Donald Trump threatened Apple with a 25% tariff on iPhones sold in the US unless production shifts from India to the US. Trump's statement followed Apple's plans to source iPhones from India to avoid existing tariffs on Chinese-made goods. Apple's stock fell 3% after the threat. Trump previously claimed Apple would increase US production, but Apple cited diversification of its supply chain to mitigate risk. The threat escalates the ongoing trade tensions and highlights the challenges of reshoring complex manufacturing.
