AI-Powered supplier vetting

SummaryQingdao Universal International Trade Co., Ltd. is identified as a Chinese manufacturer/factory established in 2009, supplying permanent magnet generators, horizontal and vertical wind turbines, graphite, controllers, inverters, and transformers. The supplier reports ISO 9001 and ISO 14001 certification, four production lines, 50 quality-control staff, and R&D engineer experience of 11–20 years. It states that generator capacity ranges from 500W to 5MW and that speed and size can be customized. The company claims exports to more than 50 countries and lists broad global export markets. Evidence supports production, certification, customization, and international sales capabilities. However, the provided information does not sufficiently verify after-sales service processes, financial credibility, or specific customer cases. The supplier’s descriptions mention professional engineering, system-design, and sales teams, but do not provide concrete innovation outputs or documented customer references.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and describes itself as producing and exporting permanent magnet generators, wind turbines, transformers, inverters, controllers, and graphite. Its stated establishment in 2009 and factory location in Qingdao further support an operating manufacturing business.

CertificationsThe supplier explicitly reports holding ISO 9001 and ISO 14001 management-system certifications. The slices do not provide certificate numbers, issuing bodies, validity periods, or scope, but the stated certifications are direct positive evidence.

Production capacityThe supplier identifies itself as a manufacturer, reports four production lines and 50 quality-control staff, and offers multiple product categories. It states that permanent magnet generators can be produced from 500W to 5MW, with peak-season fulfillment of one month and off-peak lead time within 15 workdays, providing direct evidence of production capability.

Customization capabilityThe supplier explicitly states that permanent magnet generator speed and size can be customized according to customer requirements and that it provides customized generation-system solutions. Its system-design team also supports this claim, although the scope and limits of customization are not specified.
