AI-Powered supplier vetting

SummaryMafal (Shanghai) Machinery Limited is identified as a Chinese manufacturer/factory operating in Shanghai and supplying construction machinery, industrial equipment, and related parts. The supplier reports multiple ISO certifications, 41–50 years of combined R&D engineer experience, 6–10 quality-control staff, and 10 production lines. It began exporting in 2013, reports that 51%–70% of sales come from exports, and accepts several payment methods. The available trade records show individual transactions involving shafts, spare tyres, turbochargers, and gearboxes with buyers in Uganda and Cameroon, but the evidence is limited in volume. The provided information supports production infrastructure, certification, export experience, and identifiable customer transactions; it does not sufficiently establish after-sales service performance, financial credibility, customization capability, or a broad customer portfolio.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and operates in industrial equipment, tools, transportation, and manufacturing machinery. Its listed products include excavators, cranes, loaders, bulldozers, trucks, rollers, graders, forklifts, and related machinery, indicating alignment with industrial machinery supply.

CertificationsThe supplier reports ISO 9000, ISO 14000, ISO 9001, ISO 14001, and ISO 20000 certifications. These stated certifications provide explicit evidence of formal quality, environmental, and information-management system credentials, although the slices do not provide certificate numbers, issuing bodies, or validity dates.

Production capacityThe supplier reports 10 production lines, 6–10 quality-control staff, 41–50 years of R&D engineer experience, and annual production output within the stated range. Its broad construction-machinery product portfolio further supports manufacturing capability across multiple equipment categories.

Client casesTrade records identify BIDCO Uganda LIMITED as a buyer for shafts, turbochargers, and gearboxes, and LENН COMPANY LIMITED as a buyer for spare tyres; the recorded destinations include Uganda and Cameroon. Each listed product record shows one transaction, so the evidence confirms identifiable customer activity but does not demonstrate a broad or extensively verified customer base.
