AI-Powered supplier vetting

SummaryLiyuan Motor Ltd is a limited company founded in 1989 and described as a professional manufacturer of small and medium electric motors, while its listed product scope is diesel generating sets. It reports a 10,000-square-meter facility, advanced production and testing equipment, and CE product compliance certification. Customization and 3D software design services are available, but R&D resources are limited to one engineer, with no new products launched in the past year and no ODM or SDK capability. After-sales support includes free labor for specified repairs, debugging, and some on-site services, although the supplier has no overseas agents, branches, showroom, or documented complaint and corrective-action procedures. No financial figures are provided, so financial credibility cannot be determined. Customer evidence is limited: no Fortune 500 cooperation is reported, while repeat-buyer preference is stated at 50%–80%.

CertificationsThe supplier reports CE certification for product compliance. However, its supplier management system certification is listed as NIL, so evidence supports product-level compliance but not certified supplier-management systems.

After-Sales capabilityThe supplier states that it provides free debugging, repairs, maintenance, and certain on-site services without labor charges, with overseas users served through distributors. However, it reports no overseas agents or branches, zero countries with overseas services, and no written complaint-handling or corrective-action procedures.

R&D capabilityThe supplier identifies itself as a professional technical supplier and provides 3D software design services, but it has only one R&D engineer, launched no new products in the past year, and reports no ODM or SDK capability. These facts indicate limited demonstrated product innovation capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and 3D software design services. This provides direct evidence of broad customization support.
