Trump Slashes Metal Tariffs To 15% For Power Grid Transformers Through 2027

The Trump administration has cut tariffs on large power grid transformers to 15%, down from a previous rate based on steel and aluminum content. The change is a temporary measure lasting through 2027. It applies to large transformers and other metal-heavy equipment used to expand power grids across the country.

The Trump administration has temporarily slashed transformer tariffs to 15%, simplifying import costs through 2027.

Before this change, importers had to calculate tariffs based on how much steel or aluminum was inside each product. That system was complex and created compliance headaches for businesses. The new flat 15% rate applies to the full value of qualifying products, making the process simpler.

The broader tariff structure has also changed. Products that are 15% or more metal by weight now face a flat 25% tariff on their full price. Items below that 15% metal threshold are exempt from the sectoral tariff altogether. Primary aluminum, steel articles, and certain copper still face a 50% tariff.

Not all products are treated equally under the new rules. Cosmetics, food, furniture, and household chemicals are exempt. Certain engines and parts also won’t face the sectoral tariff. Products made entirely with U.S.-origin metals qualify for reduced rates.

The transformer industry’s expected to benefit from the lower import costs. But home appliance makers aren’t as lucky. Products like washing machines and refrigerators face higher burdens under the new structure. Samsung’s been analyzing how the changes will affect its business, though its U.S. factories may help soften the blow.

The administration says the tariff policy is meant to boost domestic metal production. Steel capacity utilization has already risen from 72.3% in 2017 to 77.2%. Domestic aluminum capacity utilization climbed from 39% to 50.4% over the same period. The goal is to hit 80% sustained capacity utilization. These efforts come as the renewable energy sector continues to face supply chain vulnerabilities, with 90% of solar components and 65% of wind components still imported from China.

The legal authority for these changes comes from Section 232 of trade law, which deals with national security. The proclamation also modifies earlier executive actions, including Proclamations 9704, 9705, and 10962. The United Kingdom faces rates between 15% and 25% depending on where its metals were originally smelted or cast.
