Indiana

Indiana is America's most manufacturing-intensive state by share of GDP, making it disproportionately exposed to tariff disruption. The state hosts Subaru's only US plant (Lafayette), Toyota's largest US truck factory (Princeton), GM assembly, and Honda operations — the 25% auto tariff on imported parts raises costs across every one of these plants, even though they assemble vehicles domestically. Eli Lilly, headquartered in Indianapolis, is Indiana's largest company and a major pharmaceutical exporter now navigating retaliatory threats on drug exports and tariffs on imported active ingredients. The Cummins engine plant in Columbus exports diesel engines worldwide and faces retaliatory tariffs from China and the EU. Indiana's RV industry — centered in Elkhart, producing 80% of US recreational vehicles — depends on imported steel, aluminum, and components that are all more expensive under tariffs. Agriculture anchors southern and central Indiana: the state is a top-5 soybean and corn producer, both prime retaliation targets. Steel production in Gary and the northwest corner benefits from import tariffs, creating a rare in-state winner-loser divide.
