With effect from Tuesday this week, all food or animal feed products transiting through Northern Ireland from the EU will be subject to UK border controls. These will not apply to food or feed products that are processed or originate in Northern Ireland by Northern Ireland-registered processors.What this means is that exporters from the Republic of Ireland that use Northern Ireland ports for exporting to Britain will be subject to the same border controls as those that export through either Dublin or Rosslare ports. This will also apply to any other EU or global product as well as Irish-origin production.
