Sunglasses products

For the US market, sunglasses must comply with FDA 21 CFR 801.410 (impact resistance/drop ball test) and ANSI Z80.3. For the EU market, products must carry the CE mark and meet EN ISO 12312-1 standards. Ensuring your supplier provides Declaration of Conformity (DoC) and test reports from accredited labs is non-negotiable to avoid customs seizures.

Prioritize lenses labeled as UV400, which block 99-100% of UVA and UVB rays. You should request spectrophotometer test reports from the supplier. For performance-oriented brands, verify if the lenses are TAC polarized to reduce glare and check for optical Class 1 rating to ensure no visual distortion.

For frames, Handmade Acetate is preferred for premium collections due to its deep color and hypoallergenic properties, while TR90 (Thermoplastic) is ideal for sports eyewear because of its flexibility and lightweight nature. For metal frames, ensure they are nickel-free to prevent skin irritation and use stainless steel or titanium for corrosion resistance.

For lifestyle/fashion, focus on aesthetic finishes like gradient tints or mirror coatings. For outdoor/sports, look for anti-saltwater coatings, hydrophobic treatments, and adjustable rubber nose pads. For driving, polarized lenses are a critical requirement to eliminate road surface reflections.

Always implement a Pre-Shipment Inspection (PSI) using AQL 2.5/4.0 standards. Focus on checking hinge tension, lens scratches, and frame alignment. Using Made-in-China.com's Secured Trading Service can provide an extra layer of payment protection until the quality is verified.

Negotiate based on Total Cost of Ownership (TCO). Instead of just pushing for the lowest unit price, ask for free customized packaging (cases/cloths) or a 1-2% spare parts allowance (screws, nose pads). For long-term partnerships, request exclusivity on specific private-mold designs to maintain your market edge.

Sunglasses are high-volume but fragile. For air freight, ensure the use of double-walled corrugated master cartons with internal dividers. For sea freight, use desiccant silica gel packs inside the packaging to prevent mold on cases or oxidation on metal parts caused by high humidity during transit.

Avoid products that are 'too similar' to luxury brands to prevent customs infringement issues. If you are doing OEM/ODM, ensure you have a signed Non-Disclosure Agreement (NDA) and verify that the supplier has the right to export the specific designs. Check for authorized laboratory certifications on Made-in-China.com to ensure the supplier is a legitimate manufacturer.
