AI-Powered supplier vetting

SummaryThe supplier is a Tianjin-based factory and limited company with 24 employees, offering zircon sand and flour, zirconium silicate, rutile, ilmenite, and kyanite. It has export experience of two years, reports that 51%–70% of sales are exports, and holds self-operated import and export rights. The supplier supports customization from samples and OEM service for well-known brands, but does not provide 3D software design, ODM, SDK, overseas warehouses, overseas showrooms, or overseas agents and branches. It has participated in a 2025 Turkish industrial exhibition. Quality assurance, complaint handling, corrective and preventive action procedures, and supplier assessment procedures are documented and followed, although finished-product inspections have instructions but no written records. Financial information is inconsistent across the provided records and does not support a reliable assessment. No formal certifications or specific customer cases are identified.

Supplier typeThe supplier is identified as a factory and a limited company located in Tianjin’s Jinnan District. It is not part of a larger company group, has 24 employees, and is associated with wholesale and retail industry information.

After-Sales capabilityThe supplier reports clear procedures and followed records for handling customer complaints, corrective and preventive actions, and quality assurance in quality-control processes. These records support an after-sales and quality-response capability, although no specific response times or service outcomes are provided.

R&D capabilityThe supplier states that it is not a professional technical supplier, has not launched new products in the past year, does not provide 3D software design or ODM services, and has no available SDK. These explicit limitations indicate weak innovation and formal R&D capability.

Production capacityThe supplier is a factory with 24 employees, has 15 qualified suppliers for the relevant service capability, and reports peak- and off-season lead times within 15 working days. It also reports quality assurance and documented supplier assessment procedures, but finished-product inspection instructions lack written records.

Customization capabilityThe supplier explicitly provides customization from samples and offers OEM service for well-known brands. However, it does not provide ODM services or 3D software design, so its customization capability is sample-based rather than supported by broader design-development services.
