AI-Powered supplier vetting

SummaryThe supplier is a limited company in Liaocheng, Shandong, China, supplying valves and electronic sensors with 23 employees. It identifies as a professional technical supplier and provides 3D design, sample-based customization, ODM, and OEM services. Quality processes include assurance, raw-material traceability, documented inspections, complaint handling, and corrective-action procedures. The supplier has inventory capability, testing equipment, export experience, and a high stated export share, but lacks an effective contract with related manufacturing subcontractors, overseas warehouses, overseas showrooms, and an available SDK. No new products were reported in the past year, while financial credibility and customer-case evidence remain insufficient for firm assessment.

Supplier typeThe supplier is explicitly identified as a professional technical supplier, operates as a limited company, and offers valves and electronic sensors. It also provides ODM and OEM services, indicating a product manufacturer or design-manufacturing supplier rather than a general trading-only entity.

After-Sales capabilityThe supplier states that its global service network provides timely after-sales technical services and reports a clear, followed customer-complaint procedure. However, it has no overseas warehouse or showroom, which may limit local service infrastructure, although the evidence does not establish that after-sales performance is inadequate.

Production capacityThe supplier reports inventory capability, computer-controlled CNC machines, extensive spare-parts inventory, finished-product inspection procedures, and testing equipment including salt-spray and tensile-testing machines. However, there is no valid contract between the factory and related subcontractor, creating a documented manufacturing-governance deficiency despite other production resources.

Customization capabilityThe supplier explicitly offers sample-based customization, customer-specific product design and development, 3D software design, OEM customization, and ODM services. These repeated statements provide direct evidence of customization capability for specific applications.
