Trump tariffs have triggered one of the biggest constitutional standoffs in recent U.S. trade history. On February 20, 2026, the Supreme Court struck down the sweeping emergency duties in a 6-3 ruling, finding that IEEPA — the emergency law the White House had been relying on — does not authorize the president to levy tariffs. In Trump tariffs news today, the administration responded fast:Trump signed a new executive order within hours, imposing a 10% global tariff on all countriesunder Section 122 of the Trade Act of 1974. The new Trump tariffs take effect February 24, and Congress would need to act to extend them beyond 150 days.

Chief JusticeJohn Roberts, writing the majority opinion in the Trump tariffs Supreme Court case, explained why the president’s emergency powers fell short. He stated:

“When Congress grants the power to impose tariffs, it does so clearly and with careful constraints. It did neither here.”

Trump was not exactly measured about it. At the White House press briefing, he called the ruling “deeply disappointing” and said:

“I’m ashamed of certain members of the court, absolutely ashamed, for not having the courage to do what’s right for our country.”

He also referred to the justices who ruled against his tariff policy as “fools and lapdogs,” adding:

“But it doesn’t matter because we have very powerful alternatives.”

The Trump tariffs China situation has shifted and by the time of writing, the figures are huge. In China, there had been two layers of IEEPA-based 10% duty, in addition to a 25 percent Section 301 tariff, 45 percent combined. As IEEPA is now cut we have a total rate of 35 percent in China on the new global flat rate. BRICS countries, such as India, Brazil and South Africa, all three have once had increased reciprocal IEEPA rates, so the 10% flattened may prove to have a reduced practical load, at least within the 150-day period.
