Apple warns President Donald Trump's proposed tariffs on China will lead to a price increase on many of its most popular products.

In a letter addressed to the Office of U.S. Trade Representative, the Cupertino company said: "It is difficult to see how tariffs that hurt US companies and US consumers will advance the government’s objectives with respect to China’s technology policies.

"We hope, instead, that you will reconsider these measures and work to find other, more effective solutions that leave the U.S. economy and U.S. consumer stronger and healthier than ever before."

Apple continued that the tariff list “covers a wide range of Apple products and the products used in our U.S. operations.” These include the Mac Mini, Apple power adapters, cables, the Apple Watch, the Apple Pencil, and Air Pods.

Notably, Apple did not cite the iPhone as a product which may be impacted. Following meetings with the Trump administration earlier this year, Apple CEO Tim Cook stated that he was confident tariffs would not affect the device. The iPhone is Apple's primary revenue driver.
