AI-Powered supplier vetting

SummaryNingbo Starkea Industrial Technology Co., Ltd. is a China-based manufacturer/factory and limited company with valid import/export licensing, eight years of export experience, and exports accounting for 90% of total sales. It provides OEM, ODM, and design customization services, including 3D software design, but has only one R&D engineer, no new products launched in the past year, and no available SDK. Customer complaint handling is supported by a clear procedure and follow-up records, while corrective/preventive-action procedures are not documented. Overseas service infrastructure is limited: no overseas showroom, agents, branches, or offline trade-show participation are reported. The supplier has no Fortune 500 customer history, although repeat buyers represent 50%–80%. Financial records are identified for 2022–2024, but the provided information does not disclose performance results, so financial credibility cannot be fully assessed.

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and a limited company operating in Zhejiang, China. It is not part of a larger company group and has five employees.

CertificationsThe supplier is reported to hold a valid import/export license. No other certifications or certification systems are identified in the provided information, so the assessment is limited to export licensing.

After-Sales capabilityCustomer complaints are handled through a clear procedure with follow-up records, and the supplier accepts multiple quotation and payment terms. However, it has no overseas showroom, agents, branches, or offline trade-show history, and it lacks written corrective and preventive-action procedures or records.

R&D capabilityThe supplier is identified as a professional technical supplier and provides 3D software design, ODM, and customized design services. Innovation capacity appears limited by having one R&D engineer, no new products launched in the past year, and no available SDK.

Production capacityThe supplier is a manufacturer/factory with five qualified suppliers listed for service capability, access to Ningbo, Xiamen, and Qingdao ports, and stated peak- and off-season lead times of within 15 working days to one month. However, the very small employee count and absence of production-volume data prevent a broader capacity assessment.

Customization capabilityThe supplier explicitly offers customization from designs, 3D software design services, ODM services, and OEM services for popular brands. These stated capabilities provide direct evidence of design-based customization and contract manufacturing support.
