If you run a restaurant, cafe, or catering business, “PFAS-free” has probably shown up on a supplier invoice, a state compliance notice, or a customer’s Instagram comment in the last year or two. It’s not a marketing buzzword you can safely ignore — a growing list of states have made intentionally added PFAS in food packaging illegal to sell, and the FDA has confirmed the primary source of these chemicals in U.S. food packaging has already left the market.
But “PFAS-free” on its own is just a claim. What actually backs it up — and what you should say when a customer asks you to prove it — is where most operators get stuck. This guide covers what PFAS-free certification actually means, the specific programs that verify it (NSF P525, BPI, CMA), which states regulate it, safe alternative materials, and exactly how to explain all of this to a customer standing at your counter without overpromising.
Quick Answer
There is no single universal “PFAS-free” government seal. Proof comes in tiers: a supplier’s written Certificate of Compliance or Safety Data Sheet (a self-declaration), a third-party compostable certification from BPI or CMA that screens for PFAS at a 100 ppm total fluorine threshold, or NSF P525 — a dedicated packaging safety certification launched in September 2025 that lab-tests finished packaging for PFAS, BPA, phthalates, and heavy metals. To explain this to a customer, keep it simple: “independently tested, not just labeled.”
What PFAS Is and Why It Was in Your Packaging
PFAS is a large family of synthetic chemicals prized for repelling grease, oil, and water — which is exactly why they were used for decades in molded fiber bowls, sandwich wrappers, pizza boxes, popcorn bags, and bakery bags. PFAS compounds break down extremely slowly in the environment and the body, earning the “forever chemicals” nickname, and research has linked long-term exposure to a range of health concerns.
In February 2024, the FDA announced that PFAS-based grease-proofing substances were no longer being sold into the U.S. market for use on paper and paperboard food packaging, following a voluntary phase-out manufacturers committed to in 2020. That closes the primary federal supply-side source, but it doesn’t mean every product on every supplier’s shelf has already been reformulated — legacy stock and imported packaging can still contain PFAS, which is exactly why certification and testing matter more than a label alone.
PFAS-Free Packaging Certification: What It Actually Means
When a supplier says their packaging is “PFAS-free,” ask which of three tiers of proof they’re offering — they are not interchangeable. The weakest is a manufacturer declaration: a Certificate of Compliance or Safety Data Sheet stating no PFAS was intentionally added during manufacturing. It’s a reasonable starting point but isn’t independently verified.
The next tier is third-party compostable certification. Since January 2020, BPI (Biodegradable Products Institute) and CMA (Compost Manufacturing Alliance) have required PFAS screening as a condition of certification, testing total fluorine content via combustion ion chromatography at ISO 17025-accredited labs against a 100 ppm pass/fail threshold. If your packaging carries a current BPI or CMA mark, it has already cleared this screening — but check the certification date, since compostable certifications issued before 2020 may predate the PFAS requirement.
The most rigorous tier is NSF P525, a packaging-specific safety certification NSF launched in September 2025. It applies to single-use primary and secondary food-contact packaging — takeout containers, coffee cups, wrappers, trays, and bottles — and uses food-simulant lab testing plus technical review to confirm the material is free of PFAS along with BPA, phthalates, heavy metals (lead, arsenic, cadmium, mercury), and mineral oil aromatic hydrocarbons. It’s worth distinguishing this from NSF 537, a separate NSF program launched in March 2025 for food equipment materials and nonfood compounds like food-safe lubricants and sanitizers (total organic fluorine under 50 ppm, retested annually) — NSF 537 does not cover paper or molded fiber packaging, so don’t accept it as proof for your takeout boxes.
When you request documentation from a supplier, ask for the specific certificate or listing number, not just a marketing claim, and check it against the issuing body’s public registry — BPI maintains a searchable certified-products database, and NSF-certified products are listed in the NSF White Book.
How to Explain PFAS-Free Certification to Foodservice Customers
Most customers don’t want a chemistry lesson on parts-per-million thresholds — they want a short, honest answer that signals you’ve actually checked, not just repeated a supplier’s marketing line. A simple three-part script works for staff: what it means (“no forever chemicals were intentionally added to this packaging, and it’s been lab-tested to confirm that”), how you know (name the actual documentation you hold — a BPI certification number, an NSF P525 listing, or your supplier’s Certificate of Compliance), and where to verify it if asked (offer to show the certificate or registry listing).
