AI-Powered supplier vetting

SummaryShuntong Electric Co., Ltd. is a manufacturing enterprise established in 2009 in Zhejiang, China, specializing in high- and low-voltage equipment. It reports OEM service for recognized brands, broad export coverage, and design customization capabilities. Quality-related strengths include written procedures, retained records, ISO9001, ISO14001, OHSAS18001, CB, SEMKO, CE, and CCC certifications. Service processes include documented complaint handling and corrective/preventive actions. Production is supported by one production line, 11–20 quality control staff, and stated lead times of within 15 working days off-season and one month during peak season. Innovation resources appear limited: one R&D engineer is identified, and no SDK is available. Quality test equipment is reported as zero, and ongoing batch quantity reconciliation is not performed. Financial information is limited to year labels without performance values, so financial credibility cannot be determined.

Supplier typeThe supplier is explicitly described as a professional manufacturing enterprise integrating development, production, sales, and service, specializing in high- and low-voltage equipment. It operates one production line and provides export-oriented manufacturing services, including exports through agents.

CertificationsThe company states that it holds ISO9001, ISO14001, OHSAS18001, CB, SEMKO, and CE certifications, and CCC is also listed as a sustainable development and product certification capability. These are explicit certification claims supporting this field.

After-Sales capabilityThe R&D engineer’s responsibilities include technical support for production and after-sales service. The supplier also reports written procedures and retained records for service assessment, corrective and preventive actions, and effective customer complaint handling.

Production capacityThe supplier operates one production line and reports annual output in a stated range, with 11–20 quality control staff and standardized finished-product inspection instructions. However, quality test equipment is reported as zero and ongoing quantity reconciliation for each batch or mass production is not performed, indicating material production-control limitations.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. This indicates broad stated support for customer-specific product requirements.
