AI-Powered supplier vetting
SummaryThe supplier is identified as a combined company with three production lines and stated output for calcined alumina powder, alumina ceramic grinding balls, and spray-dried alumina powder. It provides 3D software design, ODM, OEM, and multiple customization options, but reported no new products in the past year and no available SDK. Quality and service processes are documented, including finished-product inspection, supplier-service assessment, corrective/preventive actions, and complaint handling. Export experience is stated at 16 years, while overseas service infrastructure is limited: no overseas warehouse, showroom, agent, branch, or offline trade-show participation. The provided information does not establish certifications, financial credibility, or identifiable customer cases.
Supplier typeThe supplier is explicitly classified as a “Combined” company and is not identified as an offshore company. This indicates a combined business type, but the slices do not provide further legal or ownership detail.
After-Sales capabilityThe supplier has written procedures and records for service-capability assessment, corrective and preventive actions, and customer complaints. However, it has no overseas warehouse, showroom, agent, branch, or stated overseas service coverage, so the evidence supports structured service handling but not broad overseas after-sales infrastructure.
