The warning, delivered via Trump’s Truth Social account, puts additional pressure on Apple as it continues shifting production out of China to mitigate previous tariffs and diversify its supply chain.

President Donald Trump on Friday escalated tensions with one of America’s most iconic technology companies, threatening to impose a 25% import tariff on Apple products unless iPhones are manufactured domestically.

The warning, delivered via Trump’s Truth Social account, puts additional pressure on Apple as it continues shifting production out of China to mitigate previous tariffs and diversify its supply chain.

“I have long ago informed Tim Cook of Apple that I expect their iPhones that will be sold in the United  States of America will be manufactured and built in the United States, not India, or anyplace else,” Trump wrote.

“If that is not the case, a Tariff of at least 25% must be paid by Apple to the U.S.”

The proposed tariff could significantly raise the cost of iPhones in the U.S. market, potentially affecting sales and profitability for Apple, which remains one of the most valuable companies in the world.

Apple has not publicly responded to the latest threat.

The threat is part of a broader pattern of Trump’s economic nationalism, which includes imposing or threatening import duties on foreign-manufactured goods to encourage domestic production.

Over the past year, Trump has openly criticised corporate giants, including Amazon and Walmart, for what he describes as practices that undermine American workers and contribute to inflation.

Apple has been gradually shifting portions of its iPhone assembly to India, particularly in response to the Trump administration’s earlier tariffs on Chinese imports during his first term.

Apple CEO Tim Cook has previously met with Trump and other White House officials to shield Apple from the fallout of the U.S.-China trade war.

Nonetheless, the company’s efforts to adapt its global supply chain have repeatedly drawn Trump’s ire.

During a recent trip to the Middle East, Trump again expressed frustration over Apple’s offshore manufacturing, sources say, reiterating his desire to see high-tech jobs return to American soil.

The potential tariff threat places Apple in an increasingly difficult position.

While the company has invested in some U.S.-based facilities and suppliers, the bulk of its assembly operations, particularly for the iPhone, remain overseas due to logistical, labour, and cost efficiencies.
