AI-Powered supplier vetting

SummaryQingdao Gemsun Steel Structure Co., Ltd. is a private Chinese manufacturer/factory based in Jimo, Qingdao, Shandong, supplying steel structures, warehouses, buildings, workshops, mobile houses, and related prefabricated products. It reports annual steel-structure productivity of 5,000 tons and derives 90% of total sales from exports, with exporting activity beginning in 2015. The supplier provides OEM and ODM services and supports full customization, but reports no available SDK and no new products during the past year. ISO 9001:2015 certification and recent regular fire drills are stated. Service-management documentation is weak: supplier assessment and corrective/preventive-action procedures lack written records, and complaint handling has a procedure but no written records. No overseas warehouse, showroom, agent, branch, or overseas service coverage is reported. Financial data is represented only by years rather than substantive indicators and therefore cannot establish financial credibility.
