Uncle Mao's supplement has been very comprehensive. To mention a little more, this overthrow of Trump tariff will not negate all tariffs. Article 232 of the Trade Expansion Act of 1962: Tariffs imposed on industries such as steel, aluminum, and automobiles on the grounds of national security remain valid. Article 301 of the Trade Law of 1974: Tariffs imposed on unfair trade practices (such as intellectual property issues in China) remain valid. These two are still valid.
