Smeg TSF99X Oven Baking Tray : 460x360mm X 20mm Deep
Lower PFAS concern, stainless steel baking tray with no nonstick coating or water-resistant treatment.
The Smeg TSF99X is a bare stainless steel baking tray with no nonstick or special coatings documented. Stainless steel cookware does not require PFAS-based Teflon-family coating or water-resistant treatments. No brand disclosure on PFAS exists, but the material itself presents lower concern than coated nonstick alternatives.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
The Smeg TSF99X is constructed from stainless steel with no nonstick coating, enamel, or ceramic glaze. This eliminates the primary chemical hazards associated with coated baking trays: no risk of Teflon-type coating (Teflon) fume release at high heat, no lead or cadmium in ceramic glazes, and no concern about polymer coating degradation over time. Stainless steel is chemically inert at normal baking temperatures and does not leach metals into food under typical use.
The brand's record and disclosure
Smeg is an Italian appliance brand with a strong reputation for build quality and design but has not made public statements about chemical safety testing or disclosure practices for baking accessories. The brand does not appear in major safety controversies related to cookware. No product-specific recalls or regulatory actions are on record for this tray model. Smeg's silence on safety certifications is typical for entry-level cookware brands; they do not routinely publish third-party test results for baking trays.
How it compares in its category
Uncoated stainless steel baking trays are among the safest options in the category, preferred by toxicology experts over nonstick variants. Most competing products (from brands like Wilko, Argon Tableware, or budget lines) offer similar bare steel construction. The main advantage over ceramic-coated trays is the absence of glaze leaching risk; the main trade-off versus nonstick is slightly slower food release and more frequent greasing needed. At this price point, material safety is comparable to mid-range alternatives.
If you buy it
Use the tray with standard baking practices: grease or parchment paper to prevent sticking. Stainless steel baking trays tolerate temperatures up to 300-350°C (typical oven range) without risk. Hand wash or place in dishwasher; the material is durable and unlikely to degrade. Replace only if the surface becomes significantly warped, rusted, or develops dents that prevent even baking. Expect a long service life with no coating wear or chemical leaching concerns.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Coating degradation and flaking
Uncoated stainless steel has no polymer or enamel layer to degrade. This hazard does not apply to this product.
Metal leaching (aluminum, iron, nickel)
Stainless steel can release trace amounts of iron and nickel under acidic conditions (e.g., tomato-based foods) or prolonged contact with salt. Exposure levels in normal baking are below regulatory concern, but those with nickel sensitivity should monitor for irritation.
Teflon-type coating and nonstick fume release
No nonstick coating present. This hazard does not apply.
Lead or cadmium in glaze or enamel
Bare stainless steel construction with no ceramic glaze, enamel, or decorative coating. This hazard does not apply.
Surface contamination and maintenance
Uncoated stainless steel can harbor bacteria or residue in crevices if not cleaned thoroughly. Standard dishwashing or hand-washing with hot water and soap prevents this; no special treatment needed.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
