AI-Powered supplier vetting
SummaryWenzhou Yuanda Electrical Equipment Co., Ltd. is a China-based manufacturer established in 1993, with 280 employees, more than 10 production lines, 50 quality-control staff, and stated output capacities for voltage stabilizers, miniature circuit breakers, and AC contactors. The supplier reports ISO 9001:2015 certification and product certifications including UL, CE, and 3C, as well as design patent technology. Its stated processes include advanced design software, testing equipment, and controls from raw-material procurement through finished products. However, the available information does not verify contract manufacturing, inventory, overseas services, ODM/OEM, SDK, environmental, or fire-drill capabilities. No customer cases or financial-strength evidence is provided. The audit record identifies TUV Rheinland and a valid report period, but the audit result is recorded as “0” without an explained interpretation.
Supplier typeThe supplier is explicitly identified as a manufacturer and a limited company located in Zhejiang, China. It has operated since 1993, supporting classification as an established manufacturing supplier.
CertificationsThe supplier reports ISO 9001:2015 certification and product certifications including US UL, EC CE, and 3C; it also states that it has held an industrial production permit and received export-advanced-enterprise recognition for three consecutive years. A TUV Rheinland audit report is listed with dates from November 4, 2025 to November 3, 2026, although the recorded audit result of “0” is not explained.
After-Sales capabilityThe supplier states that its marketing center provides comprehensive pre-sale, in-sale, and after-sale service to customers worldwide. However, overseas warehouse, showroom, and overseas agent or branch capabilities are all marked unknown, so the depth and delivery model of after-sales support cannot be fully verified.
R&D capabilityThe supplier reports using PROE/CAD and other design software, integrating decades of low-voltage electrical manufacturing experience, and holding product design patent technology. ODM, SDK, private-mold, 3D-design, and new-product R&D capabilities are marked unknown, limiting confirmation of broader innovation services.
Production capacityThe supplier reports more than 10 production lines, 50 quality-control staff, and stated annual capacities of 1,000,000 voltage-stabilizer boxes, 5,000,000 miniature circuit-breaker boxes, and 2,000,000 AC-contactor bags. It also describes testing equipment and process controls from raw-material procurement through finished production, providing explicit evidence of substantial production and quality-control infrastructure.
