Brand sunglasses

When evaluating sunglasses, the most critical technical factor is UV Protection, specifically UV400 rating, which blocks 99-100% of UVA and UVB rays. For lens materials, Polycarbonate is preferred for impact resistance, while TAC (Triacetate Cellulose) Polarized lenses are essential for reducing glare in driving or water sports scenarios. Frame materials should be assessed based on use-case: TR90 (Thermoplastic) offers superior flexibility and lightweight comfort, whereas Acetate is the gold standard for premium, hand-polished aesthetics and durability.

Compliance is non-negotiable in the eyewear industry. For the US market, products must comply with FDA 21 CFR 801.410 (Drop Ball Test) for impact resistance and ANSI Z80.3 standards. For the European Union, sunglasses must carry the CE Mark and meet EN ISO 12312-1 requirements. Additionally, ensure all materials are REACH compliant to guarantee they are free from harmful chemicals like lead or phthalates.

A professional buyer should request an ISO 9001 certification to ensure consistent quality management. For 'Brand' level products, look for suppliers who offer detailed QC reports covering hinge durability (cycle testing), salt spray tests for metal components to prevent corrosion, and lens coating adhesion tests. It is highly recommended to source from verified manufacturers on Made-in-China.com who have undergone on-site audits.

Suppliers usually offer laser-engraved logos on the lenses or temples, customized silk-screen printing, and bespoke packaging including branded hard cases, microfiber cloths, and authenticity cards. For high-volume orders, you can request custom mold development to create unique frame shapes that differentiate your brand from competitors.

When sourcing 'Brand' sunglasses, ensure you are not infringing on existing trademarks. If you are producing your own brand, register your trademark in both the manufacturing country and the destination country. If purchasing established brands, strictly verify the Letter of Authorization (LOA) from the brand owner to avoid customs seizures and legal disputes.

Focus on the Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for lower MOQs on trial orders to test market response, and request tiered pricing where the unit cost drops as volume increases. Always clarify Incoterms (e.g., FOB or DAP) and ensure the supplier provides spare parts (like screws and nose pads) at no extra cost, typically 1-3% of the order volume.

Sunglasses are prone to pressure damage. Insist on double-walled corrugated export cartons and ensure each unit is protected by a bubble bag or individual retail box. For high-value branded goods, Air Freight is recommended to reduce handling time and the risk of theft, though Sea Freight remains the most economical choice for bulk shipments exceeding 500kg.

To ensure payment safety, use secure payment escrow services provided by reputable platforms like Made-in-China.com. Never wire full payments upfront; a standard industry practice is a 30% deposit to start production and the 70% balance payable after a successful third-party pre-shipment inspection (PSI).
