Border Force officers stopped the shipment on Thursday in the UK inbound zone of Coquelles, France. The 921-pound load has a street value of more than $44 million.
Piotr Perzenowski, a 30-year-old man from Poland, is facing a charge of smuggling class A drugs.
"This was a really significant amount of drugs taken out of circulation," National Crime Agency Branch Commander Mark Howes said in a statement.
"The seizure will deprive the [organized] crime group responsible for them of profit which would have fuelled more offending."
The $44 million bust comes on the heels of other recent blows to drug trafficking rings in Europe.
Portuguese police seized five tons of cocaine off a yacht in the Atlantic Ocean last month. U.S. and European law enforcement officials also dismantled a massive darknet drug trafficking network in October, resulting in the arrest of more than 150 people and the seizure of hundreds of pounds of various drugs.
