Custom Eyewear Frames 2026: Quality Verification & MOQ Guide for OEM Buyers | SCM Group HK

Sourcing custom eyewear frames from Chinese OEM manufacturers in 2026 requires clear understanding of quality verification protocols and minimum order quantity thresholds by material type and production method. The Chinese eyewear manufacturing sector — concentrated in Wenzhou, Xiamen, and Shenzhen — produces an estimated 300–500 million frames annually, with exports dominated by acetate, TR90 (Grilamid), titanium, and stainless steel alloy frames. MOQ structures vary significantly: OEM logo customization on in-stock base models starts from 300 pieces per design with 3–7 day lead times, while ODM new mold development requires 600–1,000+ pieces per model. SCM Group HK specialises in custom eyewear frame sourcing for international optical brands, distributors, and retailers, connecting buyers with verified Wenzhou and Shenzhen manufacturers and managing quality inspection, compliance documentation, and export logistics from Hong Kong.

Material Selection: Acetate vs. TR90 vs. Titanium

Each frame material has distinct quality verification checkpoints and brand positioning implications. Acetate (cellulose acetate) is valued for colour depth, pattern complexity, and premium feel — quality checks focus on delamination resistance, hinge reinforcement quality, and finish consistency across batch. TR90 (Grilamid) offers lightweight flexibility and chemical resistance — key QC points are weld-line strength, surface gloss uniformity, and colour batch matching. Pure titanium (grade 1 or 2) commands the highest price premium — quality verification covers weld seam integrity, anodising adhesion, nose pad alignment, and spring hinge function. For 2026, sustainability-oriented buyers increasingly specify bio-acetate alternatives, which require additional raw material certification from the manufacturer.

MOQ and Production Timeline Guide for 2026

MOQ requirements for 2026 OEM eyewear frame orders in China: in-stock model OEM (logo only) — 300 pcs/design, 3–7 working days; TR90 ODM (new mold) — 500–800 pcs/colour, 30–45 working days; acetate ODM (new mold) — 600–1,000 pcs/colour, 45–65 working days; metal ODM — 500+ pcs, 75–90 working days. Manufacturers producing 300,000–500,000 frames/month can accommodate parallel orders across multiple SKUs. For smaller brands entering the market, shared-mold arrangements for TR90 can bring minimum quantities to 200–300 pcs with a 10–15% unit cost premium. SCM Group HK negotiates MOQ flexibility and production slot priority for international buyers based on consolidated order volume.

Quality Verification Protocol for OEM Eyewear Frames

SCM Group HK applies a structured quality verification process for all eyewear frame orders: (1) Pre-production material confirmation — raw material COA (Certificate of Analysis) for acetate grade, TR90 compound specification, or titanium purity; (2) First article inspection — dimensional check against approved tech pack, weight, hinge torque, temple spring function, and colour reference; (3) In-line production inspection at 30–50% completion for orders above 500 pieces; (4) Final random inspection (AQL 2.5, Level II) before shipping; (5) REACH/RoHS compliance documentation for EU-bound orders and FDA 21 CFR compliance for US-bound eyewear. All inspection reports are shared with the buyer before release of shipping payment.
