Mosaic and Simplot Support Keeping Phosphate Fertilizer Tariffs

Key Takeaways

• Mosaic, Simplot back maintaining phosphate fertilizer tariffs.
• Nutrien urges lifting duties citing global supply shifts.
• Ag groups lobby Commerce to revoke tariffs, citing domestic shortages.
• Texas A&M study estimates $6.9B farmer cost from duties.
• Tariffs range 16.6%–47%, under five‑year sunset review.

Pulse Analysis

The current countervailing duties on phosphate fertilizer were imposed after Mosaic filed a trade case in 2021, targeting imports from Morocco and Russia. With rates between 16.6% and 47%, the measures were intended to level the playing field for U.S. producers and safeguard domestic processing jobs. As the five‑year sunset review commences, the Commerce Department and the International Trade Commission must decide whether the original injury findings still hold, a decision that will reverberate through the entire agricultural supply chain.

Industry sentiment is sharply divided. Mosaic and Simplot argue that the duties remain essential to protect U.S. capacity and prevent market distortion, while Nutrien—responsible for about 20% of domestic phosphate output—now calls for removal, pointing to evolving global supply dynamics. Meanwhile, a coalition of commodity groups, including the National Corn Growers Association and the American Soybean Association, is pressing for revocation, warning that the U.S. lacks sufficient native phosphate resources to meet demand without affordable imports. A Texas A&M study quantifies the stakes, attributing $6.9 billion in added costs to U.S. farmers, with corn alone absorbing $3 billion.

The policy decision will shape input costs for a sector already grappling with narrow profit margins. If the duties are retained, fertilizer prices are likely to stay elevated, pressuring planting decisions and potentially reducing yields. Conversely, lifting the tariffs could lower costs, improve farm cash flow, and enhance U.S. agricultural competitiveness in global markets. Stakeholders will be watching the review’s outcome closely, as it will set a precedent for how trade remedies intersect with food security and farm economics in the years ahead.
