AI-Powered supplier vetting

SummaryDongguan Caojin Technology Co., Ltd. is identified as a China-based limited company and manufacturer/factory offering multiple sink and wash-basin products. The supplier reports granite sink output of 100,000 pieces and exports to a broad range of markets, with Shenzhen identified as the nearest port and off-peak lead time within 15 working days. It has one R&D engineer, six to ten quality-control staff, and stated customization capabilities. However, the available quality-control evidence records zero test equipment, while quality assurance and traceability statuses are unknown. The supplier’s R&D information confirms new-product development but no available SDK. Financial records are represented only by years, without sufficient evidence to assess credibility. An audit by BV is documented, but the audit result is recorded as 0 and no certification is explicitly identified. No specific customer cases are provided.

Supplier typeThe supplier is identified as both a Manufacturer/Factory and a Trading Company, with a limited-company structure in China. Its stated product scope centers on granite, quartz, laundry, bathroom, apron sinks, wash basins, and niches.

After-Sales capabilityThe R&D engineer’s responsibilities explicitly include providing technical support for after-sales service, and the company description claims satisfactory after-sales service. These statements support some after-sales capability, although no service-response metrics or formal service process are provided.

R&D capabilityThe supplier reports one R&D engineer, six to ten years of total R&D-engineer experience, new products launched in the last year, and responsibilities covering new-product development and technical support. However, no SDK is available, so the evidence supports product-development activity but not SDK-based development capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its company description also states that its R&D team designs customized products according to customer needs.
