Undeclared canned soft drinks were seized by the customs department last week when they were found in a container.
The customs said enforcement officers were inspecting a container carrying three used cars imported from the UK. The vehicles were declared to customs.
But apart from the cars, 255 cartons of canned soft drinks, each containing 24 330ml cans, were found. They were not covered by an import licence.
The 6,120 cans were confiscated.
