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.

Copper entering the US from other countries is set to face a new tax of 50%, President Donald Trump has said. The decision carries through on tariff threats he made earlier this year, when he ordered an investigation into how imports of the metal were affecting national security.

WASHINGTON (Reuters) -President Donald Trump said he will announce a 50% tariff on imported copper on Tuesday, an effort to boost U.S. production of a metal critical to electric vehicles, military hardware, the power grid and many consumer goods. U.S. Comex copper futures jumped more than 10% after the announcement.
