ABSTRACT

As per the international conventions, Nepal, which is a landlocked country, is entitled to use the facility of the nearest seaport(s) of India to import goods from third countries and to get duty-free transit facility of such goods through India. Movement of such third country cargo often poses an inherent security risk for India and the management and monitoring of such cargo is vital to the economic and national well-being of India. On the other hand, the need for expediting the Customs formalities and clearance of such cargo is of paramount importance, keeping in view the bilateral ties between India and Nepal. icNIMS: Indian Customs Nepal Import Management System is an online and web-based system to handle issuance of Letters of Credit by banks, filing of CTD by the importers of third-country goods based in Nepal, handling the Customs clearance of imported third country goods and generation of statistical reports. By successfully implementing icNIMS, a substantial knowledge has been acquired regarding the implementation of a dynamic web based database system using open source technologies. This knowledge will be useful in the future for creating any type of web based application with backend database.
