AI-Powered supplier vetting

SummaryQingdao Chengzhi United Tech Power Engineering Co., Ltd. is a China-based trading company established in 2025, with two employees and no stated group affiliation. Its offerings cover steam turbines, generators, spare parts, maintenance, upgrades, and power-plant EPC services. The supplier reports annual productivity of 5,000 steam-turbine and spare-parts sets, one R&D engineer, flexible customization, and 90% export sales, but identifies its primary export markets as domestic. Quality-control resources and procedures are weakly documented: no quality-control staff are stated, testing equipment is listed as zero, and written complaint-handling and corrective-action procedures are absent. No certification, customer cases, or overseas service network is provided. Production outsourcing controls, raw-material traceability, and quality assurance remain unknown.

Supplier typeThe supplier is explicitly identified as a trading company and a limited company, established in China in 2025. Its stated scope includes turbine and generator products, spare parts, maintenance, upgrades, and EPC services, but the available profile does not establish that it owns manufacturing facilities.

After-Sales capabilityThe supplier offers maintenance, overhaul, upgrade, and repair-related services, with Qingdao Port identified as the nearest service location. However, it has no overseas agents or branches, no overseas warehouse or showroom, serves zero stated overseas countries, and has no written complaint-handling or corrective-action procedures.

R&D capabilityThe supplier reports one R&D engineer and flexible customization capabilities, but launched no new products in the past year. The evidence indicates some technical development capacity but does not demonstrate strong or sustained innovation.

Customization capabilityThe supplier explicitly offers flexible customization, including minor and full customization, for its product and service scope. This is direct evidence of customization capability, although no project examples or technical limitations are provided.
