AI-Powered supplier vetting

SummaryQingdao Kingworld Control Co., Ltd. is identified as a China-based limited trading company and manufacturer/factory associated with motorcycle and other tyre products. Evidence indicates a factory in Qingdao, four production lines, 11–20 quality-control staff, ISO 9001 certification, and stated motorcycle-tyre output of 3,000,000 pieces annually. The supplier reportedly began exporting in 2009, with exports representing 71%–90% of total sales, and states that it has self-operated import/export rights. Its product scope includes motorcycle, ATV, bicycle, wheelbarrow, car, truck, forklift tyres and tubes. Export-related records identify buyers in Peru and Vietnam, although the available evidence does not establish after-sales processes, customization capability, financial strength, or a broad verified customer portfolio. The descriptions also reference exports to more than 30 countries and additional certifications, but these claims are supplier-provided statements.

Supplier typeThe supplier is described as both a trading company and manufacturer/factory, with a factory located in Huangshang Industrial Park, Qingdao. Its stated specialization is motorcycle tyres and tubes, while its product keywords cover several tyre and tube categories.

CertificationsISO 9001 certification is explicitly recorded, and the company description additionally claims CCC, U.S. DOT, and SONCAP certifications. ISO 9001 provides direct evidence of a certified quality-management system; the additional certifications are presented as company claims without separate verification in the supplied data.

Production capacityProduction capability is supported by a stated factory location, four production lines, 11–20 quality-control staff, and annual motorcycle-tyre output of 3,000,000 pieces. The supplier also states that it has operated since 2009 and specializes in motorcycle tyres and tubes.

Client casesTrade records identify DISTRIBUCIONES BICI & MOTOS E I R L in Peru and CÔNG TY CỔ PHẦN TÂN KHẢI in Vietnam, while the company claims exports to more than 30 countries. These provide evidence of named buyer and export activity, but the data does not establish order scale, repeat business, performance outcomes, or independently verified case studies.
