AI-Powered supplier vetting

SummaryDadi Wanda Electronic Components Factory, established in 2010 in Beilun, Ningbo, specializes in developing, researching, and producing connectors. It reports 80 employees, quality assurance, raw-material traceability, 100% finished-product inspection, and broad customization services. The supplier holds BSCI and ISO 9000 certifications and reports export activity to multiple regions, but began exporting only one year ago. Its innovation profile is limited by one R&D engineer, no new products launched in the previous year, and no available SDK. Service infrastructure is also limited: no overseas showroom, agents, branches, or offline trade-show participation are reported. Financial records are identified by year, but their contents are not provided, so financial credibility cannot be assessed. Customer references or specific customer cases are not supplied.

Supplier typeThe supplier is identified as an electronic components factory established in 2010 that specializes in the development, research, and production of connectors. Its factory is located in Beilun District, Ningbo, with 80 employees and access to Ningbo and Shenzhen ports.

CertificationsThe supplier reports holding BSCI and ISO 9000 supplier-management-system certifications. These are explicit certifications stated in the company information, although no certificate scope, issue date, or validity details are provided.

R&D capabilityThe supplier states that it develops and researches connectors, but reports only one R&D engineer, no new products launched in the previous year, and no available SDK. The combination supports an existing development function but does not demonstrate strong current innovation output.

Production capacityThe supplier reports 80 employees, advanced manufacturing and testing equipment, 6–10 quality-control staff, raw-material traceability, and 100% finished-product inspection.
