A 'trade barrier' is a general term that describes any government policy or regulation that restricts
international trade. The barriers can take many forms, including:
★
Import duties
★
Import licenses
★
Export licenses
★
Import quotas
★
Tariffs
★
Subsidies
★
Non-tariff barriers to trade
★
Voluntary Export Restraints

Most trade barriers work on the same principle: the imposition of some sort of
cost on trade that raises the price of the traded
products. If two or more nations repeatedly use trade barriers against each other, then a
trade war results.
Economists generally agree that trade barriers are detrimental and decrease overall
economic efficiency, this can be explained by the
theory of comparative advantage. In theory,
free trade involves the removal of all such barriers, except perhaps those considered necessary for health or national security. In practice, however, even those countries promoting free trade heavily subsidize certain industries, such as
agriculture and
steel. Examples of free trade areas are:
North American Free Trade Agreement (NAFTA),
South Asia Free Trade Agreement(SAFTA),
European Free Trade Association,
European Union (EU),
Union of South American Nations.
Other trade barriers include differences in culture, customs, traditions, laws, language and currency.
