Eyewear OEM Frames 2026: Quality Inspection Standards & MOQ Guide | SCM Group HK

For brands and importers sourcing OEM eyewear frames from China in 2026, navigating quality inspection protocols and minimum order quantities (MOQ) is as important as design. The Chinese optical frame manufacturing sector spans acetate, TR90, titanium, and metal alloy materials — each with distinct quality verification requirements. MOQ for custom OEM development typically starts at 300 units per model, though some manufacturers offer trial runs at lower quantities for prototyping and market testing. Understanding inspection frameworks including CE (EN ISO 12870), FDA 21 CFR Part 801, and realistic MOQ structures ensures your sourcing strategy is both commercially viable and market-compliant before committing to production tooling investment.

Quality Inspection Standards for OEM Eyewear Frame Procurement

China-sourced eyewear frames for export to Europe and the US must comply with EN ISO 12870 (spectacle frames general requirements and test methods) for CE marking, and FDA 21 CFR Part 801 for US import clearance. Key inspection checkpoints include: material verification confirming acetate cellulose content, TR90 flexural resistance rating, and titanium alloy grade; dimensional tolerance checks with temple length ±2mm and bridge width ±1mm; hinge durability testing at 5000 open-close cycles minimum; and surface finish inspection covering coating adhesion, chrome plating thickness, and color consistency across the production batch.

Material-Specific Verification: Acetate, Titanium & TR90

Acetate frames require verification of cellulose acetate content (typically 70–80% cellulose acetate, 20–30% plasticizer), flammability testing per EN ISO 12870, and UV stability testing. Titanium frames — increasingly demanded for premium segments — require XRF spectrometer verification to confirm Grade 1 pure titanium or Grade 5 Ti-6Al-4V alloy composition and absence of nickel or lead in contact surfaces. TR90 polyamide frames should be tested for impact resistance, chemical resistance to common cleaning agents, and color fastness under UV exposure. Always request material test certificates alongside physical samples before placing production purchase orders.

MOQ Strategy & Supplier Qualification Process

Standard OEM MOQ in China's optical frame sector runs 300–600 units per colorway per model for custom tooling. Leading Wenzhou and Shenzhen manufacturers offer 50–100 unit sampling runs for new customers, with tooling costs amortized into higher per-unit prices. To qualify a supplier: verify ISO 9001 or ISO 13485 certification status, request CE and FDA compliance documentation, inspect three production samples across the full specification sheet including hinge function, coating quality, and fit, and audit packaging standards for retail-ready delivery. SCM Group HK manages the complete OEM process from mold tooling through final inspection and export documentation, operating from our Hong Kong base with direct factory access in Shenzhen.
