Sunglasses fashion manufacturers

When evaluating fashion sunglasses, prioritize UV400 protection, which ensures the lenses block 99% to 100% of UVA and UVB rays. For lens materials, Polycarbonate (PC) is preferred for impact resistance, while TAC (Triacetate Cellulose) is ideal for polarized lenses to reduce glare. Frame materials should range from high-grade Acetate for premium feel and durability to TR90 for lightweight flexibility and comfort.

Compliance is critical for cross-border trade. For the US market, products must meet FDA 21 CFR 801.410 (impact resistance/drop ball test) and ANSI Z80.3. For the European Union, sunglasses must carry the CE mark and comply with EN ISO 12312-1. Additionally, ensure materials are REACH compliant to verify the absence of harmful chemicals like lead or phthalates.

Request a Pre-Shipment Inspection (PSI) focusing on the hinge durability (minimum 5,000 cycles), coating adhesion (cross-hatch test for mirrored lenses), and optical clarity to ensure no distortion. It is highly recommended to source from suppliers on Made-in-China.com who provide third-party lab test reports (SGS or TUV) for lens transmittance and frame stability.

Most professional suppliers offer laser-engraved logos on the temples or lenses, customized packaging (microfiber pouches and hard cases), and private labeling. For high-volume orders, you can request custom pantone colors for frames and specific lens tints (gradient, mirrored, or photochromic) to align with current seasonal trends.

Sunglasses are fragile; ensure the supplier uses double-walled corrugated export cartons and individual bubble wrap or protective sleeves for each unit. Negotiate FOB (Free On Board) terms to have better control over the logistics provider and consider cargo insurance to cover potential breakage during long-haul sea or air freight.

Focus on tiered pricing based on volume; for example, a 15-20% discount is standard when moving from a 500-unit MOQ to 2,000 units. Discuss sample fee refunds where the cost of the sample is deducted from the final bulk order. Always clarify the lead time, which typically ranges from 25 to 40 days for customized fashion eyewear.

Utilize Secured Trading Services provided by platforms like Made-in-China.com to ensure payments are only released upon confirmation of shipment. Always verify the supplier's Audit Report and Business License to confirm they are a legitimate manufacturer rather than a small trading intermediary, which ensures better after-sales accountability.

For North America, ensure the supplier is FDA registered, as customs may hold shipments without proper medical device listing numbers. For Europe, ensure the Declaration of Conformity (DoC) is included in the shipping documents. Using DDP (Delivered Duty Paid) shipping can simplify the process for new buyers by including all customs duties and import taxes in the upfront shipping cost.
