AI-Powered supplier vetting

SummaryKoyosonic Power Co., Ltd. is identified as a Chinese manufacturer/factory in Guangdong with stated quality, engineering, customization, and export capabilities. It holds IFS, ISO 14001, ISO 9001, and SEDEX certifications, reports 21–30 quality-control staff, and states 100% finished-product inspection and raw-material traceability. It offers customization from samples and designs and provides ODM services, but has no SDK, no 3D software design service, and no new products reported in the past year. After-sales and service governance appear weak because no written procedures or records were reported for supplier service assessment, corrective actions, or complaint handling. The supplier has no overseas warehouse, showroom, agent, branch, or offline trade-show participation. Financial credibility cannot be confirmed from the provided year labels alone. OEM service for recognized brands is explicitly stated, but specific customer names or verifiable cases are not provided.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory, with its registered address in Guangzhou, Guangdong, China. Its stated business scope covers electronic-component retail, internet sales, domestic trade agency, photovoltaic equipment and components, surveillance systems, firefighting equipment, metal products, and installation services.

CertificationsThe supplier reports holding IFS, ISO 14001, ISO 9001, and SEDEX certifications. ISO 9001 indicates stated quality-management certification, while ISO 14001 and the other listed certifications broaden the reported management-system coverage.

After-Sales capabilityThe supplier reports no written procedures or records for customer-complaint handling, corrective and preventive actions, or service-capability assessment. It also has no overseas warehouse, showroom, agent, branch, or offline trade-show participation, although it accepts multiple quotation and payment terms and reports a one-month average lead time in both peak and off-season.

Production capacityThe supplier reports 100% finished-product inspection, raw-material traceability labels, and 21–30 quality-control staff. It also states an annual production output range, but the production figure cannot be reproduced because monetary data is excluded; physical capacity, equipment, and factory scale are not provided.

Customization capabilityThe supplier explicitly offers customization from samples and from customer designs, and also reports ODM service availability. However, it does not provide 3D software design services, so customization is supported but the available design-tool capability is limited.
