In anticipation of its annual conference and in a seemingly cautious move, Apple said today that the tariffs proposed by the US administration of Donald Trump on China will have a significant impact on a number of its products coming.

This comes at a time when there are rumors that the new iPhone set to be announced Wednesday, will not be available to the public at cheap prices as was previously rumored.

The proposed tariffs would impose a 25 percent tax on either the products themselves or on the components they manufacture, raising the price to users and potentially lowering sales as well. Products include watches and earphones from Apple.

Apple's MacBook, Apple's pen, Apple wireless mouse, leather case covers, bags, some chargers and internal components will also be affected by the new tariffs, Apple said in a letter to the US Trade Representative.

The company says the tariff will "appear as a tax to American consumers," so it asks for tariff review and non-tariff coverage.

So far, the United States and China have avoided setting tariffs that could affect key technological products, an area where the two countries' interests are strongly intertwined.

Apple, in particular, was a concern for both countries. Apple's products in the United States made the company one of the richest in the world, but these products were built in China, creating a large number of jobs there.

This round of tariffs was proposed during June and July, as part of President Trump's ongoing dispute with China over its trade practices. The proposal demanded tariffs on Chinese goods worth two hundred billion dollars, and ends the suspension of these tariffs today, Apple submitted its message on Wednesday.

The company says the tariff will leave it in a disadvantage for foreign competitors, and consumers in the United States will be the first to be affected by the law.

It remains unclear when the proposed tariffs will enter into force, or whether there are significant changes or exceptions in the final list. "We will make comments and we will make a decision," White House economic adviser Larry Kudlow said in an interview with Bloomberg television.
