Sunglasses with ce certification manufacturers

To legally carry the CE mark, sunglasses must comply with EN ISO 12312-1:2013/A1:2015. This standard dictates requirements for optical quality, luminous transmittance, and UV protection. You must ensure the supplier provides a Declaration of Conformity (DoC) and that the products are categorized by filter type (0 to 4), with Category 3 being the most common for general purpose sun protection.

B2B buyers should demand UV400 protection, which means the lenses block 99% to 100% of UVA and UVB rays up to 400 nanometers. Request spectrophotometer test reports from the supplier. High-quality lenses should be made of Polycarbonate (PC) or TAC polarized material to ensure impact resistance and visual clarity without distortion.

For premium markets, Handmade Acetate is preferred for its deep colors and durability. For high-volume promotional or retail orders, TR90 (thermoplastic polyamide) is excellent due to its flexibility and lightweight properties. If targeting the budget segment, PC (Polycarbonate) frames offer the lowest cost but are less flexible. Always check for nickel-free plating on metal components to prevent skin allergies.

For sports and outdoor activities, prioritize wraparound designs with anti-slip rubber nose pads and temple tips. For driving, ensure the lenses are not 'Category 4' (which are too dark for road use) and recommend polarized lenses to reduce glare from flat surfaces. For fashion retail, focus on seasonal trends like oversized frames or gradient tints while maintaining the CE safety markings on the inner temple.

Many suppliers use a 'China Export' logo that mimics the CE mark. To mitigate this risk, request the CE certificate issued by a notified body and verify the certificate number on the issuing agency's website. Ensure the factory name on the test report matches the business license of your supplier. You can find verified manufacturers with authentic certifications on Made-in-China.com.

Beyond the unit price, negotiate the MOQ for custom branding (logo printing), which usually starts at 300-500 pieces. Ask for inclusive pricing that includes protective packaging (microfiber pouches and hard cases), as these add significant value to the retail offer. Request a 2%-3% spare parts allowance for hinges and screws to handle minor defects without needing returns.

For high-value acetate frames, Air Freight is recommended to minimize the time spent in humid shipping containers which can warp frames. For large sea freight orders, ensure the supplier uses double-walled corrugated export cartons and internal dividers. Always use Incoterms like FOB (Free On Board) to maintain control over the shipping costs and insurance through your own forwarder.

Never send full payments upfront to new suppliers. Use Escrow-based payment services or Letters of Credit (L/C) for large volumes. On Made-in-China.com, look for Audited Suppliers who have undergone on-site inspections by third-party agencies like SGS or TÜV Rheinland to ensure the factory actually exists and has the capacity to produce your order.
