Wise Tall Utility Dry Box
Dry storage boxes typically use waterproof seals; brand discloses nothing about PFAS.
Wise does not disclose PFAS status for this dry box. Waterproof gaskets and seals in storage containers may contain PFAS, but material specifics are unavailable. Contact Wise directly for coating details.

The full breakdown
What it's made of and why it matters
The Wise Tall Utility Dry Box is a rigid plastic storage container, most likely polypropylene (PP) or acrylonitrile butadiene styrene (ABS), with a waterproof elastomer gasket seal. These base polymers are generally stable and food-contact approved in most jurisdictions when uncolored or minimally pigmented. The gasket material (typically EPDM rubber or silicone) is the secondary concern; if made from EPDM, it may shed trace compounds under UV or thermal stress, though this is minimal in sealed dry storage.
The brand's record and disclosure
Wise Company is known primarily for emergency preparedness and survival products. The brand provides no publicly available disclosure regarding PFAS content in gaskets or polymer formulations, which is standard silence in the utility storage category. No product recalls or safety controversies involving Wise dry boxes have been documented in public records. The company does not advertise third-party certifications (NSF, FDA, CPSIA) for this product line.
How it compares in its category
Dry storage boxes across brands (Rubbermaid, Otterbox, Pelican) are functionally similar and share the same material-class risks. Wise's pricing is competitive and the waterproof-seal design is standard for outdoor/utility use. Unlike food-storage containers, this category faces fewer regulatory scrutiny because dry goods typically do not extract leachables, and gasket materials are less exposed to temperature extremes than cookware. The lack of brand transparency on PFAS is not unusual for utility storage, though it represents a disclosure gap compared to leading outdoor brands.
If you buy it
Store only dry goods, tools, or non-food items to minimize any polymer leaching risk. Avoid leaving the box in direct sunlight for extended periods, as UV can degrade the gasket seal and accelerate release of trace additives. Inspect the gasket annually; replace if it becomes cracked, discolored, or loses elasticity. Do not use as a cooler for hot foods or fill with hot water, as this exceeds the polymer's safe thermal range (typically 60-80 degrees C for PP).
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.”
Gasket leachables and degradation
Elastomer seals (EPDM or silicone) in waterproof boxes may shed trace compounds or plasticizers under UV exposure or thermal cycling. Risk is minimal for dry storage but increases if the box is left in sunlight or used with hot items.
Polymer additives (BPA/BPS and pigment metals)
No reports of BPA or heavy metal leaching from Wise dry boxes. However, the brand does not disclose pigment sources or colorant composition, so potential heavy metals in colored plastics cannot be ruled out without testing.
Microplastic shedding
Rigid polypropylene or ABS in a utility box does not shed microplastics under normal dry storage conditions. Risk would only arise if the box is ground, crushed, or heated significantly.
PFAS in waterproof seal
Waterproof gaskets in consumer storage boxes may contain PFAS-based water-repellent coatings or Teflon-type coating (Teflon-family coating) components. Wise provides no disclosure. Risk is low in dry storage unless gasket is ingested or heavily abraded.
Thermal instability and fume release
Polypropylene is thermally stable below 100 degrees C. No reports of off-gassing or fume release from Wise dry boxes under normal storage conditions. Risk arises only if box is misused for hot storage or near heat sources.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
