The Trump administration is planning to put tariffs on some of the country’s — and Maine’s — biggest trade partners.

A 10% tax on Canadian energy imports and a steeper 25% tax on all other goods from the country is expected to go into effect Tuesday. Goods from Mexico would also be hit with 25% tariffs.

The move comes about a month after President Donald Trump postponed his initial tariff threats against the United States’ neighbors at the last minute.

Meanwhile, a 10% levy on all imports from China that did go into effect last month will rise to 20% Tuesday.

The tariffs are intended to protect American industries and pressure countries to negotiate on key issues such as border security. But they threaten to trigger a trade war that will strain U.S. businesses with operations in those countries and drive up the prices American consumers pay for various products.

Maine is more reliant on Canada than the rest of the U.S., with over 70% of the state’s imports last year coming from its northern neighbor compared to 13.5% nationally.

Maine brought in $4.4 billion of goods from Canada in 2024, the vast majority being fuel and oil, with wood pulp and wood products like lumber next on the list, according to data from the U.S. Department of Commerce.

Maine is less reliant on China and Mexico, which accounted for 2.7% and 1.3% of the state’s imports in 2024, respectively, compared to 13.5% and 15.6% of all U.S. imports.

Still, China has been Maine’s second biggest trading partner for all but one of the last 10 years (the exception was 2023, when Germany topped China). The total value of imports from China has dropped substantially during that period, from $466.8 million in 2015 to $164.6 million last year.

Mexico, the No. 1 trade partner of the U.S. as of 2023, is lower down on Maine’s list but still consistently in the state’s top 10. A total of $77.8 million worth of footwear, machinery, textiles and other goods came to Maine from Mexico last year.
