No, President Donald Trump did not postpone a tariff ban for 90 days. While there were discussions and rumors about potential tariff pauses or exemptions, the White House denied claims of a 90-day pause as “fake news.” On April 9, 2025, Trump’s tariffs on numerous imports, including those from China, Vietnam, and Taiwan, officially took effect, leading to significant price hikes and market disruptions[2][3]. However, prior to this, there had been a brief 30-day pause for certain tariffs targeting Mexico and Canada, which was unrelated to any broader 90-day suspension[1][3].
