Subsequently, Trump confirmed through social media platforms that the decision will officially take effect on June 4th.
On the same day, the White House also released a statement on social media stating that "in order to further protect the US steel industry from unfair competition from foreign countries, starting next week, the US import steel tariffs will be raised from 25% to 50%." As early as February 10th, Trump had signed an executive order announcing a 25% tariff on all steel and aluminum imported into the United States. On March 12th local time, the 25% tariff on steel and aluminum officially came into effect. Now it needs to be increased from 25% to 50%.
