Stock optical frames manufacturers

When sourcing stock optical frames, material integrity is paramount for durability and skin safety. For Acetate frames, ensure they are hand-polished rather than injection-molded to prevent color fading. For Metal frames, prioritize Monel or Stainless Steel for corrosion resistance, and verify that Nickel-free plating is used to avoid allergic reactions. If sourcing TR90 frames, check for high flexibility and memory retention, ensuring the frames return to their original shape after bending.

Optical frames are classified as medical devices in many regions. You must ensure products meet ISO 12870:2016 standards for ophthalmic optics. For the US market, FDA Registration and UDI (Unique Device Identification) are mandatory. For the EU, frames must carry the CE Mark and comply with the Medical Device Regulation (MDR) 2017/745. Always request Declaration of Conformity and Lead-free test reports before finalizing a purchase.

The hinge is the most common point of failure. Look for OBE or Comotec hinges for premium stock, or at least reinforced 3-barrel or 5-barrel hinges. Ask the supplier for cycle test data, specifically looking for frames that have passed 20,000+ opening and closing cycles. Additionally, ensure the bridge width and temple length follow standard sizing (e.g., 52-18-140) to ensure a universal fit for your target demographic.

Purchasing Stock Optical Frames offers the primary advantage of Low Minimum Order Quantities (MOQ), often as low as 12-50 pieces per color, and immediate shipment (usually within 3-7 days). This is ideal for testing market trends without heavy capital investment. However, ensure the stock is not 'dead stock' by verifying that the styles align with current eyewear trends like oversized geometric shapes or transparent crystal acetates.

Stock items are sometimes overruns or cancelled orders. To protect yourself, hire a third-party inspection service to conduct a Pre-Shipment Inspection (PSI). Focus on surface scratches, lens groove consistency, and temple alignment. Use Made-in-China.com's Secured Trading services to ensure payment is only released once the inspection report is approved.

Don't just negotiate on unit price; negotiate on packaging and accessories. Ask the supplier to include microfiber cleaning cloths and hard cases at a bundled rate. For bulk orders exceeding 500 pieces, negotiate for free laser-branding of your logo on the inner temple, which adds significant brand value to stock items.

Eyewear is fragile and prone to pressure damage. Insist on individual polybags for each frame, packed in inner boxes of 10-20 units, and finally housed in double-walled corrugated export cartons. Ensure the gross weight per carton does not exceed 15kg to prevent crushing during stacking in sea or air freight.

Be aware that some countries impose Anti-Dumping Duties on glassware and frames from specific regions. Check your local Harmonized System (HS) Code (typically 9003.11 or 9003.19) against trade remedy databases. Consult with a licensed customs broker to determine if your shipment will be subject to additional tariffs, which can significantly impact your Total Cost of Ownership (TCO).
