AI-Powered supplier vetting

SummaryQingdao KXD Steel Structure Co., Ltd. is identified as a Chinese trading company and limited company operating in Shandong, with steel structures and prefabricated buildings as its stated business focus. The available information indicates more than 10 production lines, stated steel-structure capacity of 50,000 tons, approximately one-month lead times in both peak and off-peak periods, broad export-market coverage, and self-operated import/export rights. However, the records contain significant inconsistencies: one profile states 15 employees and a 276 m² plant, while another describes a company established in 1996 with 1,000 employees and multiple engineering personnel. ISO 9001:2000 certification and a first-class engineering contracting qualification are reported, but independent verification is unavailable. Evidence of after-sales service, innovation, customization, and customer cases is limited. Financial credibility cannot be assessed because the available registration and transaction information is...

Supplier typeThe supplier is explicitly classified as a Trading Company and Limited Company, while its stated business covers steel structures, prefabricated buildings, design, manufacturing, marketing, and construction. This indicates a trading-led supplier with claimed manufacturing and project-delivery activities, but the company-size descriptions are inconsistent across records.

CertificationsThe supplier states that it holds ISO 9001:2000 quality-system certification and a first-class professional steel-structure engineering contracting qualification. These are explicit positive certification claims, although the records do not provide certificate numbers, validity dates, or verification evidence.

Production capacityThe supplier reports more than 10 production lines, 50,000 tons of annual steel-structure output, one-month lead times in both peak and off-peak seasons, and a manufacturing-plant area of 276.0 m². These figures support stated production capability, but they conflict with the separate profile identifying the entity as a trading company with 15 employees and with another description claiming 1,000 employees.

Client casesThe supplier reports exports to South America, Africa, Southeast Asia and the Middle East, Europe, Australia, and North America, with exports representing 71%–90% of total sales. Three trade records list H E JACKSON ENGINEERING LTD as a buyer for MS pipes, M16 bolts, and M16 hex nuts, but each record shows only one transaction and no detailed project outcome or reference case.
