AI-Powered supplier vetting

SummaryNantong Ningyuan Automation Technology Co., Ltd. is presented as an R&D-oriented Li-ion battery innovation enterprise with one production line and export experience spanning 12 years. It provides sample-based, minor, full, and flexible customization, as well as ODM and OEM services for well-known brands. Production and service controls include written procedures for inspection, corrective and preventive actions, customer complaints, and supplier assessment. The supplier reports inventory capability, valid contracts with associated subcontractors, and lead times within 15 working days in both peak and off-peak seasons. However, it lacks an available SDK, overseas warehouses, overseas showrooms, overseas agents or branches, and documented R&D design-input/output/review/verification/validation records. No certification information or specific customer case details are provided. Financial information is present only as year references, so financial credibility cannot be determined.

Supplier typeThe supplier is identified as Nantong Ningyuan Automation Technology Co., Ltd., an innovation enterprise focused on the R&D and application of Li-ion batteries. It operates one production line and serves export markets in South America, Southeast Asia/Mideast, Europe, and North America.

After-Sales capabilityThe supplier has written procedures and records for handling customer complaints and corrective/preventive actions, and accepts multiple service payment terms. However, it has no overseas warehouse, overseas showroom, overseas agents, or branches, which limits documented overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year, ODM capability, and R&D software skills in AutoCAD, Pro/E, and SolidWorks. Its R&D documentation is not available for audit, and no SDK is available, so the evidence supports active design capability but not a fully documented or software-enabled innovation system.

Production capacityThe supplier operates one production line, reports inventory capability, valid contracts with associated subcontractors, and lead times within 15 working days in both peak and off-peak seasons. Written procedures cover finished-product inspection, supplier assessment, quality assurance, complaints, and corrective actions, while export experience is stated as 12 years.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, minor customization, and flexible customization. It also provides ODM services, indicating capability to support both modification and original product design requirements.
