Trade barrier

Trade barriers are government-induced restrictions on international trade. The barriers can take many forms, including the following:

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.

Trade barriers are often criticized for the effect they have on the developing world. Because rich-country players call most of the shots and set trade policies, goods such as crops that developing countries are best at producing still face high barriers. Trade barriers such as taxes on food imports or subsidies for farmers in developed economies lead to overproduction and dumping on world markets, thus lowering prices and hurting poor-country farmers. Tariffs also tend to be anti-poor, with low rates for raw commodities and high rates for labor-intensive processed goods. The Commitment to Development Index measures the effect that rich country trade policies actually have on the developing world.

Trade barriers are mostly a combination of conformity and per-shipment requirements requested abroad, and weak inspection or certification procedures at home. The impact of trade barriers on companies and countries is highly uneven. One particular study showed that small firms are most affected (over 50%).

Another negative aspect of trade barriers is that they result in a limited choice of products and would therefore force customers to pay higher prices and accept inferior quality.

Trade barriers obstruct free trade. Before exporting or importing to other countries, firstly, they must be aware of restrictions that the government imposes on the trade. Subsequently they need to make sure that they are not violating the restrictions by checking related regulations on tax or duty, and finally they probably need a license in order to ensure a smooth export or import business and reduce the risk of penalty or violation. Sometimes the situation becomes even more complicated with the changing of policy and restrictions of a country.
