On the 20th, the U.S. Supreme Court ruled that the U.S. government's imposition of large-scale tariffs was &#34;beyond authority.&#34; In response, President Trump immediately issued a new executive order, announcing a 10% import tariff on goods from all countries and regions starting February 24, 2026.
On the 21st, Trump announced that the newly imposed &#34;global import tariff&#34; rate would be raised from 10% to 15%. Meanwhile, the impact of the Supreme Court's ruling was also becoming evident. As of the 21st, hundreds of companies had filed lawsuits seeking refunds for tariffs paid due to Trump's tariff policy.
<h2>One day after the increase of the &#34;global import tariff,&#34; Trump announces the new tariff rate will be raised to 15%</h2>

△ Trump announced on social media that the 10% &#34;global import tariff&#34; rate would be raised to 15%.
In his statement, Trump said, &#34;Based on a comprehensive, detailed, and complete review of the U.S. Supreme Court's ruling on tariffs made on the 20th — the ruling is absurd, poorly worded, and extremely anti-American,&#34; and that he would immediately raise the current 10% uniform tariff imposed on all countries to a legally permissible and validated level of 15%.
Trump stated that in the coming months, the U.S. government would determine and announce new tariff measures that are legally permissible.
<h2>U.S. Supreme Court rules original tariff policy &#34;beyond authority&#34; — Trump issues new regulations based on other laws</h2>
On the 20th, local time, the U.S. Supreme Court ruled that the large-scale tariff measures implemented by the Trump administration under the International Emergency Economic Powers Act lacked clear legal authorization.
On that day, the Supreme Court justices upheld the lower court's ruling by a vote of 6 to 3, determining that Trump's invocation of the International Emergency Economic Powers Act to implement tariff policies exceeded his statutory authority. The Supreme Court reached this conclusion in lawsuits filed by businesses and 12 states in the U.S. These businesses and states argued that Trump's unilateral imposition of import taxes based on this law was unprecedented.
However, the Supreme Court's ruling only restricts the president's ability to impose tariffs under the International Emergency Economic Powers Act and does not completely strip him of the power to levy tariffs. Following the ruling, Trump on the 20th turned to Section 122 of the Trade Act of 1974 to announce the imposition of a &#34;global import tariff&#34; at a rate of 10% for a period of 150 days, to replace the tariffs deemed illegal by the Supreme Court.
<h2>Hundreds of Companies File Lawsuits Demanding &#34;Refunds&#34;</h2>
On the 21st, as Trump announced an increase in the &#34;global import tariff&#34; rate from 10% to 15%, the impact of the U.S. Supreme Court's ruling on the previous tariff policies of the Trump administration is also spreading.
As of the 21st, hundreds of companies, including major retailer Costco, have filed lawsuits demanding refunds for payments made under the tariff policies deemed &#34;overreaching&#34; by the U.S. Supreme Court.
According to data from U.S. Customs and Border Protection last December, tariffs imposed by the Trump administration under the International Emergency Economic Powers Act have accumulated approximately $130 billion. An estimate from the University of Pennsylvania suggests that this total may now exceed $175 billion.
Economists point out that the process for companies to apply for refunds on paid tariffs is currently not clear, but U.S. companies eligible for refunds are not the only group bearing the economic burden of Trump's tariffs.
<h2>“Overreaching” Tariffs Create a Large “Confusing Account” Trump: May “Fight Legal Battles for Five Years”</h2>
Additionally, some analysts believe that the tariff policies ruled &#34;overreaching&#34; have created a large-scale “confusing account”. Data shows that the costs of tariffs are almost entirely borne by U.S. domestic companies and consumers. A group of economists from the New York Federal Reserve analyzed import data up to last November and found that nearly 90% of the economic costs associated with tariffs fell on U.S. companies and their customers. However, the reality is that ordinary consumers cannot prove how much tariff they have borne, and thus have no eligibility for refunds, and many small businesses have not fully passed on the tariffs to consumers in order to maintain market share, making it impossible to calculate this account now.
Therefore, with the U.S. Supreme Court having issued a clear ruling, the judicial lawsuits surrounding the tariff policies implemented by the Trump administration under the International Emergency Economic Powers Act will become increasingly numerous and complex.
Trump himself acknowledged on the 20th, the same day he announced the new tariff policy, that the Supreme Court ruling will trigger a prolonged legal battle regarding whether the federal government must refund tariff payments to U.S. companies, which may “take five years of litigation”.
