AI-Powered supplier vetting
SummaryThe supplier operates in power transmission, distribution, monitoring, control, electrical equipment, instruments, software, and related technical services. It reports more than 22 years of core-team development and nationwide recognition, while export activity began one year ago and exports represent 51%–70% of sales. The supplier provides extensive customization and 3D software design services, but reports no new products in the past year and has only one R&D engineer. Quality-related certifications include ISO 9001:2015 and CE. Quality assurance is stated, although finished products are checked by packing staff, and no written corrective-action or complaint-handling procedures are reported. The supplier has no stated inventory, overseas warehouse, or overseas showroom capability. No Fortune 500 cooperation is reported, and the available financial figures are not sufficient for assessment.
