Trump also said he would soon announce tariffs “at a very, very high rate, like 200%,” on pharmaceutical imports.

U.S. President Donald Trump broadened his global trade war on Tuesday as he announced a 50% tariff on imported copper and said long-threatened levies on semiconductors and pharmaceuticals were coming soon.

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.
