If your company received a 90-day extension under Minnesota’s PFAS in products law, your Minnesota PFAS reporting deadline is now December 14, 2026. This is the final date to submit your initial report through the state’s PRISM system. There is no second extension available, and the extension you already received was a one-time allowance under the adopted rules.
This guide is written for manufacturers, importers, and compliance teams that already filed an approved extension request and now need to complete their reporting before the December 14 cutoff. It covers exactly what must be submitted, the fee, the 2026 scope change, and how to close supplier-data gaps in the time remaining. For the full step-by-step filing walkthrough, see Certivo’s complete PRISM filing guide for 2026.
If you are still assessing exposure across your portfolio, a compliance risk assessment can help you see which products and suppliers carry open PFAS data gaps before the deadline.
Key Takeaways
⏳ The final Minnesota PFAS reporting deadline for approved extension filers is December 14, 2026 — a one-time 90-day extension with no further延期 available.
📌 Reporting is required under Amara’s Law (Minn. Stat. § 116.943) for products with intentionally added PFAS sold, offered for sale, or distributed in Minnesota.
📊 Reports are filed through PRISM and must include product description, PFAS chemical identity (CASRN where available), concentration range, and function, plus a flat $800 reporting fee per manufacturer.
🏭 A May 2026 amendment narrowed scope: only products manufactured after July 1, 2023 must be reported.
🔗 Supplier data collection across multi-tier supply chains remains the main bottleneck to filing a complete report on time.
📄 MPCA has indicated a manufacturer can be considered compliant if it reports all available information, retains due-diligence documentation, and provides a plan to obtain outstanding data.
What the December 14 Deadline Means for Extension Filers
The December 14, 2026 date applies only to manufacturers whose extension request and fee were postmarked by August 16, 2026 and subsequently approved by the Minnesota Pollution Control Agency (MPCA). The adopted rules limit manufacturers to a single extension of the reporting deadline, so this is a firm, final date rather than a rolling one.
Approved filers should treat December 14 as a hard operational target. The initial report must be submitted through the PFAS Reporting and Information System for Manufacturers (PRISM), and the flat reporting fee must accompany that submission. Certivo’s overview of state PFAS regulations in 2026 explains how Minnesota fits into the wider US state landscape.
For context on how the obligation was originally structured, Certivo’s Amara’s Law explainer covers the baseline requirements that still apply to every filer.
How the Minnesota PFAS Reporting Deadline Reached December 14
The initial reporting date has moved three times. Understanding the sequence helps teams confirm which deadline applies to them and avoid acting on an outdated date.
Date | Status | What it means |
|---|---|---|
January 1, 2026 | Original deadline | First date set when the reporting and fees rule was adopted (Dec. 8, 2025) |
July 1, 2026 | First extension | Announced in 2025 to give suppliers and manufacturers more time |
September 15, 2026 | Second extension | Announced April 15, 2026 in response to PRISM and supply-chain data challenges |
December 14, 2026 | Extension filers only | Final deadline for manufacturers granted the one-time 90-day extension |
Each delay reflected the same underlying difficulty: assembling substance-level PFAS data across complex, multi-tier supply chains. According to the MPCA, the agency expects more than 5,000 manufacturers to report, underscoring the scale of the obligation. The pattern of extensions is a signal that manufacturers should not expect further relief, which makes finishing before December 14 the only safe assumption.

What You Must Report in PRISM Before December 14
The content requirements are the same for extension filers as for all other manufacturers. Each report submitted through PRISM must identify the product or component and describe the PFAS it contains. Based on the MPCA’s adopted rule, a complete submission includes the following elements.
Required reporting elements
✓ Product or product-category description for each item containing intentionally added PFAS
✓ PFAS chemical identity, including the chemical name and CASRN or other identifying number where available
✓ Concentration, reported within defined ranges rather than exact values
✓ Function or purpose the PFAS serves in the product or component
✓ Manufacturer and contact information, plus authorized-representative details where applicable
A flat $800 reporting fee accompanies the initial report, regardless of how many products are included. This is separate from the extension request fee that approved filers already paid. Reports are reviewed by MPCA staff and, apart from protected trade-secret data, become publicly accessible in PRISM, so accuracy and consistency matter for reputational as well as regulatory reasons.
Manufacturers managing large catalogs often struggle to connect substance data to specific parts. Linking declarations to the bill of materials is what turns scattered supplier inputs into a defensible, product-level report. Certivo’s broader PFAS framework page outlines how substance-level tracking supports this across jurisdictions.
