President Trump’s tariffs on imported steel and aluminum went into effect on Wednesday, intensifying America’s trade conflicts with global competitors and causing concern among U.S. allies. According to industry insiders, the imposition of the tariffs is expected to increase costs for American manufacturers of cars, tin cans, solar panels, and other products, which could slow down the wider U.S. economy. Costs for domestic steel firms increased, while Tariffs resulted in higher production costs for firms making automobiles, tools, and industrial machinery, lowering production in those and other downstream businesses due to increased metal costs.
