The International Trade Commission (ITC) postponed the decision on whether to impose tariffs on US sales of Canada's largest jet, Bombardier, until Friday.
The ITC moved the sentence date from Thursday to Friday due to the recent reservation placed by the US government.
The ITC, which oversees U.S. law and trade, will decide whether to comply with a U.S. Department of Commerce recommendation to impose a nearly 300% duty on CSeries sales which has increased seating from 110 to 130.
The case follows a petition from Boeing, the world's largest airliner manufacturer, which said its business was hurt because Bombardier received illegal government subsidies and dumped the CSeries in the US through the 2016 sale of 75 jets. at "absurdly low prices" for Delta Airlines.
Bombardier, which disputes Boeing's request, made a last-minute request for ITC to consider Brazilian rival Embraer SA's new E190-E2 as a competitor in the 100-150-seat market due to recent range enhancements. new plane.
On Wednesday, the Canadian manufacturer's request was rejected, said Bombardier spokesman Mike Nadolski.
The ITC considered only 100- to 150-seat jets with a range of 2.900 nautical miles or more to be competitors of Boeing's 737 narrowbodies. While the CSeries was included as a competitor, the E190-E2, which will enter service this year and has around 100 seats, was excluded because it had a shorter range.
