Trump lifts duties on Moroccan phosphate fertilizer to aid farmers

President Trump declared a national emergency on June 29, invoking threats to the US food supply as justification for temporarily suspending duties on Moroccan phosphate fertilizer. The move, which lifts tariffs that have been in place since 2021, is designed to bring down input costs for American farmers and ease food inflation that has stubbornly persisted through supply chain disruptions.

The suspension covers countervailing and anti-dumping duties on phosphate fertilizer imports from Morocco for up to eight months. Those duties have typically ranged from 16-17%, a meaningful surcharge on a commodity that sits at the foundation of American agriculture.

Why phosphate matters more than you think

Morocco holds approximately 70% of global phosphate rock reserves. One country controls the overwhelming majority of a resource that every farmer on Earth depends on. The country’s state-owned company OCP is the dominant player in this trade.

The duties Trump just suspended were originally imposed in March 2021, following a petition by US producer The Mosaic Company. The argument at the time was straightforward: Moroccan phosphate was being sold at unfairly low prices, undercutting domestic producers. The US International Trade Commission and the Commerce Department agreed, and the tariffs went into effect.

The political path to this moment

The administration’s discussions about lifting the duties began back in March 2026, driven by advocacy from farm groups and lawmakers. Corn growers were particularly vocal, which makes sense given that corn is one of the most fertilizer-intensive crops grown in the US.

In April 2026, several senators introduced legislation to eliminate the duties permanently. Senator Roger Marshall of Kansas was among the sponsors.

A five-year sunset review of the duties was already underway as of early 2026, conducted by the US International Trade Commission and the Commerce Department. Trump’s emergency declaration under trade law offered a faster route, bypassing the typical review timeline entirely.

What this means for markets and investors

The Mosaic Company, the US producer that originally petitioned for the duties, finds itself on the losing end of this decision. Mosaic benefited from reduced Moroccan competition over the past five years. With those protections now suspended, the company faces renewed price pressure from OCP, which can produce phosphate at significantly lower costs given Morocco’s enormous reserve base.

The eight-month suspension creates a defined window. If the sunset review concludes that duties should be lifted permanently, or if Congress passes legislation to that effect, the suspension becomes a moot point. If neither happens, the market faces a potential return to tariffed pricing.

Investors watching the agricultural supply chain should pay attention to the sunset review timeline and the congressional legislation introduced in April. The eight-month suspension is temporary, and the permanent resolution, whether through regulatory review or legislation, will determine the long-term competitive landscape for phosphate fertilizer in the US market.
