PFAS-Free Declarations: How to Prove Chemical Compliance to Retail Buyers¶

If you supply consumer goods, apparel, cosmetics, or electronics to major retailers or online marketplaces, you have likely received a sudden, urgent request for a PFAS-Free Declaration.

Per- and polyfluoroalkyl substances (PFAS)—commonly dubbed "forever chemicals" due to their extreme persistence in the human body and environment—are facing an unprecedented wave of global regulation. In the United States, several states (including California, Maine, and Vermont) have enacted strict bans on intentionally added PFAS in consumer products.

Meanwhile, the European Union is evaluating a blanket restriction under REACH.

To protect themselves from immense liability and potential class-action lawsuits, retail giants (such as Amazon, Target, and Costco) are enforcing strict "flow-down" policies. If you cannot provide a valid, verifiable chemical compliance statement proving your products contain no intentionally added PFAS, your inventory will be immediately rejected and your vendor status terminated.

Here is how to audit your supply chain and draft a legally compliant PFAS-free declaration.

1. What Are PFAS and Where Are They Found?¶

PFAS are a class of thousands of synthetic organic chemicals characterized by strong carbon-fluorine bonds. These bonds make them exceptionally resistant to heat, water, oil, and staining.

Because of these properties, PFAS are ubiquitous in consumer manufacturing: * Textiles & Apparel: Used in durable water repellent (DWR) coatings, outdoor gear, and stain-resistant upholstery. * Food Contact Materials: Used in oil-resistant paper, fast-food wrappers, and non-stick cookware. * Electronics: Used in cable insulation, semiconductors, and circuit boards to prevent overheating. * Cosmetics: Used to improve the spreadability and water-resistance of makeup and lotions.

2. The Legal Reality of a "Self-Declaration"¶

Many brands believe that to declare a product "PFAS-Free," they must send every item to an expensive laboratory for fluorine testing.

While lab reports (such as total fluorine screening) provide the highest level of assurance, the vast majority of retail compliance is based on self-declarations backed by supply chain due diligence.

A PFAS-free declaration is a legally binding document. By signing it, you are certifying to your buyer that, to the best of your knowledge and based on written assurances from your raw material providers, no PFAS chemicals were intentionally added at any stage of production.

3. How to Audit Your Supply Chain (The Step-by-Step Process)¶

To build an audit-ready chemical compliance file, you must execute a systematic supply chain inquiry.

Step 1: Map Your Bill of Materials (BOM)¶

Identify every raw material, coating, and component in your product. Isolate the "high-risk" materials, such as water-resistant fabrics, non-stick coatings, and flexible plastics.

Step 2: Deploy Supplier Attestation Forms¶

Send a formal, structured PFAS attestation request to your upstream suppliers. Do not accept a simple "Yes/No" email. The supplier must formally sign an attestation confirming that: * No PFAS substances (including PFOA, PFOS, or GenX) were intentionally added during raw material selection or manufacturing. * They have verified compliance with their own sub-tier chemical providers.

Step 3: Compile the Evidence File¶

Keep all signed supplier attestations, material safety data sheets (MSDS), and lab reports (if available) organized in a single, central folder. This is your legal shield if your product's chemical safety is ever challenged.

4. Draft Your PFAS-Free Declaration (Mandatory Fields)¶

A legally robust PFAS-free declaration must include: 1. Product Identification: Precise brand name, product description, and SKU/model numbers. 2. Regulatory Citation: Explicit references to the specific state or federal regulations you are complying with (e.g., California Assembly Bill 1817 for textiles, or TSCA Section 8(a)(7) in the US). 3. Scope of the Claim: State clearly that "no PFAS chemicals were intentionally added during raw material selection, manufacturing, or packaging". 4. Basis of the Claim: Explicitly state that the declaration is based on thorough supply chain audit and written supplier confirmations. 5. Signature & Date: Signed and dated by an authorized officer of your company (such as the Head of Quality or CEO).

5. Automating Chemical Compliance with Sustalium¶

Chasing dozens of global suppliers for signed chemical attestations via email is a massive operational headache.

Sustalium’s REACH & RoHS compliance platform simplifies your chemical due diligence.

Instead of manual email chains, our platform automates supplier requests. We provide suppliers with a structured portal to upload their PFAS attestations and chemical disclosures. Sustalium securely stores this evidence at the component level and automatically generates a public-facing, verified PFAS-free declaration page. You can share this instantly via a live link or packaging QR code, giving retail buyers immediate proof of compliance.

Frequently Asked Questions¶

Is 'PFAS-Free' the same as 'Fluorine-Free'? Not necessarily, but they are closely linked. Laboratories typically test for "Total Fluorine" to screen for PFAS, as all PFAS contain fluorine bonds. If a lab report shows zero total fluorine, it is practically guaranteed to be PFAS-free. However, some organic fluorine compounds are not classified as harmful PFAS.

What is the 'intentionally added' standard? Most current US and EU state regulations focus specifically on "intentionally added" PFAS—meaning chemicals added during manufacturing to serve a specific function (like waterproofing). Trace, unintentional contamination from machinery or manufacturing lubricants is generally exempted under strict limit thresholds.
