AI-Powered supplier vetting

SummaryWenzhou Readsun Optical Co., Ltd. is a China-based limited company in Wenzhou, Zhejiang, identified as both a trading company and manufacturer/factory. It supplies sunglasses, reading glasses, optical frames, safety goggles, and related accessories, with exports representing 71%–90% of total sales since 2016. The supplier reports ISO 9000 certification, FDA, CE, and EN 1836:2005 approvals for products, multiple factory and production-capacity claims, staged quality testing, and flexible production-line adjustment. Evidence also supports OEM/ODM, promotional packaging, product development, and established customer relationships with named buyers. After-sales capability and financial credibility cannot be fully assessed from the provided information.

Supplier typeThe supplier is explicitly identified as a limited company and as both a trading company and manufacturer/factory. Its stated business focuses on eyewear manufacturing and supply, including sunglasses, reading glasses, optical frames, safety goggles, and accessories.

CertificationsThe supplier reports ISO 9000 certification for its management system and states that its products carry FDA, CE, and EN 1836:2005 approvals. These claims provide explicit evidence of certification and product-approval coverage, although the slices do not provide certificate numbers, validity dates, or verification records.

R&D capabilityThe supplier reports 6–10 years of R&D engineer experience and states that 10 R&D staff develop 50 new styles per month for its main product. This directly indicates ongoing product-development capacity, although the slices do not independently verify the stated figures.

Production capacityThe supplier reports a 20,000-square-meter factory with six production lines and monthly capacity of 500,000 pairs, while another description states a 12,000-square-meter factory with four lines and daily capacity of 40,000 pairs; a separate profile lists production lines as above 10. Despite inconsistent facility and line-count claims, the available evidence explicitly indicates substantial eyewear production capacity and flexible line adjustment.

Customization capabilityThe supplier states that it supports OEM/ODM, can develop products with promotional or retail packaging to customer specifications, provides samples with packaging in seven days, and can flexibly adjust production lines for urgent orders. These statements directly support product and packaging customization capability.

Client casesThe supplier states that YAMAHA, C&A, and Dollar Tree rely on its promotion-sales experience and that its products have attracted buyers in North America and Europe. These named customer references and regional buyer claims provide explicit evidence of customer cases, though no order scope, duration, or independently verified references are supplied.
