On August 12, 2026, the EU stops caring whether your packaging is PFAS-free. It starts caring whether you can prove it. That is a different problem, and most food brands importing grease-resistant wraps, molded fiber bowls, and coated paperboard are not ready for it. A supplier emailing you a one-line “yes, our products are PFAS-free” used to be enough to tick a box. Under the Packaging and Packaging Waste Regulation, that email is now worth nothing.
The regulation does not just set limits—it sets an evidentiary standard. If a customs officer or a buyer’s auditor asks how you know a container is compliant, the answer has to be a lab report, not a promise. For anyone sourcing food-contact packaging from China or anywhere else, the shift from “trust” to “documented proof” is the part of the PFAS ban that actually changes how you buy. Here is what the numbers are, how the testing works, and exactly what you should be demanding from suppliers before the deadline.
The Three Numbers That Decide Compliance
The PPWR restricts intentionally added PFAS in food-contact packaging using three thresholds, and they all matter because a sample only passes if it clears all of them. The first is 25 ppb (parts per billion) for any single PFAS compound measured through targeted analysis. The second is 250 ppb for the sum of PFAS measured through targeted analysis. The third—and the one that triggers most of the testing drama—is 50 ppm (parts per million) for total fluorine, which includes polymeric PFAS and is the screening gate everything passes through first.
Two details trip people up. These are extraordinarily low limits: 25 ppb is 25 parts in a billion, a level you cannot eyeball, smell, or infer from a spec sheet. And there is no grandfathering—packaging manufactured before August 2026 cannot be placed on the EU market after the deadline if it exceeds the limits, so old inventory does not get a pass. The regulation entered into force as Regulation (EU) 2025/40, replacing the old Packaging Directive with direct, identical obligations across all 27 member states. If you need the wider regulatory picture beyond PFAS, our EU PPWR compliance guide for the August 12, 2026 deadline covers the recyclability and labeling clauses that land on the same date.
How the Testing Actually Works
You do not test for “PFAS” in one shot—it is a two-tier process, and understanding it tells you what to ask for. Tier one is total fluorine (TF) screening. Because every PFAS molecule contains fluorine atoms, a lab first measures total fluorine in the material. If the result is below 50 ppm, the sample is considered compliant and no further testing is needed. This is the cheap, fast gate, and for genuinely non-fluorinated packaging it is often where the story ends.
Tier two kicks in only when total fluorine exceeds 50 ppm. At that point the burden flips: the supplier has to prove the fluorine is not from restricted PFAS. That means targeted PFAS analysis—typically methods like LC-MS/MS for individual compounds and pyrolysis-GC/MS to confirm whether the fluorine is organic or inorganic—measured against the 25 ppb and 250 ppb limits. This tier is more expensive and slower, which is exactly why suppliers who reformulated early to non-fluorinated barriers have an advantage: their products clear tier one and never trigger the costly second round. When you collect quotes, ask which tier a product’s documentation reflects; it tells you how clean the formulation really is.
Why a Supplier’s Word Is No Longer Enough
This is the line most buyers have not internalized: self-declarations do not satisfy the PPWR. A supplier statement, a brochure claim, or a sales rep’s verbal assurance is not evidence under the regulation. What counts is a Certificate of Analysis (CoA) from an accredited laboratory—a document tied to a specific material, a specific test method, with stated limits of quantification at the decision thresholds, blank controls, and a measurement-uncertainty statement. The PPWR embeds what compliance specialists call a documented-proof principle: you hold the test report, or you do not have a defensible position.
That matters for liability, not just paperwork. As the importer or brand placing the product on the EU market, you can be the legally responsible party—so if a supplier’s “PFAS-free” claim turns out to be unsupported, the exposure can land on you, not them. This is the same documentation discipline we flagged in what every food packaging buyer needs from their supplier now: the goal is to move every compliance claim from a conversation into a file you can produce on demand. Treat the CoA the way you treat a commercial invoice—no document, no shipment.
What to Demand From Your Supplier Before August
Turn the principle into a procurement checklist you actually run before placing orders. First, request a recent CoA from an ISO 17025-accredited lab for each food-contact item—not a generic factory certificate, but a report naming the specific product. Second, confirm the report covers the right scope: total fluorine screening at minimum, and targeted PFAS analysis if total fluorine came back above 50 ppm. Third, check the dates—a CoA from two years ago on a formulation that may have changed is weak; ask when the tested batch was produced and whether the formulation is still current.
Fourth, ask what the barrier is made of. If a supplier achieved grease resistance without fluorochemistry—using, for example, dispersion coatings, PVOH, or other non-fluorinated systems—they should say so plainly and the TF screen should confirm it. Fifth, build the CoA requirement into your purchase terms so it is contractual, not a favor. US buyers should run the same drill against state rules, which differ from the EU’s and are tightening on their own schedule; our 2026 state-by-state PFAS guide for importers maps where the US lines are drawn. The buyers who get caught flat-footed in August will be the ones who assumed “PFAS-free” on a website meant the same thing as a lab report. It does not.
The Takeaway
The PFAS ban is real, but the operational shift it forces on buyers is subtler than “stop using PFAS.” It is that compliance is now an evidence problem: the EU will accept a defensible Certificate of Analysis from an accredited lab and reject everything softer than that, including the supplier assurances most procurement teams have relied on for years. Get ahead of August 12 by treating PFAS documentation as a required shipping document—total fluorine screening as the gate, targeted analysis where the gate fails, and a current, product-specific CoA in your file for every food-contact item you import. The packaging that survives the deadline is not just PFAS-free. It is provably PFAS-free.
At gqthpack.com we supply food packaging with non-fluorinated barriers and provide the accredited lab documentation buyers need to clear PPWR and US state requirements. Talk to our team about getting the test reports for your next order on file well before the August deadline.
