network now covers more than 12,000 manufacturing sites worldwide through independently verified facility-level data. The same system runs through ZDHC Gateway, where chemical inventory conformance and wastewater reporting are tracked, making PFAS compliance a matter of measurable controls rather than mood music about responsibility.

The practical test is where the weakest links will show. Suppliers selling water, oil and stain-resistant finishes are the most exposed, especially where older performance recipes still depend on fluorinated chemistry. ZDHC’s harder line gives brands fewer excuses to keep PFAS in circulation, and it places the burden on mills, chemical formulators and testing teams to prove they can deliver performance without the chemistry that regulators are now closing in on.
