AI-Powered supplier vetting

SummaryShenzhen Limai Electronics Co., Ltd. is identified as a Chinese manufacturer/factory founded in Shenzhen in 2012, supplying access control, smart lock, barrier, elevator control, visitor management, and facial recognition products. It reports recent new-product activity, four R&D engineers, ODM services, and broad customization options. However, the supplier has no valid import/export license, no overseas warehouses, showrooms, agents, or offline trade-show participation, and reports no formal procedures or records for service assessment, corrective actions, or complaint handling. GMP certification is stated, but customer-case evidence is limited because no Fortune 500 cooperation is reported.
