President Donald Trump’s new 50% tariffs on certain Canadian goods could harm St. Louis and Missouri by raising manufacturing costs, disrupting cross-border supply chains and exposing some Missouri exports to retaliatory tariffs Canada plans to impose Sept. 8.
Canada is Missouri’s largest export market. In 2025, the state shipped $5.8 billion in goods to Canada, about 31% of all Missouri exports.
Overall, Missouri exported $18.7 billion in goods worldwide in 2025. The state’s goods exports supported an estimated 74,000 jobs in 2023, the latest year for which employment data are available.
Small and medium-sized businesses accounted for 84% of Missouri companies exporting goods in 2023, meaning trade disruptions can affect businesses beyond the state’s largest corporations. Tariffs also could raise costs for businesses that rely on Canadian products, costs that may ultimately be passed along to consumers.
