The 2016 yearbook issue of Direction of Trade Statistics provides, for about 160 countries, tables with current data (or estimates) on the value of imports from and exports to their most important trading partners. In addition, similar summary tables for the world, industrial countries, and developing countries are included. Reported data are supplemented by estimates whenever such data are not current or are not available in monthly frequency. Country pages include lines for all partner countries that have been reported, estimated, or extrapolated. It is sometimes assumed that corresponding export and import data between partner countries should be consistent. As a result of reporting and processing lags, trade data for a given period are often released before all customs documents for the period have been processed. These data are sometimes not revised, or, if data are revised, errors are nevertheless made in assigning the date on which goods are shipped or received and the late data are assigned to the wrong month, quarter, and/or year.

This paper presents the 2015 yearbook of the Direction of Trade Statistics (DOTS). Quarterly issues of this publication provide, for about 160 countries, tables with current data (or estimates) on the value of imports from and exports to their most important trading partners. In addition, similar summary tables for the world, industrial countries, and developing countries are included. The yearbook provides, for the most recent seven years, detailed trade data by country for approximately 184 countries, the world, and major areas. The information on exports and imports by trading partners that countries report to the Fund varies in terms of frequency and currentness. In order to provide guidance regarding the sources of the figures for individual countries, figures in the country, world, and area pages are shown with symbols to the right of the figure. Country pages include lines for all partner countries that have been reported, estimated, or extrapolated.

This paper discusses that shipments to and from free-trade zones and bonded warehouses, exclusion of military and other confidential items and government goods, value thresholds for customs registration of shipments, returned goods, and other goods missed by customs (or surveys) are examples of coverage differences that can result in inconsistencies. As a result of reporting and processing lags, trade data for a given period are often released before all customs documents for the period have been processed. These data are sometimes not revised, or, if data are revised, errors are nevertheless made in assigning the date on which goods are shipped or received and the late data are assigned to the wrong month, quarter, and/or year. Errors can also be made in assigning a destination to exports and an origin to imports during customs clearances, or in cases when the ultimate destination is changed after the initial consignment during transshipment, the change is not incorporated into published statistics via the release of revised data.
