AI-Powered supplier vetting
SummaryZhejiang Tainihan Electrical Technology Co., Ltd. is a China-based factory established in 2015, focused on electronic and electromechanical energy meters. It operates two production lines in a 2,000 m² facility and reports annual output of 300,000 Kwh Meters, with stated one-month lead times in both peak and off-peak seasons. The company offers multiple single-phase, three-phase, DIN-rail, smart, and ANSI meter models, and states that its products have CE certification. Its development, design, production, and marketing capabilities are described, but the available evidence does not establish formal supplier-management certification, after-sales service arrangements, customization capability, or identifiable customer cases. The supplier has 17 employees, fewer than five quality-control staff, and two R&D engineers, indicating a relatively small operating structure.
Supplier typeThe supplier is identified as a limited company and a factory in China, with operations in Yueqing, Zhejiang. Its stated business integrates development, design, production, and marketing, and its commercial activities cover instruments, meters, electrical, and electronics.
CertificationsThe company states that its products have attained CE certification. However, supplier-management-system certification is explicitly recorded as NIL, so the evidence supports product certification but not certified supplier-management systems.
R&D capabilityThe company states that it integrates development and design, continually improves existing products, and develops new product lines. It reports two R&D engineers and a range including multi-functional, multi-rate, network, power-line-carrier, and multi-user energy meters, supporting some product-development capability.
Production capacityThe supplier operates two production lines in a 2,000 m² plant and reports output of 300,000 Kwh Meters, with one-month order fulfillment times in both peak and off-peak seasons. However, its workforce is small at 17 employees and quality-control staffing is below five, so the evidence supports operating production capability but indicates limited organizational scale.
