BOISE, Idaho — Tensions between the US and its second-largest trade partner — and Idaho’s top partner — boiled over last month when President Trump lashed out at Canada with a slew of new tariffs. …Canadian officials said last week that they were “targeting” products that would affect certain states as they responded with tariffs of their own. …Idaho exports more goods to its northern neighbor than it does to its next six largest markets — Taiwan, Mexico, Singapore, Japan, China and Malaysia. Agricultural and food products are the state’s top exported goods, and Canada is the biggest market for them. …Wood, paper, pulp and printing products are also on the list of items facing 50% tariffs from both sides. …Idaho imports wood and paper products from Canada more than twice the amount it exports. …Trump’s new round of tariffs is another way to target Canadian wood, which this time affects different types of plywood.