Avoid overclaiming. Don’t say “100% PFAS-free” or “chemical-free” — certifications test against a ppm threshold, not absolute zero, so the accurate phrasing is “no intentionally added PFAS, verified through [the specific certification you hold].” That specificity also builds more trust than a vague eco-claim, since a curious customer who searches “PFAS-free packaging certification” themselves will find the same distinctions covered here.
Put this language where staff and customers actually encounter it: a one-line menu or signage callout (“Our to-go containers are PFAS-free, certified by [BPI/CMA/NSF P525] — ask us for details”), a short FAQ on your website, and a printed or QR-linked copy of the supplier’s certificate kept at the register or in a training binder so staff never have to guess when a customer pushes for specifics.
State Bans You Need to Know About
Roughly a dozen states — including California, Colorado, Connecticut, Hawaii, Maine, Maryland, Minnesota, New York, Oregon, Rhode Island, Vermont, and Washington — have enacted laws restricting intentionally added PFAS in food packaging or foodservice ware. Several are already in effect (New York, California, and Washington were among the earliest, with others phasing in through 2024 and 2025), and Maine has additional plant-fiber packaging requirements taking effect in 2026. Scope varies: some bans cover all food packaging and foodware, while others apply specifically to paper-based or molded-fiber packaging.
If you operate in multiple states, or your distributor ships nationally, the safest move is to require PFAS-free packaging across the board rather than tracking which SKU is legal in which state. To check your exposure: pull your current packaging invoices, identify the manufacturer and product line for each grease-resistant item, and ask your supplier directly for a written PFAS-free certification or Certificate of Compliance — and specify which tier of proof (declaration, BPI/CMA, or NSF P525) you need.
PFAS-Free Alternatives and Testing Before You Switch
Common PFAS-free alternatives include molded fiber made from bagasse (a sugarcane byproduct) or wheat straw, which are naturally more oil-resistant and can be finished with water-based or bio-based barrier coatings instead of fluorinated ones. Some manufacturers use thermoforming on molded fiber to boost grease resistance without any added coating, while others use plant-based or shellac-based barrier coatings on molded pulp.
Don’t assume “recyclable,” “compostable,” or “kraft paper” automatically means PFAS-free — none of those labels guarantee it on their own, which is exactly why the certification distinctions above matter. When testing a new PFAS-free line, pilot it with your highest-grease menu items first (a wrapper that holds up for a dry sandwich may fail with a greasy burger or saucy wings) and budget for a transition period, since PFAS-free alternatives can cost more per unit and lead times may be longer as demand shifts industry-wide.
PFAS-free packaging certification FAQs
What certifications prove that food packaging is PFAS-free?
Three tiers: a supplier’s written Certificate of Compliance or Safety Data Sheet (a self-declaration), BPI or CMA compostable certification (which has screened for PFAS at a 100 ppm total fluorine threshold since 2020), and NSF P525, a packaging-specific certification launched in September 2025 that lab-tests for PFAS, BPA, phthalates, and heavy metals in finished packaging.
Is NSF 537 the same as PFAS-free packaging certification?
No. NSF 537 certifies food equipment materials and nonfood compounds like lubricants and sanitizers, not paper or molded fiber food packaging. For takeout boxes, wrappers, and bowls, look for NSF P525 or a current BPI/CMA certification instead.
How do I explain PFAS-free certification to a customer without overpromising?
Say what it means (no intentionally added PFAS, lab-tested to confirm it), name the specific certification or documentation you hold, and offer to show it if asked. Avoid absolute claims like ‘100% PFAS-free,’ since certifications test against a ppm threshold rather than zero.
Is all food packaging required to be PFAS-free now?
Not universally. Roughly a dozen states restrict intentionally added PFAS in food packaging, with more considering similar legislation, and the FDA has confirmed PFAS grease-proofing substances are no longer sold into the U.S. market for that use. There’s no single nationwide ban yet, so requirements depend on which states you operate in.
How can I tell if my current packaging contains PFAS?
Ask your supplier or manufacturer for a written PFAS-free certification or Certificate of Compliance for each product line, and specify whether you need a self-declaration, a BPI/CMA certificate, or NSF P525 documentation depending on how much verification you need.
What materials replace PFAS coatings in food packaging?
Common alternatives include molded fiber from bagasse or wheat straw, water-based and bio-based barrier coatings, and thermoformed molded pulp that boosts grease resistance without any added coating.
