AI-Powered supplier vetting

SummaryXuzhou Jinteng is identified as a professional technical supplier with customization capabilities and stated technical support for production and after-sales service. It holds ISO 9001 and ISO 14001 certifications, and its company description references more than 500 overseas projects and CE certification. Production evidence includes three production lines and reported transformer output of 20,000 pieces. However, the supplier does not provide 3D software design, ODM, SDK, or popular-brand OEM services, and no new products were reported in the past year. Quality-control resources appear limited or inconsistently documented: one slice reports one quality-control inspector and no test equipment, while another reports 6–10 quality-control staff. No overseas showroom, agents, branches, or offline trade-show participation were reported. Financial credibility cannot be assessed because financial figures are excluded.

Supplier typeThe supplier is explicitly identified as a professional technical supplier. Its stated business scope includes vehicles, batteries and battery parts, capacitors, generators, charging stations, and metal forming, indicating a broad industrial and smart-device-related product scope.

CertificationsThe supplier reports ISO 14001 and ISO 9001 certification. Its company description also references CE certification and compliance with the ISO 9001 quality and ISO 14001 environmental management systems, providing explicit evidence of relevant certifications.

R&D capabilityThe supplier is described as a professional technical supplier and has one R&D engineer providing technical support. Nevertheless, it reports no new products in the past year, no ODM service, no SDK availability, and no 3D software design service, indicating limited evidence of current product innovation capability.

Production capacityThe supplier operates three production lines and reports transformer output of 20,000 pieces, with a stated factory location. The available records also show one quality-control inspector and zero quality-control test equipment in one assessment, while another reports 6–10 quality-control staff; this supports production activity but leaves quality-production infrastructure inconsistently documented.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, flexible customization, and minor customization. Its technology engineer is also responsible for confirming customer requirements and supporting production, directly supporting its customization process.

Client casesThe supplier states that it has successfully implemented more than 500 overseas projects and helped customers improve operational efficiency. These are explicit project-experience claims, although the provided information does not identify specific customers, industries, or project outcomes.
