AI-Powered supplier vetting

SummaryBofa Import and Export Co., Ltd. is identified as a Hong Kong limited company with trading-company and manufacturer/factory classifications, offering bearings. Its stated factory location is in Linqing City, Shandong Province, China, while the registered company address is in Hong Kong. The supplier reports TS 16949 and ISO 9001 management-system certifications and has an external audit record from TÜV Rheinland, although the audit result is recorded as “0” without an interpretation. Production information states annual output of 300,000 ball bearings and 200,000 roller bearings, with off-peak lead time within 15 working days and 21–30 quality-control staff reported in one slice. Customization from samples is available, but the supplier reports no new products in the past year, no ODM service, and no available SDK. Financial records are indicated for 2022–2024, but no financial performance details are provided. Evidence of after-sales capability and customer cases is absent.

CertificationsThe supplier reports TS 16949 and ISO 9001 management-system certifications. A TÜV Rheinland audit record is also listed with a report period from 2025-09-23 to 2026-09-22, but the audit result is recorded as “0” without a stated meaning, so the audit outcome cannot be positively assessed from the provided data.

R&D capabilityThe supplier reports one R&D engineer and total R&D engineer experience of 6–10 years, but also reports no new products in the past year, no ODM service, and no available SDK. These explicit limitations indicate weak demonstrated recent innovation and development breadth.

Production capacityThe supplier provides annual output information of 300,000 ball bearings and 200,000 roller bearings, reports off-peak lead time within 15 working days, and lists 21–30 quality-control staff in one record. It also identifies a factory location and bearing as its primary product, providing positive evidence of production capability, although the conflicting report of only one total employee limits confidence in the scale data.

Customization capabilityThe supplier explicitly offers customization from samples and states that it can customize various large non-standard products according to customer demands. However, it does not provide ODM services, so the evidence supports sample-based and non-standard customization rather than full product-development outsourcing.
