On December 14, 2018, the Office of the United States Trade Representative announced that they would be postponing the date on which the rate of additional duties would increase to 25% for the products covered under the third phase of Section 301 tariffs covering $200 billion worth of goods currently subject to 10% tariffs.

Duties on this list of products were previously set to increase to 25% on January 1, 2019, but as a result of ongoing trade negotiations with China, this date has now been postponed to March 2, 2019. This is one day after the 90-day period the President agreed upon with Chinese President Xi Jinping on December 1, 2018. Should the countries fail to come to an agreement by the March 1, 2019 deadline, the higher 25% tariff will go into effect.
