AI-Powered supplier vetting

SummaryQingdao Machine and Tyre Sourcing Limited is a China-based trading company specializing in sourcing tyres, wheels and inner tubes. The supplier reports export activity since 2000, with 90% of sales from exports, broad global market coverage, and quotation terms including CFR, FOB and CIF. Its stated product portfolio covers passenger, truck, OTR, agricultural, industrial and motorcycle tyres. Supplier information also reports ISO 9000 certification, 50 R&D engineers, 50 quality-control staff and more than 10 production lines, although the company is identified as a trading company and the factory information appears separately. Reported fulfilment times are within 15 working days in off-peak periods and one month during peak periods. The slices do not provide sufficient evidence to assess after-sales service, financial credibility, customization capability or customer cases.

Supplier typeThe supplier is explicitly identified as a trading company or service company, named Qingdao Machine and Tyre Sourcing Limited, operating from China. Its stated role is sourcing Chinese tyres, wheels and inner tubes for clients rather than being clearly identified as the direct manufacturer.

CertificationsThe supplier information explicitly lists ISO 9000 certification for its management systems. No further certification scope, issuing body or validity details are provided, but the stated certification is positive evidence for this field.

R&D capabilityThe supplier information reports 50 R&D engineers, which is explicit evidence of dedicated R&D resources associated with the supplier information. Nevertheless, no details are provided on patents, new product development, proprietary technology or recent innovation outcomes.

Production capacityThe supplier information reports tyre output of 3,800,000 sets, more than 10 production lines, 50 quality-control staff, and stated lead times of within 15 working days off-peak and one month during peak season. Because the entity is also identified as a trading company and the factory is listed at a separate Jiangsu location, these figures support access to substantial production capacity but do not conclusively establish direct ownership of the manufacturing facilities.
