Almost 10 million cigaretts, worth nearly €9 million, have been seized at Dublin Port.
Revenue officers discovered the illegal cigarettes on Monday in an unaccompanied container that had arrived from the Netherlands.
The 9.9 million cigarettes were branded Marlboro Gold, Richmond Blue, and Marlboro Red.
Revenue said the seizure represents a potential loss to the Exchequer of over €7 million.
The cigarettes were found following risk profiling and the use of Revenue's mobile x-ray scanner.
Revenue said their investigations into the seizure are ongoing.
