US President Donald Trump will temporarily suspend tariffs on phosphate fertilizers from Morocco as his administration seeks to bolster a struggling agricultural economy and allay consumer fears about food inflation.

Fertilizer prices surged earlier this year after US attacks on Iran disrupted shipments of fertilizer and related production inputs through the Strait of Hormuz, prompting countries to protect supplies for their farmers.

The American Farm Bureau Federation (AFF) had appealed directly to the White House in March to protect supplies, including through a temporary suspension of tariffs.

In a proclamation issued Monday, the president declared a "national emergency regarding threats to the availability of sufficient fertilizer supplies to meet America's agricultural demand." The suspension will last eight months, "or until the emergency is terminated," according to a White House fact sheet.

The proclamation states that supply chains for phosphate fertilizers and other fertilizer inputs "have been disrupted in recent months due to, among other things, conflicts in fertilizer-producing regions, as well as trade actions by major fertilizer-producing countries."

Fertilizer tariffs under pressure from the supply crisis: Fertilizer prices have been a major concern for American farmers, a key voting bloc for Trump, even as his tariffs last year drove up crop nutrient prices and put pressure on grain markets.

Nearly 70% of American farmers said they could not afford all the fertilizer they needed, according to a report by the AFF.

Spot prices for diammonium phosphate fertilizer in the U.S. Gulf Coast region earlier this month reached their highest level since 2025 before falling to their lowest point in over a month, according to Bloomberg Green Markets.
