Pennsylvania

Pennsylvania's diverse industrial economy creates tariff exposure from the steel mills of Pittsburgh to the pharmaceutical labs of the Philadelphia suburbs. US Steel's historic Mon Valley Works and Cleveland-Cliffs' operations benefit from 25% steel tariffs, but these gains come at the expense of far larger downstream industries — auto parts, machinery, and construction — that pay more for steel inputs. Philadelphia's pharmaceutical corridor (GSK, AstraZeneca legacy operations, Merck facilities, numerous biotechs) imports APIs and exports finished drugs in a globally integrated supply chain now disrupted at both ends. The state's chemical industry along the Delaware River faces tariffs on imported feedstocks while retaliatory measures threaten specialty chemical exports. Pennsylvania is America's #1 mushroom producer (60% of US production in Chester County) and mushrooms face retaliatory tariffs. The state's diverse agriculture — dairy, soybeans, hay — faces retaliation across multiple product categories. Natural gas from the Marcellus Shale has made Pennsylvania a top energy producer, and while LNG exports face less direct tariff threat, equipment tariffs raise extraction costs. Hershey and other food manufacturers face higher costs on imported cocoa, sugar, and ingredients.
