AI-Powered supplier vetting

SummaryTENLEE ELECTRIC GROUP CO., LTD is identified as a China-based manufacturer/factory in Zhejiang, offering electrical equipment and related testing products. It reports ISO 9000, ANSI/ESD, and ISO 9001 certifications, annual capacities across several electrical product categories, and substantial export activity. Its documented strengths include sample-based customization, product breadth, and stated production resources. However, the supplier reports no available SDK, no new products in the past year, no ODM or popular-brand OEM services, no inventory, overseas warehouse, overseas showroom, overseas agents, or branches. Several controls remain unverified or incompletely documented, including raw-material traceability, outsourcing procedures, contracts, environmental documentation, quality assurance, complaint handling records, and corrective-action records. The stated employee count conflicts with the separately reported quality-control and R&D staffing ranges, so organizational capacity requires...

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and a limited company based in Ningbo, Zhejiang, China. It states that it is not part of a larger company group and reports a broad electrical-product scope.

CertificationsThe supplier reports holding ISO 9000, ANSI/ESD, and ISO 9001 certifications. These certifications provide explicit evidence of formal management-system coverage, although the slices do not specify certificate validity dates or scope.

R&D capabilityThe supplier reports no available SDK, no new products during the past year, and no ODM service. It does provide sample-based design customization and reports R&D engineer experience of 6–10 years, but the explicit absence of recent product development and SDK support indicates limited demonstrated innovation capability.

Production capacityReported annual capacities include 5,000 load break switches, 1,000 switchgear units, 4,000 circuit breakers, 5,000 transformers, and 1,200 substations. The supplier also identifies itself as a manufacturer and reports quality-control staffing of 11–20, although this conflicts with the stated total employee count of two and should be verified.

Customization capabilityThe supplier explicitly offers customization from samples as a design service. However, it does not provide ODM services and does not provide OEM services for popular brands, so its customization capability is demonstrated but limited in scope.
