The Future of Phosphate Fertilizer: Can Legislative Shifts Solve the Affordability Crisis?
For many growers, the bottom line is dictated by the cost of inputs. Among these, phosphate fertilizer remains a critical—and increasingly volatile—expense. A recent legislative push, specifically the Lowering Input Costs for American Farmers Act, signals a potential pivot in how the U.S. Manages its agricultural supply chain and trade relations with global leaders like Morocco.
The core of this movement is the proposed removal of countervailing duties on phosphate imports from Morocco. If these duties are eliminated, the impact could be immediate and substantial, potentially lowering the cost of phosphate fertilizer by over 20%, or roughly $150 per short ton (st).
Trade Barriers and the ‘Mosaic’ Effect
To understand where we are going, we have to glance at how we got here. In 2021, countervailing duties were imposed on phosphate imports from both Russia and Morocco. These measures followed allegations by US producer Mosaic that imports from these two nations were materially injuring the domestic market.
While intended to protect local industry, these duties have contributed to a trend where US phosphate prices have remained higher than historic norms. For the average farmer, this means higher overhead and tighter margins during a period of global economic instability.
The Import Gap: A Warning Sign
The data suggests a worrying contraction in import volumes. US combined imports of DAP (diammonium phosphate) and MAP (monoammonium phosphate) totaled 1.29 million tonnes in 2025. This is a sharp decline from the average of approximately 2.13 million tonnes seen between 2020 and 2024.
This decline highlights a growing reliance on a narrower set of supply sources, leaving the agricultural sector vulnerable to “black swan” events and geopolitical shocks.
Beyond Duties: A Multi-Pronged Legislative Strategy
The push to lower input costs isn’t limited to a single bill. Industry experts are tracking a broader legislative trend aimed at systemic reform. Alongside the effort to remove Moroccan duties, other key pieces of legislation have been filed, including:
- The Fertilizer Price Transparency Act: Aimed at bringing more clarity to how pricing is determined and communicated.
- The Fertilizer Research Act: Focused on long-term sustainability and efficiency in nutrient application.
These efforts suggest that the government is moving toward a strategy that combines immediate cost relief (via duty removal) with long-term structural improvements (via transparency and research).
The Sunset Review: A Critical Turning Point
The timing of these legislative moves is not accidental. They coincide with the US Department of Commerce’s five-year sunset review of the existing duties, conducted in partnership with the US International Trade Commission. This review represents a formal window for the government to decide if the 2021 protections are still necessary or if they have grow a hindrance to food security and farmer profitability.

Frequently Asked Questions
How much could phosphate fertilizer costs actually drop?
According to projections associated with the Lowering Input Costs for American Farmers Act, the elimination of duties could reduce costs by over 20%, or roughly $150 per short ton.
Why were duties placed on Morocco and Russia in the first place?
Duties were imposed in 2021 after the US producer Mosaic alleged that phosphate imports from these countries were causing material injury to the US market.
What is the difference between DAP and MAP?
Both are phosphate fertilizers; DAP (diammonium phosphate) and MAP (monoammonium phosphate) are the primary forms of phosphate imported into the US to support crop production.
