Smuggling cigarettes accounted for the bulk of the busted goods, totaling nearly 109 million pieces estimated at more than 38 million litas.
The Customs Service said the largest tobacco smuggling cases were solved in close cooperation with foreign and Lithuanian law-enforcement institutions.
In the framework of an international operation performed after two months of investigation, officers of the Customs Criminal Service and the State Tax Inspectorate in June busted 3,000 boxes of illegal cigarettes estimated at 10 million litas. Another 3,000 boxes were apprehended in Poland and Latvia, with help from colleagues in neighboring states.
Other busted goods include pet clothing, Lithuanian sugar from Latvia, ancient weapons, and anaconda skin, customs said.
The authorities have also observed an increased tendency of sending drugs by mail. Over the first half of 2012, customs officers seized more than 21 kilograms of drugs, with 46 investigations started in connection to the cases.
