Border force have confiscated 6,000 litres of Nigerian spirits– which would have cost the Government more than £68,000 in lost revenue – at the port of Tilbury.
The contraband alcohol had been split between two containers shipped to the UK from Nigeria.
One container, which was searched on July 19, contained 3,300 litres of 42 per cent proof bitters and the other, searched on July 22, contained 2,699.25 litres of the same product.
In an attempt to evade excise duty on the alcohol, the smugglers responsible had listed the contents of the containers as foodstuffs.
In a further attempt to conceal the true nature of the contents of one of the containers the spirits had been placed inside boxes labelled as containing soft drinks.
Had the smuggling attempt proved successful it could have cost the Treasury approximately £68,800 in unpaid duty.
No arrests have yet been made.
Mark Kennedy, Border Force Assistant Director at Tilbury, said: "This was an excellent detection.
"By stopping the shipment we have starved those responsible of the proceeds of their criminality.
"We will continue to work hard to tackle criminals out to make a profit by cheating British tax payers and undercutting honest local traders."
They use an array of search techniques including sniffer dogs, carbon dioxide detectors, heartbeat monitors and scanners - as well as visual searches - to find well-hidden stowaways, illegal drugs, firearms and tobacco which would otherwise end up causing harm to local people, businesses and communities.
