According to the Foreign Ministry, the 25 percent tariff will apply to some cheeses and a part of pork products, but most cheeses will not be subject to the additional duty.
"The majority of Lithuanian cheese products exported to the US is not on the US list of Lithuanian goods subject to tariffs," the ministry told BNS.
"The additional 25 percent customs tariffs will apply to 1.8 million US dollars’ worth of Lithuanian exports – some cheeses and some pork products. In total, about 0.12 percent of Lithuania's exports to the US will be affected," it said.
The ministry gives no details as to which companies will be affected by the new tariffs.
According to figures from Enterprise Lithuania, the government's export promotion agency, Lithuania's dairy exports to the US totaled 9 million euros last year.
The tariffs took effect last Friday after last-minute talks between European officials and US trade representatives ended without agreement.
