In recent weeks, there has been a notable increase in pressure from various quarters in Washington to abolish U.S. trade duties on phosphate fertilizers imported from Morocco. Lawmakers, alongside significant agricultural organizations, are contending that the existing tariffs are exacerbating production costs for American farmers, who are already grappling with heightened input prices. This growing coalition has highlighted the importance of making essential agricultural resources more accessible to ensure the competitiveness of U.S. agriculture.
On Tuesday, U.S. Senator Roger Marshall took a decisive step by introducing the Lowering Input Costs for American Farmers Act. This proposed legislation aims to eliminate both the tariffs and countervailing duties that have been applied to phosphate fertilizer imports from Morocco, thereby formally terminating the U.S. duty order that was first established in April 2021. The bill has garnered support not only from Senator Marshall but also from lawmakers representing Iowa and Mississippi, indicating a bipartisan recognition of the issue at hand.
Furthermore, this legislative effort has received backing from prominent agricultural organizations, including the American Farm Bureau Federation, the American Soybean Association, and the National Corn Growers Association, as reported by industry publication World Fertilizer. This widespread support reflects a growing consensus among U.S. farmers that the tariffs, initially imposed following a complaint by The Mosaic Company—a U.S. fertilizer producer—are negatively impacting their operations by making a vital crop nutrient more expensive and limiting access to one of the world's largest phosphate suppliers, Morocco's OCP Group.
According to a report released in January 2026 by Texas A&M University’s Agricultural and Food Policy Center, the duties imposed on Moroccan phosphate resulted in a staggering 28.6% increase in U.S. diammonium phosphate prices during the initial tariff period. This has translated to an additional burden of approximately $6.9 billion in phosphorus fertilizer costs for American producers from 2021 to 2025. Agricultural organizations argue that the restrictions on Moroccan imports have significantly curtailed competition within an already concentrated fertilizer market predominantly controlled by Mosaic, further complicating the financial landscape for American farmers.
