CEVAP:

Tariffs have been the mostly used trade restrictions ever since the beginning of international trade among the countries. A tariff is a tax or a duty that is levied on a traded commodity while it gets through a national border. Tariffs can be implemented both on the imports and exports. Since import tariffs have a broader implementation than the export tariffs all over the world, most discussions are on them and their economic effects. Import tariffs are widely used by the industrialized countries on the imports coming from the developing countries while the export tariffs are implemented by the developing countries on their labor-intensive exports.
