2 Pack Waterproof Compatible With Samsung Galaxy Smarttag2 Holder, Tpu
Skip until Samsung discloses waterproof treatment composition.
TPU case marketed as waterproof, but Samsung provides no disclosure on waterproofing agents or PFAS status. Unspecified coatings on polymers commonly use PFAS-based water repellents.

The full breakdown
What it's made of and why it matters
This product is a TPU (thermoplastic polyurethane) protective case with an undisclosed waterproof treatment applied to the material. TPU itself is a flexible, non-toxic plastic commonly used in phone cases and device holders because it resists tearing and absorbs impact. The waterproof coating's chemical identity is the critical unknown: waterproofing can be achieved with PFAS-based water repellents or safer alternatives, but Samsung has not published the treatment formula.
The brand's record and disclosure
Samsung maintains no public commitment to PFAS phase-out in consumer accessories and does not disclose waterproof treatment chemistry for this product line. The company has faced scrutiny over PFAS use in semiconductor manufacturing but has not extended transparency to small accessories like smart tag holders. No environmental or safety certifications (e.g., Oeko-Tex, bluesign) are claimed for this product, which is typical of budget accessory lines.
How it compares in its category
Most third-party smart tag holders use unlabeled TPU with similar waterproof coatings, so this product sits in a category-wide transparency gap rather than standing out as worse. Some premium alternatives specify PFAS-free silicone or use mechanical waterproofing (seams, gaskets) instead of chemical coatings. This Samsung-branded version offers no disclosed safety advantage over generic competitors, though brand familiarity may drive choice.
If you buy it
Avoid prolonged exposure to direct sunlight or heat above 60 degrees Celsius, as TPU can degrade and leach plasticizers if thermally stressed. Do not submerge the holder in salt water; rinse with fresh water after any saltwater exposure and dry thoroughly to prevent mold growth inside. Replace the holder if the TPU becomes sticky, discolored, or develops a chemical odor, as these signs indicate material breakdown. Store in a cool, dry place away from oils and solvents that can soften TPU.
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.”
Plasticizer leaching from TPU degradation
TPU contains plasticizers (typically adipates or phthalate alternatives) that can migrate into skin or the device if the material is exposed to heat, UV, or mechanical stress over years of use. This is not an acute risk for short-term use but cumulates with age and mishandling.
Waterproof coating composition (non-PFAS)
The waterproof treatment is chemically unidentified and could contain non-PFAS alternatives (siloxanes, acrylics) with their own stability and off-gassing profiles. Without disclosure, residual solvent or volatile organics cannot be ruled out, especially during manufacturing off-gassing in the first weeks of use.
Microbial growth and biofilm in wet conditions
If the holder traps moisture around the Samsung Galaxy SmartTag2 after waterproof immersion, bacterial or fungal biofilms can develop inside crevices, potentially causing device corrosion or odor over months of storage.
Allergic contact dermatitis from additives
No specific reactions to this product have been reported, but TPU formulations sometimes contain accelerators or antioxidants that can trigger skin sensitization in susceptible individuals with prolonged skin contact.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
