About WITS


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.

There is no charge to use the WITS software.

However, databases may have different contractual arrangements, therefore access rights and fees may vary depending on the user status:

  • Access to UN Comtrade data is free for users with UN prescribed limits. Premium services can be purchased through UNSD;
  • Access to UNCTAD TRAINS is free and accessible for all users and
  • All users have free access to WTO IDB and CTS tariff data at the tariff-line level. WTO 6 digit data are generally available. Access to tariffline imports data is restricted to certain users based on WTO guidelines.
WITS is both:
  • a gateway to merchandise trade and protection statistics through the databases listed above, allowing for retrieving, extracting and even exporting data.
  • an analytical and simulation tool to estimate consequences of changes in tariff.

WITS is continuously undergoing improvements. New features are regularly added or updated to enhance user experience. If you have any suggestions, please send your coments to wits@worldbank.org or post your suggestions/feedback in our user forum.
