AI-Powered supplier vetting

SummaryWELLBOLT CO., LTD. is identified as a Chinese manufacturer/factory producing fasteners and metal products. It has professional technical, 3D design, ODM, OEM, and sample/design customization capabilities, but reported no new products in the past year and no available SDK. Service management is supported by written procedures and records for supplier assessment, corrective actions, and complaint handling. The company holds a valid import/export license and has six years of export experience, with exports representing 51%–70% of total sales. However, it reports no overseas warehouses, showrooms, agents/branches, or offline trade-show participation, and overseas service coverage is recorded as zero countries. Financial records are referenced for recent years, but no financial results are provided. Certification holdings, production scale, and customer cases are not sufficiently documented; employee count is six, but this alone does not establish production capacity.

Supplier typeWELLBOLT CO., LTD. is explicitly identified as a manufacturer/factory and as a fasteners and metal production manufacturer and exporter located in Haiyan County, Zhejiang, China. It is a limited company and is not part of a larger company group.

CertificationsThe supplier is stated to possess a valid import/export license. No other certifications are identified in the provided information, so broader certification coverage cannot be assessed.

After-Sales capabilityThe supplier has written procedures and followed records for customer complaint handling, corrective and preventive actions, and service-capability assessment. However, it has no overseas warehouse, showroom, agent or branch, and its overseas service coverage is recorded as zero countries, limiting evidence of international after-sales presence.

R&D capabilityThe supplier provides professional technical R&D support, 3D software design, ODM services, and customization from samples or designs. However, it reported no new products in the past year and no available SDK, so evidence supports design and development services but not recent product innovation.

Production capacityThe supplier is explicitly classified as a manufacturer/factory producing fasteners and metal products, with export licensing and six years of export experience. Nevertheless, the employee count is six and no production capacity, equipment, output, or throughput data is provided, preventing a full assessment of manufacturing scale.

Customization capabilityThe supplier explicitly offers customization from samples and designs, 3D software design services, ODM services, and OEM services for popular brands. These statements provide direct evidence of product and design customization capability.

Client casesThe supplier states that it provides OEM services for popular brands, which indicates experience serving brand customers. No customer names, project details, order history, or verifiable case studies are provided.
