U.S. President Donald Trump said on the 22nd (local time) that he would impose higher tariffs on countries that take advantage of the Supreme Court's ruling on reciprocal tariffs being illegal.
On Truth Social the same day, President Trump said, "Any country that tries to play games by using the ridiculous Supreme Court decision—especially countries that have been leeching off the United States for decades—will face tariffs far higher than those we recently agreed to."
At the end of the post, President Trump added the commercial warning phrase "buyer beware" (BUYER BEWARE). This is interpreted to mean that if a country that agreed to large-scale investment or to import U.S.-made products in exchange for lowering tariff rates reneges on the deal by citing the Supreme Court's illegal ruling, punitive tariffs will be imposed.
After the Supreme Court ruled that the tariffs he imposed were illegal, President Trump immediately signed a proclamation imposing a 10% global tariff for 150 days. He then announced that he would raise it to 15%.
