AI-Powered supplier vetting

SummaryQINGDAO I-FLOW CO., LTD. is a China-based limited trading company established in 2010, with a sales office in Qingdao and a stated factory address in Shandong. Its business focuses on industrial valves, pipe fittings, flanges, and related components. The supplier reports ISO 9001:2015 certification, more than 10 production lines, over 50 quality-control staff, and an annual production output range stated in the source. Export sales account for 90%, and exporting began in 2020. The supplier describes a broad product range exceeding 50 types, available in over 400 sizes and 20 materials, indicating product breadth and potential customization scope. It also cites overseas markets, industrial and commercial users, and associated-company certifications including CE, WRAS, DNV, GL, LR, and ABS. However, the available information contains inconsistencies: the stated employee count is 20 while quality-control staff are stated as 50, and the manufacturing plant area is only 227.96 m² despite the reported...

CertificationsThe supplier explicitly reports an ISO 9001:2015 management-system certificate. It also states that the supplier and associated company have obtained CE, WRAS, DNV, GL, LR, and ABS certificates, although the evidence does not clearly distinguish which certificates are held directly by the target supplier.

Production capacityThe supplier states that it operates more than 10 production lines, employs 50 quality-control staff, and has annual production output within the range reported in the source. It also identifies itself as a factory and provides a manufacturing-plant area of 227.96 m², but the employee and facility figures are inconsistent with one another and should be verified before relying on the stated production scale.

Customization capabilityThe stated availability of more than 50 product types in over 400 sizes and 20 materials indicates substantial configuration breadth for valves and related industrial components. The evidence does not explicitly confirm bespoke design, engineering modification, or made-to-order production, so customization beyond standard variations remains unverified.

Client casesThe supplier cites product use in Shangri-La Hotel, Kerry Center, Milan Expo, a FIAT workshop, IKEA, and MSC vessels, and mentions customers or markets across multiple countries. These are explicit referenced applications, although the evidence does not provide project dates, order scope, contract details, or independently verifiable customer testimonials.
