Cannabis hidden in car seat covers was seized during a Dublin Airport raid on Wednesday.
Revenue officers found 6.9kg of the drug when examining parcels at a warehouse facility in two separate operations.
The cannabis was hidden in packages labelled 'car seat covers' that had arrived in from the United States.

The so-called car seat covers were on their way to addresses in Dublin and Kildare.
Meanwhile, on Tuesday Revenue officers were granted a three-month cash detention order by Judge Paula Murphy in Dublin District Court.
This followed on from a sting on Monday where €15,000 in cash was seized at Dublin Airport.
The huge sum was discovered when a passenger was searched before boarding a flight to Alicante.
The cash is suspected to be the proceeds of, or intended for use in, criminal activity.
A revenue spokeswoman said: "Investigations into these seizures are ongoing.
"These seizures are part of Revenue's ongoing operations targeting the importation, sale and supply of illegal drugs and the shadow economy.
"If businesses or members of the public have any information regarding smuggling, they can contact Revenue in confidence on Confidential Phone Number 1800 295 295."
