New Minnesota PFAS Reporting Rule: What it Means for You

On December 8, 2025, Minnesota finalized one of the most consequential per- and polyfluoroalkyl substances (PFAS) reporting requirements in the U.S. The Minnesota Pollution Control Agency (MPCA) issued its final rules in the state register establishing how companies must report PFAS in products under Amara’s Law. The update introduces a new reporting system, clarified obligations, and firm deadlines, creating real urgency for teams responsible for PFAS compliance. Manufacturers selling into the state need to start preparing now by identifying PFAS in their supply chains and parts. MPCA has provided more details in a dedicated Reporting PFAS in Products webpage.

While many states are advancing new PFAS regulations, Minnesota’s approach stands out because of its aggressive reporting timeline, product scope, and the release of a new reporting platform called PFAS Reporting and Information System for Manufacturers (PRISM) that is designed to support rapid multi-state adoption. 

This article outlines why the first six months of 2026 will be some of the busiest yet for PFAS regulatory compliance.

Minnesota’s PFAS Reporting Rule: What’s New for 2026

Minnesota’s final rule confirms that manufacturers must report all products that contain PFAS sold, offered, or distributed in the state, including online sales. The reporting obligations apply broadly and include fluoropolymers such as polytetrafluoroethylene (PTFE) meaning that most manufacturers selling into Minnesota will have at least some in-scope items. This is a significant point of concern for businesses with limited supply chain visibility or complex supplier networks.

To streamline compliance and manage the large volume of expected submissions, the MPCA has created the  PRISM platform. The system is scheduled to launch in January 2026 and is designed to serve as the centralized system for gathering Minnesota’s PFAS data going forward.

Minnesota’s fee structure is straightforward: Reporters must pay a one-time fee of $800 per manufacturer, not per product.

The final rule also clarifies how companies should report PFAS in products, providing flexibility around:

• Reporting concentration ranges
• Grouping similar products
• Establishing supply-chain reporting partnerships
• Applying for waivers, extensions, or trade-secret protections

Minnesota’s PFAS reporting rule is designed to increase market transparency, and the PRISM system reflects that intent. Most of the information manufacturers submit will be made publicly accessible, including product details, PFAS functions, and concentration ranges. While the rule allows companies to apply for trade-secret protection, these requests must meet strict criteria, and approval is not guaranteed.

A Tight PFAS Reporting Timeline

Minnesota has established some key dates that will define 2026 compliance planning:

• January 2026: PRISM becomes available for manufacturers to register and begin preparing reports.
• July 1, 2026: Initial PFAS reports are due. This date sets a six-month extension from the original January deadline, but it’s still a challenging timeline for companies that haven’t already started engaging suppliers for PFAS data. 
• February 2027 and beyond: After the initial filing, manufacturers do not need to re-report annually unless a product changes. However, all new products introduced to the Minnesota market must be reported by February 1 each year going forward. This ongoing requirement reinforces the need for a scalable, repeatable PFAS reporting process.

Why 2026 Will Be a Milestone year for PFAS Reporting

2026 will be a turning point for PFAS reporting across the U.S.

Several other states have PFAS reporting obligations taking effect between 2025 and 2027, including Maine, Connecticut, Washington, and New Mexico. States will also likely react to the probable narrowing scope of the Toxic Substances Control Act (TSCA) section 8(a)(7) reporting obligation for article importers, as outlined in the November proposed amendment. As federal PFAS regulations continue to move slowly, states are able to legislate quickly with less procedural red tape.

Minnesota’s PRISM system is intentionally built so that other states can adopt it. This means Minnesota has now enabled other states to quickly roll out their own final reporting rules. 

State-level reporting initiatives are accelerating. For more information on current PFAS reporting by state and PFAS bans by state, check out our article.

Companies that do business across the U.S. should prepare for a patchwork of overlapping and diverging PFAS reporting requirements, increasing the burden on compliance teams. Companies that wait until 2026 to begin collecting PFAS data will struggle not only with Minnesota’s deadline, but also with the next wave of state-level reporting mandates.

What Manufacturers Should Do Now

In the final rule, MPCA specifically states that manufacturers should “request detailed disclosure of information… from their supply chain until all required information is known.” Automating the data collection process at the part level, and implementing tools to review a product bill of material (BOM), will be the fastest way to comply with both Minnesota and other upcoming state reporting requirements, as well as to provide information to retailers, distributors, and customers. 

Given Minnesota’s aggressive timeline, manufacturers should begin PFAS due diligence now:

1. Identify all products sold into Minnesota and evaluate which are likely to contain intentionally added PFAS
2. Engage suppliers early to confirm PFAS usage and collect declarations
3. Prepare internal documentation to meet the July 1, 2026 deadline
4. Familiarize yourself with PRISM
5. Establish an ongoing PFAS identification program, not just a one-time reporting effort

As companies prepare for Minnesota’s July 1, 2026 PFAS reporting deadline and the broader wave of state-level reporting mandates, it is clear that manual or one-off tracking methods will not be enough. Organizations need a scalable way to identify PFAS across complex supplier networks, manage reporting obligations, and maintain defensible documentation as regulations evolve.

Assent’s PFAS reporting software helps manufacturers automate supplier PFAS engagement using AI-powered workflows combined with our expansive network of supply chain data. We’re the only solution that can get your PFAS program up and running in a matter of weeks, which is the speed you need to meet the latest PFAS reporting deadline.
