AI-Powered supplier vetting

SummaryChangzhou Shanqiu Machinery Equipment Co., Ltd. is a China-based manufacturing factory established in 2012, focused on filter-bag and filter-cartridge production equipment, including sewing, ultrasonic welding, hot-air welding, cutting, and automated production lines. It operates from a 2,560 m² facility with 21 employees, reports 6–10 quality-control staff, and states that it has self-operated import and export rights. The supplier exports to multiple global regions, with exports accounting for 41%–50% of total sales, and reports one-month order fulfillment in both peak and off-peak seasons. Its stated strengths include product specialization, manufacturing and service activities, and product-related R&D experience. However, no management-system certifications are reported, R&D engineering experience is limited to two years, and the provided information does not sufficiently establish after-sales capability, customization capability, financial credibility, or a broad customer-case record.

Supplier typeThe supplier is identified as a factory and manufacturing enterprise in Changzhou, Jiangsu, China. Its business scope covers industrial equipment, components, services, and manufacturing machinery, while its legal form is described as a limited company.

CertificationsThe supplier explicitly reports no supplier management-system certification ("NIL"). This is direct evidence that no such certification is documented in the provided information.

R&D capabilityThe supplier emphasizes research, innovation, and product development, and offers multiple specialized technologies including automatic production lines, ultrasonic welding, hot-air welding, and precision cutting equipment. However, only two years of R&D engineer experience is reported, so the evidence supports product-development activity but not a clearly strong innovation advantage.

Production capacityThe supplier operates a 2,560 m² manufacturing plant, identifies itself as a factory, produces several categories of filter-bag and filter-cartridge machinery, and reports one-month fulfillment during both peak and off-peak periods. Its 6–10 quality-control staff and export operations further support operational capability.
