And as far as trade tariffs go all the EU and UK need to do is not impose them between Northern Ireland and the republic the trade is microscopic anyway. Problem solved
And how would you deal with let's say Chinese goods which will have different tariffs in UK and EU?
I dont know. I might know if I was running the negotiations. However it does not seem impossible to solve although I think plenty of remainers are clinging to the hope the irish border cant be solved with 95% of the deal complete TM says 95% the EU 90% but sounds like we are getting there. What an earth are you and the remoaners (not remainers) going to do if they solve the border issue? Which I am absolutely certain they will. And Shaggy please try please ! yes the EU has rejected the proposal but what happens is both sides will amend and ajust and repackage give it a new name (say the facilitation option) and bingo a deal is done. Thats the way these complex political disputes work both sides have to be seen to win. And Vish not sure any chinese goods go to Ireland not sure they have the ports in Ulster maybe dublin does but almost all chinese goods come in via the deep water ports on the english south coast and brought to ireland via lorry or train so the customs can be handled by software and bar code in those ports
So, according to what you wrote, a container with Chinese goods will dock in UK and will be transported to Ireland by road, but then who collects the duty and where? Let's say as you say, barcodes and software solve this, then how do you distinguish a product in a container which is consigned to ROI and the same product in a container consigned to NI? You can't as it will be the same product, however, the duties will be different as trade deals will be negotiated separately. Still with me? As the duties would be different so would the landed costs, right? Let's say duties in UK, the new tax haven, are lower than in ROI, then if there is no border, those goods from UK will be smuggled to ROI to be sold there, or anywhere else in EU. Do you get it now? To solve this, you need to remain in the customs union as I said before and which Labour is saying now.
