An in-depth understanding of trading processes is required in order to identify areas that create bottlenecks in trade and to take measures to remove such bottlenecks. Towards this end, this study examines the trading procedures and processes for two export and two import products of Sri Lanka. The study involves mapping the processes involved in the export of tea to Japan and tyres to India, and the processes involved in the import of motor vehicles from Japan and textiles from India, through a business process analysis. This study has attempted to list all the required documents and all procedural requirements from the point of order to shipment, and to also estimate the costs of trade for the selected products.
