Quick take: the rule of thumb
A label tells you what the seller chose to say. A test tells you what a lab found in a specific product. Look for the coating’s name, then for a test. Anything else is marketing language. This table covers claims seen on real pans in published tests, plus the legal terms behind them. We cite each pan result with its source and year, and we are not calling any brand good or bad.
Quick decoder
| If the label says… | What it tells you | Do | Don’t |
|---|---|---|---|
| “PFOA-free” | The coating was made without one PFAS, PFOA.2 | Ask what the coating is. Look for “PTFE” or a coating name in the spec. | Read it as “no PFAS.” In the Ecology Center’s test, most pans labeled PFOA-free were PTFE-coated.2 CR found PFOA in a PTFE pan labeled PFOA-free and no longer displays the claim in its ratings.1 |
| “PFAS-free” | The seller’s statement. CR’s product-safety experts call the term “misleading.” There are thousands of PFAS and most tests look for fewer than a hundred, and “free” may mean below a set level.1 | Ask: which PFAS were tested, by whom, on which product, when, and what is the detection limit? | Treat it as lab-verified unless a test report shows it. |
| “PTFE-free” | The coating is not PTFE. CR says this claim “can be more meaningful,” especially for ceramic-coated pans. The Ecology Center says a pan marked PTFE-free “likely doesn’t contain PFAS.”12 | Treat it as a useful starting point, and check that the coating type is named. | Treat it as proof that no PFAS is present. CR notes other PFAS are theoretically possible in even its non-detect pans.1 |
| “Non-toxic” | A claim regulators scrutinize. The FTC’s Green Guides say it is deceptive to misrepresent that a product is non-toxic, that the claim likely conveys non-toxic for humans and the environment, and that marketers need “competent and reliable scientific evidence” or must qualify it.4 | Ask what evidence supports it and what it covers. | Accept it as a test result. It is a general word with no defined test behind it. |
| “Ceramic” / “ceramic-coated” | Often a silicon dioxide–based coating. In the Ecology Center’s analysis, two pans labeled ceramic and PTFE-free had silicon dioxide coatings.2 | Look for a stated PTFE-free claim along with the word “ceramic.” | Assume every “ceramic” pan is PTFE-free without checking the spec. |
| Trade names: “stone,” “granite,” “diamond,” “titanium,” “German coating” | Marketing names. The Ecology Center found Granitestone, QuanTanium, DuPont Autograph and Greblon coatings to be PTFE. A pan sold as “Titanium Ceramic” (Goodful) had a silicon dioxide coating.2 | Look up the coating’s composition on the brand’s own materials page or ask the brand. | Guess the material from the name. The name can point either way. |
| A list of excluded chemicals (e.g., “free of GenX, PFBS, PFOS, PFOA”) | Those specific chemicals were said to be absent. The Ecology Center noted that a pan with exactly such a list used a PTFE coating, and that its testing was not designed to detect the listed chemicals.2 | Check whether the listing names the coating itself. | Read a long “free of” list as a full materials disclosure. |
| “FDA-approved” / “FDA-compliant” / “food-safe” | Food-contact rules apply to cookware. The FDA has authorized PFAS-containing nonstick coatings for pots and pans.3 | Read it as “allowed for food contact.” | Read it as “PFAS-free.” |
| “Eco-friendly,” “healthy cooking” | Vague. The Ecology Center found “eco-friendly” and “designed for healthy cooking” in the listing for a pan whose coating was PTFE.2 | Look for specifics (coating, tests, dates). | Treat these as safety claims. |
| “Tested” / “lab-verified” | Depends entirely on the test. | Ask for the report: lab, method, date, which chemicals, which product and batch. | Accept a badge, logo or unnamed “independent test.” |
| “Free of intentionally added PFAS” / “compliant in Minnesota” | The maker’s statement about how the product is made. Under Minnesota law, a certificate backed by test results is required only when the state directs the manufacturer to provide one.6 | Ask whether that statement is backed by a test and whether it is public. | Read it as a test result for this pan. |
California’s “free of” rule
See the evidence: California’s rule in detail
California’s AB 1200 limits “free of” claims by cookware makers. According to the Attorney General’s 2023 advisory, a manufacturer may not claim cookware is free of a specific chemical if that chemical belongs to a chemical group or class on a state “designated list” unless it was not intentionally added to the cookware.5 The advisory also describes website and label disclosure duties. They apply when a designated-list chemical is intentionally included in the handle or any food-contact surface.5 The rule is narrower than it sounds: the absence of a disclosure does not show that a product has no PFAS. We have not checked how it is being enforced.
Real examples from published tests
These are from published tests. They are not a ranking and say nothing about other products or years.
Claim: “PFOA-free”
Swiss Diamond (PTFE-coated). CR’s 2022 test found measurable PFOA (average 4 ppb) and other PFAS in the coating. The U.S. distributor disputed the results.1
Claim: “PTFE-free,” ceramic
Our Place Always Pan and Red Copper. CR (2022) did not detect any of 96 PFAS it looked for, and noted other PFAS are theoretically possible.1
Claim: long “free of” list
Ozeri Stone Earth. In the Ecology Center’s 2020 analysis the coating was PTFE. The Center said its test was not designed to check the listed chemicals.2
Claim: “granite coating … designed for healthy cooking”
MOKIKA listing on Amazon. The pan that arrived was branded Sunkitch Hotsun. Its packaging did not repeat the online claims except “eco-friendly,” and the coating was PTFE.2
The MOKIKA example shows the other risk: the product listing and the box can differ.
Five questions before you trust a claim
- What is the food-contact surface made of, in the brand’s own words?
- Which chemicals does the claim cover (one, a short list, or the whole class)?
- Is there a test? Who ran it, which method, on which product, and when?
- Does the test cover this exact model and a recent production run?
- What does the brand say it has not tested?
If the answers are missing, treat the claim as unverified. It may still be true. It just has no public evidence behind it yet.
What we don’t know
- Whether the pans in the examples are still sold in the same form, or whether their labels have changed. Those tests are from 2020 and 2022.
- How common any particular claim is today.
- Whether any specific brand’s current testing is better than what we could find.
