AI-Powered supplier vetting

SummaryQingdao Dingsheng Yitong Industry and Trade Co., Ltd. is identified as a China-based trading company focused on motorcycle tires and inner tubes. The provided information describes R&D activity, product customization, claimed annual capacity of 3 million outer tires and 10 million tubes, and export activity beginning in 2021, with 90% of total sales reportedly from exports. The supplier states that it holds ISO 9001:2015, CCC, U.S. DOT, and EU E-mark certifications. It also claims product strengths including carcass strength, wear resistance, durability, and diverse tread patterns. However, the evidence does not substantiate after-sales processes, financial credibility, named customer cases, or independently verified production capability. There is also a discrepancy between the stated founding year of 2008 and the registered establishment date of 2026-01-16.

Supplier typeThe supplier is explicitly classified as a trading company and operates in auto, motorcycle parts, and accessories, with motorcycle tires and inner tubes identified as key products. Its company description also presents activities covering R&D, production, and sales, but the formal entity classification remains trading company.

CertificationsThe supplier states that it has obtained ISO 9001:2015 quality-system certification, CCC certification, U.S. DOT certification, and EU E-mark certification (E13). These claims provide explicit evidence of multiple relevant certifications, although no certificate numbers, validity dates, or verification documents are provided.

R&D capabilityThe supplier states that it promotes product innovation and process upgrades, supported by an advanced formulation laboratory, a professional R&D team, unique rubber formulations, and cord-structure designs. These statements explicitly indicate innovation-related resources and activities, though no patents, development metrics, or independently validated results are provided.

Customization capabilityThe supplier explicitly states that it can tailor production solutions to individual requirements involving size, performance, and tread patterns. This directly supports customization capability for differentiated tire products.
