SUPCASE UB Pro Series Case for Galaxy S26 Ultra
Lower concern rigid case, but no PFAS disclosure from brand.
Phone cases made from rigid TPU and polycarbonate are unlikely to contain intentional PFAS. Brand provides no public statement on PFAS or material sourcing.

The full breakdown
What it's made of and why it matters
The UB Pro Series combines a rigid polycarbonate outer shell with a softer thermoplastic polyurethane (TPU) inner lining. Polycarbonate is durable and impact-resistant but historically associated with BPA leaching under stress or heat; TPU is flexible, latex-free, and resistant to cracking but can degrade under prolonged UV exposure. Neither material is designed for food contact, and phone cases are not intended to touch skin for extended periods, so direct absorption risks are low. The case's primary function is impact protection, not chemical barrier.
The brand's record and disclosure
SUPCASE is a large third-party phone accessory manufacturer with no publicly documented safety certifications (RoHS, REACH, etc.) or material disclosure statements specific to this model. The brand has not published a formal PFAS reduction commitment or transparency report, and no major recalls or safety incidents are on record for this product line. This silence is typical for accessory brands in this price segment; it does not indicate a problem but reflects a lack of third-party verification.
How it compares in its category
Phone cases in this category (rugged hybrid TPU/PC designs) are among the lowest-risk consumer products because they do not contact food, skin extensively, or get heated above 60-70°C in normal use. SUPCASE is a market-standard provider; comparable cases from OtterBox, Spigen, and others use identical material chemistries and carry similar disclosure gaps. The rigidity of polycarbonate and TPU stability under indoor ambient conditions make chemical leaching into the device itself minimal.
If you buy it
Keep the case away from direct prolonged sunlight (UV can degrade TPU over 1-2 years) and avoid exposing it to solvents or high heat (>80°C). Clean with mild soap and water only; do not use bleach or abrasive cleaners on the TPU lining. Replace the case if the TPU yellows significantly, cracks, or the polycarbonate develops stress fractures, as degraded material may release microplastics or dust. Store in a cool, dry place when not in use.
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.”
BPA/BPS in polycarbonate
Polycarbonate may contain residual BPA or BPS; however, migration risk is negligible because the case does not contact food, beverages, or skin continuously. No heating of the product occurs in normal phone use, which is the primary trigger for leaching.
TPU degradation and microplastics
TPU degrades over extended UV exposure or mechanical stress, potentially releasing microparticles or off-gases. This is more aesthetic (yellowing, brittleness) than acute toxicological, but replacement within 2-3 years is advisable to avoid dust accumulation.
Chemical additives (colorants, stabilizers, flame retardants)
SUPCASE does not disclose specific additives or colorant sources for this model. Polycarbonate and TPU formulations may contain heavy metal stabilizers (cadmium, lead) or flame retardants, but no recalls or test reports for this product indicate problems. Standard manufacturing practices in this category do not typically use restricted substances.
Off-gassing (VOCs) during manufacturing
New cases may emit odor from residual solvents or plasticizers during the first few days; this dissipates rapidly in open air. No volatile organic compounds (VOCs) are documented as problematic for this product line, and the risk is minimal because phone cases are not enclosed in a room for extended periods.
Allergic contact dermatitis from TPU or additives
TPU is hypoallergenic and latex-free; no widespread allergen reports exist for SUPCASE cases. Risk is low because contact is indirect (case touches phone, not skin directly for hours at a time).
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.
