Eyewear Frames OEM 2026: Quality Verification, MOQ & Lead Times for Custom Acetate, Titanium & TR90 | SCM Group HK

For optical retail chains, private label brands, and distribution groups sourcing custom eyewear frames from China in 2026, understanding the actual quality verification process and minimum order quantity (MOQ) structures is essential for risk management and profitable margin control. China manufactures approximately 70% of the world's eyewear frames, with production concentrated in Wenzhou, Danyang, and Shenzhen. The three dominant frame materials - cellulose acetate, beta-titanium, and TR90 (a thermoplastic polyamide elastomer) - each carry different production lead times, MOQ thresholds, and quality verification requirements. Wholesale MOQ typically starts at 300 pieces per style for stock frames, while custom OEM/ODM orders generally require 500-1,000 pieces per style depending on material complexity. Lead times for custom acetate frames run 45-60 working days from design approval; titanium frames require 75-90 working days due to precision CNC machining and multi-stage surface treatment.

Quality Verification Standards for OEM Eyewear Frames

Quality verification for custom OEM eyewear frames covers three stages: incoming material inspection, in-process quality control, and final pre-shipment inspection. For acetate frames, incoming inspection checks sheet thickness tolerance (+/-0.1mm), color consistency (Delta-E <= 1.5 by spectrophotometer), and moisture content. In-process checks verify dimensional accuracy against CAD drawings (tolerance +/-0.2mm) and hinge alignment. For titanium frames, critical checks include weld strength testing on temples (minimum 30N pull force), surface finish verification (roughness Ra <= 0.4um for polished surfaces), and anodizing adhesion. Final pre-shipment inspection per AQL 2.5 Level II covers cosmetic defects, optical center alignment, spring hinge function, and temple spread force (15-20N for comfort-fit). Third-party inspection by SGS, Bureau Veritas, or Intertek can be arranged at our partner factories.

Acetate vs. Titanium vs. TR90: Material Selection for OEM Orders

Each frame material serves a distinct market position in 2026. Cellulose acetate remains the premium choice for fashion optical collections - unlimited color and pattern options, natural luster, premium hand-feel, but higher per-unit cost (USD 8-25 EXW). Beta-titanium frames deliver ultra-lightweight performance (as low as 2.7g per pair) with hypoallergenic properties and superior corrosion resistance - ideal for premium European collections (USD 15-40 EXW). TR90 injected frames provide the best price-performance ratio for children's lines, sports optical, and value collections (USD 3-8 EXW), with natural flexibility and impact resistance that reduces breakage complaints. SCM Group sources OEM eyewear across all three material categories with verified factory partners in Wenzhou and Danyang.

MOQ, Lead Time and Logistics for China Eyewear OEM

After design approval, first sample production takes 15-20 working days; second sample corrections add 7-10 days. Mass production commences after sample sign-off. For sea freight from Ningbo or Shanghai to Europe (approximately 30 days transit), total door-to-door lead time for an acetate OEM order averages 85-110 working days. For air freight, delivery reduces to 55-75 working days at higher logistics cost. Typical EXW pricing at MOQ 500pcs/style: acetate USD 12-22, titanium USD 18-35, TR90 USD 4-7. FOB pricing adds approximately USD 0.80-1.20 per frame. SCM Group manages the full supply chain from Wenzhou factory to your warehouse - factory selection, sample management, quality inspection, and Hong Kong export documentation.
