What Ozark Trail Stainless Steel Swivel Tumbler is made of, ingredients and materials

This tumbler is constructed from stainless steel with a swivel lid, likely 18/8 or 18/10 food-grade stainless steel (chromium-nickel alloy). Bare stainless steel is chemically stable and does not leach under normal use conditions because the chromium oxide layer passivates the surface. Unlike coated drinkware (ceramic, enamel, non-stick), there is no glaze, paint, or polymer coating that can chip, degrade, or release contaminants into beverages.

⚠️

Bacterial growth in crevices

The swivel lid mechanism has joints and crevices where moisture can accumulate if not dried thoroughly. Regular hand washing and prompt drying minimize risk; mold or mildew can form if the tumbler is left wet for extended periods, but this is a hygiene issue rather than a material hazard.

70/ 100

What’s reassuring

✅

Bare uncoated material

Recorded as a bare, uncoated material with no surface coating or treatment.

100/ 100
✅

Metal leaching (chromium, nickel)

Food-grade stainless steel is passive and does not leach chromium or nickel under normal room-temperature or warm beverage conditions. No leaching has been documented for bare stainless steel drinkware in peer-reviewed studies or consumer reports.

95/ 100
✅

Coating degradation and flaking

No glaze, enamel, or polymer coating is present on the tumbler body itself, eliminating the primary failure mode for coated drinkware. The swivel lid may have a small rubber or plastic gasket; inspect for cracks but replacement is straightforward.

95/ 100
✅

Microplastic shedding

The tumbler body is stainless steel (not plastic), so it does not shed microplastics. The lid likely contains a minimal plastic or rubber seal; no evidence of degradation from normal cold or hot beverage use.

95/ 100
✅

Sharp edges or metal burrs on seams

Budget stainless steel manufacturing may have unpolished seams or edges, but no recalls or complaints are on record for this model. Inspect the rim and seams by hand before first use; file any rough spots if present.

95/ 100

The full breakdown

The brand's record and disclosure

Ozark Trail is a private-label budget brand owned by Walmart with minimal published safety certifications or material transparency statements. No major recalls or safety controversies are on record for this specific tumbler model. The brand does not publicly disclose PFAS testing or coating composition, which is typical for low-cost drinkware manufacturers but limits independent verification of material safety.

How it compares in its category

Bare stainless steel tumblers present lower concern for coating degradation as a hazard vector since they lack a coating that could degrade. Compared to ceramic tumblers (glaze lead risk), enamel cups (chipping), plastic bottles (BPA/BPS leaching), or silicone wraps (off-gassing), uncoated stainless steel avoids these failure modes. The Ozark Trail version is functionally equivalent to premium stainless steel tumblers at lower price, with no documented material disadvantage.

If you buy it

Rinse before first use. Stainless steel resists corrosion in acidic beverages (coffee, juice, citrus) and hot water without degradation. The swivel lid mechanism should be inspected periodically for cracks or loose hinges that could allow metal shavings; replace the lid if damaged. Hand washing is recommended to avoid dishwasher abrasion of the swivel joint over time; dry promptly to prevent water spotting.
