AI-Powered supplier vetting
SummaryThe supplier operates in steel, rubber products, instruments and meters, and lubricants, with stated import and export authorization. It reports substantial export activity, flexible customization, quality-management certifications, 41–50 quality-control staff, and production output data. However, raw-material and quality traceability status is unknown, quality-control test equipment is listed as zero, and R&D audit documentation is unavailable. Overseas service coverage is limited, with no overseas showroom, agent, branch, or offline trade-show participation. Service procedures exist but lack written records. Financial information is inconsistent across the provided records, so financial credibility cannot be confirmed. No evidence of named customer cases or major-brand OEM service is provided.
Supplier typeThe supplier covers steel, rubber products, instruments and meters, and lubricants, and states that it has self-operated import and export rights. Export sales are reported at 71%–90%, although the stated exporting history is 0 years, creating a record inconsistency.
CertificationsThe supplier reports TS 16949, ISO 9001, and ISO 14001 certifications. These are explicit certification holdings relevant to automotive quality, general quality management, and environmental management.
After-Sales capabilityThe supplier has no overseas showroom, agent, branch, overseas-service country coverage, or offline trade-show participation. It reports service procedures for corrective actions and complaints, but no written records, while lead times are stated as within 15 workdays in both peak and off-season.
Production capacityThe supplier states that it supports both small-batch customization and large-scale orders, reports 41–50 quality-control staff, and provides annual production-output information. However, quality-control test equipment is listed as zero, which is an explicit production and quality-control deficiency.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and states that R&D responsibilities are customized to customer needs. This supports broad customization capability, although the limited R&D documentation reduces verification depth.
