AI-Powered supplier vetting

SummaryQingdao Dadi Energy Co., Ltd. is identified as a Chinese manufacturer/factory producing wires, cables, and related electrical products. The supplier reports a factory area exceeding 100,000 square meters, 10 production lines, 21–30 years of combined R&D-engineer experience, and 6–10 quality-control staff. It lists BSCI, ANSI/ESD, ASME, ISO 14001, and ISO 9001 certifications. Its stated applications include building wiring, power-grid transmission, underground mining, construction, and industrial communication control. The supplier claims product quality guarantees and before- and after-sales service, but no detailed service terms are provided. Export sales account for 41%–50%, and the supplier reports self-operated import/export rights.
