Title 19 › Chapter CHAPTER 27— - BIPARTISAN CONGRESSIONAL TRADE PRIORITIES AND ACCOUNTABILITY › § 4202
The President can make trade deals and change import duties when he finds that other countries’ or U.S. import rules are unfairly hurting U.S. trade and a deal would help the goals of this law. The President must tell Congress before starting a deal. He may set new duty rates or continue duty-free treatment, but there are firm limits: no duty can be cut below half of the rate that applied on June 29, 2015 (except for duties that were 5% or less on that date), duty on sensitive farm products can’t be cut below the Uruguay Round level, and no duty can be raised above the June 29, 2015 rate. Duty cuts must usually be phased in each year using an initial step equal to the greater of 3% ad valorem or one-tenth of the total cut, repeated yearly. Goods not made in the U.S. can skip the staged steps (the U.S. International Trade Commission will identify them). The President may round yearly cuts by up to either the gap to the next lower whole number or 0.5% ad valorem, whichever is smaller. Any duty cut that would violate the limits above can only take effect if Congress passes an implementing bill that includes that cut. The President may also make agreements to remove or limit trade barriers that burden or likely will burden U.S. trade. Agreements must advance the objectives in section 4201 and meet conditions in sections 4203 and 4204. If a deal needs changes to U.S. law, Congress must receive an implementing bill that follows the special trade rules and only includes the legal changes strictly necessary. The special trade rules apply to deals entered before July 1, 2018, and can be extended to deals entered after June 30, 2018 and before July 1, 2021 only if the President requests the extension by April 1, 2018 and Congress does not adopt a disapproval before July 1, 2018. The President must tell certain advisory bodies and they must report to Congress by June 1, 2018. The President must also start or expand negotiations in many sectors (for example, agriculture, services, intellectual property, industrial and capital goods, procurement, information technology, environmental and medical technology, aircraft, and infrastructure) when doing so is feasible and would help the U.S.
