New sunglasses

When selecting sunglasses, you must prioritize Lens Material and UV Protection. Ensure lenses are made of Polycarbonate for impact resistance or TAC (Triacetate Cellulose) for superior polarization. It is mandatory that products provide 100% UVA/UVB protection (UV400). Additionally, evaluate the Frame Material; TR90 is preferred for its memory polymer flexibility and lightweight nature, while Acetate is ideal for high-end, durable fashion pieces.

Compliance is non-negotiable in cross-border trade. For the US market, sunglasses must meet FDA 21 CFR 801.410 (impact resistance/drop ball test) and ANSI Z80.3. For the European market, products must carry the CE Mark and comply with EN ISO 12312-1. If you are sourcing for children, ensure the materials are BPA-free and meet REACH or CPSIA chemical safety standards.

Request a Polarization Test Card from the supplier to verify lens functionality. For durability, ask for Hinge Cycle Test reports (ensuring the arms can open/close 20,000+ times without failure). You should also request Salt Spray Test results for metal frames to ensure they are corrosion-resistant, especially if targeting coastal markets.

Look for suppliers on Made-in-China.com that offer Laser Logo Engraving on the lenses or temples and Customized Packaging (microfiber pouches and hard cases). Advanced buyers should inquire about Private Mold services, allowing for unique frame designs that prevent direct price competition with generic models.

The primary risk is Intellectual Property (IP) Infringement. Avoid products that closely mimic luxury brand logos or patented designs, as these will be seized by Customs. To mitigate quality risks, always order a pre-production sample and use Third-Party Inspection services (like V-Trust or SGS) to check the shipment before it leaves the factory.

Sunglasses often have a tiered pricing structure. For a new design, the MOQ is typically 300-500 pieces per color. You can negotiate a lower price by committing to a larger total volume across multiple SKUs. Always clarify if the quoted price is FOB (Free On Board), which is standard for sea freight, and ensure the packaging costs are included in the unit price.

Sunglasses are lightweight but fragile. For small batches, Air Express (DHL/FedEx) is fastest, but for bulk orders, Sea Freight (LCL) is more cost-effective. Ensure the supplier uses Double-Wall Corrugated Cartons and that each pair is protected by a bubble bag to prevent scratching and frame breakage during transit.

Always use Secure Payment Services provided by reputable platforms like Made-in-China.com. Avoid direct wire transfers to private bank accounts. Utilize Trade Audit services to verify the supplier's business license and factory location, ensuring they are a Gold Member or Audited Supplier with a proven track record.
