AI-Powered supplier vetting

SummaryYueqing Quansheng Electric Co., Ltd. is identified as a China-based manufacturer/factory producing circuit-protection and control products, including MCCBs, ACBs, VCBs, fireman switches, magnetic starters, and contactors. The supplier reports ISO 9001-based operations and additional product certifications such as CB, CE, and Semko. Stated annual capacity is 30,000 ACBs, 30,000 VCBs, and 200,000 MCCBs, supported by five production lines and 6–10 quality-control staff. The supplier has exported since 2013, with 90% of total sales reportedly from exports. Evidence supports manufacturing capability, export experience, quality-system certification, and product-focused R&D activity. However, the provided information does not establish after-sales service performance, financial credibility, customization capability, or named customer cases. The supplier’s company classification is somewhat inconsistent across records, which identify both a manufacturer/factory and a trading-company nature.

Supplier typeThe supplier is explicitly listed as a Manufacturer/Factory, with a stated focus on researching, producing, and manufacturing circuit breakers. However, another record classifies the company nature as a trading company, creating a classification inconsistency that should be verified.

CertificationsThe supplier reports ISO 9001 certification or an ISO 9001-based operating system, and also cites product certifications including CB, CE, and Semko. ISO 9001 is explicitly documented, while the other certifications are mentioned in the company description without certificate details.

R&D capabilityThe supplier states that it continuously researches and develops new products, has an operation system covering technical R&D, and is supported by innovative ideas and skilled professors. Its stated product focus is circuit protection, industrial control, and power management, but no R&D investment, patent, laboratory, or product-development metrics are provided.

Production capacityThe supplier reports five production lines and annual output of 30,000 ACBs, 30,000 VCBs, and 200,000 MCCBs, with 6–10 quality-control staff. It also identifies a factory location and manufacturing entity, providing explicit evidence of established production capability.
