AI-Powered supplier vetting
SummaryFoshan Suwei Bearing Trading Co., Ltd is a China-based limited trading company established in 2021 with three employees and no stated affiliated company. It offers dental, vacuum pump, turbocharger and other bearing-related products, and reports export sales of 71%–90% with four years of export experience. The supplier reports OEM services for well-known brands, ODM services, recent new-product activity, and broad customization options. However, it has no available SDK, no written corrective-action or customer-complaint procedures, zero stated quality-control test equipment, and unknown quality-assurance and traceability status. The provided audit record identifies BV as the auditing organization, but the audit evaluation result is recorded as 0; no certification is explicitly identified.
After-Sales capabilityThe supplier has no written procedures or records for handling customer complaints and no written corrective and preventive action procedures or records. These are explicit process deficiencies in after-sales issue handling and service quality management.
R&D capabilityThe supplier reports that it had new products during the past year and provides ODM services, which supports some product-development capability. However, it explicitly has no available SDK, so the evidence supports only a partial and not comprehensive innovation capability assessment.
Customization capabilityThe supplier explicitly reports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, providing direct evidence of broad customization support.
Client casesThe supplier explicitly states that it provides OEM services for well-known brands, which is evidence of at least some brand-customer experience. No customer names, project details, product quantities, or independently verifiable case documentation are provided.
