Kumara was fined 25% of his match fee while Das lost 15% for the incident, which occurred during the fifth over of Bangladesh's innings, the governing body said on Monday.
The Sri Lankan fast bowler walked towards Das after dismissing him, provoking an aggressive reaction from the batter. They had to be separated by the umpires and other players.
Both players accepted the proposed sanctions, the ICC said.
Sri Lanka won the match by five wickets.
