AI-Powered supplier vetting

SummarySUZHOU SHUNCHI HARDWARE CO., LTD. is identified as a China-based trading company established in 2018, with 10 employees and a 125.0 m² manufacturing plant. Its offerings focus on garage doors, industrial doors, hardware systems, high-speed doors, and loading dock equipment. The supplier claims continuous product innovation, technical support, quality focus, and on-time delivery. Reported operational data includes four production lines, 6–10 quality-control staff, substantial component output, and an export-sales share of 71%–90%; however, some records identify the business as CHI Hardware, creating a naming inconsistency. No certification information or detailed after-sales processes are provided. One buyer, RIVER CITY DOORS LTD, is listed, and imports from the US and shipments from Pusan are recorded.

Supplier typeThe supplier is explicitly classified as a Trading Company and Limited Company, based in Suzhou, Jiangsu, China. Its stated product range covers garage doors, industrial doors, hardware systems, high-speed doors, and loading dock equipment, while the listed manufacturing plant and production data indicate some operational production capability as well.

R&D capabilityThe company explicitly claims continuous product innovation and states that it designs newer and more precise products to meet customer requirements. This is direct evidence of an innovation focus, although no patents, development team details, or independently verified innovation results are supplied.

Production capacityThe supplier reports a 125.0 m² manufacturing plant, four production lines, 6–10 quality-control staff, and annual outputs of 2,000,000 roller shutter accessories and 10,000,000 garage door components. These figures provide explicit evidence of production activity and capacity, despite the supplier also being classified as a trading company.

Client casesRIVER CITY DOORS LTD is listed as a buyer associated with the supplier, and the records indicate imports to the US. This is one identifiable buyer reference, but the information does not provide order details, product scope, duration of cooperation, performance evidence, or multiple verified customer cases.
