Michael Calvert (37), Steven Moore (39) and Daniel King (33) will remain in police custody until they appear in the Magistrate’s Court on Monday.
They were three of five men arrested yesterday in connection with the crime, following a joint operation between the States police and Customs.
One of the other men has been released on bail, while the fifth has been released.
The police say they will not know the nature of the drugs until they are analysed.
