AI-Powered supplier vetting

SummarySOV Hydraulic Technology (Shanghai) Co., Ltd. is identified as a China-based trading company established in 2012, with 12 employees and operations associated with Shanghai. Its stated product range covers hydraulic cylinders, jacks, torque tools, pumps, synchronous lifting systems, bolt tensioners, pipe benders, and related equipment.

The company describes applications in steel, cement, chemical, refinery, bridge, railway, and other industrial projects, including synchronous hydraulic systems used in China high-speed railway construction. Evidence is insufficient to verify after-sales capability, financial credibility, customization capability, or a broad independently documented customer base.

Supplier typeThe supplier is explicitly classified as a trading company or limited trading entity, headquartered in Shanghai, China, with a stated factory location in Taizhou, Jiangsu. This indicates a trading-led business structure with identified production-related facilities, but the materials do not establish that it is primarily a manufacturer.
