AI-Powered supplier vetting

SummaryZhejiang Haoke Electric Co., Ltd. is a private manufacturer focused on heavy-duty connectors and sockets for industrial, manufacturing, electrical, and electronics applications. It reports broad customization and ODM capabilities, new product development during the past year, multiple product series, and thousands of combinations. The supplier holds or reports CE, ISO9001:2015, ISO45001:2018, ISO14001, and UL-related certifications or reports. Service processes include documented inspection, supplier management, corrective action, and complaint-handling procedures. It offers in-stock capacity, maintains stated lead times of within 15 workdays in both peak and off-season periods, and exports 31%–40% of total sales. However, it has no effective manufacturing contract with related subcontractors, no overseas warehouse or showroom, and no SDK. The supplied information does not provide specific customer case details or enough evidence to assess financial credibility.

Supplier typeThe supplier is identified as a private enterprise engaged in the R&D, design, manufacturing, sales, and after-sales service of heavy-duty connectors and sockets. Its stated markets include industrial equipment, manufacturing and processing machinery, and electrical and electronics, indicating a specialized manufacturer rather than a general trading supplier.

CertificationsThe supplier reports CE and other product-compliance certifications, ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, as well as UL and other raw-material quality reports. These stated certifications and reports provide explicit evidence of formal quality, occupational safety, environmental, and product-compliance systems.

After-Sales capabilityAfter-sales service is expressly included in the company’s business scope, and the supplier reports written and followed procedures for service assessment, corrective and preventive actions, and effective customer complaint handling. This supports a documented after-sales management capability.

R&D capabilityThe supplier reports having launched new products during the past year, provides ODM services, and has developed multiple HA, HE, HEE, HD, HDD, HSB, HK, and HQ product series with thousands of combinations. However, it reports no available SDK, which limits evidence of software or integration-development capability but does not negate its documented product R&D capability.

Production capacityThe supplier identifies manufacturing equipment including automatic laser marking and shot blasting machines, follows uniform finished-product inspection instructions, has in-stock capacity, and states average lead times within 15 workdays in both peak and off-season periods. A deficiency is also stated: there is no valid manufacturing-capacity contract with affiliated subcontractors, which may reduce documented subcontracting assurance.

Customization capabilityBoth R&D and design-capability records list customization from samples, customization from designs, full customization, minor customization, and flexible customization. The supplier also reports ODM service availability, providing explicit evidence of broad customization support.
