What are Tariff Barriers?

Tariff barriers are duties imposed on goods which effectively create an obstacle to trade, although this is not necessarily the purpose of putting tariffs in place. Tariff barriers are also sometimes known as import restraints, because they limit the amount of goods which can be imported into a country. Many organizations which promote trade are concerned about both tariff and non-tariff barriers to free trade, and a number of nations have agreed to radically reduce their trade barriers to promote the exchange of goods across their borders.
