Trump Amends Steel, Aluminum, Copper Tariffs with New Proclamation

On a recent Monday, U.S. President Donald Trump announced significant changes to tariffs on steel, aluminum, and copper imports. These adjustments focus on supporting the agricultural sector while maintaining a strong stance on national security measures.
New Tariff Modifications
The executive order details a reduction in tariffs on certain agricultural equipment, including combines and harvesters. The tariffs have been lowered from 25% to 15% for these items. The updated order also introduces a broader category of industrial equipment.
Expansion of Equipment Categories
- Newly included under the 15% tariff are mobile industrial equipment, such as bulldozers and forklifts.
- These changes only apply to equipment imported from countries with trade agreements with the U.S.
Moreover, countries using at least 85% from melted steel or aluminum could qualify for a reduced duty rate of 10%. This initiative aims to encourage foreign companies to utilize U.S. metals.
Temporary Provisions Until 2027
These tariff adjustments are temporary and will remain in effect until the end of 2027. Trump believes this modification accurately reflects the importance of these products in the U.S. economy.
Background on Tariffs
The current tariffs on steel, aluminum, and copper were first established during Trump’s initial term in 2018. These were enacted under Section 232 of the Trade Expansion Act of 1962, which permits tariffs on imports perceived as threats to national security. In April 2025, Trump renewed these tariffs, further increasing rates in June 2025 and again in April 2026.
Recent Tariff Rates
- June 2025 saw tariffs on steel and aluminum raised to 50% from 25%.
- April 2026 established a flat 50% rate for goods mainly composed of aluminum, steel, or copper.
- Derivative products made significantly from these metals are subject to a 25% tariff.
Barry Appleton, a professor of law, suggests that these tariff changes may be politically motivated. He observes that farm bankruptcies are increasing, and agricultural sentiment is waning. Republican senators have expressed concerns about potential losses in key agricultural states during the upcoming midterm elections. According to Appleton, this proclamation may be an effort by the White House to appease voters in the farming sector.
