Minnesota PFAS Reporting Rule: What it Means for You

Note: This article has been updated to include information on the April 15, 2026, announcement from the Minnesota Pollution Control Agency that the PFAS reporting deadline for initial reports has been pushed to September 15, 2026. 

On December 8, 2025, Minnesota issued one of the most consequential per- and polyfluoroalkyl substances (PFAS) reporting requirements in the U.S. The Minnesota Pollution Control Agency (MPCA) published its rules in the state register establishing how companies must report PFAS in products under Amara’s Law. 

On April 15, 2026, the MPCA announced that the deadline for initial PFAS reports would be September 15, 2026, pushing the deadline back from July 1, 2026. Subsequent annual PFAS reports will be due on February 1 of each year. The MPCA has provided more details on a dedicated Reporting PFAS in Products webpage.

This latest update clarifies obligations around impending deadlines. Now, manufacturers selling into the state must take immediate action to prepare PFAS reports and identify PFAS in their supply chains. While many states are advancing new PFAS regulations, Minnesota’s approach stands out because of its 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. For more information on PRISM, read the MCPA’s Reporting PFAS in Products webpage or its supplemental reporting guide.

Minnesota’s PFAS Reporting Rule: What to Know In 2026

Minnesota’s 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 launched 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 PFAS reporting 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.

Minnesota’s 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.
• September 15, 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 Is a Milestone Year for PFAS Reporting

Several other states have PFAS reporting obligations taking effect in the next few years, including Maine, Connecticut, Washington, and New Mexico. States will also likely react to the April 13, 2026, update to  the Toxic Substances Control Act (TSCA) that seems to give clear indication that the Environmental Protection Agency will remove imported articles from the scope of reporting. 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. And that means companies need to start thinking ahead and preparing now. 

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

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 delay 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 reporting 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 September 15, 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 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.
