AI-Powered supplier vetting

SummaryTesite Container House Co., Ltd. is a container-house manufacturer with stated research and development, production, sales, and service activities. It operates seven production lines, reports annual output of 15,000 expandable container houses, 20,000 folding container houses, and 30,000 folding houses, and exports mainly to South America, Europe, and Australia. The supplier offers extensive customization, ODM services, and OEM services for well-known brands. Its factory has a stated area of 17,000 square meters and includes cutting, galvanizing, welding, spraying, assembly, interior decoration, and quality inspection processes. Quality-related evidence is mixed: customer-complaint handling has documented procedures and records, while supplier-service assessment and corrective-action processes lack written procedures or records. No explicit certification names or customer case details are provided. Financial information is insufficient for assessment.

Supplier typeThe supplier describes itself as an enterprise specializing in the research and development, production, sales, and service of container houses. Its stated business scope also includes metal structures, metal products, doors and windows, photovoltaic equipment, outdoor products, and related technical and import/export activities, indicating a manufacturer with broader related product and service coverage.

After-Sales capabilityThe supplier states that it provides thoughtful customer service and has staff available to discuss customer requirements. The service-capability assessment records show a clear procedure and followed records for handling customer complaints, but no comparable documented procedures are available for supplier-service assessment or corrective and preventive actions.

R&D capabilityThe supplier reports new products during the past year, ODM availability, and three years of total R&D engineer experience. Its stated R&D and production activities cover container houses, but it does not have an available SDK; the evidence supports product-development capability but not a software-development capability.

Production capacityThe supplier reports seven production lines, a 17,000-square-meter factory, and production processes covering cutting, galvanizing, welding, spraying, assembly, interior decoration, and quality inspection. Reported annual capacities are 15,000 expandable container houses, 20,000 folding container houses, and 30,000 folding houses, supported by three quality assurance and quality control inspectors and 11–20 quality control staff.

Customization capabilityBoth R&D and design-service information explicitly lists customization from samples, customization from designs, minor customization, flexible customization, and full customization. This is reinforced by the supplier’s stated ODM service availability, indicating broad customization coverage.
