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.

These tariff actions are aggregated to the 6-digit level of the Harmonized System (HS) and further classified under the Multilateral Trade Negotiations (MTN) product structure, offering a two-tiered categorization across 22 main categories and 72 sub-categories. The WTO-IMF Tariff Tracker presents these developments at both bilateral and product-specific levels, along with the relevant implementation dates. The data is also aggregated at the GTAP product categories. All datasets can be downloaded, the general Terms of Use apply.

It is important to note that in a context of rapidly evolving trade policy, some tariff actions may be announced without full technical specifications, especially when it comes to product coverage and eligibility. In such cases, the WTO-IMF Tariff Tracker reflects only those provisions for which reliable and verifiable information is available. Where necessary, clearly documented methodological assumptions are used to preserve analytical coherence—without implying any official interpretation by the WTO or the IMF.

Regarding recent bilateral trade deals or arrangements, the WTO-IMF Tariff Tracker includes only those that have been publicly confirmed by both parties and where the terms appear mutually aligned. In cases where an arrangement is only partially documented, the Tracker reflects only those elements that are clearly established.

While every effort is made to ensure the accuracy and timeliness of the information provided, the WTO-IMF Tariff Tracker is intended solely for informational and analytical purposes. Its contents do not constitute legal documentation and should not be construed as an endorsement or legal characterization of any tariff action by the WTO or the IMF. Users are encouraged to consult official sources for authoritative reference.
