USA Pan Half Sheet Pan
Nonstick type unlisted; no PFAS transparency from brand.
USA Pan makes this carbon steel sheet with nonstick coating, but won't say what the coating is or confirm PFAS status. That leaves buyers guessing.

What’s concerning
Non-stick, chemistry undisclosed
Advertised as non-stick but coating type is not explained.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
cookware is a category where PFAS exposure is more common.
Teflon-type coating nonstick fume risk (conditional)
If the coating is Teflon-type coating-based and heated above 500°F, degradation can release polymer fumes linked to flu-like symptoms in humans and acute injury in pet birds. Brand does not confirm coating type, so risk cannot be ruled out; heating discipline is essential pending clarification.
Coating degradation and metal leaching
Carbon steel cookware nonstick coatings degrade over time with use and washing, particularly in dishwashers. Microscopic wear exposes underlying steel; while carbon steel itself is not toxic at culinary levels, flaking coating particles are undesirable. Imusa does not specify recoating options or expected lifespan.
PFAS
The absence of any public PFAS commitment or coating specification sheet from Imusa, combined with industry-wide use of Teflon-type coating in affordable nonstick cookware, suggests likelihood that PFAS-containing coatings may be present. This is a transparency and informed-consent issue rather than an acute toxicity guarantee.
Source: ATSDR ↗What’s reassuring
Lead
No recalls or public test results document heavy metal contamination in USA Pan carbon steel sheet pans. Imusa is a US-based company with decades of market presence; this hazard is not on record, but third-party lab testing is not published.
Source: ATSDR ↗Aluminum leaching (if aluminum core present)
USA Pan sheet pans are specified as carbon steel, not aluminum composite, so aluminum leaching is not a material concern for this product. Risk applies only if construction differs from manufacturer claims.
The full breakdown
What it's made of and why it matters
USA Pan half sheet pans are carbon steel with an applied nonstick coating whose specific chemistry Imusa does not disclose publicly. Carbon steel itself is inert and durable, but the nonstick layer is the critical unknown: if it is Teflon-type coating-based (Teflon), it poses fume risks above 500°F; if it is ceramic or silicone-based, the risk profile differs. Without brand transparency on coating type, consumers cannot make fully informed decisions about heat exposure or replacement timing.
The brand's record and disclosure
Imusa is a long-established cookware manufacturer with no public PFAS statements, certifications (such as GOTS or Cradle to Cradle), or third-party safety disclosures on their nonstick formulations. The brand does not list coating composition on packaging or websites reviewed in public sources. This silence is common among mid-market cookware makers but leaves consumers dependent on reverse-engineering or assumption about whether Teflon-type coating, ceramic, or proprietary alternatives are used.
How it compares in its category
Carbon steel sheet pans with nonstick coatings occupy a middle ground: more durable than traditional aluminum with nonstick, but less transparent than premium brands (Caraway, Our Place) that explicitly label coatings as PFOA-free ceramics. Bare carbon steel alternatives require seasoning but avoid coating degradation entirely. Stainless steel pans avoid coating risk but demand more oil and skill. USA Pan's price point and durability are competitive, but lack of disclosure puts it behind more forthcoming competitors.
If you buy it
Use only at moderate heat (under 400°F for roasting; avoid broiler use above 500°F until coating type is confirmed via Imusa support). Hand wash only; dishwasher use accelerates coating wear and increases leaching risk. Inspect the coating annually for chips, peeling, or discoloration; replace if damage appears. Contact Imusa directly to request coating material specifications before purchase or use if PFAS exposure is a primary concern.
