The final determination on in-vehicle system language should be confirmed by the person actually responsible for that step. The supplier should provide VIN-specific photos, videos, diagnostic results, and defect-closure records, while the importer should obtain signoff from the responsible procurement, logistics, after-sales, or compliance personnel. Multiple participants do not mean responsibility is diluted; without signoff, there is no clear stop point when a report verifies only appearance while missing discrepancies in identity, functionality, or documents.
