HexClad cookware underwent a significant material change in 2024 that directly affects the answer to this question. Older HexClad pans used PTFE (the same polymer in Teflon) as their non-stick coating, while newer versions use a ceramic-based coating called TerraBond that contains no PTFE, PFOA, or other PFAS chemicals. Whether your HexClad is non-toxic depends almost entirely on when it was made and which line you own.
The 2024 Coating Switch
For most of its existence, HexClad used PTFE in the valleys of its distinctive hexagonal pattern. The raised stainless steel hexagons were always metal, but the recessed non-stick portions between them were a traditional fluoropolymer coating. That meant earlier HexClad pans carried the same concerns as any other PTFE-coated cookware, just with less total coating surface area because of the hybrid design.
Sometime in 2024, HexClad quietly transitioned to a ceramic-based coating. The company initially launched this formulation under the name TerraBond as a separate product line, then began rolling the ceramic coating into its standard cookware as well. If you purchased a HexClad set before 2024, particularly from retailers like Costco, your pans almost certainly contain PTFE. Sets manufactured later in 2024 and beyond use the newer ceramic formulation. HexClad’s customer service team can confirm which version you have if you send them your receipt.
What’s in the Newer Ceramic Coating
The TerraBond ceramic coating is a sol-gel formulation, meaning it starts as a liquid solution that hardens into a glass-like ceramic layer. Independent lab testing by Light Labs found zero detectable levels of PFAS, PFOA, PTFE, PFOS, and related fluorinated compounds in the TerraBond line. The results came back as “non-detect” across the board.
One detail worth noting: the ceramic coating reportedly contains HDPE (high-density polyethylene) mixed with the ceramic material during application. HDPE is the same type of plastic used in milk jugs and cutting boards. It’s broadly considered food-safe and doesn’t carry the same health concerns as fluoropolymers, but it does mean the coating isn’t pure ceramic in the way some buyers might assume.
What’s Under the Coating
Regardless of which version you own, the pan body itself is the same: a tri-ply construction with an aluminum core sandwiched between two layers of stainless steel. The aluminum serves as the heat conductor but never contacts your food directly because the stainless steel fully encapsulates it. Stainless steel is one of the most inert cooking surfaces available, so the base metal construction isn’t a toxicity concern.
The non-stick coating bonds to the stainless steel through a laser-etching process that creates a textured surface for the coating to grip. This mechanical bond reportedly achieves an adhesion strength of about 25 MPa, roughly 67% stronger than the industry standard. The practical result is that the coating is less likely to flake or peel compared to pans where non-stick is simply sprayed onto a smooth surface.
The PTFE Question for Older Pans
If you have a pre-2024 HexClad with PTFE, the safety picture is more nuanced. PTFE itself is chemically stable and considered safe at normal cooking temperatures. The concern with PTFE has always been heat: the coating begins to break down as temperatures approach 500°F, releasing fumes that can cause flu-like symptoms in people and are lethal to pet birds. HexClad’s U.S. site lists a maximum oven-safe temperature of 500°F, which sits right at that degradation threshold.
On the stovetop, an empty pan or one with very little oil can exceed 500°F within a few minutes on high heat. With food in the pan, temperatures stay well below that range during normal cooking. The older PTFE-coated HexClad pans also have less total non-stick surface than a fully coated pan because the stainless steel hexagons take up a significant portion of the cooking area. That reduces, but doesn’t eliminate, the amount of PTFE that could potentially off-gas.
The older pans were always free of PFOA, which is the manufacturing chemical once used to produce PTFE that has been linked to cancer and other health problems. PFOA was phased out of cookware production industry-wide by 2015. So even with PTFE present, the most harmful associated chemical was not part of the formula.
Scratches and Long-Term Wear
HexClad markets its pans as metal-utensil safe, but the company acknowledges that scratches can happen. Their position is that scratches are cosmetic and don’t affect safety. The hexagonal stainless steel pattern does provide a real structural advantage here: the raised metal peaks take most of the direct contact from spatulas and whisks, shielding the non-stick valleys below. This design genuinely reduces the rate at which the coating wears compared to a fully coated pan.
If the ceramic coating does wear through over time, the surface underneath is stainless steel, not a primer layer or bare aluminum. That means even a heavily worn HexClad pan doesn’t expose you to problematic materials. You’d lose non-stick performance long before you’d encounter a safety issue from the underlying construction.
How to Tell Which Version You Have
HexClad hasn’t made it especially easy for consumers to distinguish PTFE pans from ceramic ones at a glance, since the hexagonal pattern looks the same on both. Your best options are to check your purchase date (anything bought before mid-2024 is likely PTFE), look at the product packaging for TerraBond branding, or contact HexClad directly with your order details. If you bought an older PTFE set from Costco, their return policy is famously generous, and some buyers have reported successfully exchanging for the newer ceramic version.
