“We’ll be putting (an) initially small tariff on pharmaceuticals, but in one year, one-and-a-half years, maximum, it’s going to go to 150%,” Trump said in an interview on CNBC.

“And then it’s going to go to 250% because we want pharmaceuticals made in our country,” he added.

In the same interview, Trump said he expects to raise the US tariff on Indian imports “very substantially over the next 24 hours” due to the country’s purchases of Russian oil.

While Trump has taken aim at products from different countries with varying tariff rates after imposing a 10% levy on almost all trading partners in April, these have excluded certain products he planned to target separately.

These sector-specific tariffs have generally come after government investigations that look into the national security concerns surrounding certain imports.

After earlier embarking on probes on imported semiconductors and pharmaceuticals, the Trump administration has signalled plans to wrap up these studies, which could lead to new tariffs.

Already, Trump has slapped steep tariffs of 50% on imported steel and aluminium and also rolled out a separate but lower duty on autos and parts.
