Tr90 frame manufacturers

TR90 is a Swiss-developed thermoplastic material known for being incredibly durable, flexible, and lightweight. For commercial sourcing, the primary advantages are its shape memory property (allowing frames to bend under pressure and return to their original shape) and its hypoallergenic nature, which significantly reduces customer returns related to skin irritation or frame breakage.

To ensure market access and consumer safety, buyers must verify that suppliers comply with ISO 12870 (Ophthalmic optics - Spectacle frames). For the US market, FDA Registration is mandatory as eyewear is classified as a medical device. For the EU, CE Marking and compliance with REACH regulations (ensuring no harmful chemicals like lead or cadmium are present) are essential.

Authentic TR90 has a distinctive lightness (about 85% of the weight of traditional plastics) and a high heat resistance (up to 350 degrees). Buyers should request a flexibility test report; genuine TR90 can withstand extreme bending without snapping. Additionally, check the surface finish—high-quality TR90 should have a smooth, skin-friendly texture without visible injection molding seams.

Most professional manufacturers on Made-in-China.com offer private labeling (logo printing) via laser or silk screen. Advanced customization includes custom color injection (Pantone matching), adjustable nose pads, and interchangeable temple tips. For high-volume orders, you can request custom mold development to create proprietary designs.

The most significant risk is material substitution, where suppliers mix TR90 with cheaper PC (Polycarbonate) to lower costs. This results in frames that are brittle and prone to breaking. To mitigate this, always request a pre-shipment sample and consider a third-party lab test to verify the polymer composition.

Standard MOQs for TR90 frames usually range from 300 to 500 pieces per color. To optimize costs, negotiate a tiered pricing structure where the unit price drops by 10-15% as volume increases. If you are a startup, look for suppliers on Made-in-China.com that offer 'Ready to Ship' items with lower MOQs (e.g., 12-50 pieces) to test the market first.

Eyewear is sensitive to pressure. Ensure the supplier uses individual polybags and bubble wrap for each frame, packed into double-walled corrugated export cartons. For shipping to the US or Europe, Air Freight is recommended for high-value designer frames to ensure fast turnover, while Sea Freight (LCL) is more cost-effective for bulk promotional orders.

Always use Secured Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released after you confirm receipt of goods. Additionally, prioritize Audited Suppliers who have undergone on-site inspections by third-party agencies like SGS or Bureau Veritas to verify their production capacity and business legitimacy.
