1. International trade takes place basically due to geographical specialisation. Every country specialises in the production of goods and services in which it has a specific advantage. For example, India has specific advantage in the production of jute and tea. Therefore, India exports these commodities to U.K. India imports steel from U.K. which U.K. can produce at a lower cost than India.
2. International competition: Producers from many countries complete with another to sell their products. Therefore, there is intense competition in international trade. Here the quality, design, packing, price, advertisement, etc., all play a significant role in deciding the winner in the market.
3. Separation of sellers from buyers: In international trade sellers and buyers belong to different countries. They may have no chance of ever meeting one another. Therefore, they have to depend upon middlemen for transactions.
4. Long chain of middlemen: The procedure of international trade is very long and complex. It is very difficult for buyers and sellers to perform all the formalities themselves. They require the services of expert middlemen such as, indent houses, forwarding agents, clearing agents, foreign exchange banks, etc.
5. Mutually acceptable currency: The currencies of importing and exporting countries generally are different. Therefore, it is necessary to find out a mutually acceptable currency. Generally, dollar and pound sterling are selected. These currencies are known as hard currencies because they are acceptable all over the world.
