Market access
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 164 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 de agradecimiento
Queremos dar las gracias a todas las instituciones que han suministrado datos incluyendo las notificationes en los cuadros del tema especial, sobre todo a las administraciones nacionales o las delegaciones ante la OMC que han facilitado toda esta información. En algunos casos, los datos se han publicado en sitios Web nacionales o a través de organizaciones regionales. Dada la enorme cantidad de datos y metadatos estadísticos que ha sido necesario procesar, y debido a que esa información no se encuentra en una única organización, la presente publicación sólo ha sido posible como esfuerzo conjunto de la OMC, el ITC y la UNCTAD. Cada una de estas tres organizaciones posee una reconocida experiencia en actividades de análisis arancelario y una destacada pericia en la materia.
