Apple Inc., the world's most valuable company, said proposed U.S. tariffs on $200 billion worth of products imported from China will raise prices for some of its popular consumer goods such as the Apple Watch and AirPods headphones.

The Mac mini desktop computer, Apple Pencil stylus accessory for iPads, various chargers and adapters, and tooling equipment used to manufacturer and design some products in the U.S. will also be affected, the Cupertino, California-based company told the Office of U.S. Trade Representative in a letter dated Sept. 5.

The U.S. has imposed $50 billion worth of tariffs on Chinese goods with another $200 billion in the final stages. The public had until Thursday to comment on the administration's plan. U.S. President Donald Trump said Friday he is considering another $267 billion of tariffs on China, which analysts said will affect virtually every category of consumer goods, to retaliate against what he calls unfair trade practices.
