AI-Powered supplier vetting

SummaryChangzhou Suma Precision Machinery Co., Ltd. is a China-based limited company established in 2012, with 23 employees and operations in manufacturing-related machinery. It supplies bearings, clutches, backstop clutches, and washers, and reports machining, CNC grinding, and CNC turning equipment. The supplier demonstrates broad customization, recent new-product activity, ODM capability, and OEM service for recognized brands. Quality controls include product inspection instructions, raw-material traceability, and maintained procedures. Export experience is substantial, with 90% of sales reported as exports and 11 years of exporting, but no overseas warehouses, showrooms, agents, or branches. Service governance is weakly documented: no written procedures or records were reported for supplier assessment, corrective actions, or complaint handling. The provided slices do not establish certifications, detailed financial strength, or named customer cases. An audit by CTI is recorded, but the evaluation result is...

After-Sales capabilityThe supplier accepts multiple quotation and payment terms and reports average peak- and off-season lead times within 15 working days. However, it has no written procedures or records for complaint handling or corrective and preventive actions, and it has no overseas warehouse, showroom, agent, or branch; these facts indicate limited documented after-sales infrastructure.

R&D capabilityThe supplier reports that it had new products during the past year and provides ODM services, supporting active product-development capability. It also offers customization from designs and samples, but has no available SDK, so the innovation evidence is positive but not comprehensive.

Production capacityReported production resources include a machining center, CNC grinding machine, and CNC lathe. Finished products are inspected using instructions that are uniformly followed, with quality assurance, raw-material traceability, and maintained quality-control records; however, the slices do not quantify capacity or output.

Customization capabilityThe supplier explicitly provides minor customization, full customization, customization from customer designs, and customization from samples. The same capabilities are reported in both the R&D and design-service information, providing direct evidence of broad customization coverage.
