Officers from Revenue's Customs Service have today seized 38 million cigarettes at Dublin Port.
The cigarettes were in four forty-foot maritime containers.
The cigarettes seized have a retail value of €14.7million with a potential loss to the Exchequer of €13.1million.
The "Golden Eagle" brand cigarettes, which originated in Vietnam and arrived into Dublin via Rotterdam, were described as 'wood briquettes' on the manifest and were consigned to an Irish-based company.
Approximately 9.5m cigarettes were seized from each of the four containers.
"This seizure, which was the result of profiling by Revenue's Customs Service, is a significant blow to the criminals involved in this illicit trade," said Revenue Commissioner Liam Irwin.
"Tobacco smuggling is organised fraud on a global scale - it brings criminality into our communities and robs millions of euro from the State each year."
Several individuals were interviewed and a premises was searched under warrant following the seizure.
Investigations are ongoing.
