One Down, Two to Go: Mexico Is First Country to Ratify NAFTA Replacement

On June 19, 2019, Mexico became the first country to ratify the United States-Mexico-Canada Agreement (USMCA). By a vote of 114 to 4, Mexico’s Senate approved the replacement to the North America Free Trade Agreement, making Mexico the first country to ratify to the new treaty.

In many ways a carbon copy of the old NAFTA,[1] the USMCA significantly impacts the $1.2 trillion in annual trade between the three countries, particularly in the automotive, agricultural, and services industries. The biggest changes include:

  • Country of Origin Rules: The USMCA contains a 75% originating-content requirement for most passenger vehicles and light trucks, and automotive parts (steel and aluminum) with at least a 70% requirement. Additionally, 40% to 45% of any vehicle production must be made by workers earning at least $16 per hour.  
  • Intellectual Property and Digital Trade: The USMCA contains a new 10-year protection period for biological-drug patents, and extends copyright protections to last for the author's lifetime plus an additional 70 years.
  • Agriculture: Both Canada and the United States will gain greater access to each other’s agricultural markets. The United States will be able to export more dairy, poultry, and eggs into Canada. In turn, Canada will be permitted to export additional sugar and sugar-containing products into the United States.
  • Dispute System: NAFTA's bi-national panel review for investor-state dispute resolution mechanism between the United States and Canada has been eliminated.
  • Currency: The USMCA includes a new chapter that addresses macroeconomic and exchange-rate matters with aims to reduce unfair currency practices.
  • Sunset Clause: The USMCA contains a 16-year sunset clause, with mandatory reviews every six years.

What's Next?

The USMCA has been in the works since mid-2017. Negotiations commenced on August 16, 2017, and an agreement was signed on November 30, 2018 by the leaders of each respective country.[2]

As noted above, Mexico’s Senate ratified the USMCA by an overwhelming majority. Both Canada and the United States have officially started the process for their respective ratification of the USMCA. Many obstacles to the passage of the USMCA in the United States are being removed. For example, the recent labor reform passed in April 2019 by Mexico’s Congress eliminated a major barrier for the agreement.[3]

Another critical step forward came on May 17, 2019, when the United States dropped tariffs on steel and aluminum imports from Canada and Mexico.[4] The lifting of those tariffs – and retaliatory duties imposed by Canada and Mexico – marks another milestone in the journey to the USMCA’s approval, which is expected to be fully ratified by the fall of 2019.
