Import export business is another aspect of general trade. The only difference is that the trading is between an indigenous concern and a foreign company. Normally, these letters have to be written with an understanding of the working of the working company and the cultural milieu (environment) of the people who are responsible for that foreign company. In fact, export business also involves communication at different levels, with licensing authorities, transporters, customers, authorities and others. All correspondence has to be coordinated with speed as the watchword.
