Federal Court Blocks New Mexico’s PFAS Product Labeling Law
A court grants a preliminary injunction stopping New Mexico’s PFAS labeling law enforcement.
Why it matters: The ruling sets a key precedent on state chemical labeling regulations, influencing how corporations comply with environmental laws nationwide. It challenges the constitutionality of state mandates that compel manufacturer disclosures.
- Judge Margaret I. Strickland halted New Mexico’s PFAS labeling rule on September 16, 2026.
- The law requires products with intentionally added PFAS to display a 'PFAS' Erlenmeyer flask icon starting January 1, 2027.
- Industry groups, including the American Chemistry Council, sued July 1, 2026, arguing the rule violates the First Amendment.
- The regulation phases in PFAS prohibitions on consumer goods through 2032 under New Mexico’s PFAS Protection Act.
On September 16, 2026, U.S. District Judge Margaret I. Strickland issued a preliminary injunction blocking New Mexico’s requirement that consumer products containing intentionally added per- and polyfluoroalkyl substances (PFAS) must bear a special label. This stops the enforcement of the labeling rule, originally set to begin January 1, 2027.
The labeling mandate derives from New Mexico’s Per- and Poly-Fluoroalkyl Substances Protection Act (HB 212), enacted in April 2025 and finalized with rules in May 2026. The law requires products containing intentionally added PFAS to display an Erlenmeyer flask icon labeled “PFAS.” It also sets phased prohibitions on PFAS in various goods, starting with cookware, food packaging, and juvenile products in 2027, extending to carpets and cosmetics in 2028, and culminating in a near-complete ban by 2032.
The legal challenge was led by a coalition of industry associations including the American Chemistry Council and the National Association of Manufacturers. They filed suit on July 1, 2026, arguing the labeling requirement violates the First Amendment by compelling manufacturers to communicate a government message they claim is neither purely factual nor noncontroversial.
Linda Kelly, Chief Legal Officer of the National Association of Manufacturers, welcomed the ruling saying, “Manufacturers welcome the District of New Mexico’s decision blocking this unlawful labeling mandate from taking effect.”
This injunction represents a significant moment in the ongoing legal debates over state chemical regulations and labeling laws. It raises questions about the balance between public health goals and constitutional protections, with broad implications for businesses facing multiple, sometimes conflicting, state-level environmental mandates.
By the numbers:
- January 1, 2027 — Start date for PFAS labeling and initial prohibitions on cookware, food packaging, juvenile products, and firefighting foam.
- January 1, 2028 — Prohibition extends to carpets, rugs, and cosmetics containing PFAS.
- January 1, 2032 — Near-complete ban on PFAS in consumer products, except those deemed 'Currently Unavoidable Use'.
Yes, but: The injunction is preliminary, so future rulings could reinstate the law or modify its provisions after detailed legal review.
What's next: The court will continue reviewing the lawsuit, potentially setting a timeline for a full hearing on the constitutionality of New Mexico’s PFAS labeling mandate.
