AI-Powered supplier vetting

SummaryNingbo Ketai Magnetic Material Co., Ltd. is a combined supplier whose primary product is magnets and whose stated business scope includes magnetic materials, plastics, rubber products, hardware, and electronic components. It offers customization and ODM services, maintains inventory capability, and reports quality assurance with raw-material traceability. However, it reported no new products during the past year, no SDK, no OEM service for popular brands, and no overseas agents, branches, warehouses, showrooms, or offline trade-show participation. Manufacturing capacity has a significant documentation weakness because there is no valid contract with the factory’s related subcontractors. Corrective-action and complaint-handling procedures are undocumented, while supplier assessment procedures and an approved-supplier list are also absent. An ISO 9001:2015 certificate is reported, but the provided audit result is 0 and no customer cases are supplied.

Supplier typeThe supplier is identified as a combined company, with a business scope covering magnetic material production and sales plus plastic, rubber, hardware, and electronic-component activities. Its primary offered product is magnets, and it is not identified as an offshore company.

CertificationsThe supplier reports an ISO 9001:2015 certificate, indicating a stated quality-management certification. However, the provided audit evaluation result is 0, so the available evidence does not establish an unqualified certification or audit strength.

After-Sales capabilityThe supplier has inventory capability and offers several quotation terms, but it has no overseas agent or branch, overseas warehouse, or overseas showroom. It also lacks written procedures or records for effectively handling customer complaints and corrective and preventive actions, which is an explicit service-process deficiency.

R&D capabilityThe supplier provides ODM services and lists multiple customization routes, but it reported no new products during the past year and has no available SDK. The explicit lack of recent new-product development is a deficiency for innovation capability.

Production capacityThe supplier states that it manufactures magnetic materials, plastics, and rubber products and has inventory capability, with peak- and off-season lead times both stated as one month. However, there is no valid contract between the factory and related subcontractors, and the audit evaluation result is 0; these are explicit concerns despite the stated manufacturing scope.

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