Contact the Import Specialist team at his center of excellence assigned in www.cbp.gov/trade/centers-excellence-and-expertise-information/cee-directory During his 2016 election campaign and presidency, Trump was highly critical of NAFTA (it was often called “perhaps the worst trade deal of all time” while he hailed the USMCA as “an excellent deal for all of us.”  However, the USMCA is very similar to nafta, has adopted many identical provisions and has made only modest changes, mostly cosmetic, and is expected to have only a limited economic impact.  Former U.S. Trade Representative Mickey Kantor, who oversaw the signing of NAFTA during Bill Clinton`s administration, said, “This is really NAFTA of origin.”  Motor vehicle rules of origin (ROOs) require that a certain portion of the value of an automobile originate in the regulated area. In NAFTA, the required proportion was 62.5%. The USMCA increases this requirement by 12.5 percentage points to 75 per cent of automotive value. The Trump administration`s initial proposal was to increase to 85 percent and an additional provision that 50 percent of auto content is made by U.S. automakers.  Although the text of the agreement did not contain the most sophisticated version of this provision, there is concern that increased domestic purchases, aimed at promoting employment in the United States, could lead to higher input costs and disruptions to existing supply chains.  In addition to the provisions of the original NAFTA, 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.     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. The United States, Mexico and Canada updated NAFTA to create the new USMCA. The USMCA is mutually beneficial to workers, farmers, farmers and businesses in North America. The new agreement, which came into effect on July 1, 2020, will create a more balanced trading environment, support high-paying jobs for Americans and allow the North American economy to grow. The negotiations focused “primarily on car exports, tariffs on steel and aluminum, as well as the milk, egg and poultry markets.” A provision “prevents any party from enacting laws that restrict the cross-border flow of data.”  Compared to NAFTA, the USMCA increases environmental and labour standards and encourages domestic production of cars and trucks.  The agreement also provides up-to-date intellectual property protection, gives the U.S.
more access to the Canadian milk market, imposes a quota for Canadian and Mexican auto production, and increases the customs limit for Canadians who purchase U.S. products online from $20 to $150.  The full list of differences between USMCA and ALEFTA is listed on the Website of the United States Trade Representative (USTR).  Signed on the sidelines of the G20 of Heads of State and Government in November 2018 in Buenos Aires, the CUSMA results preserve key elements of long-term trade relations and contain new and updated provisions to address 21st century trade problems and create opportunities for the nearly half a billion people who call North America at home.
