AI-Powered supplier vetting

SummaryJiangsu Tianhua Transformer Co., Ltd. is a transformer manufacturer involved in production, development, sales, and related import/export activities. It reports five production lines, a 6,150.0 m² manufacturing plant, 100% finished-product inspection, and five quality assurance and quality control inspectors. The supplier supports customization from samples and designs, offers OEM services for well-known brands, and maintains documented procedures for service assessment, corrective and preventive actions, and complaint handling. ISO9001:2015, ISO45001:2018, and ISO14001 certifications are reported. However, it has no valid manufacturing-capacity contract with related subcontractors, no outsourcing standard operating procedure, no ongoing batch quantity reconciliation, no overseas warehouse or showroom, and no available SDK. The provided information does not establish specific customer cases or independently verify financial strength.

Supplier typeThe supplier is identified as a transformer manufacturer whose business covers power transformer and distribution cabinet manufacturing and sales, along with related import and export activities. Its company description also identifies it as a high-tech enterprise specializing in transformer production, development, and sales.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, and states that it follows the ISO9000 quality management system. These records provide explicit evidence of quality, occupational health and safety, and environmental management certification.

After-Sales capabilityThe supplier has written procedures and records for service-capability assessment, corrective and preventive actions, and customer complaint handling. It also reports in-stock capability and accepts multiple quotation and payment terms, but it lacks overseas warehouse and showroom services; the evidence supports service-process capability but not comprehensive overseas after-sales coverage.

Production capacityThe supplier reports a 6,150.0 m² manufacturing plant, five production lines, dedicated equipment for slitting, shearing, punching, foil winding, coil winding, and heating, plus in-stock capability and 100% finished-product inspection. Capacity-control weaknesses remain because there is no valid manufacturing-capacity contract with related subcontractors, no outsourcing SOP, and no ongoing batch quantity reconciliation.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This indicates broad stated adaptability to customer-specific transformer requirements.
