The Scottish champions were reprimanded by European football's governing body after flares were set off and fans clashed with police in the away end during their visit to Croatia on Dec. 11.
UEFA's Control, Ethics and Disciplinary Body announced the fine as Celtic travel to Italy for the second leg of their last 32 tie against Inter Milan on Thursday.
It is the fifth time in three years that the Scottish club have been charged due to the behaviour of their supporters during matches in Europe.
