On March 4, President Trump increased tariffs on Chinese goods to 20% and imposed 25% tariffs on Mexican and Canadian imports (with a lower 10% rate for Canadian energy imports). Later that week, he granted a reprieve to automakers, then paused tariffs on imports that fall under the United States-Mexico-Canada Agreement (USMCA) until April 2. USMCA applies to around half of Mexico’s imports and 38% of Canada’s.
In 2024, Canada, Mexico and China accounted for over $1.35 trillion, or 41.5% of all U.S. imports. China and Canada have announced retaliatory tariffs.
Key construction imports from China include electrical and lighting equipment, HVAC equipment, appliances and hardware. From Mexico, the construction industry imports appliances, HVAC equipment, switchgear and steel, while Canada is a source of iron and steel, aluminum and wood products. Of these, the industry is particularly reliant on imports of aluminum, appliances, power tools, switchgear and hardware.
On March 12, Trump instituted 25% tariffs on steel and aluminum imports from all countries. The U.S. imports around $61 billion in steel and aluminum yearly, and both metals are important for construction.
Prices for steel have already increased ahead of the tariffs, though most steel used in the U.S. is produced domestically. Imports accounted for 23% of all steel used in the country last year. In 2018-2019, steel prices initially rose after tariffs were enacted, but prices fell as domestic production responded. The U.S. steel industry has additional production capacity, with raw steel production operating at 74% of capacity so far this year. Additionally, several new plants and expansions are set to come online in 2025.
The U.S is more reliant on imports for aluminum, primarily from Canada. S&P Global notes that a small supply surplus in 2025 leaves prices vulnerable to disruptions. Global aluminum prices are heavily impacted by China, which is the largest producer and consumer of the metal.
Reciprocal tariffs, which could apply to a wide range of countries and goods, are also planned for April 2.
