AI-Powered supplier vetting

SummaryShandong Yuyun Sanhe Machinery Co., Ltd. is identified as a Chinese manufacturer/factory and trading company producing ventilation, cooling, heating, humidifying, greenhouse, and livestock equipment. The company reports integrated design, manufacturing, installation, sales, and after-sales service, ISO 9001 certification, more than 10 production lines, 6–10 R&D engineers, and 6–10 quality-control staff. It has reported export activity since 2007, self-operated import/export rights, shipments from Qingdao, and exports to more than 70 countries. Evidence supports established manufacturing, export, and technical capabilities. However, the provided information does not sufficiently verify financial credibility, product-customization capability, or a broad set of identifiable customer cases.

Supplier typeThe supplier is explicitly described as a professional manufacturer and is classified as a factory, manufacturer/factory, trading company, and other business entity. Its stated operations cover design, production, sales, installation, and after-sales service, indicating a manufacturing-led supplier rather than only an intermediary.

CertificationsThe supplier reports ISO 9001 certification, and separately states that its products have passed CE, CCC, and ISO9001 certification. These stated certifications provide explicit evidence of quality-management and product-compliance credentials, although the supplied slices do not include certificate numbers or validity dates.

After-Sales capabilityThe company explicitly includes after-sales service in its integrated business scope, and its description also includes installation and sales. This supports the existence of an after-sales service function, but no detailed service network, response-time commitment, or staffing information is provided.

R&D capabilityThe supplier describes strong technical strength, cooperation with several universities, and technology innovation and product R&D platforms. It also reports 6–10 years of total R&D-engineer experience and advanced CNC and laser-cutting equipment, supporting meaningful innovation capability.

Production capacityThe supplier reports more than 10 production lines, annual productivity of 100,000 exhaust-fan sets and 25,000 cooling-pad units, and additional ventilation and heating output. Its product scope includes ventilation, cooling, heating, greenhouse, and livestock equipment, indicating substantial production breadth and capacity.

Client casesThe company states that its products have been exported to more than 70 countries, and the trade information identifies REHMAN BROTHERS as an associated buyer and Qingdao as an origin port. This supports international market exposure, but the provided evidence contains only one named buyer and does not provide detailed customer case studies or verified project references.
