Apple\u2019s suppliers will consider shifting iPhone production away from China should tariffs on US imports skyrocket, but the US company plans to sit tight for now, people familiar with the company\u2019s thinking said. The tech giant\u2019s suppliers intend to stick with the existing model even if the US levies a 10% import tariff on smartphones, the people said, asking not to be identified talking about a private matter. But it will have to reassess the situation should US President Donald Trump decide on a more punitive 25%, the people said. iPhones \u2014 the majority of which are made by assembly partner Hon Hai Precision Industry in China and shipped around the world \u2014 have so far been spared in a tit-for-tat trade war between the world\u2019s two largest economies. But Trump told the Wall Street Journal last month that tariffs could be slapped on smartphones and laptops made in China, the world\u2019s largest manufacturer of electronics. Apple has long used the world\u2019s No. 2 economy as its production base for everything from its signature device to iPads and Macs. The company\u2019s supply chain now spans hundreds of companies, culminating in assemblers such as Hon Hai and Pegatron. Apple wasn\u2019t available for comment outside of US business hours. Hon Hai and Pegatron declined to comment. Apple\u2019s manufacturing partners are largely beholden to the US company\u2019s wishes. Migrating parts of the sprawling network they underpin will be difficult and the US company seems to be in wait-and-see mode for now, one of the people said. An Apple partner has already suggested alternative locations for non-iPhone production, but the US company has indicated there\u2019s little need to make such a move for now, another person said. That may change if tariffs escalate, an outcome now in the balance as Washington and Beijing begin thorny negotiations on a trade deal that could scale back a series of tariffs implemented this year. Apple, already grappling with mounting evidence that its latest iPhone line-up has failed to excite consumers, can ill-afford a sharp hike in import taxes. A 10% tariff could result in an earnings-per-share decline of just $1 for Apple, should all its hardware sold in the US be subject to the levy and the company absorbs the cost, RBC analyst Amit Daryanani wrote in a November 28 research note. That compares with the average 2019 Apple-EPS estimate of $13.32, according to data compiled by Bloomberg. However, a more severe scenario of a 25% tariff \u2014 absorbed by Apple \u2014 could result in an EPS decline of about $2.50, he added.

However, in recent months, he has modified that view, saying in an interview this year that \u201cit\u2019s not true that the iPhone is not made in the United States.\u201d Some components, like the smartphone\u2019s glass cover, are manufactured in the US and shipped for assembly in China.
