AI-Powered supplier vetting

SummaryChengdu Sentec Technology Co., Ltd. is a China-based limited company in Sichuan operating as both a trading company and manufacturer/factory in electrical and electronics. Its stated product range centers on industrial sensors and meters. Available evidence indicates ISO 9001 certification, more than 10 production lines, 6–10 quality-control staff, and 11–20 years of R&D engineer experience. The company describes sensor-technology R&D, intelligent factory-monitoring expertise, OEM experience, and export activity since 2011, with 51%–70% of sales from exports and self-operated import/export rights. However, several operational areas remain unverified, including overseas service facilities, 3D design, ODM/OEM details, SDK availability, sustainability documentation, customer cases, and raw-material traceability. The audit record was conducted by BV, but its evaluation result is recorded as 0 and the stated report validity ended in November 2024; the meaning of the result is not specified, so no definitive...

Supplier typeThe supplier is explicitly identified as both a Trading Company and Manufacturer/Factory, with a Limited Company ownership structure and operations in electrical and electronics. This supports classification as a hybrid trading and manufacturing supplier.

CertificationsThe supplier reports ISO 9001 certification. A BV audit is also recorded, but the audit evaluation result is listed as 0 and the report validity ended on 2024-11-15; because the meaning of the result is not provided, only the ISO 9001 holding is treated as positive evidence.

R&D capabilityThe company describes industry experts engaged in sensor R&D and innovation, a team focused on intelligent factory monitoring, and 11–20 years of R&D engineer experience. However, new-product output, SDK availability, and several specific technical-development capabilities are unknown, so the evidence supports R&D experience but not a complete innovation assessment.

Production capacityThe supplier reports operating more than 10 production lines and maintaining 6–10 quality-control staff. Its listed product scope includes pressure, temperature, liquid-level, density, flow, humidity, and wind-speed sensors/meters, providing explicit evidence of manufacturing scale and product coverage.
