Minnesota has set September 15, 2026, as the deadline for manufacturers to submit reports on products containing intentionally added PFAS that are sold in the state.
The reporting requirement applies to any manufacturer of a product made after July 1, 2023, that is sold, offered for sale, or distributed in Minnesota and contains intentionally added per- and polyfluoroalkyl substances.
The definition of manufacturer under Minnesota’s rules is broad, capturing the entity that produces the product as well as the entity that contracts production under its own brand or label.
Importers and first domestic distributors are also captured under the definition where the original producer or brand owner has no presence in the United States.
Manufacturers seeking more time to comply must ensure their extension requests are postmarked no later than August 16, 2026, which falls on a Sunday this year.
The Minnesota Pollution Control Agency has warned that manufacturers planning to use the US Post Office should be prepared to mail their requests early enough to secure a postmark of August 15, 2026, to avoid missing the deadline.
Extension requests must include a $300 fee submitted in the form of a check, and manufacturers who receive an extension will face a revised reporting deadline of December 14, 2026.
The Minnesota Pollution Control Agency issued guidance on August 7, 2026, through its Daily Digest Bulletin, addressing how manufacturers should navigate the PFAS Reporting Information System for Manufacturers, known as PRISM.
According to the agency, the first user registered under a manufacturer’s account in PRISM will automatically be designated as both the public contact and billing contact for that company.
The MPCA notes that the designated public contact user may reassign those roles to other users registered under the same company within the system, providing some administrative flexibility for larger organisations.
Contact information for each manufacturer’s designated public contact will be treated as public data within PRISM, meaning it will be accessible and visible within the reporting platform.
Manufacturers operating across multiple states should pay close attention to Minnesota’s specific procedural requirements, particularly the payment method and postmarking rules, to avoid inadvertent non-compliance.
