Eyewear Frames OEM 2026: Quality Verification Process & MOQ Guide for Acetate and Titanium Frames | SCM Group HK

China manufactures over 70% of the world's eyewear frames, making it the dominant global supplier for both OEM and private label eyewear brands. In 2026, the private label optical frame market is growing rapidly, with international brands increasingly sourcing acetate and titanium frames from Chinese manufacturers to achieve premium quality at competitive pricing. However, quality consistency and minimum order quantity (MOQ) management remain the two most critical challenges for buyers entering the Chinese eyewear supply chain. Acetate frames typically require a MOQ of 300 pieces per model in 3 colorways, while titanium frame programs start at 200–300 pieces for established designs or 500+ pieces when new CNC tooling is required. Quality verification for export-standard eyewear involves mandatory testing including 48–72 hour artificial sweat immersion tests, high-and-low temperature cycling (−40°C to +80°C), UV resistance testing, and hinge durability testing (typically 100,000 open-close cycles per EN ISO 12870). SCM Group HK manages end-to-end OEM eyewear frame sourcing with full QC oversight from material to shipment.

MOQ Structure: Acetate vs Titanium vs TR90 Frames

MOQ structures vary significantly by frame material and design complexity. Acetate frames — the premium frame material of choice for fashion eyewear — have a well-established production ecosystem in Wenzhou and Shenzhen, allowing entry MOQs of 100–300 pieces for in-stock sheet colors. Custom acetate color development (unique patterns or laminated sheets) requires 500+ pieces and 45–60 days for material development lead time. Titanium frame programs are more complex: pure titanium (Grade 1–4) and beta-titanium require specialized CNC machining, TIG welding, and multi-stage surface finishing — MOQs typically start at 200–300 pieces even for standard shapes, rising to 500+ for fully custom designs. TR90 (nylon-based thermoplastic) injection-molded frames offer the most accessible entry point at MOQs of 100 pieces with 14–21 day lead times for existing mold designs. For brands entering OEM eyewear for the first time, TR90 or stainless steel frames using existing tooling are the recommended low-risk starting point.

Quality Verification Process: Three Critical Checkpoints

A robust quality verification workflow for eyewear OEM orders consists of three mandatory checkpoints. First, pre-production material verification: confirm acetate sheet thickness (6–8mm standard), material source certification (premium benchmarks include Mazzucchelli and Eastman acetate), and color accuracy under D65 standard illuminant against approved samples. Second, in-process quality inspection: check hinge installation torque (standard range 0.8–1.2 N·m), temple arm alignment tolerance (±0.5mm), and lens rim aperture accuracy (±0.3mm for optical mount frames). Third, pre-shipment final inspection per EN ISO 12870: mechanical strength tests, flammability classification (UL94 HB minimum for frame materials), and nickel release testing (≤0.5μg/cm²/week maximum) for any metal components in skin contact — mandatory for EU market compliance.

Custom Branding, Packaging & Export Market Compliance

Brands entering EU, US, or Japanese markets must navigate additional regulatory requirements beyond basic product quality. EU market entry requires CE marking under EN ISO 12870 for optical frames; sunglasses additionally require EN ISO 12312-1. In the US, ANSI Z80.5 applies to prescription frame standards. Japan requires testing at JIS-accredited labs. On the branding side, OEM buyers should specify: laser engraving or heat-stamp logo placement on temples (minimum depth and legibility requirements), case and cleaning cloth specifications, hang tag and retail barcode format (EAN-13 or UPC-A), and country-of-origin marking compliance per importing country customs rules. SCM Group HK supports the full OEM cycle — factory selection, sample development, QC inspection coordination, and export documentation preparation.
