AI-Powered supplier vetting

SummaryYueqing Long Road Electric Co., Ltd. is a China-based limited trading company established in 2014 according to its business profile, while its company description states it was founded in 2010. It supplies low-voltage electrical products, including MCBs, RCCBs, SPDs, MCCBs, contactors, relays, isolators, and photovoltaic combiner boxes. The supplier reports ISO9001:2015 certification, multiple product certifications, eight production lines, MCB output of 20 million pieces, and one-month lead times in both peak and off-peak seasons. It claims exports to more than 80 countries and regions, although the detailed export-market information is limited to Africa, Southeast Asia, and the Middle East. Evidence supports broad product coverage, documented quality systems, and claimed innovation capabilities. However, after-sales resources, customization capability, financial credibility, and customer performance are insufficiently verified. The profile also contains inconsistencies regarding founding year, supplier...

CertificationsThe supplier explicitly reports an ISO9001:2015 management-system certificate. It also claims product certifications including CE, CB, IEC, SGS, Nemko, SAA, SASO, TUV, CCC, Golden Sun, and VDE, but the provided slices do not include certificate numbers, validity dates, or verification documents.

R&D capabilityThe supplier claims strong independent innovation capabilities, core technologies, multiple patents, and leading-level Internet of Things circuit breakers and photovoltaic and communications DC power-distribution products. These statements provide explicit positive evidence, although patent details and independent technical validation are not included.

Production capacityThe profile reports eight production lines, an MCB output of 20 million pieces, a 300.0 m² manufacturing plant, and one-month order fulfillment in both peak and off-peak seasons. These figures support established production capacity, although the relationship between the reported plant area, production lines, and the supplier's trading-company classification is not clarified.

Client casesThe supplier claims sales to countries and regions including the UK, Spain, Portugal, Singapore, Turkey, Russia, Korea, South Africa, and Nigeria, and separately claims coverage of more than 80 countries and regions. A detailed trade record identifies BTCPOWER CEBU INC as an associated buyer with one recorded transaction, providing some customer evidence but not enough to demonstrate a broad, verified customer portfolio.
