President Donald Trump On Saturday, he said he would increase global tariffs by 10% to 15%, a day after the Supreme Court ruling struck a large part of the president’s trade agenda.
In a Truth on social mediaTrump said the new tariffs would take effect “immediately.” He also warned that additional levies would follow.
“As President of the United States of America, I will, effective immediately, increase global tariffs from 10% on countries, many of which have been ‘ripping off’ the United States for decades, without retaliation (until I arrive!), to the fully authorized and legally tested 15% level,” he wrote.
“Over the coming months, the Trump administration will determine and publish the new legally authorized tariffs,” he added.
Trump’s announcement claimed the new tariffs would take effect without delay, but it is unclear whether any official documents have been signed detailing the timeline. A White House information sheet released on Friday, it indicated that the initial 10% rates would take effect on Tuesday, February 24 at 12:01 a.m. ET.
The White House did not immediately respond to a request for clarification from CNBC.
Trump, who is planned to deliver his State of the Union address to Congress on Tuesday, received a blow Friday when the Supreme Court decided in a 6-3 tariff decision that the President wrongly invoked the International Emergency Economic Powers Act (IEEPA) to implement his levies.
On Friday, Trump responded hours after the decision with a Global rate of 10% which he invoked under Section 122 of the Commerce Act of 1974. The law authorizes the president to impose temporary levies for 150 days. Any extension requires congressional approval.
The president was scathing in his remarks against the Supreme Court’s decision, calling it “ridiculous, poorly written and extraordinarily un-American” in a social media post.
He also attacked Justices Neil Gorsuch and Amy Coney Barrett after they voted with the majority in the decision.

Republicans were more divided on the issue. Some criticized the Supreme Court’s decision, while others argued that Congress had the constitutional authority to implement levies.

How the U.S. government will make reimbursements remains a question. According to one estimate, the US government could I owe over $175 billion in refunds to importers following the Supreme Court decision.
