It provides OEM services for well-known brands and supports multiple forms of customization. Export activity is substantial, with 90% of total sales reportedly from exports and 13 years of export experience. However, the supplier has only one employee, one cooperative supplier, no available SDK, and no overseas agents, branches, warehouses, showrooms, or offline trade-show participation. Audit information identifies TUV Rheinland and a report validity period from February 21, 2025 to February 20, 2026, but the audit evaluation result is recorded as 0 without an interpretation. Quality assurance status and manufacturing-contract status are unknown, while complaint-handling and corrective-action procedures exist without written records.
