60 Partners Hit with Section 301 Tariffs After Supreme Court Rebuke—Legal Resiliency

For trade lawyers and corporate compliance officers, the move from the International Emergency Economic Powers Act to Section 301 represents a strategic legal pivot with far-reaching implications. After the Supreme Court invalidated the earlier 'reciprocal' tariffs, the administration grounded its new duties in a statute that has repeatedly withstood judicial and WTO scrutiny—reducing the immediate litigation risk but raising new questions about forced-labor determinations and product scope.

The Trump administration is set to implement a new regime of tariffs on Friday, July 24, 2026, as temporary 10% duties on all international imports expire. The latest trade action imposes rates of 10% and 12.5% on goods from 60 trading partners, including the European Union, under Section 301 of the Trade Act of 1974, citing lax enforcement of forced labor prohibitions abroad. These duties cover an extraordinary 99.4% of all U.S. imports, effectively maintaining a tariff floor across virtually the entire economy after the Supreme Court struck down the administration’s previous “reciprocal” tariffs in February 2026.

The latest trade action imposes rates of 10% and 12.5% on goods from 60 trading partners, including the European Union, under Section 301 of the Trade Act of 1974, citing lax enforcement of forced labor prohibitions abroad.

The February ruling invalidated tariffs of 10% to 50% that had been imposed under the International Emergency Economic Powers Act (IEEPA), dealing a major blow to President Trump’s trade agenda. In response, the White House quickly imposed a temporary 10% global tariff for 150 days to buy time. That stopgap expires at 12:01 a.m. EDT on Friday, precisely when the new forced-labor duties take effect, with a brief window for goods in transit until July 28. The seamless transition ensures no gap in protectionist measures, preserving the concept of a near-universal U.S. tariff.

By grounding the tariffs in Section 301, the administration taps a legal authority that has survived decades of court challenges and World Trade Organization scrutiny. Unlike IEEPA, which the Supreme Court deemed insufficient for broad, non-emergency tariffs, Section 301 grants the U.S. Trade Representative sweeping powers to retaliate against foreign trade practices deemed unfair. The forced-labor framing adds a humanitarian gloss, potentially insulating the duties from some legal attacks and making it harder for trading partners to mount WTO challenges based on pure protectionism.

For global supply chains, the impact is immediate and pervasive. With 99.4% of imports affected, businesses from retailers to manufacturers face a minimum 10% cost bump on nearly all foreign-sourced goods. Exemptions for oil and gas, fertilizer, and certain food items provide critical relief for energy and agricultural inputs, but the vast majority of consumer products, industrial components, and electronics will feel the squeeze. Importers must rapidly update customs documentation, assess new classification risks, and potentially reroute supply chains to countries not on the list of 60 targeted partners—though those appear to encompass all major U.S. trade partners, leaving little room for avoidance.

The dual-rate structure (10% and 12.5%) hints at a tiered enforcement system, likely tied to the U.S. assessment of each country’s forced-labor record. However, the Federal Register notice does not publicly detail which countries face the higher rate, creating significant uncertainty for compliance officers. The 150-day temporary tariff period already exposed importers to elevated costs, and the new duties cement those costs into a more permanent policy framework, with no expiration date.

From a trade diplomacy perspective, the move escalates tensions with allies like the EU. U.S. Trade Representative Jamieson Greer’s statement frames the action as a moral imperative rather than a revenue-generating measure, but economists warn that broad tariffs ultimately function as regressive taxes on American consumers and businesses. Retaliation is likely: the EU, China, and others may challenge the tariffs at the WTO or impose countermeasures, especially if they view the forced-labor rationale as pretextual.