The 2026 Amendment: Only Products Made After July 1, 2023
A meaningful scope change took effect in 2026. The MPCA announced on May 28, 2026 that Governor Walz had signed legislation amending the reporting requirement so that it applies only to products manufactured after July 1, 2023. Previously, products had to be reported regardless of manufacture date.
For extension filers, this change can reduce reporting volume. Replacement parts and legacy items produced before July 1, 2023 but still offered for sale no longer trigger a reporting obligation, even if they contain intentionally added PFAS. Confirm this cutoff against your product records before finalizing, and document the basis for any item you exclude. The official MPCA reporting page reflects the current scope.
Why Supplier Data Is the Real Bottleneck
The reporting fields look straightforward, but the difficulty lies in sourcing accurate PFAS data from suppliers. A single finished product can contain components from multiple tiers, and PFAS may be present in coatings, seals, lubricants, membranes, or electronic parts that the brand owner never specified directly.
Manual collection through spreadsheets and email does not scale when hundreds of suppliers and thousands of parts are involved. Teams that have moved to automated supplier data collection and structured portals recover far more usable data in less time. Certivo’s analysis of multi-tier PFAS compliance shows why visibility beyond Tier 1 is essential for a complete report.
Importantly, MPCA has indicated that a manufacturer can be considered compliant if it timely reports all available PFAS information, retains its due-diligence documentation, and provides a plan to obtain outstanding data. This means a good-faith, well-documented submission is better than a missed deadline. Keeping an auditable record of supplier outreach is central to staying audit-ready if the agency later asks how the data was gathered.
What Happens If You Miss the December 14 Deadline
Because the extension is one-time only, a missed December 14 submission leaves a manufacturer out of compliance with the adopted reporting rule under Amara’s Law. The practical exposures are worth stating plainly for leadership.
Exposure | Why it matters |
|---|---|
⚠️ Regulatory non-compliance | The reporting obligation is mandatory under Minn. Stat. § 116.943; no further extension exists |
⚠️ Market-access risk | Continuing to sell unreported PFAS-containing products in Minnesota raises enforcement and future-ban exposure |
📄 Evidence gaps | Without documented due diligence, demonstrating good-faith effort becomes harder |
🔗 Customer and ESG scrutiny | Public PRISM disclosure means customers and stakeholders can see who reported and who did not |
The strategic point for CEOs, CFOs, and compliance leaders is that Minnesota is a precedent-setting state program. Reporting cleanly here builds the data foundation needed for other emerging state and federal PFAS obligations, which Certivo tracks in its 2025–2026 PFAS master guide.
Pre-December 14 Compliance Checklist
Use this checklist to confirm readiness in the weeks before the deadline.
✓ Confirm your deadline — verify your extension was approved and that December 14, 2026 applies to your filing.
✓ Apply the July 1, 2023 scope cutoff — exclude pre-cutoff products and document the basis.
✓ Finalize your product list — identify every in-scope product or component with intentionally added PFAS.
✓ Close supplier-data gaps — escalate outstanding requests and record all outreach for due-diligence evidence.
✓ Map substances to concentration ranges — ensure each PFAS has an identity, range, and function.
✓ Prepare the $800 fee — confirm payment will accompany the initial report.
✓ Review trade-secret claims — flag any data requiring protection before public disclosure.
✓ Submit in PRISM early — avoid last-day system timeouts and allow buffer for corrections.

How AI-Native Compliance Automation Helps You File on Time
With limited time before December 14, the constraint is rarely the PRISM form itself. It is assembling, validating, and mapping supplier data fast enough to produce a complete, accurate report. This is where AI-native compliance automation changes the timeline.
Certivo acts as the system of record for product compliance, while CORA provides the embedded intelligence layer. CORA-powered regulatory intelligence helps teams parse supplier documents, extract PFAS identities and concentrations, and validate certificates at scale rather than manually re-keying data. Automated supplier portals reduce the back-and-forth that slows collection, and BOM-level mapping links every declaration to the right product.
For article importers and manufacturers with large portfolios, Certivo’s approach to PFAS supplier data collection at scale shows how continuous, audit-ready documentation replaces reactive, deadline-driven scrambles. The goal is not to eliminate compliance risk, but to reduce surprises, speed evidence retrieval, and give leadership clear visibility into reporting status before the deadline.
What this means after December 14
Minnesota reporting does not end with the initial filing. Subsequent reports are due annually on February 1, and reports should be updated as new information becomes available. Looking further ahead, a broad prohibition on products with intentionally added PFAS takes effect January 1, 2032 unless the MPCA designates a specific use as a currently unavoidable use (CUU) through separate rulemaking. Building a durable, centralized compliance data backbone now positions your organization for that continuous cycle rather than another one-time push.
