Trade barriers are government-induced restrictions on international trade.[1] According to the theory of comparative advantage, trade barriers are detrimental to the world economy and decrease overall economic efficiency.

Most trade barriers work on the same principle: the imposition of some sort of cost (money, time, bureaucracy, quota) on trade that raises the price or availability of the traded products. If two or more nations repeatedly use trade barriers against each other, then a trade war results. Barriers take the form of tariffs (which impose a financial burden on imports) and non-tariff barriers to trade (which uses other overt and covert means to restrict imports and occasionally exports). 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.
