AI-Powered supplier vetting

SummaryL&R ELECTRIC GROUP CO., LTD. is identified as a China-based manufacturer established in 2015, with 77 employees, a 20,000 m² manufacturing plant, and more than 10 production lines. Its product scope includes electrical power and hardware components such as fuse links, clamps, surge arresters, and related accessories. The supplier reports OHSAS18001:2007 and other management-system certifications, 11–20 quality-control staff, and export sales representing 71%–90% of total sales. It states that it seeks worldwide sales-agent and maintenance partners, indicating an intended international service network, but actual after-sales coverage is not confirmed. Evidence of overseas trade exists through one recorded Kenyan buyer and three transactions, while broader customer references, customization capability, financial credibility, and innovation capacity remain insufficiently documented.

Supplier typeThe supplier is described as both a trade company and a manufacturer, while the formal entity record identifies L&R ELECTRIC GROUP CO., LTD. as a manufacturer and limited company in China. Its stated products and manufacturing-site information support a manufacturing role, despite the conflicting trade-company classification in the basic information.

CertificationsThe supplier reports holding an OHSAS18001:2007 certificate and additional unspecified certifications. This provides explicit evidence of at least one occupational health and safety management certification, although the other certifications are not identified.

Production capacityThe supplier reports a 20,000 m² manufacturing plant, more than 10 production lines, 77 employees, 11–20 quality-control staff, and one-month order fulfillment in both peak and off-peak seasons. These figures explicitly support substantial production infrastructure and stated delivery capacity, although actual capacity utilization and output verification are not provided.

Client casesThe supplier reports Africa as a primary export market and the trade records show one Kenyan buyer, SHOWAN LIMITED, associated with three recorded fuse-link transactions in January 2025. This demonstrates at least one identifiable overseas buyer case, but the evidence is limited and does not establish a broad, well-verified customer portfolio.
