AI-Powered supplier vetting
SummaryNingbo Aoshun Electrical Co., Ltd is identified as a China-based trading company in Zhejiang, offering a broad range of ventilation and electrical products. It reports five production lines and an annual exhaust-fan output of 10,000,000 pieces, with exports to multiple regions. The supplier demonstrates product development, ODM, and OEM capabilities, and has participated in an international trade show. However, it reports no available SDK, overseas showroom, overseas agents, or branches. Service-management documentation is weak: no written procedures, approved-supplier list, corrective/preventive-action records, or complaint-handling records were reported. Financial information is represented only by years rather than evaluable financial results, while sustainability and environmental compliance status is unknown. The available evidence supports production, customization, and innovation strengths, but does not substantiate certifications or customer cases.
Supplier typeThe supplier is consistently identified as a trading company and limited company, based in Ningbo, Zhejiang, China, with no stated affiliation to a larger company group. Its stated business activities cover electrical, mechanical-electrical, household-appliance, building-fittings, and related product sales.
After-Sales capabilityThe supplier has participated in an offline trade show, but reports no overseas showroom, agents, or branches and zero countries served overseas. It also reports no written service-assessment procedures, approved-supplier list, corrective/preventive-action records, or documented complaint-handling procedures, indicating limited documented after-sales infrastructure.
R&D capabilityThe supplier reports new products during the past year and provides ODM services, demonstrating product-development and design-manufacturing capability. However, it explicitly reports no available SDK, so its innovation support does not extend to SDK availability.
Production capacityThe supplier reports five production lines and annual exhaust-fan output of 10,000,000 pieces, with a product range spanning wall-mounted, ceiling-mounted, inline, centrifugal, industrial, air-curtain, and related ventilation products. It also reports exports to South America, the Middle East, Southeast Asia, Oceania, and Western Europe, supporting substantial production and market coverage.
Customization capabilityThe supplier explicitly reports ODM service availability and OEM service for well-known brands. These statements directly support its ability to provide customized or customer-branded manufacturing services.
