AI-Powered supplier vetting

SummaryThe supplier demonstrates established manufacturing, quality-control, certification, customization, export, and after-sales capabilities. Evidence includes ISO9001:2015, ISO45001:2018, ISO14001, CE capability, tested switch and fuse products, documented complaint and service procedures, traceability, and two-year product guarantees. It operates one production line with 11–20 quality-control staff and reports substantial product-specific output. The supplier supports customization from samples and designs and exports 90% of total sales, primarily to Southeast Asia and the Mideast. Financial credibility cannot be assessed because the provided financial fields contain only years rather than financial results or indicators. Innovation capability is also insufficiently demonstrated, and no customer cases are explicitly identified.

Supplier typeThe supplier appears to be a manufacturing supplier with dedicated metalworking and forming equipment, one production line, stated product output, valid manufacturing contracts with affiliated subcontractors, inventory capability, and overseas warehouse and showroom services. The evidence supports a manufacturer with export-oriented fulfillment capabilities.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, along with CE certification capability. Its IST-12KV/400A off-load switch passed testing by the Central Power Research Institute High-Voltage Laboratory in India, and its 12KV 8KA drop-out fuse passed ASTA testing in 2015.

After-Sales capabilityThe supplier has an after-sales service department, documented service processes, local service personnel who can visit customer sites, feedback collection with customer signatures, direct company intervention for special conditions, and a stated two-year product guarantee. Complaint handling, corrective/preventive actions, and supplier service procedures are documented and followed, with inventory and overseas warehouse capabilities also reported.

Production capacityProduction resources include hydraulic shearing and bending machines, stamping and pressing equipment, grinding, lathes, milling, and drilling equipment. The supplier operates one production line, has 11–20 quality-control staff, reports product-specific output across fuses, disconnectors, pole-line hardware, insulators, and surge arresters, and maintains quality assurance, traceability, and controlled inspection procedures.

Customization capabilityThe supplier explicitly supports customization from samples and from customer designs. This is direct evidence of product customization capability, although the provided information does not specify engineering scope, tooling lead times, or technical limits.
