At the trophy presentation for the Irish Open on 13 September, at the end of a two-day visit to Ireland, Donald Trump said he would remove the tariff the US applies to Irish whiskey. This affects how Northern Ireland distillers price a bottle for the US market, and it affects them differently. Some currently sell into the US with a price advantage over their Republic of Ireland rivals, which this move would remove. Others are Northern Ireland companies that have been paying the same 15% tariff as those rivals because of where their whiskey is distilled, and they would gain.
The tariff depends on origin. Whiskey distilled in the Republic of Ireland currently faces the US’s standard 15% tariff on EU goods. Whiskey made in Northern Ireland, like whiskey made anywhere else in the UK, currently faces none, because Trump lifted the UK-wide whiskey tariff back in May. For a Northern Ireland bottle, the tariff depends on where the whiskey was distilled.
What Trump said, and the current US tariffs
Trump made the announcement at his golf resort in Doonbeg, Co. Clare, while handing the winner’s trophy to Shane Lowry, that week’s Irish Open champion. He said the subject had come up in conversation with both Taoiseach Micheál Martin and Lowry: “Everybody’s been bugging me. They are saying would you do me a favour? It’s so unfair what’s going on. Could you possibly take the tariffs off of Irish whiskey and I said, on behalf of the United States of America, I am going to take the tariffs off Irish whiskey.” That is a spoken commitment made at a trophy ceremony, with no published notice from the US Trade Representative or signed executive order behind it yet. What was already settled, and has been since May, is the 0% US tariff on UK-made whiskey, Northern Ireland included.
Distillers whose whiskey is made in Northern Ireland
If your Northern Ireland distillery mashes, ferments, distils and matures its own whiskey on Northern Ireland soil, both HM Revenue & Customs and US Customs treat the finished bottle as UK-origin. That has meant a 0% US tariff since May, against a 15% tariff on the same style of whiskey coming from Dublin, Kilkenny or Cork. BBC News NI’s economics and business editor, John Campbell, put it plainly in his analysis of the announcement: assuming the Irish whiskey tariff is actually removed, it ends the advantage Northern Ireland distillers have held over their Republic of Ireland competitors. US importers take the tariff into account when deciding which bottles to stock.
| Illustrative Co. Antrim distillery — own stock, UK-origin | Value |
|---|---|
| Export volume | 3,000 cases/year |
| FOB export value (£600/case) | £1,800,000 |
| Tariff a Republic of Ireland rival currently pays (15%) | £270,000 |
| Tariff this Northern Ireland distillery currently pays (0%) | £0 |
| Gap that disappears once Irish whiskey drops to 0% | £270,000/year |
None of that £270,000 was ever a cost to the Antrim distillery — it’s the gap between what it currently pays and what a Cork or Dublin competitor currently pays on the same value of exports to the same market. Once that gap closes, the Antrim distillery’s own costs and its own 0% tariff don’t change. What changes is that a US importer no longer has £270,000 a year of reason to prefer the Northern Ireland bottle over the Republic of Ireland one on price alone. Build that into next year’s US sales forecast now.
Northern Ireland brands with whiskey distilled in the Republic
There’s a second group of Northern Ireland distilleries this cuts the other way for, and it comes down to a detail the BBC’s own coverage flagged directly. UK law requires whiskey to mature in cask for at least three years before it can be sold as whiskey, so a newly opened Northern Ireland distillery can be trading, and exporting, years before its own stock is ready. Many bridge that gap by selling whiskey bottled under their own label but distilled under contract elsewhere — and the dominant supplier of that contract-distilled liquid across the island is the Great Northern Distillery in Dundalk, Co. Louth, in the Republic of Ireland. For customs purposes, origin follows where the spirit was actually distilled. A Northern Ireland company selling Dundalk-distilled whiskey under its own brand has, for tariff purposes, been an EU exporter — paying the same 15% as a distillery in Cork, despite being a Northern Ireland business in every other sense.
| Illustrative Co. Down distillery — own stock maturing, sourced under contract from Dundalk | Value |
|---|---|
| Export volume | 400 cases/year |
| FOB export value (£500/case) | £200,000 |
| Tariff currently paid (EU-origin classification, 15%) | £30,000 |
| Annual saving if this liquid drops to 0% | £30,000/year |
That’s the mirror image of the Antrim example : a real cash saving, which only lands if the tariff cut actually reaches whiskey classified as EU-origin. Which distilleries sit in this position is not public information. Check your own import paperwork.
What to do this week
Establish, on paper, where the spirit in your bottle was actually distilled, and confirm that matches the customs classification your US importer is using. nibusinessinfo’s guide to exporting to the USA is the right starting point for the paperwork itself.
Don’t let a US importer or distributor reprice your product on the strength of a trophy-ceremony announcement that hasn’t yet appeared as a US Trade Representative notice. Our tax planning work can model what cross-border origin does to your margin, and any change to next year’s US sales belongs in your business plan.
What is still uncertain, and when we’ll know
Three things aren’t settled yet. First, mechanism: Trump’s comment at Doonbeg was spoken, and there is no US Trade Representative notice or Federal Register filing implementing it as of 14 September 2026. Second, scope: it isn’t yet clear whether a removed tariff would apply to whiskey classified for tariff purposes as Irish, to all Republic of Ireland-origin spirits, or to EU goods more broadly — and that distinction decides whether Dundalk-distilled, Northern Ireland-bottled whiskey actually benefits. Third, timing: the May removal of the UK-wide whiskey tariff took weeks to move from announcement to implementation, and there’s no reason to expect this one to move faster. Watch for a USTR notice or Federal Register filing.
