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.
