Workers examine a manufactured component at a factory producing kitchen and bathroom products owned by US manufacturer Sam Miller, whose business has been affected by President Donald Trump's tariffs on imported materials, in Warren, Ohio, on September 30, 2026. Since returning to the presidency in January 2025, Trump has wielded executive powers to swiftly slap tariffs on various products and countries. Besides aluminum, his tariffs hit steel and autos too, while US trading partners face country-specific duties. While some American manufacturers have benefited as their foreign competitors encounter higher barriers, others struggle with ballooning costs and persistent uncertainty.
