AI-Powered supplier vetting

SummaryQingdao Qingke New Materials Technology Co., Ltd. is identified as a professional technical supplier with R&D, ODM, OEM, 3D design, and broad customization capabilities. It reports seven production lines, valid manufacturing contracts with associated subcontractors, in-stock capacity, documented finished-product inspection procedures, and an off-peak lead time within 15 workdays. The supplier has introduced new products within the past year and provides environmental and fire-safety documentation. However, no supplier-management-system certification is reported, and the company lacks overseas warehouses, showrooms, agents or branches, and offline trade-show experience. Export sales represent 41%–50% of total sales, while the stated primary market is domestic. Financial records are indicated for 2022–2024, but their results are not provided. Customer-specific evidence is limited to stated OEM service for well-known brands.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and reports R&D, 3D software design, ODM, OEM, and manufacturing-related capabilities. Its broad technical and production-service profile supports classification as a professional technical/manufacturing supplier.

CertificationsSupplier-management-system certification is explicitly reported as NIL. Although the supplier has a factory environmental impact assessment report and conducts regular fire drills, these do not establish possession of a management-system certification.

R&D capabilityThe supplier reports professional technical R&D capability, 3D design services, new products launched within the past year, and ODM services. It has two years of total R&D engineer experience and no available SDK; these details support active product development but do not establish the overall strength of innovation resources.

Production capacityThe supplier reports seven production lines, a broad set of processing and assembly equipment, valid manufacturing contracts with associated subcontractors, in-stock capacity, standardized finished-product inspection instructions, and an off-peak lead time within 15 workdays. These are explicit indicators of organized production capability.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization, together with 3D software design services. The evidence supports a broad customization offering.
