Key takeaway
What This Development Means
Minnesota PFAS product reports are generally due 15 September 2026. Approved extensions run to 14 December, while denied applicants receive 30 days after denial or until 15 September, whichever is later. Manufacturers must document supplier due diligence.
Does a pending extension application suspend the 15 September deadline?
The agency will keep processing timely applications after 15 September, but approval is not automatic. Approved applicants receive until 14 December. If denied, the applicant receives 30 days after denial or until 15 September, whichever is later.
Can a manufacturer report an unknown PFAS concentration?
The guidance allows specified unknown values based on best available information, but manufacturers must conduct and document supplier due diligence. They should retain relevant records for five years and cannot rely only on a supplier’s refusal to disclose formulation details.
Source basis: Minnesota Pollution Control Agency, Reporting PFAS in products (updated 21 August 2026)
The Minnesota Pollution Control Agency materially updated its per- and polyfluoroalkyl substances product-reporting guidance on 21 August 2026, clarifying what happens when extension applications remain pending or are denied. The binding initial deadline remains 15 September, affecting manufacturers, importers, brands and reporting agents whose intentionally added PFAS products are sold or distributed in Minnesota.
Minnesota PFAS Reporting Extension Decisions May Arrive After The Deadline
The agency says it will continue processing extension applications after 15 September. Applications had to be postmarked by 16 August. An approved applicant receives a reporting deadline of 14 December 2026.
If an application is denied, the manufacturer must report within 30 days after the denial date or by 15 September, whichever is later. That clarification prevents a pending decision from silently eliminating the opportunity to file, but it does not grant an automatic extension to every applicant.
Manufacturers seeking a waiver from reporting particular information must submit the request by 14 November. The agency advises that a manufacturer should first obtain an extension because waiver processing may continue beyond the initial deadline. Annual updates are due each 1 February after the initial report.
Scope, Fees And Evidence Expectations Remain Unchanged
The requirement covers products containing intentionally added PFAS that are sold, offered for sale, distributed or offered for promotional purposes in Minnesota, including online sales. Products manufactured before 1 July 2023 are excluded from the initial reporting requirement.
The one-time manufacturer fee remains $800. Reporters may use best available information and specified “unknown” values where exact data cannot be obtained, but the agency expects due diligence. Manufacturers should contact suppliers, document their efforts and retain supporting records for five years. A contractual statement that a supplier will not disclose a formulation does not remove the manufacturer’s reporting responsibility.
The update does not alter Minnesota’s separate product-category prohibitions already in force or the broader 2032 framework for intentionally added PFAS.
What Product Businesses Should Do Now
Manufacturers should confirm whether an extension application was timely postmarked, record its status and create a filing plan for each possible decision. Product and component data should be reconciled to stock-keeping units, chemical identities, concentration ranges and supplier evidence before submission through the PFAS Reporting Information System for Minnesota, known as PRISM.
Analysis: the denial rule turns extension status into a governance issue rather than a simple calendar change. A central team needs visibility over pending applications, while product owners need filing-ready data in case a 30-day clock begins. This is an inference from the agency’s sequencing and the statutory reporting duty.
Retailers and online sellers should identify manufacturers responsible for reports and address gaps where imported or own-brand products lack a responsive reporting entity.
