AI-Powered supplier vetting

SummaryQingdao Zhengya Rubber Industrial Co., Ltd. is a China-based manufacturer established in 2011, with 98 employees and a 11,700 m² manufacturing plant. Its stated product range covers motorcycle, bicycle, wheelbarrow and related tires and inner tubes. Reported production includes 550,000 motorcycle tires and 6,000,000 motorcycle inner tubes annually, supported by two production lines and 6–10 quality-control staff. The supplier reports export activity since establishment, with 90% of sales from exports and markets across South America, Africa, Southeast Asia/Middle East, East Asia and North America. However, no supplier-management-system certifications are reported, and evidence is insufficient to assess after-sales service, customization, or innovation comprehensively. Trade records identify ROAM ELECTRIC LIMITED as an associated buyer and show motorcycle-tire-related transactions, providing limited customer-case evidence.

Supplier typeThe supplier is explicitly identified as a manufacturer and factory, organized as a limited company in China. Its stated business is rubber and tire-product manufacturing, with a dedicated 11,700 m² plant and products including motorcycle, bicycle and wheelbarrow tires and inner tubes.

CertificationsThe supplier-management-system certification field is explicitly reported as NIL. No certification evidence is provided in the available slices, indicating a stated absence of such certifications.

Production capacityProduction capability is supported by the manufacturer status, a 11,700 m² plant, two production lines, 6–10 quality-control staff, and stated annual output of 550,000 motorcycle tires and 6,000,000 motorcycle inner tubes. The supplier also reports one-month lead times in both peak and off-peak periods, although the slices do not independently verify these capacities.

Client casesTwo trade-record slices identify ROAM ELECTRIC LIMITED as an associated buyer and show motorcycle-tire-related products, including components for electric motorcycles and 90/90-17 motorcycle tires. These records provide evidence of at least one buyer relationship and relevant product transactions, but they do not establish customer satisfaction, repeat orders or the broader scale of the customer base.
