Steven David Herring (29) pleaded guilty to the Class A drug offence in the Royal Court on Friday.
The Court was told that the incident took place on 30 October last year at the Jersey Airport.
Customs and Immigration seized approximately 80g to 90g of the Class A drug from Herring, who was smuggling the drug internally.
Herring was represented by Advocate Alana Binnie, who entered a ‘guilty’ plea on her client’s behalf.

Crown Advocate Chris Baglin appeared for the prosecution.
The Lieutenant Bailiff Anthony Olsen presided over the hearing and the case was heard by Jurats Blampied and Dulake.
Herring was remanded in custody until his sentencing on 2 April before the Superior Number – a panel of five or more Jurats who only sit to hear the most serious criminal cases.
