AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with manufacturing and export activities spanning tires, automotive parts, rubber and plastic products, hardware, security equipment, sanitary ware, and related goods. It reports broad customization services, recent new-product activity, ODM capability, OEM service for known brands, an available SDK, and one national science and technology progress award.

Supplier typeThe supplier is classified as a combined company and its registered business scope covers manufacturing and sales of tires, automotive parts, rubber and plastic products, hardware, security equipment, sanitary ware, and other goods, together with import and export activities. This indicates a diversified manufacturer-trader profile rather than a narrowly specialized supplier.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, has an available SDK, and holds one national science and technology progress award. These points explicitly support active product development and technical capability.

Production capacityProduction capability is supported by three production lines, listed rubber-processing equipment including mixers, mills, extruders, forming and vulcanization machines, and manufacturing scopes covering tires, automotive parts, rubber, plastic, and hardware products. Quality control includes two inspectors and standardized finished-product inspection instructions, but the factory does not continuously reconcile quantities for each batch or production lot.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service and recent new-product activity, providing direct evidence of broad customization support.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of at least one category of customer engagement. No brand names, project details, product examples, or performance records are provided, limiting the depth of case verification.
