AI-Powered supplier vetting

SummaryZibo Baiwang Machinery Co., Ltd. is identified as a Chinese private trading company and manufacturer/factory with a factory in Zichuan, Zibo, Shandong. The supplier reports more than 10 production lines, 41–50 quality-control staff, broad automotive and industrial product coverage, and substantial stated production capacities across brake and machinery-related products. It reports TS 16949 and ISO 9001 certifications, 90% export sales, and self-operated import/export rights. The company describes ongoing development of parts for newer vehicle types and advanced brake-rotor treatments, indicating product-development activity. However, evidence is insufficient to verify after-sales service performance, financial credibility, or a substantial customer track record. The stated R&D experience is below five years in total, which limits the evidence for deep R&D capability.

Supplier typeThe supplier is described as both a trading company and manufacturer/factory, while another record classifies it as a trading company. A factory is located in Zichuan, Zibo, and its business covers automotive parts, industrial equipment, and related products, indicating a hybrid trading-and-production model.

CertificationsThe supplier states that it holds TS 16949 and ISO 9001 certifications; an additional description references ISO 9002. TS 16949 and ISO 9001 provide explicit evidence of stated automotive quality-management certification holdings.

R&D capabilityThe supplier reports less than five years of total R&D engineer experience, but also states that it develops parts for newer vehicle types and adopts advanced designs and treatments for high-end brake rotors. This supports some product-development activity, although the limited stated R&D experience prevents a stronger conclusion about overall innovation strength.

Production capacityThe supplier reports more than 10 production lines, 41–50 quality-control staff, and stated capacities for brake pads and shoes, brake S-camshafts, vacuum pumps and reducers, brake discs and drums, and steel balls. These details explicitly demonstrate established multi-product production capacity.

Customization capabilityThe supplier covers parts for numerous vehicle brands and states that it develops new parts for newer car and truck types, including specialized brake-rotor designs and surface treatments. This supports product adaptation and development capability, though no specific customer customization workflow or project examples are provided.
