AI-Powered supplier vetting

SummaryZhejiang Sanrock Supply Management Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory, offering mining machinery and related mechanical and electronic equipment. It reports strong export orientation, with 90% of total sales from exports, self-operated import/export rights, and five years of export experience. Customization is available across sample-based, design-based, full, minor, and flexible formats. However, the supplier is not identified as a professional technical supplier and does not provide 3D software design services. Evidence is insufficient for certification holding, financial credibility, production capacity, and customer cases. Service procedures for supplier approval, corrective actions, and complaint handling exist but lack written records; inventory, overseas warehouse, and overseas showroom capabilities are explicitly absent.

Supplier typeThe supplier is a limited company in Zhejiang, China, classified as both a trading company and manufacturer/factory. Its stated scope covers mining machinery, mechanical equipment, electronic products, supply-chain services, warehousing, and consulting activities.

After-Sales capabilityThe supplier has procedures for handling customer complaints and corrective/preventive actions, but no written records are available. It also explicitly lacks in-stock service capacity, overseas warehouse capability, and overseas showroom capability, while the effectiveness of after-sales execution is not demonstrated.

R&D capabilityThe supplier is explicitly not a professional technical supplier and does not provide 3D software design services. Although it offers several customization formats, the records do not establish research, development, or advanced innovation capability.

This provides direct evidence of broad customization service capability, although it does not establish 3D design support.
