No new date was set for the inspectors' visit. The IAEA, the UN's nuclear watchdog, had no comment.
The postponement came as the IAEA board members continued discussing in Vienna ways to censure Iran for its failure to fully expose its nuclear activities.
Last month, the IAEA accused Iran of hiding evidence of nuclear experiments and noted discovery at Iran's nuclear facilities of a system that could be used to produce weapons.
