AI-Powered supplier vetting

SummaryXuzhou Yikai Valve Co., Ltd. is described as an energy-equipment manufacturer with more than 18 years of expertise and one production line. It provides OEM services for well-known brands and offers products including vapor-recovery adaptors, loading arms, and LNG nozzle assemblies. The supplier has one R&D engineer and documented design, review, verification, and validation records, but no available SDK and no quality-control test equipment reported. Service procedures exist for supplier assessment, corrective actions, and complaints, although records are unavailable. Overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch, and no offline trade-show participation. Export experience is stated as one year with two export staff. Supplier-management-system certification is listed as NIL. Financial information is represented only by years, without sufficient evidence to assess financial credibility.

Supplier typeThe supplier is identified as an energy-equipment manufacturing company with more than 18 years of manufacturing expertise, one production line, and OEM service for well-known brands. Its product description focuses on valves, vapor-recovery adaptors, loading arms, and LNG nozzle assemblies, while export experience is stated as one year.

CertificationsSupplier-management-system certification is explicitly listed as NIL. Although the roadmap mentions TÜV Rheinland-certified IoT sensors as a future goal, this does not establish that the supplier currently holds that certification.

After-Sales capabilityThe supplier has written procedures for service assessment, corrective and preventive actions, and customer complaints, but no records are available to demonstrate implementation. It reports no overseas warehouse, showroom, agent, or branch, and lists zero countries with overseas services; therefore, documented service infrastructure is limited.

Production capacityThe supplier operates one production line and reports lead times within 15 working days in both peak and off-peak seasons. However, zero quality-control test equipment is reported, the number of quality-control staff is unavailable, and ongoing batch quantity reconciliation is not performed, indicating explicit production-control weaknesses.

Customization capabilityOEM service for well-known brands is explicitly reported. The single R&D engineer is responsible for product design drawings, technical production support, and preparing product specifications for client approval, supporting customized product development.
