Trump's Visit to Apple Factory Brings Possibility of More Tariff Relief Michelle Quinn SAN FRANCISCO - President Donald Trump's visit this week to a Texas manufacturing plant highlights the ongoing dance between the iPhone maker and the Trump administration over China and tariffs. The visit came as the U.S. is set Dec. 15 to raise new tariffs on imports from China, as part of its trade war with Beijing. Among U.S. technology companies, Apple has much at risk since many of its products, including the iPhone, Apple Watch and the iPad, are made in China. Two economies The economies of China and Silicon Valley are knitted together in complicated ways. Chinese factories make Apple products from components that come from the U.S. But Chinese factories also make some of the components for Apple's Mac Pro, which has been made in the U.S. for years. The trade war between Washington and Beijing has put pressure on these cross-border supply chains. In July, Trump said no to Apple's request for tariff waivers. Apple will not be given Tariff waiver, or relief, for Mac Pro parts that are made in China. Make them in the USA, no Tariffs! -- Donald J. Trump (@realDonaldTrump) [1]July 26, 2019 But in September, the administration granted 10 waivers for those parts. In response, Apple said its Mac Pro would continue to be made in Texas by a firm called Flex. "I think the conversation about perhaps exempting Apple from these tariffs is a recognition that in fact that tariffs can differentially impact in a negative way various U.S. companies," Sean Randolph, senior director at the Bay Area Council Economic Institute, said. "And if it's a flagship company like Apple with a global brand, that becomes an issue."
