AI-Powered supplier vetting

SummaryThe supplier operates in electronic measuring instruments, intelligent instruments, industrial automation, software, vehicle-mounted devices, and related manufacturing and technology services. It offers broad customization and ODM services, but reports no new products in the past year. Production is supported by one line, 6–10 quality-control staff, and stated annual outputs for three products. CE and RoHS certifications are reported, while no factory environmental impact assessment report is available. After-sales and supplier-service controls are weakly documented, with no written procedures or records for complaint handling, corrective actions, or service assessment. Overseas service infrastructure is absent. Financial credibility cannot be fully assessed from the available data, although a current ratio of 0 is explicitly reported.

Supplier typeThe supplier is positioned as a manufacturer and technology provider covering electronic measuring instruments, intelligent instruments, industrial automation systems, software, vehicle-mounted devices, integrated-circuit design, and general equipment manufacturing. Its registered business scope indicates both product sales and manufacturing/technology activities.

CertificationsCE and RoHS certification capabilities are explicitly reported, supporting compliance for relevant products. However, the supplier also states that it has no factory environmental impact assessment report; this does not negate the reported certifications but limits the broader environmental compliance evidence.

After-Sales capabilityThe supplier reports no written procedures or records for effective service-capability assessment, corrective and preventive actions, or customer-complaint handling. It also has no overseas warehouses, showrooms, agents, or branches, indicating limited documented and overseas after-sales infrastructure.

Financial creditThe supplier reports a current ratio of 0, which is an explicitly adverse liquidity indicator. Although an annual production-output range is provided, no additional financial evidence is available to offset or contextualize this concern.

Production capacityThe supplier operates one production line, has 6–10 quality-control staff, and reports annual outputs of 1,448 ultrasonic liquid level sensors, 952 remote vehicle-mounted positioning terminals, and 805 data collectors. Peak-season lead time is one month and off-season lead time is within 15 workdays, while finished products are checked by packing staff, suggesting basic production capacity but limited evidence of comprehensive final inspection controls.

Customization capabilityThe supplier explicitly offers customization from designs and samples, full, minor, and flexible customization, and also provides ODM services. These repeated capabilities indicate broad design-to-product adaptation capacity.
