The supplier supports customization from samples, designs, and minor modifications, but does not provide 3D software design services and has no available SDK. No supplier management-system certification is reported. Production controls show a stated gap in continuous quantity reconciliation and finished-product inspections are guided by instructions without written records. Financial-capacity indicators are reported for 2023–2025, but the slices do not establish financial strength. Audit information identifies TÜV Rheinland and a report validity period, but no favorable audit outcome is demonstrated.
