AI-Powered supplier vetting

SummaryHefei Wang Qin Spring Co., Ltd. is a China-based manufacturer/factory in Anhui specializing in automatic door balance system and garage door springs. It reports ISO 9001 certification, nine production lines, in-stock capability, and lead times within 15 working days in both peak and off-seasons. The supplier offers broad customization, ODM, and OEM services for popular brands, but reports no new products in the past year and has fewer than five R&D engineers. Service processes exist for corrective actions and complaints, but written records and formal assessment procedures are absent. It has no overseas warehouse, showroom, agent, branch, or stated overseas-service countries, and lacks a valid manufacturing-capacity contract with related subcontractors. Financial evidence is insufficient for a credibility assessment, while customer-case evidence is limited to OEM service for popular brands and participation in R+T Asia.

Supplier typeThe supplier is identified as a manufacturer/factory and other business entity, organized as a limited company in China, with an operating location and factory address in Anhui. This directly supports classification as a manufacturing supplier.

CertificationsThe supplier reports holding ISO 9001 certification. This is explicit evidence of a certified quality management system, although no certificate scope, issuing body, or validity details are provided.

Production capacityThe supplier describes professional production and testing equipment, strict quality control, nine production lines, inventory capability, and lead times within 15 working days in both seasons. Nevertheless, it reports no valid manufacturing-capacity contract with related subcontractors, so the overall production assessment is positive but not without a documented control gap.

Customization capabilityThe supplier explicitly offers full customization, design-based customization, sample-based customization, minor customization, flexible customization, ODM services, and OEM services for popular brands. These offerings directly support strong customization capability.
