AI-Powered supplier vetting
SummaryNatebon Electromechanical Industry (Jiangsu) Co., Ltd. is identified as a Chinese factory and comprehensive power-transmission-components provider, with bearing manufacturing and related industrial equipment activities. It has ISO9001:2015, ISO14001, ISO45001:2018, CE, and RoHS certifications. The supplier reports OEM service for well-known brands, inventory availability, and lead times within 15 working days in both peak and off-season periods. However, it has no available SDK, no overseas warehouse or showroom, no overseas-service-country coverage, and limited documented service-management controls. Manufacturing evidence includes one production line and a 2,973.47 m² plant, while no valid manufacturing-capacity contract with related subcontractors is reported. Export experience is one year with four experienced export-trade staff. Financial figures are excluded for privacy, and the supplied records do not provide enough non-financial evidence to establish financial credibility.
Supplier typeThe supplier is explicitly identified as a factory located in Kunshan, Suzhou, with manufacturing activities covering machine-tool functional components and accessories and bearings. Its stated commercial scope also includes industrial equipment, tools and hardware, and power-transmission components, indicating a manufacturing-oriented industrial supplier rather than only a trading company.
CertificationsThe supplier reports ISO9001:2015, ISO14001, and ISO45001:2018 certifications, together with CE and RoHS product-certification capability. These explicitly documented certifications support quality, environmental, occupational-safety, and product-compliance capabilities.
After-Sales capabilityThe supplier reports in-stock service capability and lead times within 15 working days in both peak and off-season periods, but it has no written procedures or records for service assessment, corrective and preventive actions, or customer-complaint handling. It also reports no overseas warehouse, showroom, or overseas-service-country coverage, so the evidence supports operational availability but not a well-documented or broad after-sales network.
R&D capabilityThe supplier describes independent R&D capability and emphasizes innovation and product-solution optimization. However, it explicitly reports no available SDK, so the evidence demonstrates some R&D positioning but does not establish broad technical-development or software-integration capability.
Production capacityThe supplier operates as a factory, reports a 2,973.47 m² manufacturing plant, bearing and machine-tool-component manufacturing activities, inventory capability, and one production line. However, it reports no valid manufacturing-capacity contract with related subcontractors, so production capability is evidenced but appears limited in documented scale and manufacturing-continuity support.
Customization capabilityThe supplier explicitly reports OEM services for well-known brands and has manufacturing activities in bearings and machine-tool functional components, supporting the ability to produce customer-specific industrial products. No detailed evidence is provided on customization processes, engineering resources, or customization scope beyond OEM availability.
