AI-Powered supplier vetting

SummaryWellgreen Technology Co., Ltd. is identified as a professional technical supplier with technical research and development activities, customization, ODM, and OEM capabilities. It reports new products within the past year and operates two production lines, but has fewer than five quality-control staff and only three years of stated R&D-engineer experience. The supplier has inventory capability and documented procedures for evaluating service suppliers, with stated lead times within 15 working days in both peak and off-season. However, the provided information indicates no 3D software design service, SDK availability, overseas agents or branches, overseas warehouse, overseas showroom, or offline trade-show participation. No valid manufacturing-capacity contract with associated subcontractors is reported. Financial records are referenced for 2021–2023, but no financial figures are provided. Customer-related evidence is limited to OEM service for well-known brands, without named cases.

Supplier typeThe supplier is explicitly described as a professional technical supplier and conducts technical R&D. Its stated business scope includes veterinary drugs, cosmetics, pharmaceutical intermediates, chemical and biological products, technical R&D, and import/export activities. The company is identified as Wellgreen Technology Co., Ltd., located in Xi'an High-Tech Zone.

R&D capabilityThe supplier is identified as a professional technical supplier, reports three years of total R&D-engineer experience, launched new products within the past year, and provides ODM services. It explicitly does not provide 3D software design services and has no available SDK, so its innovation capability is demonstrated mainly through product R&D and design-manufacturing services rather than software or SDK development.

Production capacityThe supplier operates two production lines, reports inventory capability, and states average lead times within 15 working days during both peak and off-season. At the same time, it reports no valid manufacturing-capacity contract with associated subcontractors, while quality-control staffing is below five people; these constraints should be considered when evaluating scale and production governance.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, flexible customization, and minor customization. It also provides ODM services and OEM services for well-known brands, supporting a broad customization and design-manufacturing offering.

Client casesThe supplier states that it provides OEM services for well-known brands, which is evidence of experience serving established-brand customers. However, no customer names, project details, product examples, or independently verifiable case studies are provided.
