Sunglasses Manufacturer and Sourcing Partner in China

Minimum Order Quantities depend directly on frame materials and structural customization. Ready-to-brand stock frames typically require low MOQs starting at 100 to 300 units per style. Conversely, bespoke frame geometries, custom injection colors, or specialized acetate fabrications usually start at 1,000 units per colorway due to factory mold setup costs.

Vela Sourcing maintains upfront transparency regarding MOQs, sample development costs, and lead times to prevent downstream purchasing misalignments. We audit supplier networks across China to match production lines directly with your specific batch targets and scaling budget.

Selecting the right optical profile depends on your target market, sales channel, and target retail price point. Polarized lenses command higher retail price margins and are ideal for outdoor performance, sports, fishing, and driving brands where glare reduction is critical. Standard TAC or PC UV400 lenses offer complete UVA/UVB protection and are highly cost-effective for fast-fashion, lifestyle, and promotional collections.

Our team assists eCommerce brands and distributors in balancing lens material costs (such as CR-39, Nylon, or Polycarbonate) with perceived consumer value, ensuring high profit margins without sacrificing optical clarity or UV compliance.

Private label branding can be integrated across multiple touchpoints of the product and its retail packaging. Common logo applications include outer temples (laser engraving, metallic foil stamping, or 3D raised metal badging), inner temples (silk-screen printing for brand name, model numbers, and CE/UV400 markings), left lens corner (subtle laser etching), and accessories (heat transfer or embossed logos on microfiber cloths, soft pouches, rigid clamshell cases, and shipping boxes).

We eliminate production variance through physical golden sample locking and strict technical specification documents (tech packs). Before mass production begins, a signed pre-production sample is countersigned and retained at both our local inspection office and the manufacturing facility.

During raw material procurement and assembly, our quality control inspectors conduct first-article inspections and mid-production audits to evaluate frame color consistency, temple alignment, hinge tension, and lens fit against the golden sample baseline.

Every production batch undergoes comprehensive Pre-Shipment Inspection (PSI) adhering to standard ISO 2859-1 (AQL) parameters. Our standard protocol covers cosmetic inspection (surface scratches, frame coating durability, logo clarity), structural integrity (hinge smoothness, drop-ball impact, frame alignment, screw tightness), optical compliance (spectrometer UV400 filtering and polarization axis checks), and packaging & labeling (barcode scan verification, FBA carton compliance, unboxing presentation).

Yes. Vela Sourcing manages complete kitting, packaging assembly, and warehouse consolidation before goods leave China. We coordinate custom paper boxes, leatherette cases, cleaning cloths, and barcode sticker applications into a single streamlined workflow.

By consolidating eyewear production with custom packaging in our central facility, we prevent damage, ensure packaging accuracy, and prepare full FBA or direct-to-warehouse freight consolidation.
