The process of exchanging goods and services is generally being referred to as trading. There are two main types of trade. The simplest one is the bilateral trade, which takes place between two parties. The other type of trade is the multilateral one, which, of course, is the one to involve more than two parties. No matter the type of it, trade can be done within the same country or between different countries. The latter type is called international trade, as the exchange of goods and services or both takes place between an exporter and an importer, meaning that the two or more partners involved are from different countries.

Nevertheless, there are a number of elements to prevent things from going smoothly. People use to classify these barriers as being tariff barriers, non-tariff ones and voluntary constraints. However, what do these words mean? Many of you may not understand the real meaning of this classification.

Well, we shall start with the voluntary constraints, which refer to the voluntary stopping of incoming products by a certain country. Because of them, a country has the power to stop the imports coming frequently into the country and limiting the competition with the foreign goods with the local industries.

The non-tariff barriers are set by the country on imports by restricting quantity of importing. This means that a particular quantity is defined for the importing products, thus making the price level of the imported goods high. Due to this fact, the supply of foreign goods becomes limited. On the other hand, the tariff barriers are being put on imports in the form of duties, tax and quotas. The result of these barriers is the reducing of the imports. The price level of imported products rises and the demand for them decreases.

There main advantage of setting Tariff and non-Tariff barriers is that the country earns foreign exchange and that the local industry of the country is protected by the foreign competitive industries. Another key element is that the consumer will buy more local products, if the imported goods are getting fewer and fewer. The country will gain more revenue from the currency that stays in the country. These are all reasons for governments to keep the trade barriers, don�t you think?

So, you should decide going into the international trade business, but, with these barriers considered! Good luck!
