Several concrete PFAS reporting and compliance dates remain on the calendar through 2027, led by Minnesota and New Mexico’s remaining 2026 deadlines and a wave of new prohibitions and reporting obligations taking effect throughout 2027 in New Hampshire, New Mexico, Rhode Island, Vermont, Utah, and Washington. Product compliance teams should prioritize the actions below now to avoid missing a filing, labeling, or reporting deadline.

PFAS regulation in the United States continued to develop rapidly throughout 2026, with federal and state activity moving beyond broad policy initiatives toward more detailed reporting, labeling, and product-specific requirements. This checklist is adapted from Adherent’s whitepaper, “PFAS: United States Key Regulatory Developments – 2026 Update” (published July 22, 2026), and pulls every dated obligation from that analysis into one reference so compliance calendars don’t miss a filing window. The dates below are current as of that publication; further regulatory developments may have occurred after that date, so treat this as a planning checklist rather than a final legal determination.

Unlike a single-state deep dive, this piece deliberately spans both state and federal obligations, because product compliance teams rarely have the luxury of tracking only one jurisdiction at a time. A product sold nationally can be in scope for a Minnesota reporting deadline, a New Mexico labeling rule, and a pending federal TSCA filing window all at once, each running on its own clock and its own definitions of “intentionally added PFAS.” 

Adherent’s PFAS regulatory hub keeps a continuously updated view of this same landscape between whitepaper refreshes, so this checklist can be treated as a snapshot rather than the final word.

Remaining 2026 Deadlines

Minnesota: Restrictions on PFAS, Lead, and Cadmium in Products, and Food Package Labeling (House File 2310)

• August 16, 2026: Requests for reporting extensions and waivers.
• September 15, 2026: Initial PFAS-in-products reports due.
• November 14, 2026: Requests for waivers from manufacturers that previously received a reporting extension must be postmarked or mailed by this date.
• December 14, 2026: Reports due for manufacturers with extensions.

Minnesota’s reporting framework under Amara’s Law is one of the most closely watched in the country. For the full mechanics behind these dates, including the PRISM reporting system, see Adherent’s dedicated article PFAS Pressure Is Rising: Is Your Product Portfolio Ready for Minnesota?

New Mexico: Toxic PFAS in Consumer Products (NMAC 20.13.2)

• No later than October 31, 2026: Deadline for currently unavoidable use proposals relating to sales prohibitions effective January 1, 2027.
• October 31, 2026: Complete label waiver requests received by this date qualify for deemed-approved treatment while under agency review.
• At least 30 days before the applicable reporting due date: Reporting waiver and reporting extension requests must be submitted.

2027 Deadlines to Prepare For Now

• Minnesota – February 1 each year: Annual updates are due when required.
• New Hampshire – January 1, 2027: PFAS-added carpets and rugs, cosmetics, textile treatments, feminine hygiene products, food packaging and containers, juvenile products, upholstered furniture, and textile furnishings are prohibited (House Bill 1649).
• New Mexico – January 1, 2027: Initial manufacturer reports are due, PFAS labeling begins for covered products manufactured after this date, and sales prohibitions begin for cookware, food packaging, dental floss, juvenile products, and firefighting foam containing intentionally added PFAS.
• Rhode Island – January 1, 2027: The prohibition on covered products containing intentionally added PFAS begins, and the amended enforcement penalties become operative.
• Vermont – July 1, 2027: PFAS prohibitions begin for cleaning products and dental floss, and covered products may not be sold in fluorine-treated containers.
• Utah – December 1, 2027: Menstrual products manufactured on or after this date must disclose intentionally added ingredients; PFAS is expressly included in the covered chemical definition.
• Washington – January 1, 2027: The manufacture, sale, or distribution of covered apparel and accessories, automotive washes, and cleaning products containing intentionally added PFAS is prohibited.
• Washington – January 31, 2027: Manufacturers must submit first reports for covered consumer-product categories containing intentionally added PFAS manufactured on or after January 1, 2026; reports are due annually thereafter.
• Federal TSCA Section 8(a)(7) – on or before January 31, 2027: PFAS reporting is set to begin on this date, or 60 days after the effective date of the EPA’s forthcoming final revisions, whichever occurs first. Because the EPA’s final rule is still pending as of this whitepaper, there is currently no fixed calendar filing deadline.

