The Financial Post reports in its Friday, Aug. 22, edition that there is growing concern about a move by the United States to make hundreds more products subject to the country's 50-per-cent tariffs on steel and aluminum content. A Canadian Press dispatch to the Post reports that the addition of 407 categories, ranging from bulldozers to furniture, came into effect earlier this week to add pressure and costs to those hoping to sell into the U.S. market. Catherine Cobden, head of the Canadian Steel Producers Association, says the move is another blow to the integrated Canada-U.S. economy and will impact the manufacturing of steel-containing products in Canada destined for the U.S. She says products like cutlery, propane tanks, air conditioners, tractors and many more now face the additional tariffs on their metal content. Ms. Cobden said in the statement Thursday that Canada should retaliate with a 50-per-cent tariff on all U.S. steel entering Canada, including ending an April reprieve on U.S. steel used in manufacturing and processing. Hamilton Mayor Andrea Horwath said the "underhanded move to quietly expand U.S. tariffs" is devastating for the city.
