Tariff Actions Database

The WTO-IMF Tariff Tracker is a joint transparency initiative developed by the World Trade Organization (WTO) and the International Monetary Fund (IMF) to monitor and visualize changes in effectively applied import duties. Drawing on data from the WTO’s Integrated Database and WTO’s Analytical Database, the tracker records tariff actions at the tariff line level, covering Most Favoured Nation (MFN) applied rates, preferential tariff rates granted under preferential duty arrangements, and any subsequent modifications—whether increases, reductions, or substitutions.

Key Data Components: Market information (reporter and parter), initial rates, revised rate
