The toughest US chemical-disclosure law just came due — and most brands only track the bans

The Deadline That Just Turned "Do You Use PFAS?" Into a Filing

On September 15, 2026, the broadest chemical-disclosure obligation in the United States came due. Under Minnesota's Amara's Law, any manufacturer, importer, brand owner, or distributor whose products contain intentionally added PFAS — and are sold, offered for sale, or distributed in Minnesota, including through online sales into the state — had to file a report with the Minnesota Pollution Control Agency describing the product, the PFAS in it, the concentration, and the chemical's function, and pay a filing fee.

Here is the part that makes a state of 5.7 million people a national event: manufacturers do not make Minnesota-specific versions of a cookware line or a jacket. A report filed for Minnesota describes a product sold everywhere. The result is a public database that, in effect, documents intentionally added PFAS across the entire US consumer market — assembled not by a regulator's testing lab, but by manufacturers reporting on themselves.

Reporting Is a Different Animal From a Ban

Most coverage of "forever chemicals" tracks the bans — what can no longer be sold. The 2026 story that caught apparel and textile brands off guard is the parallel wave of reporting rules. A ban tells you what to stop selling. A reporting rule makes you inventory, in writing, to a government agency, everything you already sell that contains the chemical. For a global brand with thousands of SKUs and a multi-tier supply chain, the second is often the harder lift.

What Minnesota actually asks for

Under the PFAS Reporting Information System for Manufacturers (PRISM), a covered manufacturer must report, for each product: a description of the product, the PFAS present, the amount of each (as a concentration or range), the function the PFAS serves, and manufacturer contact information. The obligation attaches to products manufactured after July 1, 2023 — the legislature amended the statute in 2026 to exclude older products from scope. The initial deadline was extended twice, landing on September 15, 2026; manufacturers who applied by August 16 could push their own deadline to December 14, 2026.

Minnesota is not alone

By mid-2026, at least 18 states had enacted class-based PFAS restrictions on consumer products, with roughly 100 new bills introduced in 2026 alone. The obligations differ in ways that matter to a compliance team:

• Washington — reporting requirements for intentionally added PFAS took effect January 1, 2026, covering apparel intended for extreme and extended use, footwear, gear for recreation and travel, cookware, and other categories (Morgan Lewis).
• Maine — after amending its landmark law, Maine now requires reporting only for products granted a Currently Unavoidable Use determination, backed by a notification form and fee; a broad sales ban covering most textiles took effect January 1, 2026. Manufacturers with 100 or fewer employees are exempt from the reporting piece.
• California and New York — took the ban route for textiles and apparel from January 1, 2025; California covers all textile articles, New York is limited to apparel (Morgan Lewis).

The through-line: a brand selling nationally now faces bans in some states and disclosure obligations in others, with different scopes, thresholds, and dates. There is no single federal textile PFAS rule to comply with instead — so the strictest state effectively sets the floor.

Why "Intentionally Added" Is the Trap

The reporting laws turn on the phrase intentionally added PFAS — PFAS added to serve a function in the product (water repellency, stain resistance, a processing aid) rather than present as an unintended trace contaminant. That sounds narrow. In practice, it forces a brand to know something it usually does not: whether any of the finishes, coatings, membranes, or processing aids anywhere in a multi-tier textile supply chain contain a PFAS, and at what level. A durable water-repellent finish, a stain treatment, or a component film can introduce intentionally added PFAS several tiers upstream of the company whose name is on the label — and it is that company that files the report.

The September–October Compliance Cliff

Minnesota's deadline does not arrive in isolation. Three regulatory dates converge inside four weeks, and a brand exporting apparel to both the US and EU is exposed to all three:

1. September 15, 2026 — Minnesota's PRISM disclosure deadline (this article).
2. September 27, 2026 — the EU's Empowering Consumers Directive makes generic "eco-friendly" and self-created sustainability labels illegal, with no transition period. What survives September 27 →
3. October 10, 2026 — EU REACH Annex XVII Entry 79 caps PFHxA and its salts at 25 ppb in consumer textiles and footwear. The PFHxA deadline almost nobody is talking about →

Disclosure (Minnesota), marketing-claim substantiation (EmpCo), and a hard analytical threshold (PFHxA) all land at once. Each one asks the same underlying question in a different accent: what, specifically and verifiably, is in your product?

The Only Answer That Survives a Filing

A reporting regime is unforgiving of vagueness in a way that marketing never was. "We believe our products are PFAS-free" is not a filing; a concentration, a method, and a detection limit is. The brands that can answer are the ones that already treat their supply chain as something to be measured rather than asserted — component-level documentation from suppliers, and independent, instrument-based testing to confirm what the paperwork claims.

"Minnesota's PFAS in Products reporting law establishes the most comprehensive state-level PFAS-in-products compliance framework in the United States."
— Minnesota Pollution Control Agency, PRISM guidance (2026)

That is the practical lesson of the 2026 disclosure wall. Bans can be met by substituting a material. Reporting can only be met by knowing — and proving — what is in the product, tier by tier. The unregulated middle ground, where a brand neither tests nor documents and simply repeats a supplier's assurance, is exactly the ground these laws remove.

What This Means for Manufacturers

The Bottom Line

2026 is the year "forever chemicals" stopped being a marketing debate and became a paperwork obligation. Bans made certain products illegal; reporting made not knowing illegal. A brand can no longer sit in the comfortable middle where it neither tests nor documents. The question every one of these laws asks is the same, and it is now a question you answer to a regulator: not "is your product clean?" but "can you prove, with a number and a method, what is in it?"
