The ICC's enforced its stance after Wednesday's meeting of national chief executives, which came on the same day the IPL held its players' auction.
Almost US$42 million (29 million) was bid at the auction, illustrating the financial clout of the competition that begins in April. However the ICC was not ready to enshrine the league in an international calendar already crammed with fixtures.
The ICC said that the Indian cricket had not made any request for an IPL window, even though there was speculation about possible realignment of the 10-year Future Tours Program (FTP).
"There has been media speculation about creating a window within the Future Tours Program for IPL matches," ICC chief executive Malcolm Speed said. "The FTP is in place until 2012 and there was no suggestion by the Board of Control for Cricket in India (BCCI) that such a window should be considered or created prior to that.
"The other ICC members are supportive of the Indian board and will carefully evaluate the first year of the IPL and its wider impact on the game in other parts of the world."
The ICC said the Indian board had reaffirmed that international tours would always take priority over the IPL.
Foreign players wanting to play in the Indian league require "no-objection certificates" from their respective national boards.
