Since the beginning of the second Trump Administration on January 20, 2025, President Donald J. Trump has used various trade authorities to impose tariffs. Following the Supreme Court's ruling on February 20, 2026, invalidating the Trump Administration's use of the International Emergency Economic Powers Act (IEEPA) to impose certain tariffs, President Trump has used a combination of other trade authorities to impose tariffs.1 President Trump announced a global 10% tariff rate using Section 122 authorities shortly after the Supreme Court's IEEPA decision.2 Section 122 authorizes the President to levy duties for no more than 150 days barring legislation from Congress authorizing an extension.3
With the expiration of the Section 122 tariffs on July 24, 2026, the President imposed additional duties using Section 301 of the Trade Act of 1974 and continued to use Section 232 of the Trade Expansion Act of 1962 to impose duties throughout 2026. Unlike IEEPA, both authorities require an investigation be completed before imposing additional duties. In the case of Section 232, that investigation is undertaken by the Bureau of Industry and Security (BIS) in the Department of Commerce. In the case of Section 301, that investigation is undertaken by the U.S. Trade Representative (USTR).
On July 23, 2026, President Trump imposed tariff rates of 10% or 12.5% on 60 economies resulting from USTR's final determination of its Section 301 investigation into whether the relevant countries had banned—and effectively enforced those bans—on imports made with forced labor.4 Other Section 301 investigations, including one into structural excess capacity and production in manufacturing sectors, are ongoing.5 BIS is also in the process of conducting other Section 232 investigations to determine whether to levy further duties on specific goods for national security purposes.6
Since the February 20, 2026, Supreme Court decision, the President has cited authorities from four laws to impose higher tariff rates:
This fact sheet provides a summary table of the tariff actions taken during the second Trump Administration that are in effect as of September 30, 2026, or are currently under active investigation. The table includes a brief description of the action, the most recent non-amended Federal Register notice related to the action, the countries impacted by the action, and the latest tariff rate imposed or status of the investigation. Actions are organized under the authorities used and in alphabetical order by their descriptions. U.S. negotiations with trading partners are ongoing, including the statutorily required joint review of the U.S.-Canada-Mexico Agreement (USMCA). The summary table may be periodically updated to reflect outcomes from USMCA negotiations and other talks with partner nations, as well as implementations of announced framework agreements.
