The Globe and Mail reports in its Friday edition that the U.S. Department of Commerce has imposed final tariffs averaging 20.83 per cent against most Canadian shipments of softwood lumber into the United States. The Globe's Adrian Morrow and Brent Jang write that the weighted average tariffs levied by the Trump administration consist of 14.25 per cent for countervailing duties and 6.58 per cent for anti-dumping levies. The move comes amid deadlocked talks to overhaul the North American free-trade agreement, adding one more strain to the already tense relationship between Ottawa and the Trump administration. The long-running softwood fight factors into one of the most controversial elements of the bilateral agreement -- NAFTA's Chapter 19, which sets up trade panels to settle disputes, including for softwood. Last week, West Fraser Timber chief executive officer Ted Seraphim said that the lack of progress in renegotiating NAFTA paints a gloomy outlook for reaching a separate softwood deal any time soon. West Fraser now faces a combined duty of 23.76 per cent, Montreal-based Resolute Forest Products 17.90 per cent and New Brunswick-based J.D. Irving 9.92 per cent.
