AI-Powered supplier vetting

SummaryQingdao Oyang Machinery Equipment Co., Ltd. is identified as a professional technical supplier offering 3D software design and sample-based customization, with Waste Incinerator listed as its primary product. It has documented procedures for service assessment, corrective actions, complaint handling, finished-product inspection, and quality-control recordkeeping. However, the supplier reported no new products in the past year, no ODM service, no SDK, and no raw-material traceability identification. Manufacturing evidence indicates one production line and no continuous quantity reconciliation for each batch or production lot. International trade experience is four years, with two export-trade staff and 41%–50% of sales from exports. No overseas warehouse, showroom, overseas branch or agent, or offline trade-show participation was reported. The provided audit record was conducted by TUVRHEINLAND, but its evaluation result and audit type are not interpretable from the supplied values alone.

Supplier typeThe supplier is explicitly described as a professional technical supplier and offers intelligent instruments, power transmission and distribution control equipment, electronic equipment, and waste-treatment-related products. Waste Incinerator is identified as the primary product, indicating a technical equipment and machinery supplier rather than a general trading-only entity.

After-Sales capabilityThe supplier has a documented and followed procedure for handling customer complaints, as well as written procedures and records for service-capability assessment and corrective/preventive actions. Nevertheless, it reports no overseas warehouse, showroom, overseas agent or branch, and no specific repair, spare-parts, or response-time capability is provided.

R&D capabilityThe supplier provides 3D software design services and has R&D capability described as customization from samples. Conversely, it reported no new products during the past year, no ODM service, and no available SDK, which limits evidence of independent or platform-based innovation.

Customization capabilityCustomization from samples is explicitly listed as the design service provided, and the supplier also provides 3D software design services. These statements directly support sample-based customization capability, although they do not establish the range, complexity, or delivery performance of customized projects.
