AI-Powered supplier vetting

SummaryNingbo Ketai Magnetic Material Co., Ltd. is identified as a combined company offering magnets and related magnetic, plastic, rubber, hardware, and electronic-component activities. It provides multiple customization modes and ODM services, and reports quality assurance with raw-material traceability. However, it reported no new products during the past year, no available SDK, and no OEM service for popular brands. Manufacturing capacity is supported by inventory capability and one-month average lead times, but there is no valid manufacturing contract with affiliated subcontractors. Overseas support is limited: no overseas warehouse, showroom, agents, branches, or offline trade-show participation were reported. Service governance also has weaknesses, including no written supplier-assessment, corrective-action, or complaint-handling procedures and no approved supplier list. ISO9001:2015 certification is reported, while an audit by CTI is documented with a report period from March 31, 2026 to March 30, 2027;...

Supplier typeThe supplier is classified as a combined company, with magnets as its primary product. Its stated business scope also includes magnetic materials, plastic and rubber products, hardware, electronic components, and related import/export agency activities, indicating a manufacturing and trading-oriented supplier profile.

CertificationsThe supplier reports quality assurance and raw-material traceability, and holds an ISO9001:2015 certificate according to the sustainable-development information. A CTI audit report is also documented, although the stated audit evaluation result is 0 and no explanation of that result is provided.

After-Sales capabilityThe supplier reports no written procedures or records for handling customer complaints, and it has no overseas warehouse, showroom, agent, or branch. These facts indicate limited documented after-sales and overseas service infrastructure.

R&D capabilityThe supplier offers ODM services and can customize from samples, designs, or through full or minor customization. However, it reported no new products during the past year and no available SDK, so evidence of ongoing product innovation is limited.

Production capacityThe stated scope includes manufacturing of magnetic materials, plastic products, rubber products, and hardware, while inventory capability is available and average peak- and off-season lead times are each one month. Nevertheless, there is no valid contract between the factory and affiliated subcontractors, creating a documented manufacturing-governance deficiency.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, and minor customization, and also provides ODM services. These stated service options directly demonstrate broad customization capability.
