Sport glasses manufacturers

When sourcing sport glasses, prioritize Polycarbonate or Trivex lenses due to their superior impact resistance and lightweight properties. Ensure the frames are made of TR90 (thermoplastic polyamide), which offers high flexibility and durability under extreme temperatures. Additionally, look for hydrophilic rubber on nose pads and temple tips to ensure the glasses stay in place during heavy perspiration.

For outdoor sports, UV400 protection is a non-negotiable standard to block 100% of UVA and UVB rays. Polarized lenses are critical for water or snow sports to reduce glare, while photochromic lenses are ideal for cycling or trail running where light conditions change rapidly. Always verify the presence of anti-fog and anti-scratch coatings to maintain visual clarity and extend product lifespan.

To ensure legal entry and consumer safety, products must adhere to ANSI Z87.1 (US) or EN 166/EN 172 (EU) for impact and optical requirements. For the European market, a CE Marking is mandatory, signifying compliance with PPE Regulation (EU) 2016/425. If targeting the US, ensure the supplier is FDA registered as sunglasses are classified as medical devices.

Request third-party lab test reports covering high-velocity impact tests and optical prism deviation. For bulk orders, implement an AQL (Acceptable Quality Level) 2.5/4.0 inspection focusing on hinge tension, lens seating, and coating uniformity. It is highly recommended to source from verified manufacturers on Made-in-China.com who possess ISO 9001 certification.

The main risks include intellectual property (IP) infringement and non-compliance with safety standards. To mitigate these, avoid products that mimic patented designs from major brands and always request Declaration of Conformity (DoC) documents. Using Secured Trading Services on platforms like Made-in-China.com can protect your payment until the goods are verified.

Negotiate based on Total Cost of Ownership (TCO) rather than just the unit price. Ask for tiered pricing (e.g., discounts of 10-15% for orders over 2,000 units) and discuss OEM/ODM customization costs upfront. For long-term partnerships, request a fixed price agreement for 6-12 months to hedge against fluctuations in raw material costs like polycarbonate.

Sport glasses are high-value but fragile. Use double-walled corrugated export cartons with internal dividers. For small to medium batches, Air Freight is preferred to reduce handling risks, while Sea Freight (LCL/FCL) is more economical for large volumes. Ensure the Incoterms are clearly defined, preferably FOB (Free on Board), to maintain control over the shipping process and costs.

Never transfer funds to private bank accounts; always use corporate accounts verified by the platform. Utilize Trade Audit services provided by Made-in-China.com to verify the supplier's factory existence and production capacity. For initial orders, consider a 30% deposit and 70% balance payment after a successful pre-shipment inspection.
