Mohamed Imran Khan Sathar Khan, 35, was jailed for three years and nine months last September after admitting two counts of money laundering.
On 29 August 2018 he checked four suitcases in at Stansted Airport – each weighed 20kg and all were rammed with £10 and £20 notes.
National Crime Agency officers launched an investigation after Border Force officers stopped Khan, of no fixed abode, from boarding the aircraft.
A forfeiture order made for the cash was signed off by Canterbury Magistrates Court.
Matt Rivers from the NCA said: “The forfeiture order demonstrates our determination to remove the proceeds of crime from organised criminals. Over the past year we have investigated cash seizures at UK borders totalling more than £8 million.
“In this case, with the help of our partners, we were able to intercept the cash during the money laundering process. Our investigation continues in relation to the wider criminal network behind this seizure.”
