Trump revealed the tariff decision in a May 1 Truth Social post, one day after the British royal couple left the White House. The president framed the move as a gesture honoring the visiting sovereigns, stating he would remove tariffs and restrictions on whiskey related to Scotland's work with Kentucky on whiskey and bourbon production.

"In Honor of the King and Queen of the United Kingdom, who have just left the White House, soon headed back to their wonderful Country, I will be removing the Tariffs and Restrictions on Whiskey," Trump wrote in his announcement. He characterized both whiskey and bourbon as "very important Industries within Scotland and Kentucky."

Trump attributed the policy shift to the royal visit itself, noting that trade barriers between the nations had long been an issue. He referenced the role of wooden barrels in facilitating inter-country commerce, saying the discussion had been desired for an extended period. "The King and Queen got me to do something that nobody else was able to do, without hardly even asking!" he added.

A Buckingham Palace spokesperson responded to the announcement on behalf of King Charles, expressing the monarch's gratitude for Trump's decision. The palace statement indicated the tariff removal would benefit the British whisky industry and its workers. "His Majesty will be raising a dram to the President's thoughtfulness and generous hospitality as he departs the US after a most enjoyable State Visit for both Their Majesties in this special anniversary year," the statement read.

The tariff elimination concluded what both the palace and Trump characterized as a successful state visit, with the gesture serving as a diplomatic conclusion to the royal couple's time in the United States.
