Commercial exchange is that economic transaction that has developed since the beginning of centuries, almost since the appearance of man on the face of the earth. Currently, these exchanges have had a great development, since thanks to globalization transactions can be carried out from anywhere on the planet, something that in years ago was not even thought. It is necessary to consider that the sums of the possibilities that a region can offer and the combination of elements produced make the perfect climate for negotiations. Many of the products and services that are so necessary today for the day to day could only be achieved thanks to world free trade.
It was from the middle of the 20th century that the commercial exchange began to grow, but since the 1990s, countries began to open up to the world and thus their economies. So at present almost no country remains unaware of what happens outside its borders.
It is necessary to refer to other forms of exchange that are not necessarily economic. However, everyday use and the different scopes obtained make this process clear and relevant in our lives.
Commercial exchange is also done between countries of the world and is known as international trade, which consists of buying and selling goods, services or products and for which a customs duty must be canceled, either for export and import, according to the case.
To protect the economies of their countries, the leaders have decided to eliminate some customs taxes and instead have agreed common tariffs, in order to allow the free movement and circulation of goods and products, to maintain economic relations with their direct competition.
