Polarized fishing sunglasses

When sourcing, prioritize TAC (Triacetate Cellulose) for cost-effectiveness or Polycarbonate for superior impact resistance and durability. For lens colors, recommend Grey lenses for deep-sea fishing in bright sunlight to maintain natural color perception, and Amber or Copper lenses for freshwater or shallow-water fishing as they enhance contrast and depth perception against green/brown backgrounds.

Ensure the products provide 100% UVA/UVB protection (UV400) to prevent eye fatigue and long-term damage. The Polarization Efficiency should be at least 99% to effectively eliminate water surface glare. Additionally, look for Hydrophobic and Oleophobic coatings which allow water droplets and skin oils to slide off easily, maintaining clear vision during active use.

The most reliable choice for B2B buyers is TR90 (Thermoplastic Polyamide). It is lightweight, flexible, and highly resistant to salt-water corrosion and extreme temperatures. For premium lines, consider floating frames made from low-density TPX material, which prevents the loss of the product if dropped in water.

Products must adhere to regional safety standards: ANSI Z80.3 for the United States, EN ISO 12312-1 for the European Union (CE marking), and AS/NZS 1067 for Australia/New Zealand. Ensure the supplier can provide FDA registration if you are importing into the US market.

Request a Polarization Test Card with your samples or ask the supplier for a video demonstration using a spectrometer. For bulk orders, hire a third-party inspection service to perform a cross-polarization test (rotating two lenses 90 degrees to ensure they turn opaque) to confirm the filter quality.

Negotiate based on Total Landed Cost. Ask for tiered pricing (e.g., 500, 1000, and 5000 units) and request customized packaging (OEM) such as hard cases and microfiber cloths to be included in the unit price. On platforms like Made-in-China.com, you can leverage the 'Audit Reports' to identify Diamond Members who offer better stability and negotiation flexibility.

Specify double-wall corrugated export cartons and ensure each pair is individually protected by a polybag and a sturdy inner box. For high-volume orders, Sea Freight (LCL/FCL) is most economical, but ensure the Incoterms are clearly defined as FOB (Free On Board) to maintain control over the shipping costs and insurance.

Always use Secured Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released after the goods pass inspection. Avoid direct wire transfers to unknown accounts and always sign a Proforma Invoice (PI) that clearly states the defect rate tolerance (usually <2%) and refund policies.
