IranAir has ordered 200 passenger aircraft worth $38.3 billion at list prices, including 100 from Airbus <AIR.PA>, 80 from Boeing and 20 from Franco-Italian turboprop maker ATR <LDOF.MI>. All the deals are dependent on U.S. licences because of the heavy use of U.S. parts in commercial planes.
The US Treasury Department said the United States will revoke authorisations for the export of commercial passenger aircraft, parts and services to Iran after a 90-day period.
"As we have throughout this process, we'll continue to follow the U.S. government's lead," Boeing spokesman Gordon Johndroe said.
Boeing Chief Executive Dennis Muilenburg said last month that the airplane manufacturer has no Iranian deliveries scheduled this year. He said Boeing's 777 production plan "is not dependent on the Iranian orders." Muilenburg is set to address the Economic Club of Washington on Wednesday.
European planemaker Airbus said on Tuesday it will study Trump's decision, adding that it would take some time.
