AI-Powered supplier vetting

SummaryThe supplier demonstrates export experience, broad customization and OEM/ODM capability, inventory capacity, valid manufacturing contracts, and ERP-based process management. It holds ISO9001:2015 and CE certifications and reports 90% of sales from exports, with a stated 13 years of exporting experience. However, after-sales governance is weakly documented: no written complaint-handling, corrective/preventive-action, or service-capability assessment procedures were provided. Innovation evidence is limited because no new products were reported in the past year and no SDK is available. Overseas service coverage is also limited, with no overseas warehouse, showroom, agents, branches, or reported service countries. Customer evidence includes OEM service for well-known brands, participation in a Russian exhibition, and a reported repeat-buyer preference of 50%–80%, but no Fortune 500 cooperation.
