US President Donald Trump announced he will remove all tariffs on Irish whiskey, ending a 15% levy that applied to whiskey distilled in the Republic of Ireland as part of standard EU import tariffs to the US. The announcement came as he concluded a two-day visit to Ireland, made while presenting the winner's trophy to Shane Lowry at the Irish Open at his Trump International golf resort in Doonbeg, County Clare, and matters because it removes a competitive disadvantage that Irish whiskey producers faced compared with UK-made whiskey, which had already been exempted from tariffs in May.

Trump said he had discussed the tariffs with Taoiseach Micheál Martin and with Lowry before making the decision "on behalf of the United States of America". The move is expected to particularly benefit Northern Ireland distilleries that use all-island supply chains, such as those bottling whiskey produced under licence by the Great Northern Distillery in Dundalk, County Louth, which had previously been classed as EU rather than UK producers and so missed out on the earlier tariff removal. The visit also saw Trump reiterate support for a united Ireland, calling it "one of the naturals of all time", comments Martin said were unsurprising given the president's previously stated views.
