SummaryCrrc Yangtze Co., Ltd is identified as a China-based manufacturer/factory in Wuhan, Hubei, supplying wagon-related products for transportation. It demonstrates professional technical R&D capability, 3D software design, customization, ODM services, recent product development, and OEM experience with well-known brands. Manufacturing is supported by valid contracts with associated subcontractors and in-stock capability. Quality and management evidence includes ISO9001:2015, ISO45001:2018, and ISO14001 certifications, documented corrective-action and complaint-handling procedures, quality assurance, and material traceability. However, the supplier has no available SDK, overseas warehouse, overseas showroom, overseas agents or branches, and no reported offline trade-show participation. Financial records are indicated for the stated years, but no substantive financial performance evidence is provided.
Supplier typeThe supplier is classified as a manufacturer/factory and a combined company, with its business located in Wuhan, Hubei, China. Its stated commercial focus is transportation and its product keyword is wagon, directly supporting a manufacturing-oriented supplier profile.
CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications. These explicitly evidence certifications covering quality, occupational health and safety, and environmental management.
After-Sales capabilityThe supplier has documented procedures and followed records for customer complaints and corrective/preventive actions, plus quality assurance and material traceability. However, it has no overseas warehouse, showroom, agent, or branch, so the evidence supports structured service handling but not broad overseas service coverage.
R&D capabilityThe supplier reports professional technical R&D capability, 3D software design services, recent new-product development, ODM services, and OEM service for well-known brands. The absence of an available SDK is a specific limitation, but the broader evidence supports product and design innovation capability.
Production capacityThe supplier is identified as a manufacturer/factory, has valid manufacturing-capacity contracts with associated subcontractors, and reports in-stock capability. It also maintains written procedures and records for assessing service capability, although the stated lead-time entry is inconsistent and cannot be reliably interpreted as a precise performance measure.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, in conjunction with 3D software design services. This directly demonstrates a broad range of customization options.
Client casesThe supplier reports providing OEM services for well-known brands, which is direct evidence of experience serving recognizable customers. No specific customer names, project details, quantities, or performance outcomes are provided, so the breadth and quality of these cases cannot be assessed further.
