AI-Powered supplier vetting

SummaryThe supplier is a combined electrical and electronics company engaged in the production, sales, installation, research, and development of wires and cables. It reports OEM service for well-known brands, certifications including CCC, ISO 9001:2015, ISO 45001:2018, and ISO 14001, and a manufacturing plant of 9,891 m². Its stated product range includes power, electrical, photovoltaic, aluminum, and copper cables. Service procedures, complaint handling, and corrective/preventive action processes are documented and supported by records. The supplier has inventory capability, accepts several quotation and payment terms, and reports lead times within 15 working days in both peak and off-season periods. However, it has no available SDK, no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, and no explicit customer case references in the provided information. Financial data is limited to year labels and does not permit a substantive assessment.

Supplier typeThe supplier is identified as an electrical and electronics company and a combined company type. Its business scope covers production, sales, installation, research and development, promotion, and sales of wire and cable products, indicating a manufacturer with related technical and commercial functions.

CertificationsThe supplier reports CCC product certification and ISO 9001:2015, ISO 45001:2018, and ISO 14001 management-system certifications. The company description also lists a National Industrial Product Manufacturing License and additional provincial quality and integrity credentials, providing explicit evidence of certification coverage.

After-Sales capabilityThe supplier has in-stock service capacity, documented procedures and records for service assessment, corrective and preventive actions, and customer complaint handling. It lacks an overseas warehouse and overseas showroom, so the evidence supports structured service management but not comprehensive overseas service infrastructure.

R&D capabilityThe business scope explicitly includes research and development, promotion, and production of new cable product technology. However, the supplier states that no SDK is available, so the evidence demonstrates product-technology R&D activity but does not establish broader development-tool or integration capability.

Production capacityThe supplier reports a 9,891 m² manufacturing plant, inventory capability, lead times within 15 working days during both peak and off-season periods, and a broad cable product range. It also states that there is no valid contract with related subcontractors for manufacturing capacity, which is a capacity-governance limitation, but the direct evidence still supports established production capability.

Customization capabilityThe supplier explicitly reports OEM services for well-known brands, and its business scope includes research and development of new cable product technology. These statements support customization and product-development capability, although no specific customized project examples or technical customization parameters are provided.
