Irish tax bosses will temporarily ease customs arrangements for businesses importing goods from the 海角视频 - in a move that should boost Welsh ports.
Last night between Holyhead and Dublin, and Fishguard and Rosslare.
This follows a 70% slump in freight trade on the routes as businesses struggle with new customs arrangements after the end of the transition period on December 31.
In Ireland this has sparked concerns about empty shelves in supermarkets as goods fail to arrive.
On Thursday night, the Irish Revenue Commissioners issued a general code to allow traders and hauliers to circumvent customs arrangements for a temporary period.
They said: "Revenue recognises the some businesses are experiencing difficulties in lodging their safety and security ENS (entry summary) declaration in respect of RoRo goods movements. In response, Revenue is implementing a temporary easement to alleviate these current difficulties."
This will allow traders to ship goods that they have struggled to move over recent days.
The problem has not been ports turning away vast amounts of traffic but that those goods are not even leaving 海角视频 warehouses as retailers and hauliers try to get to grips with new paperwork.

"Yes, the pre-December 31 stockpiling accounts for some of the drop in trade in the new year, but Stena and Irish Ferries moving ships to bolster their direct Ireland-France sailings shows the big increase in demand for avoiding the Uk landbridge.
"The question at this stage is ‘is this a temporary phenomenon’? I sincerely hope it is, because any long term change of this kind in trading patterns can only be bad for jobs in Holyhead."
