Since early 2025, U.S. trade policy has undergone significant recalibration with respect to steel, aluminum, and critical magnet components. Presidential proclamations have raised Section 232 tariffs on steel and aluminum from 25 percent to 50 percent, effective June 4, 2025, reflecting a strategic effort to bolster domestic industries and address perceived national security vulnerabilities. This action ended most product exclusion processes and applied the increased rates to both raw materials and derivative articles, intensifying cost pressures for manufacturers reliant on imported metal content.

In parallel, the administration clarified that total duties on Chinese imports of key magnet materials now exceed 145 percent when accounting for combined Section 301 tariffs, fentanyl-related duties, and universal tariff measures, directly impacting the sourcing of soft magnetic composites and rare earth magnetic components alike. These elevated rates have prompted supply chain realignments and accelerated conversations around domestic production of powder core feedstocks. In addition, magnets assembled with steel or aluminum housings are subject to the higher 50 percent levy, compounding the burden on imported power inductors, EMI filters, and transformer cores.

Looking ahead, a forthcoming tariff set to impose a 25 percent duty on permanent magnet imports from China beginning January 1, 2026, underscores the continuing emphasis on onshoring strategic material production. Given these cumulative trade measures, industry participants are evaluating alternative sourcing strategies, expanding local processing capacities, and exploring substitute alloys to mitigate the cost impact and preserve competitive positioning.
