AI-Powered supplier vetting

SummaryQuanzhou Chaoyang Autoparts Co., Ltd. is a China-based limited-company manufacturer established in 2013, with 29 employees and automotive-parts-related business activities. It reports two manufacturing lines in one capacity record and three operated production lines in another, plus 6–10 quality-control staff. The supplier offers ODM services and in-stock capacity, but reports no new products in the past year, no SDK, and no OEM service for popular brands. Manufacturing controls show weaknesses: no valid manufacturing-capacity contract with its affiliated subcontractor, no ongoing batch quantity reconciliation, and no outsourcing SOP. Overseas support is limited, with no overseas warehouse, showroom, agent, or branch, and no reported offline trade-show participation. Financial records are identified for 2022–2024, but no financial results are provided. No certifications or customer cases are evidenced.

Supplier typeThe supplier is identified as a manufacturer and limited company based in Quanzhou, Fujian, China, established in 2013. Its stated scope includes automotive-parts manufacturing, remanufacturing, wholesale, retail, and mechanical component processing.

After-Sales capabilityThe supplier has in-stock service capacity and accepts several quotation and payment terms, but has no overseas warehouse, showroom, agent, or branch, serves zero stated overseas countries, and reports no written service-capability procedures or maintained records. This indicates limited documented and overseas after-sales infrastructure.

Production capacityProduction resources include two reported manufacturing lines, three operated production lines in another record, and 6–10 quality-control staff. However, the supplier reports no valid manufacturing-capacity contract with its affiliated subcontractor, no continuous batch quantity reconciliation, and no outsourcing SOP, creating explicit process-control deficiencies.

Customization capabilityThe supplier explicitly provides ODM services and operates in automotive-parts manufacturing and mechanical component processing, which supports customization-related capability. However, no detailed customization scope, engineering resources, or delivery examples are provided.
