August 1st, 2019 – President Trump announced via twitter that the remaining $300 billion of Chinese goods would be subject to an additional 10% tariff. List 4 is on the horizon (September 1st).
Trump could call off the potential tariffs, such as the announced 5% tariff on Mexican imports. However, there is a greater chance the President will go through with his word here, given his history of imposing tariffs on China.
As of August 1st, the President or the U.S. Trade Representative have yet to publish an official order. The proposed list of goods on List 4 can be found here.
