President Donald Trump signed a presidential proclamation on Monday to partially revise additional tariffs on aluminum, steel, and copper products [1].
The move aims to lower costs for U.S. farmers and manufacturers who have faced surging prices for raw materials and fertilizer following the effective blockade of the Strait of Hormuz [1], [5].
Under the new order, additional tariffs on agricultural and construction machinery will drop from 25% to 15% [1]. The administration also established special exemptions for imports from specific countries, including Japan, South Korea, and members of the European Union, removing the additional tariffs for these partners [1], [2].
Existing additional tariffs on aluminum, steel, and copper remain at 50% for most imports [5]. However, the proclamation introduces a reduced rate of 10% for metals if the domestic casting ratio is 85% or higher [1].
The revised tariff schedule is set to take effect on June 8 [1]. These measures are designed as a temporary relief system and will remain in place until the end of 2027 [1], [5].
White House officials said the policy is intended to support domestic industry by curbing the cost burden on essential sectors during a period of global supply chain instability [1], [5].
“Additional tariffs on agricultural and construction machinery will drop from 25% to 15%”
This policy shift represents a strategic pivot to protect the U.S. domestic economy from external geopolitical shocks. By lowering costs for the agricultural and construction sectors and granting exemptions to key allies, the U.S. is attempting to mitigate the inflationary pressure caused by Middle Eastern instability while maintaining a general protectionist stance on raw metals.
