New Hampshire will prohibit the sale of listed consumer products containing intentionally added PFAS beginning January 1, 2027. The New Hampshire Department of Environmental Services (NHDES) has finalized its PFAS Products Control Program rule (Env-Sw 2300), the implementing framework for RSA 149-M:64. For any manufacturer, importer, or distributor selling into New Hampshire, the practical work starts now: screen bills of materials against the banned categories, stage supplier PFAS data, and build a process to answer a Certificate of Compliance request within 30 days.
This guide explains what the New Hampshire PFAS product ban covers, how PFAS is defined under state law, the Certificate of Compliance obligation, exemptions, enforcement exposure, and the supply-chain data work required before the deadline.

Key Takeaways
📌 New Hampshire prohibits intentionally added PFAS in listed consumer product categories from January 1, 2027 under RSA 149-M:64 (HB 1649, as amended by HB 167).
⚠️ Manufacturers and suppliers must respond to an NHDES Certificate of Compliance request within 30 days, certifying products as non-PFAS or identifying a valid exemption.
📊 New Hampshire defines PFAS using the narrower federal TSCA structural definition, not the broad total-organofluorine class definition used by Maine and Minnesota.
🏭 Affected categories include carpets/rugs, cosmetics, textile treatments, feminine hygiene products, food packaging, juvenile products, upholstered furniture, textile furnishings, and certain sport/board waxes.
📄 Even exempt products require a Certificate of Compliance stating the basis for the exemption; certificates must be updated on reformulation.
🔗 Compliance is a multi-tier supplier data problem: the ban applies at the finished-product level but the evidence lives deep in the supply chain.
What the New Hampshire PFAS Product Ban Requires
RSA 149-M:64 prohibits offering for final sale, use, or promotional distribution in New Hampshire any listed consumer product that contains intentionally added PFAS, starting January 1, 2027. "Intentionally added PFAS" means PFAS a manufacturer has added to a product or component for a functional or technical effect, including intentional breakdown products.
The obligation is a market-access restriction. If a covered product contains intentionally added PFAS and no exemption applies, it cannot be sold or distributed into the state after the deadline. This mirrors the structure of other state PFAS bans and reinforces why manufacturers now treat PFAS as a portfolio-wide issue rather than a category-specific one. Certivo's state PFAS regulations guide tracks how these state frameworks interact.
How New Hampshire Defines PFAS (This Scoping Detail Matters)
New Hampshire's definition is narrower than several other states, and getting this wrong leads to over-scoping or under-scoping BOMs. Rather than banning any substance with a single fully fluorinated carbon (the broad approach in Maine and Minnesota), RSA 149-M:64 ties its PFAS definition to the federal TSCA structural definition.
Under the state law, PFAS refers to substances defined at 40 CFR 705.3 that contain at least one of three specified substructures. This aligns New Hampshire with the EPA TSCA reporting definition used for the federal PFAS reporting rule.
The practical consequence: a substance regulated as PFAS in Minnesota may fall outside New Hampshire's structural definition, and vice versa. Manufacturers managing PFAS tracking across US and EU jurisdictions need substance-level logic that applies each jurisdiction's definition correctly rather than a single blanket rule.
Definition Approach | Example States | Scope |
|---|---|---|
TSCA structural definition (three substructures) | New Hampshire | Narrower |
Total-organofluorine / "at least one fully fluorinated carbon" | Maine, Minnesota | Broader |
Which Products and Industries Are Affected
The ban applies to specific consumer product categories. The current scope reflects HB 1649 (2024) plus the wax categories added by HB 167 (2025).
Product Category | Notes |
|---|---|
Carpets or rugs | Fabric floor coverings, including indoor door mats |
Cosmetics | Retail and professional-use products applied to the body |
Textile treatments | Substances applied to fabrics (stain/water resistance) |
Feminine hygiene products | Tampons, pads, cups, period underwear, applicators |
Food packaging and containers | Broad definition including wraps, trays, coatings, inks, labels |
Juvenile products | Designed or marketed for children under 12 |
Upholstered furniture | Indoor upholstered furniture |
Textile furnishings | Draperies, bedding, towels, tablecloths, floor coverings |
Waxes | For boats, skis, surfboards, bodyboards, or skimboards (HB 167) |
Affected sectors span textiles and furnishings, consumer and personal care, food and packaging, juvenile products, and sporting goods. Brands in consumer goods and electronics manufacturing that source treated textiles, coatings, or packaging into these categories are directly in scope. For cosmetics specifically, Certivo's analysis of global cosmetics ingredient bans provides additional context on the direction of travel.

The Certificate of Compliance Obligation
The most immediate operational requirement is the Certificate of Compliance (CoC) process. NHDES may request a CoC from a manufacturer or supplier at any time, and the response window is 30 days.
A CoC must certify one of two positions:
The product does not contain intentionally added PFAS, or
The product qualifies for a specified exemption, stating the basis.
Key CoC rules:
✓ Even exempt products require a CoC that identifies the applicable exemption.
✓ Certificates must be signed by an authorized official of the manufacturer or supplier.
✓ Certificates may be posted online.
✓ Certificates must be updated if a product is reformulated or a new product is added.
The 30-day clock is where manufacturers without organized supplier data are exposed. If a CoC request arrives and the underlying declarations are scattered across emails and spreadsheets, meeting the window is difficult. This is the same evidence-retrieval problem that Certivo's Certificate of Conformance guide addresses: the certificate is only as reliable as the traceable supplier data behind it.

