AI-Powered supplier vetting

SummaryShenzhen Yibote Information Technology Co., Ltd. is a China-based limited trading company established in 2017, with six employees and a product scope covering IT networking and optical-fiber communication equipment. It provides 3D software design and multiple forms of customization, including full customization, but reports no new products in the past year. Quality assurance, complaint-handling procedures, supplier-service procedures, and corrective/preventive-action records are documented. However, finished products are checked by packing staff, and raw-material traceability identification is absent. The supplier reports export activity for eight years and derives 90% of total sales from exports, but the information also states that it has no valid import/export license, creating an unresolved export-compliance concern. Financial information confirms records for 2022–2024 but does not provide assessable performance figures. No customer cases or clear certification holdings are provided. The supplier...
