Mexico has emerged as the leading supplier of orange juice to the United States, challenging Brazil's dominance in the market. Since the implementation of the North American Free Trade Agreement (NAFTA) in 1993, which exempts Mexico from tariffs, American imports of Mexican FCOJ have surged from 9,772 tonnes to 74,680 in 2019, accounting for 46% of the US market. In contrast, Brazilian exports have seen a significant decrease, falling from 144,538 tons to 71,114 tons in the same year. The tariff exemption has been a key factor in Mexico's competitive advantage, as Brazilian juice faces a tariff of $415.86 per ton. Additionally, the article highlights the impact of tariffs and logistical costs on the value of Brazilian orange juice exports and the efforts to improve the global competitiveness of Brazilian orange juice through international agreements.
