The “Environment” chapter contains the most comprehensive environmental commitments applicable to a previous U.S. agreement, including obligations to combat trade in wild plants, wood and fish; Strengthen law enforcement networks to curb human trafficking; and address pressing environmental issues, such as air quality and marine waste. The U.S.-Mexico-Mexico Agreement (USMCA) is a trade agreement between these parties. The USMCA replaced the North American Free Trade Agreement (NAFTA). The rules of origin of the automobile (ROO) require that a certain portion of the value of an automobile originate from 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 accordance with section 103 (b) (2) of the USMCA Act, the date of the interim provisions to be recommended will be at the latest after the USMCA comes into force and the implementation of the uniform rules of origin.  Uniform regulations at the USMCA help interpret the various chapters of the USMCA, first chapters 4-7. These rules were published one month before the trade agreement came into force and replaced NAFTA on July 1, 2020.  The idea of replacing NAFTA came out of the line before President Trump`s election, as a candidate, President Trump was in favor of renegotiating NAFTA in an attempt to secure more favourable terms for the United States. The USMCA officially began to take shape when the Trump administration sent a 90-day message to Congress that it would begin discussions for a renegotiation of NAFTA. Discussions officially began on August 16, 2017 and ended on September 30, 2018. One of President Trump`s main goals in the renegotiation is to ensure that the deal benefits American workers. The United States, Mexico and Canada have approved a laboratory chapter that brings work obligations to the heart of the agreement, makes them fully applicable and is the strongest provisions of any trade agreement. The United States, Mexico and Canada have reached an agreement to modernize NAFTA, which is 25 years old, into a high-level agreement of the 21st century. The new agreement between the United States and Mexico-Canada (USMCA) will support mutually beneficial trade, which will lead to freer markets, fairer trade and robust economic growth in North America.
