Uefa has charged Celtic with "the displaying of an offensive banner and setting off of fireworks by fans" during Thursday's match with Udinese.
The incidents during the Europa League Group I match were included in the match delegate's report.
Uefa's Control and Disciplinary Body will hear the case on 26 January.
Celtic have already imposed a lifetime ban on the fan they say was responsible for the banner and assaulting a steward at the Stadio Friuli.
Last week, Celtic decided not to appeal against the £12,700 Uefa fine for "illicit chanting" by some of their fans in the earlier Group I game against Rennes at Celtic Park.
