The mechanism: Everyone watches steel tariffs. Almost nobody watches the ore underneath them. Since the Trump administration's April and June 2026 proclamations restructured Section 232 duties on steel, aluminum, and copper — pushing effective steel tariffs toward 50% on covered products and closing derivative-product loopholes — the coverage has focused on finished sheet, plate, and pipe. But the raw-material layer matters more for one company than for anyone else in the sector. Iron ore pellets and related inputs also sit inside a decades-deep lattice of antidumping and countervailing duty orders, continuously renewed via Commerce Department sunset reviews (the most recent batch published in the Federal Register this spring). That's a moat — but only for a company that still makes its own iron.
