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.
