The Trump administration’s latest tariffs suggest that uncertainty is becoming a permanent feature of US trade policy. During July, Washington repeatedly changed tariff structures while introducing new investigations, threats, and trade restrictions.
Expanding Tariff Pressure
Several measures were justified through different political and economic concerns. These included forced labour, European digital policies, Canadian commodities, and Brazil’s domestic politics. Despite their different origins, the measures reveal a broader shift toward tariffs as a regular instrument of US policy.
Following the Supreme Court’s rejection of Trump’s original approach under emergency powers, the administration introduced new tariffs. It then turned to Section 301 of the Trade Act, allowing investigations into countries considered unfairly restrictive toward US exports. The first completed investigation targeted goods allegedly connected to forced labour across 59 countries and the European Union.
On 24 July, tariffs were imposed on those economies, establishing minimum rates between 10 and 12 percent. Together, these economies represent nearly all US imports, including countries that had strengthened their own forced-labour enforcement. As a result, the measure extends beyond individual companies and places broader pressure on international trade relationships.
Beyond these measures, other countries have faced additional restrictions. For example, Canadian goods were subjected to tariffs as high as 50 percent, while some Brazilian products received a 25 percent tariff. In Brazil, the measures were widely viewed as politically motivated because they preceded upcoming elections.
Furthermore, additional investigations could expand this pressure. A Section 301 inquiry into excess industrial capacity includes China, India, Japan, and the European Union. Washington also plans to revive investigations into digital protectionism, potentially creating further disputes with European countries and Canada.
The pharmaceutical sector has also become a target, with some tariffs reaching 100 percent. Meanwhile, tensions with China continue despite an existing trade truce. Washington has imposed additional tariffs while Beijing strengthens its ability to restrict critical mineral exports. Consequently, the relationship remains focused on preventing further deterioration rather than achieving substantial progress.
Uncertainty at Home and Abroad
Within the United States, tariff exemptions create another source of ambiguity. They may reduce inflationary pressure, but determining which industries receive preferential treatment makes implementation more complicated. Previous government audits also raised concerns about possible improper influence in tariff exclusion decisions.
At the same time, the new measures are already facing legal challenges, including opposition from 25 US states. Nevertheless, the administration may attempt to preserve high tariff levels by introducing new measures faster than courts can overturn them. This approach could prolong uncertainty even when individual tariffs face legal challenges.
Congress has also contributed to the situation through contradictory responses. Most Americans reportedly oppose tariffs, while some lawmakers seek to restore congressional authority over trade policy. Meanwhile, bipartisan support has emerged for expanding presidential tariff powers against Russia.
This political dynamic makes tariffs difficult to reverse. Their economic costs are widely distributed, while potential benefits remain concentrated among specific industries. Consequently, organized groups have stronger incentives to defend particular tariffs than broader interests have to oppose them.
As businesses adapt to this environment, more companies are learning to operate under uncertainty and negotiate directly for exemptions. This dependence on political decisions could make future administrations less willing to abandon tariffs as a policy tool.
Ultimately, uncertainty itself is becoming part of economic planning. Even if individual tariffs disappear, the broader political incentives supporting their use are likely to remain.
