The list shows what is being currently exported from UK to EU- but it does not have to be. Europe can quite easily import/export to each other for those on your list. They did so from the UK when they were partners, and when transport was easy and cheap, and no redtape, taxes or checks, no delays at ports, no tarifs. Now it has got so complictated, if the UK slaps tariffs, then they will just stop buying from UK and just buy and sell from each other. As said, I can't think of any product they could not just stop buying from UK- apart from good Malt Whisky.
