Nikon WP-CP5 Marine Case for Camera
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes waterproof polymer case, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Gasket/seal leachables
Rubber gaskets (often nitrile, neoprene, or silicone) can off-gas volatile compounds if stored in heat or sunlight, but this occurs inside an unoccupied case and poses no inhalation risk. No brand-specific recalls or complaints on record.
Mold and bacterial growth in damp conditions
If the case is sealed while wet or stored in high humidity without ventilation, foam lining and gaskets can support mold. This is a maintenance issue, not a formulation hazard, and is mitigated by drying before storage.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Microplastics
EVA or polyethylene foam lining may shed fibers if compressed or crushed, but only in dust form within the sealed case, not into water or food. No migration into camera equipment has been reported.
Source, EPA ↗Polymer degradation and microplastic shedding over time
Polycarbonate and polypropylene are dimensionally stable in dry, temperate conditions. Degradation sufficient to release microplastics requires years of UV exposure or heat cycling well above typical storage conditions.
Heavy metals
If the case contains zinc alloy or chrome-plated steel hardware, no lead or cadmium contamination is reported for this product line. Nikon does not disclose metal alloy specs, so assume compliance with RoHS (lead-free) as standard for consumer electronics accessories.

What it's made of and why it matters
The WP-CP5 is a rigid thermoformed or injection-molded polymer case, likely polycarbonate or polypropylene based on Nikon's product line conventions for waterproof protection. Rigid polymers in sealed cases do not leach into water or food and avoid the BPA/phthalate migration risks associated with flexible plastics or repeated heating. The interior is typically lined with foam padding (polyethylene or EVA foam), which is chemically stable and inert when dry. Seals are mechanical (gaskets, latches) rather than coating-based, so no volatile organic compounds or degrading surface treatments are involved.
The brand's record and disclosure
Nikon has not published explicit PFAS or chemical disclosure statements for the WP-CP5, which is typical for camera accessory manufacturers. The brand does not have a documented history of chemical recalls in protective cases. Nikon's parent company operates under Japanese chemical regulation, which does not mandate PFAS labeling for non-food contact goods, but absence of public concern suggests no known formulation issues. No third-party certifications (e.g., SGS, Bluesign) are claimed, as these are uncommon for camera cases.
How it compares in its category
The WP-CP5 is a mid-to-premium option in the rigid waterproof case category. Cheaper alternatives (often soft neoprene or fabric pouches) pose microplastic shedding and mold growth risks if stored damp; the hard case avoids both. More expensive military-grade cases (Pelican, Storm Case) use identical polymer chemistries and sealing methods, with no safety advantage. Nikon's case prioritizes simplicity over added coatings or treatments, reducing the variable risk profile compared to branded cases marketed with antimicrobial or UV-protective surface treatments.
If you buy it
Rinse the exterior after saltwater exposure to prevent corrosion of any metal hinges or latches. Store in a cool, dry place; polycarbonate can become brittle if exposed to prolonged UV sunlight or extreme heat, though normal indoor/vehicle storage poses no risk. Inspect gaskets annually for cracks or drying; replace if visible damage occurs. Do not submerge sealed cases containing electronics for durations longer than specified (typically 1-2 hours for camera cases), as gasket integrity degrades over many cycles and dive-equivalent pressure can exceed the rated IP rating.
