Trump said on Friday evening that the punitive tariffs will come into effect from "the end of June", and that it concerns the entire mobile phone industry.
It would also include Samsung and all others who manufacture the product, otherwise it would not be fair, he says.
The announcement comes hours after he warned Apple of punitive tariffs, since they do not manufacture their phones in the USA.
"I have long since informed Tim Cook (Apple's CEO) that I expect their iPhone to be sold in the USA to be manufactured and assembled in the USA, not in India, or any other place", Trump wrote on his platform Truth Social.
Apple – valued at around 3,000 billion dollars on Wall Street – has recently become a frequent target in Donald Trump's campaign to get multinational corporations to move manufacturing jobs to the USA.
Apple has the majority of its iPhone production in China, where a network of subcontractors has been built up over many years. The IT giant does not manufacture any mobile phones at all in the USA.
In response to Trump's attacks, Apple has promised more jobs in the USA and flagged massive investments over the next four years.
Apple is one of the biggest losers on Wall Street this year, with a price drop of around 20 percent since the turn of the year.
