Barcelona were fined €25,000 ($26,600) by UEFA on Thursday for Nazi salutes and racist gestures by fans at a Champions League game against Paris Saint-Germain last week.
UEFA said the proven charge of "racist behavior" followed images circulating of misconduct by some fans at Parc des Princes on April 10.
UEFA also deferred a one-game ban on selling tickets to Barcelona fans for an away game in the Champions League next season for a probationary period of one year.
Barcelona also were ordered to compensate PSG for damage to seats by fans and pay additional fines totaling €7,000 ($7,500).
Barcelona won 3-2 in Paris in the first leg of the quarterfinals but were eliminated Tuesday after losing 4-1 in the home leg.
World football body FIFA is set to launch a new drive against racism next month at its annual congress meeting, being held in Bangkok, Thailand.
