AI-Powered supplier vetting

SummaryJianben Fan is a limited company with 20 employees, one production line, two quality inspectors, and stated fan productivity of 100,000 sets. It offers broad customization and maintains documented inspection, service assessment, corrective-action, and complaint-handling procedures. The supplier holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications and has a valid import/export license. Export sales account for 41%–50%, although overseas service infrastructure is absent and exporting reportedly began 0 years ago. Production controls show weaknesses: no valid manufacturing-capacity contract with related subcontractors, no inventory capability, no outsourcing SOP, and no ongoing quantity reconciliation. No SDK, popular-brand OEM capability, or customer cases are evidenced. Financial records are referenced for 2020–2022, but the provided slices do not establish financial strength.

Supplier typeThe supplier is identified as a limited company, not part of a larger company group, with 20 employees and a valid import/export license. This supports classification as an independent, legally authorized trading and manufacturing supplier, although its general trade-volume range is unknown.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, covering quality, occupational safety, and environmental management. These explicitly documented certifications are positive evidence for this field.

After-Sales capabilityThe supplier has written procedures and records for service-capability assessment, corrective and preventive actions, and customer complaints. However, it reports no overseas services, overseas warehouse, or overseas showroom, so documented service processes exist but overseas support infrastructure is limited.

Production capacityThe supplier reports one production line, fan productivity of 100,000 sets, two quality inspectors, laser cutting, bending, and welding equipment, and lead times within 15 working days in both peak and off-seasons. Countervailing deficiencies include no valid capacity contract with related subcontractors, no inventory capability, no outsourcing SOP, and no ongoing batch quantity reconciliation.

Customization capabilityThe supplier explicitly supports customization from samples and designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.
