The World Integrated Trade Solution (WITS) is software developed by the World Bank, in close collaboration with the United Nations Conference on Trade and Development (UNCTAD).

WITS gives you access to the major trade and tariffs data compilations :

• The COMTRADE database maintained by the UNSD;
• The TRAINS maintained by the UNCTAD;
• The IDB and CTS databases maintained by the WTO.

WITS is a data consultation and extraction software with simulation capabilities.

WITS is a free software. However, access to databases themselves can be fee-charging or limited depending on your status. (see this page for more information).
