Market access
World trade in 2010: Introduction
World trade recorded its largest ever annual increase in 2010 as merchandise exports surged 14.5 per cent, buoyed by a 3.6 per cent recovery in global output as measured by gross domestic product (GDP) . Both trade and output grew faster in developing economies than in developed ones. Exports in volume terms (i.e. in real terms, accounting for changes in prices and exchange rates) were up 13 per cent in developed economies while the increase for developing economies was nearly 17 per cent. The difference between trade of developed and developing economies was even greater on the import side, where developed economies’ imports rose by 11 per cent compared with 18 per cent in the rest of the world.
Introduction
The World Tariff Profiles is a joint publication of the WTO, ITC and UNCTAD devoted to market access for goods. This statistical yearbook contains a comprehensive compilation of the main tariff parameters for each of the 161 WTO members plus other countries and customs territories where data is available. Each tariff profile presents information on tariffs imposed by each economy on its imports complemented with an analysis of the market access conditions it faces in its major export markets.
Nota general y abreviaturas
Las estadísticas relativas a los aranceles aplicados y las importaciones se calculan utilizando datos basados en la nomenclatura del SA adoptada por el país para el año de referencia. Para las estadísticas relativas a los aranceles consolidados, los cálculos se basan en la Lista de concesiones aprobada del Miembro de la OMC. En las anteriores ediciones de la publicación Perfiles arancelarios en el mundo, cada Lista se basaba en la versión del SA que el Miembro utilizaba en el momento de su adhesión a la OMC. A partir de la edición de 2010, las estadísticas de los aranceles consolidados se basan en la lista de concesiones aprobada de cada Miembro conforme a la versión más reciente del SA. Esto puede tener algunas consecuencias en la serie histórica de diversos indicadores de aranceles consolidados que se ven afectados por el uso de una nomenclatura diferente. Aunque los compromisos del Miembro no hayan cambiado como resultado de la transposición, algunas estadísticas agregadas pueden verse afectadas como consecuencia del cambio a otra versión del SA.
Acknowledgements
Acknowledgements are due to all the data providers, mostly national administrations or WTO delegations who have made this information available including through notifications presented as a special topic. In a number of cases, data has been made available on national websites or through regional organizations. Given the vast amount of statistical data and metadata that needed to be processed, and because this information is not available in one single organization, this publication was only possible as a joint effort of the WTO, ITC, and UNCTAD. Each of the three organizations has a proven track record and comparative strengths in the field of tariff analysis.
