US Section 301 tariffs target 60 trade partners after Supreme Court setback

US Section 301

US Section 301 tariffs are moving back to the center of US trade policy. The administration plans new import taxes on 60 major trade partners. US Section 301 tariffs aim to replace emergency tariffs the Supreme Court invalidated.

The US Trade Representative has opened investigations into 59 countries and the EU. Officials argue partners fail to block goods tied to forced labor in third countries. Therefore, the US wants a new legal path to impose broad tariffs by late July.

Why the US is pivoting from emergency tariffs to Section 301

Section 301 gives the US a well-used tool to target “unfair” foreign practices. The plan would expand that tool across dozens of jurisdictions at once. However, that scale could invite legal challenges and political pushback.

The administration already imposed a temporary 10pc tariff under Section 122. That measure expires on 24 July under the current timeline. As a result, the USTR wants Section 301 outcomes ready by that deadline.

What it means for metals, autos, and industrial supply chains

The Section 301 process does not change existing tariffs on steel, aluminium, cars, or auto parts. However, broad new duties can still raise landed costs for components, machinery, and inputs. That pressure can tighten working capital and push buyers toward regional sourcing.

US Section 301 tariffs also add compliance risk for importers and distributors. Firms may need stronger traceability on labor exposure across multi-tier supply chains. Meanwhile, refund uncertainty from earlier tariff disputes can keep companies cautious on spot purchases.

The Metalnomist Commentary

This strategy looks like legal re-engineering, not a narrow trade remedy. However, the forced-labor framing will test how fast partners can prove compliance at scale. The biggest near-term cost may come from uncertainty, not the final tariff rate.
