AI-Powered supplier vetting

SummaryShenzhen Kexint Technology Co., Ltd. is a China-based limited company established in 2015 with 53 employees and affiliated companies. Its product scope includes ONU, fiber cable, fiber optic patch panels, and fiber optic distribution boxes. The supplier demonstrates strong quality-control procedures, including 100% finished-product inspection, six quality inspectors, and documented inspection instructions. It offers broad customization and has an available SDK, but reports no new products in the past year, no ODM service, and no OEM service for popular brands. Service procedures, complaint handling, and corrective/preventive actions are documented and followed. Inventory capability and stated lead times within 15 working days are positive, while the lack of a valid manufacturing-capacity contract with related subcontractors, overseas warehouse, and overseas showroom represent operational limitations. Financial records are indicated for multiple years, but no financial figures or performance results are...

Supplier typeThe supplier is identified as a combined business entity and a limited company operating in China, with 53 employees, affiliated companies, and product offerings in optical-networking equipment and fiber products. This establishes a defined legal and operating profile, although its general trade-volume range is unknown.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaints, and it has inventory capability. However, it lacks overseas warehouse and showroom capabilities; the evidence supports domestic or general service-process capability but does not establish comprehensive overseas after-sales coverage.

Production capacityThe supplier offers fiber cable and related optical-networking products, has 100% finished-product inspection, six quality inspectors, documented inspection instructions, inventory capability, and stated lead times within 15 working days in both peak and off-season. Production-capacity risk remains because there is no valid manufacturing-capacity contract with the factory and related subcontractors.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. These capabilities are consistently reported across quality/design and R&D information, although no specific customized project examples are provided.
