AI-Powered supplier vetting

SummaryTaizhou Qida Cnc Cutting Tools Co.,Ltd. is a China-based limited company operating in tools and industrial equipment. The evidence identifies it as both a manufacturer/factory and a trading company, with CNC turning tools and related carbide tooling among its offerings. It reports 15 years of industry expertise, integrated R&D, production, sales, after-sales service, and technical support, but only one R&D engineer and no new products launched in the past year. Customization is broadly supported, including sample-, design-, full-, minor-, and flexible customization. Quality-system evidence is incomplete: quality assurance and traceability statuses are unknown, and the supplier reports zero quality-control testing equipment. An SGS audit record exists with a stated validity period from June 4, 2025 to June 3, 2026, but the evaluation result is recorded as 0 without interpretation. Financial credibility cannot be fully assessed from the available non-financial evidence. No customer cases are provided.

Supplier typeThe supplier is identified as a limited company in China and is described as both a Manufacturer/Factory and a Trading Company. Its stated scope covers CNC turning tools and industrial equipment and components, with no indication that it belongs to a larger corporate group.

After-Sales capabilityThe supplier explicitly presents after-sales service, technical support, product selection, and technical assistance as part of its service model. It also states that it has a complaint-handling procedure, but no written records are available, so execution effectiveness is only partially substantiated.

R&D capabilityThe supplier has one R&D engineer responsible for R&D, product improvement, and production-site support, and R&D audit documentation is available. Against this, no new products were launched in the past year and the supplier reports zero R&D patents, indicating limited demonstrated innovation output.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. Its stated end-to-end service model also includes design support and technical assistance, providing direct evidence of broad customization capability.
