Following Donald Trump’s imposition of 25% tariffs on Canada and Mexico, as well as retaliatory tariffs from Canada, trade across North America’s borders has suddenly become much more expensive.

This map shows how much different U.S. states’ trade is impacted by these tariffs, by visualizing each state’s combined share of imports from Mexico and Canada in 2024. The visualization uses data from the U.S. International Trade Administration.

Canada and Mexican Trade Partners

Canada and Mexico made up 28% of U.S. goods imports overall in 2024, but some states have a much higher or lower share of their imports coming from the country’s northern and southern neighbors.

The state of Montana is leading the pack at 93%. Following Montana in terms of import dependence on Canada and Mexico are Maine (72%), Vermont (71%), and North Dakota (71%), all states which share their northern border with Canada.

Montana’s high import dependence is almost entirely on Canada, which alone makes up 92% of the state’s imports. The Treasure State’s shared border with the province of Alberta and its three oil refineries makes it a perfect importer for Canadian crude oil. 76% of Montana’s imports from Canada were oil and gas.

Looking at southern states dependent on Canadian and Mexican trade, Texas (49%) and Oklahoma (56%) stand out. Despite being much closer to the southern border, Oklahoma is a similar case to Montana, with 50% of the state’s imports coming only from Canada and 79% of those imports being oil and gas.

Texas (the second-largest state economy in the U.S.) is instead much more dependent on imports from Mexico, which make up 40% of the state’s imports overall. The top goods Texas imported from Mexico in 2024 were motor vehicles and their parts at 23%, followed by computer equipment at 22%.
