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. Trade records show three single-transaction product entries involving a buyer in the Philippines, providing limited customer-case evidence. Financial strength, innovation output, customization capability, and broader customer performance cannot be conclusively assessed...

Supplier typeThe supplier is explicitly classified as a factory and Manufacturer/Factory, with the legal name Qingdao Dadi Energy Co., Ltd. and a limited-company structure in China. This directly supports classification as a manufacturing supplier rather than a trading-only entity.

CertificationsThe supplier lists BSCI, ANSI/ESD, ASME, ISO 14001, and ISO 9001 under supplier management-system certifications. The provided data does not include certificate numbers, issuing bodies, scope, or validity dates, but it explicitly records multiple certifications.

After-Sales capabilityThe supplier states that it provides quality guarantees for all products and service before and after sales. However, no evidence describes response procedures, warranty duration, service personnel, repair capability, or support performance.

Production capacityThe supplier states that its Qingdao facility exceeds 100,000 square meters, operates 10 production lines, and produces wire and cable products at substantial stated volumes. Its product scope covers electric wire, power cable, solar cable, and related cable categories, supporting a positive assessment of production breadth and capacity.
