RTIC · Insulated Drink Tumblers
Rtic 40 oz Ceramic Lined Road Trip Tumbler
Ceramic lining suggests lower PFAS concern, but brand offers no transparency.
Ceramic-lined tumblers are typically free from PFAS coatings. RTIC does not publicly disclose PFAS testing or claims, leaving some uncertainty about materials and manufacturing.

The full breakdown
What it's made of and why it matters
The RTIC 40 oz features a ceramic interior lining bonded to stainless steel walls, a double-wall design that insulates without relying on plastic or synthetic polymer coatings. Ceramic is a fired mineral material (clay, silica, feldspar) that does not leach chemicals when in contact with food or beverages at normal use temperatures. Stainless steel (typically 18/8 grade) is chemically stable and does not degrade into drinking water under standard conditions. This material pairing avoids Teflon-type coating (Teflon-like) coatings and BPA-containing plastics found in many competing tumblers.
The brand's record and disclosure
RTIC is a private-label outdoor goods manufacturer (ownership has shifted; currently part of Koolaburra portfolio) with minimal public third-party testing or certification history. The company does not publish material safety data sheets or PFAS testing results for this product on its website or in response to public inquiries. No major recalls or safety controversies specific to the ceramic tumbler line are established in public records. The brand's silence on chemical composition and PFAS is typical of the drinkware category but represents a transparency gap.
How it compares in its category
Most insulated tumblers use synthetic polymer linings (often acrylic or epoxy coatings) or hard plastics that carry PFAS and leaching risks; ceramic lining is less common and positions this product as a safer alternative in that regard. Comparison products like Yeti Rambler use powder-coated stainless steel interiors (no ceramic), which also avoids plastic but offers less thermal insulation. Glass-lined tumblers offer similar safety but higher breakage risk and weight. The ceramic-lined approach is a genuine material advantage, though not unique to RTIC.
If you buy it
Ceramic coatings can chip or crack if dropped, exposing underlying metal; inspect before first use and discontinue use if damage appears. Hand wash recommended to avoid thermal shock that could degrade the ceramic bond; avoid dishwashers or extreme temperature cycling. Do not use with acidic beverages (citric acid, vinegar) for extended periods, as weak acid exposure can gradually etch ceramic glaze over months. Replace the tumbler if the ceramic lining shows visible cracks, flaking, or rust spots beneath.
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.”
Ceramic glaze lead/cadmium
No public testing or recalls document lead or cadmium in RTIC ceramic linings. Standard food-contact ceramics are regulated; however, RTIC does not disclose firing temperature or glaze composition, so independent verification is unavailable.
Coating delamination and metal exposure
Ceramic bonds to stainless steel via adhesive or mechanical anchoring; impact or thermal shock can cause chipping or peeling. If the underlying stainless steel is exposed to prolonged contact with acidic or chlorinated water, microscopic corrosion could eventually occur.
Stainless steel leaching (nickel)
Stainless steel (18/8 grade) does not significantly leach nickel or chromium into neutral pH water at room temperature. Risk would only emerge if the ceramic coating failed and the steel was exposed to acidic beverages over extended periods, which is unlikely in normal use.
Metallic contamination from manufacturing
No public recalls or complaints document metal shavings, paint chips, or particulates in RTIC tumblers. Standard quality control exists but is not independently audited.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
