Wholesale sunglasses

When evaluating sunglasses, focus on Lens Material (TAC Polarized, PC, or CR-39) and Frame Material (Acetate, TR90, or Metal). TAC Polarized lenses are essential for glare reduction, while TR90 frames offer superior flexibility and durability. Ensure the hinge quality is high, preferably using reinforced metal hinges or spring hinges for better fit and longevity.

Compliance is critical for cross-border trade. For the US market, products must meet FDA 21 CFR 801.410 (Drop Ball Test) for impact resistance and ANSI Z80.3. For the EU, CE Marking and compliance with EN ISO 12312-1 are mandatory. Always verify that the lenses provide 100% UV400 protection, blocking both UVA and UVB rays.

Request a pre-shipment inspection (PSI) and ask for third-party lab test reports (SGS or Intertek). Check for optical clarity to ensure no distortion and verify color consistency across the batch. For high-end acetate frames, ensure the polishing is smooth with no visible mold lines or burrs.

Most professional suppliers on Made-in-China.com offer OEM/ODM services. This includes laser-engraved logos on the lenses or temples, customized packaging (hard cases, microfiber pouches, and branded boxes), and the ability to choose specific Pantone colors for frames with a minimum order quantity (MOQ) usually ranging from 300 to 1,200 pieces per style.

The primary risks include intellectual property (IP) infringement and quality inconsistency. Avoid products that mimic protected brand designs to prevent customs seizures. To mitigate quality risks, use Secure Payment services and clearly define AQL (Acceptable Quality Level) standards in your purchase contract.

Negotiate based on volume tiers and long-term partnership potential. Ask for tiered pricing (e.g., 500, 1000, and 5000 units). You can often reduce the unit price by 10-20% by committing to a larger annual volume or by optimizing packaging dimensions to reduce shipping costs.

Sunglasses are lightweight but fragile. Use double-walled corrugated export cartons and ensure each pair is in a protective polybag or individual box. For large orders, Sea Freight (LCL/FCL) is most economical, but for high-value or seasonal trends, Air Freight or Express (DHL/FedEx) is preferred to reduce lead times. Always confirm the Incoterms (e.g., FOB or DAP) before finalizing the deal.

Always source from Audited Suppliers on Made-in-China.com who have undergone third-party verification. Utilize Trade Messenger to keep all communication records on-platform and prefer suppliers with high trust scores and a history of exporting to your target region.
