If it is something small there should not be a problem. Ireland do not have a stringent import authority
They import Guiness and Silver
chickens
New Zealand
As far as I know the Germans and Swiss are big exporters of chocolate to the U.S.
Canada imports chocolate from belgium
Coffee beans and chocolate.
Alcohol of course
pretty much everything! (its an island)
Coal, sand, waste, wood
Oysters. Guinness. U2.
Irish people like oranges but they don't grow in Ireland, so they have to be imported.
