The world champions had sought to overturn the stripping of Ricciardo's second place in Melbourne for breaching fuel flow regulations.
The FIA's International Court of Appeal issued a ruling after a six-hour hearing Monday when other teams had called for the punishmen to be toughened.
Red Bull's rookie Australian driver is left in 10th place in the championship with 12 points, 49 behind Mercedes' pacesetter Nico Rosberg ahead of Sunday's Chinese Grand Prix.
Red Bull are fourth in the constructors' standings on 35 points with Mercedes leading on 111.
