The supplier supports extensive customization and ODM services, has introduced new products within the past year, and reports OEM service for well-known brands. However, it reports no supplier-management-system certifications, fewer than five quality-control staff, no valid manufacturing-capacity contract with related subcontractors, no overseas agents, branches, warehouses, or showrooms, and no offline trade-show participation.
