AI-Powered supplier vetting

SummaryXinzhou Bearing Industry Inc. is a China-based limited trading company established in 2012, operating from Shanghai with a stated factory location in Fengxian District. It focuses on ceramic, hybrid, stainless steel, thin-section, angular-contact, full-ceramic, slew-ring, and deep-groove bearings. The supplier reports four production lines, fewer than five quality-control staff, a 196.0 m² manufacturing plant, and lead times within 15 workdays in both peak and off-peak seasons. Export activity is significant, with 90% of sales reportedly from exports and primary markets in Europe and North America. The company claims expertise in specialized and custom bearing applications, but no supplier-management-system certifications are listed. Evidence is insufficient to verify after-sales service, financial credibility, innovation performance, or customer cases.

Supplier typeThe supplier is explicitly identified as a trading company and limited company, with its business industry classified as wholesale and retail. Its profile therefore indicates a trading-oriented business structure rather than a clearly documented manufacturer-only structure.

CertificationsThe supplier-management-system certification field is explicitly recorded as NIL. No certification evidence is provided in the available information, indicating a documented deficiency for this field.

Production capacityThe supplier reports four production lines, a 196.0 m² manufacturing plant, fewer than five quality-control staff, and lead times within 15 workdays during both peak and off-peak periods. These data demonstrate stated production operations and delivery capacity, but the small facility and limited quality-control staffing suggest that scale and quality-system depth are not strongly evidenced.

Customization capabilityThe supplier explicitly invites custom bearing requirements and states that it can apply its expertise to demanding bearing applications. This is direct evidence of claimed customization support, although the slices do not specify customization scope, engineering workflow, tooling capability, or completed examples.
