Illinois

Illinois is where America's manufacturing heartland meets its agricultural breadbasket, and tariffs are squeezing both sides. Caterpillar, John Deere's supply chain, and Abbott Laboratories all depend on Illinois operations that export globally — retaliatory tariffs from China specifically targeted Caterpillar equipment, cutting its Chinese sales. The Chicago area's manufacturing corridor produces everything from candy bars (Mars, Mondelez) to construction equipment to pharmaceuticals, all with globally integrated supply chains. Downstate, Illinois is the #1 soybean-producing state, and China's 25% retaliatory soybean tariff was a body blow that cost Illinois farmers an estimated $1.4 billion in a single year. Corn and pork face similar retaliation. Chicago's role as a transportation and logistics nexus — O'Hare, the nation's rail hub, major interstate interchange — means trade disruption ripples through the state's largest employment sector. The Chicago Mercantile Exchange also suffers from trade uncertainty that increases volatility and reduces agricultural hedging activity. Illinois steel production benefits from import tariffs but faces higher costs for scrap metal and specialty grades.
