Steel and aluminum tariffs imposed on imports

On March 8, 2018, President Trump signed Proclamation 9705 imposing a 25% tariff on steel imports and a 10% tariff on aluminum imports, with limited exemptions for Canada and Mexico. The tariffs applied to all steel and aluminum products entering the United States from nearly all countries. American manufacturers, consumers, and industries relying on steel and aluminum imports faced increased material costs, which were passed through supply chains affecting vehicle prices, construction materials, appliances, and consumer goods.
