The World Bank — in collaboration with the United Nations Conference on Trade and Development (UNCTAD) and in consultation with organizations such as International Trade Center, United Nations Statistical Division (UNSD) and the World Trade Organization (WTO) — developed the World Integrated Trade Solution (WITS). This software allows users to access and retrieve information on trade and tariffs. Below is list of international organizations that compile this data: The UNSD Commodity Trade (UN Comtrade) (UN Comtrade) database contains merchandise trade exports and imports by detailed commodity and partner country data. Values are recorded in U,S. dollars, along with a variety of quantity measures. The database includes information on more than 170 countries, and features statistics that have been reported to the United Nations since 1962. These statistics and data continue to be recorded according to internationally recognized trade and tariff classifications. The UNCTAD Trade Analysis Information System (TRAINS) contains information on imports, tariffs, para-tariffs and non-tariff measures. The data on tariffs, para-tariffs and non-tariff measures are available at the most detailed commodity level of the national tariffs (i.e., at the tariff line level). The data are recorded according to three internationally recognized trade and tariff classifications The WTO's Integrated Data Base (IDB) contains imports by commodity and partner countries and Most Favored Nation (MFN) applied and, where available, data on preferential tariffs at the most detailed commodity level of the national tariffs. The Consolidated Tariff Schedule Data Base (CTS) contains WTO-bound tariffs, Initial Negotiating Rights and other indicators. The CTS reflects the concessions made by countries during goods negotiations (e.g., the Uruguay Round of Multilateral Trade Negotiations). The IDB and CTS are practical working tools and there are no implications as to the legal status of the information contained therein. The World Bank and the Center for International Business, Tuck School of Business at Dartmouth College Global Preferential Trade Agreements Database provide information on preferential trade agreements (PTAs) around the world, including agreements that have not yet been notified to the World Trade Organization. This resource helps trade policy makers, research analysts, the academia, trade professionals and other individuals better understand and navigate the world of PTAs.
