AI-Powered supplier vetting
SummaryThe supplier is a Shanghai-based limited trading company with 41 employees, focused on fasteners and related metal, mechanical, plastic, rubber, electrical, and photovoltaic products. It offers sample-, design-, and full-customization services, as well as ODM and OEM services, and reports export sales of 71%–90%. In-stock service is available, but there is no overseas warehouse, showroom, agent, or branch. Financial records are identified for 2022–2024, but no financial values or performance conclusions are provided. Service-process evidence is weak: no written corrective/preventive-action or complaint-handling procedures or records are available, while quality-assurance status and fire-drill status are unknown. No certifications, customer cases, or production facilities are explicitly documented.
Supplier typeThe supplier is identified as a limited company and trading company, with 41 employees, no stated parent-group affiliation, and a Shanghai registered and physical address. Its stated product scope centers on fasteners and related industrial products.
After-Sales capabilityThe supplier has in-stock service capacity, but it has no overseas warehouse, showroom, overseas agent, or branch. More importantly, no written corrective/preventive-action procedures or records and no written customer-complaint procedures or records are available, indicating a documented after-sales process is not demonstrated.
R&D capabilityThe supplier lists research and development of metal products and hardware products, and offers ODM services. However, no SDK is available, and the information does not provide measurable R&D resources, patents, or development outcomes; the documented capability is therefore limited but present.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, and full customization, together with ODM and OEM services for popular brands. These statements provide direct evidence of broad customization and design-manufacturing service capability.
