AI-Powered supplier vetting

SummaryThe supplier is a manufacturer of EN124-series ductile iron trench and manhole covers and related metal products, with stated production capacity of 25,000 tons for manhole cover grilles and export activity focused on domestic and European markets. It holds an ISO9001:2015 certificate and reports a quality management system, although separate investigation data identifies unknown quality-assurance and traceability status, zero quality-control test equipment, and no documented complaint, supplier-service, or corrective-action procedures. The supplier offers extensive customization, including sample-, design-, full-, minor-, and flexible customization, supported by one R&D engineer. However, it does not provide 3D software design services and is not classified as a professional technical supplier. Overseas service infrastructure is limited: no overseas warehouse, showroom, agent, branch, or offline trade-show participation was reported. Lead time is one month in both peak and off-peak periods.

CertificationsThe supplier reports an ISO9001:2015 certificate and states that its quality management system was established in accordance with ISO9001 principles. However, other records identify the current quality-assurance and traceability status as unknown, so the certification evidence supports a positive assessment but does not establish the effectiveness of every quality-control element.

After-Sales capabilityAfter-sales and service-management evidence is weak: the supplier has no written complaint procedures or records, no documented service-capability assessment or corrective/preventive-action mechanism, no approved service-supplier list, and no overseas warehouse, showroom, agent, branch, or reported overseas-service country. These are explicit gaps in documented and overseas support capability.

Production capacityThe supplier states that it mainly produces EN124-standard ductile iron products and reports annual output of 25,000 tons for manhole cover grilles, with one-month lead times in both peak and off-peak seasons. It also claims complete production and testing equipment, but the investigation records zero quality-control test equipment, unknown traceability status, and no documented service-capability procedures, creating a conflict that prevents a fully positive quality-production assessment.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its one R&D engineer is responsible for customizing products according to customer-required dimensions, directly supporting the stated customization capability.
