For verifying a supplier, Mexican importers can use an item-by-item sign-off approach: purchasing confirms the company registration and export business scope, technical staff confirm previous shipments and document samples, and the delivery side confirms the physical vehicles, stock and delivery plan. Check the company registration, export business records and two redacted sets of historical documents, and match the stock vehicles to VINs over a live video call. The person in charge logs the company registration and export business scope first, then verifies the previous shipments and document samples. If the physical vehicles, stock or delivery plan change, the earlier conclusion no longer stands.
