AI-Powered supplier vetting
SummaryL&R ELECTRIC GROUP CO., LTD. is identified as a Chinese manufacturer established in 2015, with 77 employees and a 20,000 m² manufacturing plant. It reports more than 10 production lines, 11–20 quality-control staff, and experience across electrical and related product categories. The supplier holds an OHSAS18001:2007 certificate and reports three years of R&D engineer experience. Export activity is substantial, with Africa listed as a primary market, exports representing 71%–90% of sales, and stated one-month lead times in both peak and off-peak seasons. Evidence of after-sales capability, customization, and financial credibility is insufficient. Trade records show one transaction each for three 33kV fuse-link products with a buyer in Kenya, supporting limited evidence of customer transaction history.
Supplier typeThe supplier is described as a manufacturer and limited company, while another record classifies the company nature as a trading company. Its manufacturer designation, manufacturing plant, and production information indicate manufacturing capability, but the conflicting classification should be noted.
CertificationsThe supplier reports holding an OHSAS18001:2007 certificate and other certifications. The provided evidence confirms a management-system certification, although the unspecified additional certifications cannot be assessed.
Production capacityThe supplier reports a 20,000 m² manufacturing plant, more than 10 production lines, and one-month order fulfillment in both peak and off-peak seasons. Its product keywords cover multiple electrical hardware and protection products, while the reported 11–20 quality-control staff further supports operational capacity.
Client casesTrade records identify SHOWAN LIMITED as a buyer in Kenya and show one transaction each for three 33kV fuse-link products in January 2025. This provides evidence of a limited documented customer history, but the small number of recorded transactions does not establish a broad or extensive customer portfolio.
