Customs will undertake a stringent inspection of the goods; the effective operation of the TIR procedure depends on this inspection, as explained in Article 19 of TIR Convention. Customs will check that the TIR Carnet is valid and will also verify the TIR Carnet details and any attached documents. In addition, Customs will check the vehicle and the load compartment(s), and verify the Road Vehicle Approval Certificate, which must be valid for the entire TIR operation, that is until the goods arrive at the office of destination. Once the goods are loaded Customs will seal the load compartment, complete and stamp the TIR Carnet as appropriate, tear off the first white voucher (volet 1) and return the TIR Carnet to the driver. The white voucher will be registered by Customs, awaiting the return of the certificate of termination from the green voucher (volet 2) from the Customs office of exit or destination. Depending on national arrangements, the white voucher (volet 1) may be filed either locally at the office of departure or at a central office.
