AI-Powered supplier vetting

SummaryThe supplier manufactures electronic components, including inductors, magnetic cores, skeletons, transformers, rectifiers, capacitors, and related materials. It reports substantial annual production capacities and holds ISO9001:2015 and ISO14001:2015 certifications. Customization and ODM services are available, but the supplier reported no new products in the past year and no SDK availability. Service-management controls are weakly documented: procedures and records for service assessment, corrective actions, and complaint handling are absent. Overseas service infrastructure is limited, with no overseas warehouse, showroom, agent, branch, or offline trade-show participation. Financial credibility cannot be conclusively assessed because the supplied financial figures are inconsistent and are not presented with clear units or definitions. No customer cases or famous-brand OEM experience were provided.

Supplier typeThe supplier is a manufacturer of electronic components, with stated business activities covering inductors, transformers, rectifiers, capacitors, electronic materials, and plastic products. Its company description also identifies production of inductors, magnetic cores, and skeletons, indicating a component manufacturing profile rather than a service-only or trading-only role.

CertificationsThe supplier holds ISO9001:2015 and ISO14001:2015 certificates according to its supplier-management information. A separate slice lists ISO9001:2015 as its sustainable-development management certification and confirms an environmental impact assessment report, although it also reports no regular fire drills in the past year.

After-Sales capabilityThe supplier offers stated quotation and payment options and reports peak- and off-season lead times within 15 working days, with access to Shanghai and Ningbo ports. However, it has no written procedures or records for service assessment, corrective and preventive actions, or complaint handling, and it has no overseas warehouse, showroom, agent, branch, or offline trade-show experience.

Production capacityThe supplier reports annual capacities of 850 million E-type inductors, 500 million H inductors, 100 million magnetic cores, and 100 million skeletons. Its business scope covers several related electronic-component categories, and it reports lead times within 15 working days in both peak and off-season periods, supporting a positive assessment of manufacturing capacity.

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