AI-Powered supplier vetting
SummaryZhejiang Guozhen Electric Co., LTD. is a China-based manufacturer/factory producing distribution switch control equipment, wires and cables, and power transmission equipment. It reports ISO9001 and CCC certifications, national patents, OEM service for well-known brands, ODM capability, and broad customization options. Export sales account for 90% of total sales, with stated lead times within 15 working days in both peak and off-season periods. However, the supplier has no overseas warehouse, showroom, agent/branch, or offline trade-show participation, and reports no new products in the past year or available SDK. Service-management weaknesses include the absence of written procedures or records for service assessment, corrective/preventive actions, and complaint handling. Financial information is limited to years identified in the slices, without performance values, so financial credibility cannot be fully assessed.
Supplier typeThe supplier is identified as a manufacturer/factory and a limited company based in Zhejiang, China. Its stated business scope covers manufacturing and sales of distribution switch control equipment, wires and cables, and power transmission equipment, directly supporting classification as an industrial manufacturer.
CertificationsThe company description explicitly states that the supplier has successively passed ISO9001 quality management system certification and CCC certification, and holds a number of national patents. These are direct positive indicators of documented quality-system and product-related credentials.
After-Sales capabilityThe supplier claims to have a complete after-sales service system providing guidance and assistance, but the assessment record states there are no written procedures or followed records for service capability assessment, corrective/preventive actions, or effective complaint handling. The documented management evidence therefore shows a deficiency despite the company’s service claim.
Production capacityThe supplier is a manufacturer/factory with stated manufacturing scope for electrical distribution and power-transmission products. It reports finished-product checks by packing staff, export sales of 90%, access to Ningbo and Shanghai ports, and average lead times within 15 working days in both peak and off-season; these facts support operational production and export capability, although the inspection method is limited in detail.
Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization. It also offers ODM services, providing direct evidence of broad product customization and design-manufacturing support.
Client casesThe supplier states that it provides OEM services for well-known brands and has supplied more than 100 large, small, and medium-sized enterprises. These are explicit customer-related claims, but no customer names, project details, or independently verifiable case descriptions are provided.
