Title 19 › Chapter 27— BIPARTISAN CONGRESSIONAL TRADE PRIORITIES AND ACCOUNTABILITY › § 4202
The President can make trade deals and change import duties when he finds that foreign or U.S. tariffs or other import rules are unfairly hurting U.S. trade and the deals will help the goals of this law. He may enter such agreements before July 1, 2018, or before July 1, 2021 if the special congressional trade rules are extended under subsection (c). The President must tell Congress before starting a deal. He can order changes to duties, keep duty-free or excise treatment, or add duties, but there are limits: he cannot cut a duty below half of the rate that applied on June 29, 2015 (except for duties that were 5 percent ad valorem or less on that date), cannot cut import-sensitive farm product rates below the Uruguay Round level, and cannot raise any duty above its June 29, 2015 level. Duty cuts under a deal usually must be phased in each year (each year at least a 3 percent ad valorem cut or one-tenth of the total cut, whichever is larger), unless the product is not made in the United States (the U.S. International Trade Commission will advise which ones). The President may round annual cuts slightly (up to 0.5 percent ad valorem). Any cut barred by those limits can only take effect if included in an implementing bill that becomes law. Changes agreed under WTO Schedule XX may be made despite some of these limits, with required consultation. The President may also make agreements to remove or limit duties, restrictions, or other trade barriers that harm or could harm the U.S. economy. Such agreements must make progress toward the law’s objectives and meet the conditions in other parts of the law. Bills to approve them use the trade authorities procedures and may only include approval and the legal changes strictly needed. To extend those procedures from July 1, 2018 to July 1, 2021, the President had to send Congress a written request by April 1, 2018 with details; the Advisory Committee and the U.S. International Trade Commission must give reports by June 1, 2018. Congress can pass a special disapproval resolution but cannot act on it after June 30, 2018. The President must also start timely negotiations to reduce barriers in many sectors (for example, agriculture, services, technology, medical equipment, civil aircraft, and infrastructure) when it would benefit the United States.
