The trade flows in sugar and high-fructose corn sweetener (HFCS) among Mexico, Canada, and the United States consist mainly of U.S. exports of refined sugar to Mexico, US.-Canadian two-way trade in sugar and HFCS, and recent growth in U.S. HFCS exports to Mexico. The North American Free Trade Agreement (NAFTA) could increase these trade flows by reducing tariffs and allowing competitive advantage (for example, the United States in HFCS) to satisfy regional consumption habits.
