U.S. escalates China trade showdown with tariffs on $50 billion in imports.

WASHINGTON (Reuters) - The Trump administration on Tuesday raised the stakes in a growing trade showdown with China, announcing 25 percent tariffs on some 1,300 industrial technology, transport and medical products to try to force changes in Beijing's intellectual property practices.

The U.S. Trade Representative's office unveiled a list of mainly non-consumer products representing about $50 billion of estimated 2018 imports that would nonetheless hit supply chains for many U.S. manufacturers. The list ranges from chemicals to TV sets, motor vehicles and electronic components.

Publication of the tariff lists starts a public comment and consultation period expected to last around two months, after which USTR said it would issue a "final determination" on the product list. It has scheduled a May 15 public hearing on the tariffs.
