AI-Powered supplier vetting

SummaryChangda Electric is a manufacturing-oriented supplier established in 2011, operating a stated 26,000-square-meter standardized facility and five production lines. Its capabilities cover R&D, manufacturing, sales, and after-sales service, with customization, ODM, and OEM services available. The supplier reports State Grid certification, CE product compliance, and ISO9001, ISO45001, ISO14001, and ISO50001 management certifications. It has six experienced export-trade staff, with exports representing 71%–90% of total sales, and accepts multiple quotation and payment terms. Service procedures and complaint-handling mechanisms are documented and followed, although supplier-service assessment procedures lack records and no overseas service countries are reported. Financial credibility and customer cases cannot be adequately assessed from the provided information.

Supplier typeThe supplier presents itself as a full-lifecycle manufacturer covering R&D, precision manufacturing, sales, and after-sales service. Its stated business scope includes equipment and components, charging stations, and intelligent power transmission, distribution, and control equipment, indicating an industrial equipment and electrical-systems supplier rather than a purely trading company.

CertificationsThe supplier states that it is fully certified by the State Grid and has in-house testing and commissioning capabilities. It also reports CE product compliance and ISO9001:2015, ISO45001:2018, ISO14001, and ISO50001 certifications, providing explicit evidence of multiple product and management-system certifications.

After-Sales capabilityThe supplier states that after-sales service is part of its full product lifecycle and reports clear, followed procedures for corrective and preventive actions and customer complaints. However, the service-capability assessment procedure has written procedures but no records, and no overseas service countries are reported, so the evidence supports structured service handling but not broad international coverage.

R&D capabilityThe supplier reports R&D as part of its operations, launched new products during the past year, provides ODM services, and has an available SDK. It also reports one national science and technology progress award, giving explicit evidence of active product development and technical capability.

Production capacityThe supplier operates a stated 26,000-square-meter standardized facility with five production lines and listed equipment including punching, laser cutting, press-brake, and shearing machines. Finished-product inspection follows written instructions uniformly, but the factory does not conduct continuous quantity reconciliation for every batch or mass production, indicating a documented production base with a stated process-control gap.

Customization capabilityThe supplier explicitly offers customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, supporting broad design and product-adaptation capability.
