In addition to the original NAFTA provisions, the USMCA borrows significant credits under the Trans-Pacific Partnership (TPP) trade agreements and the Comprehensive and Progressive Agreement for the Trans-Pacific Partnership (CPTPP). On April 3, 2020, Mexico announced its willingness to implement the agreement and joined Canada.  The agreement came into force on July 1, 2020.     The U.S. Department of Commerce (www.trade.gov/export-solutions) May 27, Robert E. Lighthizer, U.S. Trade Representative, presented to Congress a draft statement on the administrative measures needed to implement the U.S.-Mexico agreement (USMCA and the new NAFTA), in accordance with the 2015 President of Commerce`s Administrative Action Declaration (TPA). The project will allow congress to be presented to Congress, after 30 days, on June 29, a law to implement the USMCA. In a letter  to Nancy Pelosi, House of Representatives spokeswoman, and Kevin McCarthy, the minority leader of the House of Representatives, the Republican, told Lighthizer that the USMCA was the gold standard in U.S.
trade policy, modernizing the competitive trade in digital, intellectual property and services in the United States, and creating a level playing field for U.S. businesses, workers and farmers, an agreement that represents a fundamental shift in trade relations between Mexico and Mexico. To facilitate the strengthening of cross-border trade, the United States has reached an agreement with Mexico and Canada to increase the value of de minimis delivery. For the first time in decades, Canada will increase its de minimis level from $20 ($15.38) to $40 ($30.77) for taxes. Canada will also offer duty-free shipments of up to 150 $US ($115.38). Mexico will continue to provide $50 de minimis exemptions and will also offer duty-free shipments of up to $117. Shipping rates to this level would be achieved with minimum formal entry procedures, which would allow more businesses, particularly small and medium-sized enterprises, to be part of cross-border trade. Canada will also allow the importer to pay taxes 90 days after the importer enters. The text of the North American agreement on cooperation between workers is available on the website of the Commission for Employment Cooperation. On June 19, 2019, the Mexican Senate ratified the agreement (114 yes, 3 no, 3 abstentions).
 Mexico`s ratification process will be completed when the President announces its ratification to the Federal Register. In addition, there is a provision that the agreement itself must be reviewed every six years by the three nations, with a 16-year forfeiture clause. The contract may be renewed for a period of 16 years during the six-year review period.  The introduction of the Sunset clause gives more control in the organization of the future of the USMCA in the hands of national governments.
