Brexit is getting ever more tricky for Irish firms

In her keynote Brexit speech last week, British Prime Minister Theresa May reiterated her opposition to a customs union. Ms May was clear she wants the UK to be able to set its own tariffs for goods intended for the UK market but that it will apply EU tariffs and the same rules of origin for those goods destined for the EU. Hence for Irish exporters selling into the UK, there would be a return to tariffs and certificates of origin as applies under the World Trade Organisation rules.
However, for Irish businesses importing from the UK there may not be any of these changes if the goods originated from within the EU or a certain percentage of the ingredients originated in the UK but a higher percentage came from other EU countries.
