Fertilizer tariffs bite farmers
A sector post said recent fertilizer tariffs are squeezing corn growers and tightening phosphate supplies that have been constrained since 2020. The agricultural outlet raised alarms about input cost pressure and potential crop impacts in the coming season (x.com). The thread flagged fertilizer availability as a trade‑policy knock‑on affecting planting decisions for 2027 and beyond (x.com).
Phosphate fertilizer duties that started in 2021 are back under federal review, and corn groups say the tariffs are still raising costs and limiting supply. (federalregister.gov) The United States International Trade Commission opened its five-year “sunset review” on March 2, 2026, to decide whether ending the duties on imports from Morocco and Russia would likely bring back injury to domestic producers. The orders were first issued on April 7, 2021. (federalregister.gov) Phosphate is one of the three main crop nutrients, alongside nitrogen and potash, and it is a core input for corn. USDA’s transportation dashboard says fertilizer accounts for 21 percent of total corn production costs. (agtransport.usda.gov) More than 50 state farm groups and eight national organizations, including the National Corn Growers Association and the American Soybean Association, asked the commission on April 2 to revoke the duties. Their letter said the United States “does not have sufficient domestic phosphate resources” to meet farm demand on its own. (ncga.com) Those groups say the trade case reshaped the market after at least one Moroccan supplier stopped shipping phosphate fertilizer to the United States. They told the commission that tighter supply and higher prices have hurt yields and farm finances. (ncga.com) The fight is not only about the 2021 phosphate case. North Dakota State University found that fertilizer tariffs imposed in April 2025 widened the price gap between United States and Canadian fertilizer markets, with the premium for diammonium phosphate in the Northern Plains reaching $343 per metric ton at its peak. (agweb.com) That same North Dakota State analysis estimated $110 million in tariff revenue from fertilizer imports between February and October 2025. The researchers said domestic importers and farmers bore most of that burden. (agweb.com) Domestic producers are arguing the opposite side. Mosaic and J.R. Simplot have told the government they want the countervailing duties kept in place, saying the protections are still needed, while other farm and fertilizer interests have pushed for removal. (hoosieragtoday.com) The legal process is still moving. The commission set April 1, 2026, as the deadline for initial responses and May 8, 2026, for comments on whether a full review is needed, with farm groups expecting a final decision in spring 2027.
