President Donald Trump is imposing new tariffs under Section 301 of the Trade Act to rebuild his trade wall [1].
This shift follows a Supreme Court ruling issued last Friday that declared the administration's earlier "reciprocal" tariffs illegal. By pivoting to Section 301, the White House seeks a more durable legal authority to maintain its protectionist trade policies and circumvent the judiciary's setback [1, 5].
The administration's strategy includes a series of targeted duties. A temporary tariff rate of 10% was imposed following the court's decision, though that specific measure expired on July 24, 2026 [1, 2]. To replace these measures, the administration has launched Section 301 probes into 60 trading partners [5]. These partners face tariffs ranging from 10% to 12.5% [5].
Some specific nations are facing significantly higher penalties. The administration has applied 25% duties on imports from Brazil [3]. Meanwhile, the U.S. has proposed tariffs of 50% on goods coming from Canada [3].
The move represents a race against the clock for the White House to secure its trade perimeter [4]. By using Section 301, the administration can argue that these tariffs are responses to unfair trade practices rather than simple reciprocity. This legal distinction is intended to shield the duties from further constitutional challenges in the courts [2, 5].
Washington officials said the actions are necessary to protect domestic industries. The shift to Section 301 allows the executive branch to maintain leverage in bilateral negotiations, while the administration attempts to rebuild the economic barriers it previously established [1, 4].

The transition from reciprocal tariffs to Section 301 authority signals a strategic legal pivot by the Trump administration. While the Supreme Court limited the president's ability to mirror other countries' tariffs directly, Section 301 provides a broader mandate to penalize 'unfair' trade practices. This allows the administration to maintain a protectionist stance while attempting to find a legal loophole that satisfies judicial scrutiny.
