Why a travel document can tie up your car’s value
When a vehicle enters a country temporarily, customs officials face a practical risk: the visitor could leave the car behind or sell it locally without paying the import duties and taxes that would normally apply. The Carnet de Passages en Douane, often called a carnet, helps manage that risk. It records the vehicle’s temporary entry and gives customs a financial guarantee if the car is not taken back out as required.
The deposit backs a promise
A carnet is issued through an authorized motoring organization, which stands behind the guarantee. To protect that organization from having to pay customs charges on a vehicle that is not re-exported, it may require the traveler to provide security—sometimes a cash deposit, sometimes another form of financial backing. The amount can be substantial because it is linked to the potential import bill, not merely to the cost of processing paperwork.
The money is not a fee for crossing a border. It is collateral: funds held against the possibility that the vehicle will remain in the country and trigger duties. If the traveler follows the temporary-import conditions, the security can be released after the carnet is properly discharged. If the vehicle is not accounted for, customs may seek payment under the guarantee, and the issuing organization may use the traveler’s security to cover its loss.
Border stamps become the paper trail
At each relevant border, customs officials check the carnet and record the vehicle’s entry or exit. Those stamps create evidence that the car followed the permitted route and ultimately left the country. A missing exit record can therefore become more than a paperwork nuisance: it may make it difficult to prove that no import duty is owed. Keeping the document intact and getting the required stamps is part of protecting the deposit.
