The Supreme Court ruling that nullified global tariffs from United States President Donald Trump has created renewed uncertainty for many of its major trade partners – and a clear vindication for its biggest economic rival: China.

The Supreme Court decision striking down President Donald Trump’s sweeping tariffs has added a wrinkle to already complicated U.S.-China relations.

Trump's new blanket tariff, valid for 150 days, will take effect on February 24.

The change surprised executives and foreign leaders, who had been expecting the 15 percent rate the president announced on Saturday.

Chinese electric vehicle manufacturer BYD is suing the Trump administration over tariffs the company says makes it costly to enter the U.S. market.

For Michael Kersey, president of the American Lawn Mower Company, these solicitations represent an existential threat. “Tariff cheating is much, much worse than tariffs for us,” said Kersey, who began outsourcing production to China two decades ago and paid as much as 45% to bring those goods into the US over the last year.

The United States imposed a new tariff from Tuesday of 10% on all goods not covered by exemptions, the U.S. Customs and Border Protection said, the rate first announced by President Donald Trump on Friday rather than the 15% he promised a day later.
