The rate increase, from 10pc to 25pc, is due to be implemented on Jan 1. Trump's comments to the Wall Street Journal that he may include Apple's signature product in another round of tariffs on Chinese imports are another blow for Chief Executive Officer Tim Cook.
Speaking to the Wall Street Journal, Trump said that the only deal he would take from China would be to open up to U.S. competition.
He also said that he would introduce tariffs on additional goods if the countries do not reach a position that is favourable to the US.
When the WSJ asked if that includes handsets like the iPhone as well as notebook computers, he said "Depends on what the rate is, I can make it 10%, and people could stand that very easily". Trump said the tariff could be anywhere between 10 and 25 percent.
In an interview with The Wall Street Journal, Trump said that it was "highly unlikely" that he would accept Beijing's request not to move forward with increasing tariffs on $US200 billion worth of Chinese goods to 25% from 10%.
Despite using contract manufacturers to make most of its products overseas, Apple has also sought to emphasise its contribution to the U.S. economy, saying it plans to spend about US$55 billion in 2018 with its US-based suppliers. Trump on several occasions has suggested that Apple should bring iPhone manufacturing to the U.S.

Trade-related worries lifted the greenback and the dollar index, which tracks the US dollar versus the euro, yen, sterling and three other currencies, was up 0.21 per cent at 97.281.

The first major casualty of the China-US trade war is getting "back into business, fast" according to the president of the United States.
Apple's stock is down more than 20 percent since November 1, when it gave a lukewarm sales forecast for the upcoming holiday season and said it would stop disclosing how many iPhones it sells every quarter.
Trump is also inked in to meet separately with Russia's Vladimir Putin and the leaders of Argentina, Germany, India, Japan, South Korea and Turkey, White House officials said.
"The upcoming meeting between Trump and Xi is pivotal going into the year-end and for the outlook for global growth, which has shown signs of slowing", said Lee Hardman, a currency analyst at MUFG in London.
