AI-Powered supplier vetting

SummaryZhengzhou Qianzhuo Auto Parts Co., Ltd. is a China-based trading company and manufacturer/factory focused on automotive parts, engine spare parts, and diesel engines. It is a limited company with two employees and no stated group affiliation. The supplier provides ODM, OEM for well-known brands, and design-based customization, but has one R&D engineer, launched no new products in the last year, and lacks an available SDK. Service-control documentation is weak: no written procedures or records were reported for supplier-service assessment, corrective actions, or complaint handling. Financial information identifies reporting years through 2023 but provides no performance values, so credibility cannot be determined. No Fortune 500 cooperation is reported, while repeat-buyer preference is stated at 10%–30%. Audit-related information names TÜV Rheinland and provides a report period from May 24, 2024 to May 23, 2025, but does not identify a certification held or explain the evaluation result.

Supplier typeThe supplier is identified as both a Trading Company and Manufacturer/Factory, with limited-company status and operations in Zhengzhou, Henan, China. Its stated business and product scope centers on automotive parts, engine spare parts, and diesel engines.

After-Sales capabilityThe supplier has 10 qualified service-capability suppliers and provided some supplier names, but it reported no written procedures or records for service assessment, corrective and preventive actions, or effective customer-complaint handling. This is explicit evidence of weak documented service controls.

R&D capabilityThe supplier has one R&D engineer and offers ODM services, but it launched no new products in the last year and has no available SDK. These facts indicate some development capability but limited demonstrated innovation output.

Customization capabilityThe supplier explicitly supports customization from designs, provides ODM services, and offers OEM services for well-known brands. These statements directly demonstrate customization and outsourced-design manufacturing capability.
