The execution of an international trade operation implies the accomplishment of a series of commercial, transport and regulatory requirements. Any inefficience in such activities can generate unnecessary delays and costs to the transboundary movement of goods, that reduce in turn the competitiveness of economic operators. To date, the main inefficiences in the import/export processes concern: time for preparation of transport documents, fulfilment of administrative and regulatory requirements related to the execution of international trade transactions, unclear border procedures and excessive controls. To help to detect and address these probles, UNESCAP, in cooperation with UNECE and UnNEXT, has developed, since 2009, a Business process analisys guide to simplify trade procedures.
