Eyewear Frames Quality Verification & MOQ Guide 2026: China OEM Sourcing Standards | SCM Group HK

China manufactures approximately 70% of the world's eyewear frames in 2026, with major production hubs in Wenzhou, Xiamen, Shenzhen, and Taizhou. For international brands and distributors sourcing custom OEM eyewear, two factors dominate procurement decisions: minimum order quantities (MOQ) and quality verification protocols. MOQ varies significantly by material and customization level — stock acetate frames can be ordered from 50 pieces per color, while fully custom OEM designs in titanium or TR90 typically start at 300–600 pairs per model. Quality standards are equally variable: top-tier factories comply with EN ISO 12312-1 (sunglasses), ANSI Z87.1 (safety eyewear), and GB 14214 (Chinese optical standard). SCM Group HK has specialized in custom eyewear frame sourcing since 2019, connecting Hong Kong and international clients with verified Wenzhou and Shenzhen manufacturers offering full OEM/ODM services from concept to certified product.

Understanding MOQ by Frame Material

MOQ requirements differ by material, as each requires different tooling and setup investment. Acetate frames — cut from Mazzucchelli or Chinese sheets — typically require 200–500 pcs per color/style for custom logo work, with stock designs starting at 50 pcs. Metal frames (stainless steel, beta-titanium) require 300–600 pcs minimum due to CNC machining setup costs. TR90 injected frames have higher tooling costs but once amortized run at 300 pcs per style. Aluminum and carbon fiber frames command 500+ pcs MOQ due to specialized machining. SCM Group HK negotiates MOQ terms on behalf of clients, often achieving 20–30% lower minimums through consolidated orders across multiple buyers.

4-Stage Quality Verification Protocol

A robust quality verification process for China OEM eyewear covers four stages. Pre-production verification confirms material certificates, color matching against Pantone/RAL standards, and prototype approval with dimensional tolerances (frame width ±1.0mm, bridge ±0.5mm). In-line inspection at 30% and 70% production completion checks hinge torque (0.3–0.8 N·m), nose pad alignment, temple arm symmetry, and surface finish (no scratches >0.1mm). Pre-shipment inspection applies AQL 2.5 sampling to verify lens fitting tolerance, UV coating adhesion (cross-hatch test per ISO 2409), and hinge durability (minimum 500 open/close cycles). SCM Group HK conducts or arranges third-party inspection at all stages for OEM orders.

Certification Requirements by Target Market

Target market determines required certification. For EU/UK, frames must carry CE marking under EN ISO 12312-1 or EN166 (safety), requiring factory Declaration of Conformity and test reports from accredited laboratories. US market requires ANSI Z87.1 for safety eyewear and FDA 21 CFR 886 for optical frames. Australia requires AS/NZS 1067. Private label brands selling through Amazon FBA additionally need third-party lab test reports (SGS, Bureau Veritas, Intertek) dated within 12 months. SCM Group HK coordinates certification testing and can arrange factory audit reports for retailer or platform compliance requirements.
