AI-Powered supplier vetting

SummaryZhejiang Kepai Electrical Appliance Co., Ltd. is a China-based limited company established in 2015, offering voltage regulators, transformers, variacs, and power inverters. The supplier states that it holds ISO 9001:2000 and CE certifications and maintains an after-sales service system responsive to customer feedback. It describes advanced production equipment, including CNC machinery and a professional spraying line, and claims that its products are exported internationally and used in industrial, commercial, and household electrical applications. However, the provided records contain conflicting employee figures: one administrative record states 9 employees, while the company description claims over 120 employees.

Supplier typeThe supplier is identified as Zhejiang Kepai Electrical Appliance Co., Ltd., a combined business entity and limited company based in Zhejiang, China. Its stated product scope includes voltage regulators, transformers, variacs, and power inverters.

CertificationsThe supplier explicitly states that its products have obtained ISO 9001:2000 quality management system certification and European Community CE certification. These claims provide direct evidence of certification holding, although no certificate numbers or validity dates are supplied.

These statements directly support an after-sales capability, although service response metrics are not provided.

Production capacityThe supplier reports advanced production facilities, including CNC machining, shearing, folding, punching equipment, and a professional spraying line. Its stated manufacturing workforce is inconsistent with the administrative record, which lists 9 employees versus the company description's claim of over 120, so production scale is not fully verifiable.
