In a result that was shocking to most, on Friday, January 26, 2018, the International Trade Commission announced a finding of NO material injury to American industry (read Boeing) and so voted to NOT impose either antidumping or countervailing duty on Bombardier’s 100 to 150 seat jets. This brings to an end a very high profile trade dispute between the two countries, while many others still remain. No telling how this decision will, if at all, affect the on-going NAFTA renegotiations.
The actual report detailing the findings of the Commissioners is due to be released no later than March 2, 2018. See https://www.usitc.gov/press_room/news_release/2018/er0126ll898.htm for a link to where the report will be posted.
