Yes, but only for EU goods transiting Ireland to NI or onwards to the UK, the reverse would also be true. Goods destined only for Ireland or Irish goods for the EU would be treated as now.
What will not happen is that the current Irish coastal border will become a border between Ireland and the EU as EU treaties and rules do not allow for it.
There is already a border round Ireland for goods from the ROW, but not for EU goods, they can enter through any port. That will remain the case. There are similar borders on the Scottish Islands, and Orkney and Shetland, and Great Britain while the UK is part of the EU. EU goods pass through, ROW goods are checked.
If there is a no-deal Brexit the Ireland border will run inland from Muff to Warrenpoint and thus complete Ireland's border to third countries (the UK) and the ROW. On the NI side the border will become part of the UK's external border with the EU and the ROW.
