The Supreme Court's ruling on Friday leaves tariffs implemented under Section 232 of the Trade Expansion Act of 1962 — which cite national-security concerns — unchanged, keeping in place a range of import duties on products ranging from copper and semiconductors to automobiles and wood products such as cabinetry.

Section 232 tariffs include 50% levies on imports of semi-finished copper products, 25% levies on certain imported semiconductors — including Nvidia's (NVDA) H200 chips — and automobile tariffs, including 25% levies on trucks and 10% levies on buses.
