US President Donald Trump has signed a proclamation reducing tariffs on steel, aluminium and copper derivatives, cutting duties on certain industrial equipment to 15% until 2027 to accelerate industrial expansion.

WASHINGTON: US President Donald Trump has signed a new trade proclamation adjusting tariffs on imports of steel, aluminium and copper, reducing duties on derivatives made from these metals in a move aimed at boosting industrial expansion, simplifying compliance procedures and preventing manipulation of import values.

The White House confirmed that the United States will maintain a 50% import duty on steel, aluminium and copper imports under Section 232 of the Trade Act of 1974, applied to prices paid by American customers. However, significant reductions have been introduced for specific categories of goods.

Tariffs on certain industrial equipment and electrical grid components that use substantial quantities of these metals will be reduced from 50% to 15% until 2027. The White House said the move is designed to accelerate the pace of industrial expansion across the country, easing the cost burden on sectors that depend heavily on these materials.

A further adjustment eliminates the previous 50% tariff on derivative products made from steel, aluminium and copper where the metal content of the product is less than 15% by weight. The change is intended to prevent abuse of the tariff system and reduce unnecessary cost pressures on manufacturers working with lower metal content goods.

The adjustments represent a calibrated shift in the administration’s trade posture, balancing the protection of domestic metal producers with the need to support downstream industries that rely on these materials as inputs.

The proclamation is expected to be welcomed by manufacturers and industrial operators who had raised concerns about the impact of blanket tariffs on their supply chains and production costs.
