In 2013, 4.7 tons of cocaine were seized. That rose to 62.1 tons in 2019, and now 65.48 tons in 2020, the finance ministry said in a statement.
The drugs come from Latin America — principally Colombia, Brazil and Ecuador — and are usually found hidden away in cargo containers offloaded from ships.
Belgium is the top destination for the shipments, followed by Spain and the Netherlands, with the drug consignments broken up then distributed across Europe for sale.
The finance ministry estimated the street value of the drug seized last year at €7.5 billion ($9.2 billion), based on the average 68.50-euro price for a gram of 60-percent pure cocaine.
Antwerp is Europe's second-biggest port, after Rotterdam in the Netherlands.
According to the United Nations, another 25 tons of cocaine meant for Belgium were seized in expediting countries.
In all, 102 tons of cocaine headed for the European continent were intercepted last year by an international law enforcement project co-implemented by the UN.
