The "Undertaking Negotiations on Investment and Trade for Economic Dynamism Act," or the UNITED Act, expresses a strong Sense of Congress that the United States should pursue more open trade and investment relationships with its allies, particularly the United Kingdom. Congress believes a high-standard, comprehensive trade agreement would strengthen the relationship, improve economic prospects, increase supply chain resilience, and support collaboration in emerging technologies. The bill acknowledges previous bilateral efforts and emphasizes that any agreement must build on USMCA standards and honor the Good Friday Agreement , ensuring peace and stability in Ireland and Northern Ireland. This Act grants the President specific authority to initiate and enter into a comprehensive trade agreement with the United Kingdom. The President is mandated to begin negotiations within 180 days of the Act's enactment, focusing on tariff and non-tariff barriers affecting various sectors. This authority to enter into an agreement will terminate on March 1, 2029 . While the President may proclaim modifications to existing duties to implement the agreement, there are limitations, such as not reducing duties below 50 percent of the current rate for duties over 5 percent, and not reducing duties on import-sensitive agricultural products below Uruguay Round levels. To ensure alignment with congressional priorities, the President must consult with Congress throughout the negotiation process and notify them of the intent to enter into an agreement. Implementing bills for any such trade agreement will qualify for trade authorities procedures , commonly known as fast-track authority, under the Trade Act of 1974. Furthermore, the agreement and its implementing legislation must adhere to the comprehensive requirements of the Bipartisan Congressional Trade Priorities and Accountability Act of 2015, including negotiating objectives and oversight provisions. The bill also stipulates that the agreement cannot be waived, suspended, or terminated without express congressional approval.
