AI-Powered supplier vetting

SummaryZhilu Power is a Zhejiang-based high-tech enterprise focused on researching, manufacturing, and selling power transmission and distribution equipment and new-energy power products. It reports broad customization and ODM/OEM capabilities, including OEM service for popular brands, but no new product development in the past year and no available SDK. The supplier has a 1,320 m² manufacturing plant and a stated portfolio covering electrical, power facility, control, cable, instrument, and mechanical products. Quality and service governance evidence is weak: no certification of supplier management systems is reported, and no written procedures or records were provided for service assessment, corrective/preventive action, or complaint handling. Overseas service infrastructure and offline trade-show participation are absent. Financial-related records are labeled by year, but no substantive financial performance evidence is provided.

Supplier typeThe supplier is identified as a manufacturer and seller of power transmission and distribution equipment, new-energy power products, electrical accessories, control equipment, power facility equipment, cables, instruments, and related mechanical products. Its stated business scope supports classification as an electrical and power-equipment manufacturer rather than only a trading company.

After-Sales capabilityThe supplier provided no written procedures or records for assessing service capability, corrective and preventive actions, or effective customer-complaint handling. It also reports no overseas warehouse, showroom, agent or branch, and no offline trade-show participation, indicating limited documented and overseas service infrastructure.

Production capacityThe supplier reports a 1,320 m² manufacturing plant and manufacturing activities spanning electrical accessories, power facility equipment and materials, hardware, instruments, and mechanical products. The listed combined facility equipment and product scope support established production capability, although no capacity, output, or workforce data is provided.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM capability, providing direct evidence of broad customization support.
