Cultural Tip
In most Latin American countries and Spain, customs forms are handed out on the plane or available at the checkpoint. Some airports now use electronic tablets, but the wording of the question remains the same. Remember that the form usually asks for the value of goods, your destination, and whether you are carrying restricted items. Being prepared with the correct paperwork can speed up the inspection process.
