AI-Powered supplier vetting

SummaryHangzhou Longwin Industry Limited is a China-based limited company described as both a trading company and manufacturer/factory. It reports valid import/export licensing, six years of export experience, and exports accounting for 90% of total sales. Its stated capabilities include electric-vehicle production, OEM for popular brands, ODM, customization from samples and designs, and cooperation with overseas manufacturers and universities. However, several operational support capabilities are absent or limited: it has no overseas warehouse, showroom, agents or branches, or offline trade-show participation; it does not provide 3D design services or SDKs; and it reported no new products in the past year. Financial information is represented only by years, without sufficient evidence for a credibility assessment. Customer-specific cases and certifications are not provided.

Supplier typeThe supplier is identified as a limited company in Zhejiang, China, with its business type described as both Trading Company and Manufacturer/Factory; another slice identifies the company nature as a factory. This supports classification as a manufacturer with trading capability, but the reported employee count is 10 and no broader group affiliation is stated.

CertificationsThe supplier is explicitly reported to hold a valid import and export license. No product, quality, safety, or management-system certifications are provided, so the assessment is limited to trade licensing.

R&D capabilityThe supplier reports technical cooperation with renowned overseas manufacturers, equipment introduction, patent technologies, university cooperation, and research bases. Nevertheless, it reports no available SDK and no new products during the past year, so innovation evidence is positive but mixed.

Production capacityThe supplier states that production capability has reached an international advanced level and reports annual electric-vehicle productivity of 300,000 pieces, inventory capability, ODM availability, and lead times within 15 workdays in both seasons. The storage-battery and solar-panel productivity fields contain no quantities, so capacity is not established for those products.

Customization capabilityThe supplier explicitly provides customization from samples and from designs, and also offers ODM services. It does not provide 3D software design services, which limits the documented design-support scope but does not negate the stated customization capability.
