Trump’s immediate response to the Supreme Court tariff ruling: 10% global tariffs announced, legal pivot unveiled, ‘disloyal’ justices targeted amid trade turmoil

Trump’s immediate response to the Supreme Court tariff ruling: President Donald Trump moved within hours of the Supreme Court’s 6–3 ruling to preserve his trade agenda, announcing a 10% global tariff under a different statute and sharply criticizing “certain” justices — including some he nominated. The Court invalidated tariffs imposed under IEEPA, but left other trade laws untouched. Trump said “other alternatives will now be used,” signaling an aggressive legal pivot to maintain duties while Congress weighs next steps.

The President claimed, without providing evidence, that the Court had been "swayed by foreign interests" and labeled the decision a "disgrace to our nation." This direct assault on the conservative majority he helped build marks a significant fracturing of the relationship between the White House and the High Court, signaling that future executive orders on immigration and federal personnel may face equally tough judicial scrutiny.

10% global tariff under Section 122 of the 1974 Trade Act

Trump’s first move is Section 122 of the Trade Act of 1974. It allows tariffs of up to 15% for 150 days without prior congressional approval. The White House set a 10% global rate.


This tool is narrower and temporary. After 150 days, Congress must approve any extension. That makes Capitol Hill the decisive arena for the tariff strategy’s survival.

Economists note the immediate effect could be broad-based import cost increases, depending on product scope. Markets are assessing pass-through to consumer prices and supply chains.

Section 301 investigations and existing duties remain

Trump also directed new investigations under Section 301 of the 1974 Trade Act to address “unfair trading practices.” Section 301 is slower but potentially more durable, as it follows formal probes and can justify targeted tariffs.

At the same time, national security tariffs under Section 232 of the 1962 Trade Expansion Act remain in force. The Supreme Court ruling was limited to IEEPA-based levies, so Section 232 and existing Section 301 tariffs are unaffected.

The message is clear: while one pathway was closed, multiple statutory routes remain open.

The more politically explosive development was Trump’s direct attack on members of the Court. He labeled “certain” justices “unpatriotic and disloyal to our constitution” and claimed, without evidence, that the Court had been “swayed by foreign interests.”

Those remarks likely include justices he appointed, such as Neil Gorsuch and Amy Coney Barrett. It is unusual for a president to publicly criticize his own nominees for ruling against him in a separation-of-powers dispute.

Constitutional scholars say the episode underscores the Court’s willingness to limit executive authority, even in high-stakes trade policy.

Section 122 buys roughly 150 days of tariffs. It is capped at 15% and expires without congressional extension. That makes the next phase political, not just legal.

If Congress cooperates, the tariffs could continue. If not, they lapse. In parallel, Section 301 investigations could lay groundwork for longer-term, country-specific duties.

Existing Section 232 and National Security Tariffs Remain

It is critical for traders and businesses to note that the Supreme Court ruling is not a total repeal of all current trade duties. Specifically:

• Section 232 Tariffs: Duties on steel, aluminum, and certain semiconductors remain fully in place, as they are based on a different 1962 law that was not the subject of this case.
• Section 301 China Tariffs: The majority of product-specific tariffs targeting Chinese technology and intellectual property are also unaffected.
• Refined Revenue: Even with the IEEPA loss, the remaining legal tariffs are projected to raise $635 billion over the next decade, costing U.S. households roughly $400 in 2026 alone.

The ruling provides a temporary reprieve from "Liberation Day" duties, but with the President already deploying alternative legal tools, the 2026 trade landscape remains defined by volatility and "governing by decree."

For businesses and global markets, uncertainty remains elevated. The administration has preserved short-term leverage. The long-term trade war strategy now hinges on Capitol Hill.

Watch Congress closely.
