AI-Powered supplier vetting

SummaryYueqing Chuxi Electric Co., Ltd. is a China-based limited trading company established in 2016, with three employees and products including sensors, switching power supplies, float switches, and solid-state relays. It reports OEM service for well-known brands, ODM availability, and broad customization services. However, no supplier-management-system certification is reported, no new products were launched during the past year, and no SDK is available. Service-management procedures, complaint-handling procedures, corrective and preventive action records, and raw-material traceability are not documented or are unknown. The supplier has substantial export activity, but no valid import/export license is reported and exports may be conducted through agents. Financial evidence is limited to referenced years without disclosed financial figures. The available information supports customization and reported OEM/ODM capability, while production scale, after-sales controls, financial credibility, and customer-case...

CertificationsNo supplier-management-system certification is reported. An SGS audit is documented with a report period from September 24, 2024 to September 23, 2025, but the recorded audit result is 0 and no specific certification or favorable evaluation is provided.

After-Sales capabilityThe supplier lists 10 qualified service suppliers and provides some supplier names, but it has no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling. This explicitly indicates deficiencies in documented after-sales management controls.

R&D capabilityThe supplier reports one year of total R&D-engineer experience, no new products during the past year, and no available SDK. Although ODM service and multiple customization options are offered, the stated lack of recent product development and SDK support does not demonstrate strong independent innovation.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad stated customization services.
