Wise 5601-13 Boaters Dry Box Small
Lower concern but verify waterproof sealant composition with brand.
Wise boaters dry boxes are rotomolded polyethylene, typically lower-risk base material. Brand does not disclose PFAS status or sealant chemistry, leaving waterproofing treatment exposure unclear.

The full breakdown
What it's made of and why it matters
The Wise 5601-13 is constructed from rotomolded polyethylene (PE), a dense plastic formed by heat-molding powdered resin in a rotating mold. This manufacturing method produces a seamless, durable shell with no weak seams or joints, making it inherently more resistant to leaks than injection-molded alternatives. Rotomolded PE is food-contact safe under normal conditions and does not leach BPA or phthalates because neither chemical is used in its formulation. The waterproof sealing system (likely a gasket or rubber seal) is the primary chemical concern and should be confirmed PFAS-free with the manufacturer.
The brand's record and disclosure
Wise is a boat-accessory manufacturer with no public sustainability certifications or detailed chemical disclosure statements on file. The brand has not communicated a formal PFAS policy or third-party testing results for this product line. No recalls or safety violations related to the 5601-13 have been documented in public databases. Contacting Wise directly regarding the composition of waterproof gaskets and sealants is necessary before purchase if PFAS avoidance is a priority.
How it compares in its category
Rotomolded dry boxes are among the safest food-storage and gear-storage containers available because the production method avoids the chemical additives common in injection-molded plastics. Competitors using cheaper injection-molding may include plasticizers or UV stabilizers; Wise's rotomolded approach eliminates most of these. The main differentiator is the waterproof seal composition, which varies by manufacturer. For marine use, this product is competitive in safety profile with Pelican and Otterbox alternatives.
If you buy it
Rotomolded polyethylene is extremely durable and does not degrade or leach from normal use, heat exposure up to roughly 120F (48C), or prolonged sunlight. Do not store it in direct sunlight for years on end, as UV exposure will eventually make the plastic brittle, though this takes many seasons. Inspect the waterproof gasket annually and replace it if it hardens or cracks. Rinse with fresh water after saltwater exposure to prevent corrosion of metal hardware.
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.”
Polyethylene degradation (microplastics)
Rotomolded PE does not shed microplastics under normal dry-storage use. Risk only emerges if the box is physically fractured or exposed to prolonged UV degradation over many years, neither of which is typical for a marine dry box kept in use.
Waterproof sealant composition (PFAS in gasket/seal)
Waterproof gaskets and rubber seals in marine equipment sometimes contain PFAS to improve water resistance. Wise has not disclosed the sealant material; contact the brand to confirm non-fluorinated rubber or silicone gaskets.
Lead or cadmium in plastic colorants
Rotomolded PE for outdoor marine products typically uses pigments compliant with FDA and EU plastic standards. No contamination history is on record for Wise products in this category.
Metal hardware corrosion and leaching
Latches and hinges on marine dry boxes are often zinc-plated steel or aluminum. In saltwater environments, corrosion can release trace zinc or aluminum into stored contents over years of use; inspect hardware regularly and replace corroded parts.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 65% 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.
