AI-Powered supplier vetting

SummaryQingzhou Junhang Environmental Protection Technology Co., Ltd. is identified as a Chinese trading company established in 2025, while its profile describes manufacturer-oriented capabilities in ship design, dredging equipment, engineering-vessel construction, and related machinery. It reports ISO9001 certification, compliance with China Classification Society requirements, dedicated engineering, quality inspection, and after-sales personnel, and the ability to design machinery for specific customer requirements. The supplier states that it operates five production lines, employs more than 300 people, and reports annual output across several vessel and machinery categories. Its products are reportedly exported to numerous countries. However, the available information contains inconsistencies: the registered company type is “Trading Company,” total staff experience is listed as zero, and the reported manufacturing-plant area is only 126.0 m² despite the stated 300-acre company area. Customer references are...

CertificationsThe supplier explicitly states that it has obtained ISO9001 quality-system certification and that ship design, construction, quality inspection, and accessories are completed according to China Classification Society requirements. These statements provide direct evidence of documented quality certification and stated classification compliance.

After-Sales capabilityThe supplier reports 20 after-sales service technicians and identifies an after-sales department within its organizational structure. This is direct evidence of dedicated after-sales resources, although no response-time, geographic coverage, or service-performance details are provided.

R&D capabilityThe company reports 15 senior engineers specializing in shipbuilding and dredging research, a research and development center, cooperation with classification societies and research institutions, and the ability to develop special machinery. These details directly support an established technical and R&D capability.

Customization capabilityThe supplier explicitly states that it can design and produce special types of machinery according to customer requirements and describes a one-stop model covering ship design, R&D, innovation, manufacturing, and dredging-engineering construction. This directly supports customization capability for specialized vessels and machinery.
