According to Revenue, 84% of freight vehicle (ro-ro) movements into Ireland from Britain through the ports of Dublin and Rosslare since January 1 were "green routed", meaning they did not require any checks on arrival.
A further 12% were "orange routed" for a documentary or similar check, reports RTE News.
The remaining 4% were "red routed" for a physical examination or inspection of goods, although this does not always imply non-compliance.
In total, Revenue said there have been 186,500 vehicle movements since the formal departure of the UK from the EU took effect at the start of the year, exactly six months ago today.
"The significant and permanent change in trading arrangements with Great Britain since 1 January last represents the biggest challenge for trade and business in Ireland in almost 30 years, since the creation of the EU Single Market," said Gerry Harrahill, Revenue Commissioner and Director General of Customs at Revenue.
However, the volume of goods imported from the UK has fallen considerably this year compared to last year and pre-pandemic, down 31% in March and 20% in April, according to the most recent figures from the Central Statistics Office.
