President Donald Trump said on Tuesday he will announce a 50% tariff on copper later in the day, aiming to boost U.S. production of a metal critical to electric vehicles, military hardware, the power grid and many consumer goods.

President Donald Trump said a new 50% tariff on all copper imports will come Tuesday. However, he did not specify when the new tariff would take effect.

President Donald Trump said he planned to implement a 50% duty on copper imports as part of a set of looming sectoral tariffs, while also indicating he could offer pharmaceutical manufacturers at least a year before applying a crippling 200% tariff on their foreign-made products.
