Drugs worth around €9.8m have been seized on their way into Dublin Port.
Gardaí said the seizure came on the back of a joint operation involving Revenue and the Garda National Drugs and Organised Crime Bureau (GNDOCB).
The cocaine, heroin, cannabis and ketamine were found hidden in a furniture consignment that arrived in from the Netherlands.
Revenue Detector Dog Robbie sniffed them out while officers searched using the Mobile X-ray Scanner.
A follow-up search in Dublin then uncovered around 960kgs of tobacco, worth more than €600,000.
Gardaí are working with international law enforcement partners as part of the ongoing investigation.