Four states, New Hampshire, New Mexico, Rhode Island, and Washington, reach major PFAS product compliance milestones on January 1, 2027, with additional state deadlines following throughout the year. Teams managing PFAS reporting across borders, not just across US states, may also find Adherent’s guide Forever Chemicals, Finite Timelines: Managing PFAS Reporting and Compliance Across Borders useful for building out that wider picture, and the State-by-State Comparison guide for the full domestic detail behind each date above.

Priority Actions for the Rest of 2026

Adherent’s whitepaper identifies five priority considerations for product compliance teams for the remainder of 2026:

• Advancing Minnesota reporting preparations in line with the August, September, and December milestones.
• Reviewing New Mexico reporting, labeling, and petition requirements ahead of the October 31, 2026 and January 1, 2027 dates.
• Preparing Washington reporting files for the first submissions due January 31, 2027.
• Continuing to collect relevant historical TSCA data while monitoring the EPA’s final scope revisions and reporting timeline.
• Developing supporting documentation for exemptions and currently unavoidable use requests before the relevant submission windows approach.

State activity in 2026 was immediate and varied, including newly enacted restrictions affecting cosmetics and consumer products, amendments to existing PFAS frameworks, and new implementation rules. Tracking that many moving deadlines across federal and state authorities by hand is time-consuming, and the cost of missing one is rarely just a missed date: late or incomplete PFAS filings can mean lost market access in that state until the paperwork catches up. That risk compounds for companies selling across multiple states, since a single product line can be subject to several of the reporting, labeling, and prohibition deadlines above at the same time, each with its own documentation trail.

Adherent’s agentic AI product compliance platform continuously monitors these regulatory sources and prioritizes changes by deadline risk and business impact, so your team can act on what matters most before a filing window closes.

Frequently Asked Questions

What PFAS deadlines are still ahead in 2026?

Minnesota has remaining PFAS-in-products reporting deadlines on September 15, November 14, and December 14, 2026. New Mexico has an October 31, 2026 deadline for currently unavoidable use proposals and qualifying label waiver requests.

What major PFAS deadlines take effect on January 1, 2027?

New Hampshire, New Mexico, Rhode Island, and Washington have major PFAS-related product compliance requirements beginning January 1, 2027, covering products such as cookware, cosmetics, textiles, juvenile products, apparel, and cleaning products.

When does federal TSCA PFAS reporting begin?

Reporting under TSCA Section 8(a)(7) is set to begin January 31, 2027, or 60 days after the effective date of the EPA’s forthcoming final revisions, whichever occurs first. Because the EPA’s final rule is still pending, there is currently no fixed calendar filing deadline.

What should compliance teams prioritize before the end of 2026?

Five priorities stand out: preparing Minnesota reporting ahead of its 2026 milestones, reviewing New Mexico’s requirements ahead of its October 31, 2026 and January 1, 2027 dates, preparing Washington’s first reporting submissions due January 31, 2027, continuing to collect historical TSCA data while monitoring the EPA’s timeline, and developing documentation to support exemption and currently-unavoidable-use requests.

Why do so many PFAS deadlines cluster around January 1, 2027?

Four states, New Hampshire, New Mexico, Rhode Island, and Washington reach major PFAS product compliance milestones on January 1, 2027, with additional state deadlines following throughout the year. The federal TSCA Section 8(a)(7) reporting period is also set to begin no later than January 31, 2027, unless triggered earlier by EPA’s final revisions. The practical effect is a significant compliance period at the turn of the year, making advance preparation important for product compliance teams affected.
