AI-Powered supplier vetting

SummaryLaibisheng Bearing (Shandong) Co., Ltd. is identified as a Chinese manufacturer/factory established in 2008, offering multiple bearing categories. It reports nine production lines, ISO 9001 certification, extensive stated production quantities, and exports to multiple global regions. Its export-sales share is stated as 71%–90%, indicating substantial international market exposure. However, the available audit record expired on 2024-11-05, and several important capabilities—including after-sales support, R&D depth, OEM/ODM, customization, traceability, and sustainability systems—are marked unknown. The supplier’s quality-control and R&D staffing are each reported as fewer than five personnel, which limits evidence of organizational depth. Customer-market evidence exists through stated sales to Britain, America, Japan, Italy, and Southeast Asia, but no specific customer names or verified case details are provided.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and describes itself as engaged in bearing research, development, manufacturing, and sales. It was founded in March 2008, supporting an established operating history.

CertificationsThe supplier reports ISO 9001 certification. An SGS audit was conducted, but the recorded report validity ended on 2024-11-05; the provided information does not establish current certification or audit validity beyond that date.

Production capacityThe supplier reports nine production lines and substantial stated output across auto, roller, ball, needle bearings, and bearing housings. Its broad product range and exports to multiple regions support production experience, although the annual productivity fields in one slice are incomplete.

Client casesThe supplier reports exports to South America, Eastern Europe, the Middle East, North America, Southeast Asia, Eastern Asia, Oceania, Western Europe, and Africa, and specifically states that products are sold in Britain, America, Japan, Italy, and Southeast Asia. No named customers, order examples, or independently verified case studies are provided.