Exemptions Under RSA 149-M:64
Several exemptions narrow the practical scope. Manufacturers should confirm each against the certified rule text before relying on it.
Exemption | Summary |
|---|---|
Recycled content | Products made with at least 85% recycled content |
Pre-ban manufacture | Products manufactured before the ban takes effect |
Replacement parts | Replacement parts for products manufactured before the ban |
Federal preemption | Federally regulated items such as medical devices and pharmaceuticals |
The recycled-content and replacement-part exemptions require records that prove eligibility. A claimed exemption without supporting evidence is a weak position in an enforcement inquiry, which is why exemption tracking belongs inside the same materials and environmental compliance system that holds the underlying declarations.
Enforcement and Compliance Exposure
NHDES has administrative enforcement and penalty authority under the program and can require information to verify compliance. Enforcement exposure falls into three practical categories:
Regulatory inspection risk. NHDES may request a CoC at any time and can act on non-compliant or unsupported certifications.
Market-access risk. A covered product that cannot demonstrate non-PFAS status or a valid exemption cannot lawfully be sold or distributed into New Hampshire after January 1, 2027.
Customer and audit risk. Retailers and OEMs increasingly require upstream PFAS certifications before accepting products. A gap in your data surfaces first as a customer audit finding, not a state inspection.
Manufacturers that maintain audit-ready documentation across frameworks are better positioned to respond to any of these without a fire drill. Note that no software makes a company "audit-proof"; the goal is faster evidence retrieval, fewer surprises, and defensible records.
Supply Chain Impact: Why This Is a Multi-Tier Data Problem
The ban applies at the finished-product level, but the evidence lives with suppliers, often several tiers deep. A finished textile furnishing may contain a treated fabric from a Tier 2 supplier and a coating chemistry from a Tier 3 source. Certifying that product as non-PFAS requires declarations from each relevant tier.
The core challenges are consistent across state PFAS bans:
Mapping the ban's categories to specific SKUs and BOM components
Collecting PFAS declarations from suppliers who may report inconsistently
Validating supplier certificates rather than accepting them at face value
Maintaining historic, time-stamped records to support point-in-time queries
These are the same capabilities that Certivo's guidance on PFAS compliance across multi-tier supply chains and supplier data collection at scale describe. Structured supplier and contractor management turns a reactive scramble into a repeatable process.

A Practical Compliance Checklist Before January 1, 2027
Compliance, quality, and supply-chain teams can work this sequence now:
Scope your portfolio. Identify which SKUs fall into the nine covered categories.
Apply the correct PFAS definition. Screen against New Hampshire's TSCA structural definition, not a broad class assumption.
Map SKUs to BOMs. Link each covered product to its components and the suppliers responsible for them, using BOM-level compliance tracking.
Collect supplier declarations. Request PFAS data from relevant suppliers through a streamlined supplier documentation process rather than ad hoc email.
Validate, don't assume. Check supplier certificates for authenticity and completeness.
Document exemptions. Retain evidence for recycled-content, pre-ban, replacement-part, or federal-preemption claims.
Build the 30-day CoC response process. Assign ownership, define the retrieval path, and pre-stage certificate templates.
The Role of AI in Managing State PFAS Bans
State PFAS rules now arrive faster than most compliance teams can track manually, each with different definitions, categories, and deadlines. This is where AI-native compliance tooling changes the economics of the work.
Certivo's PFAS and chemical compliance platform is built for exactly this pattern. CORA-powered regulatory intelligence maps regulatory changes to affected products, and CORA-enabled analysis parses supplier documents to extract and validate PFAS declarations at scale, reducing the manual review that makes a 30-day CoC window stressful. The platform's features connect substance-level data to specific products so a compliance engineer can answer "which of our New Hampshire SKUs contain intentionally added PFAS" without a manual audit.
The objective is not to eliminate compliance risk. It is to shorten response time, improve evidence retrieval, and shift from reactive scrambling toward continuous, audit-ready readiness across every state PFAS framework, not just New Hampshire.
Executive Outlook
New Hampshire is one data point in an accelerating trend. New Jersey, Illinois, Minnesota, Maine, and others are enacting overlapping but non-identical PFAS product bans, each with its own definitions and timelines. Treating each as a separate manual project does not scale.
The strategic move for a global manufacturer is to build one substance-level, BOM-linked, supplier-backed data foundation that can answer any state's PFAS question on demand, then apply New Hampshire's specific definition and categories against it. Certivo's global PFAS compliance master guide frames how these frameworks fit together.
The New Hampshire PFAS product ban takes effect January 1, 2027, and CoC requests can arrive before then. The manufacturers who will meet the 30-day window comfortably are the ones staging supplier data and mapping their BOMs now.
