The U.S. Department of the Interior's final decision to include both phosphate and potash on its critical minerals list marks a significant milestone for American agriculture and the fertilizer industry. This move elevates these essential nutrients to a national priority, recognizing their strategic role in crop production, food security, and supply-chain resilience.

Under the Energy Act of 2020, a critical mineral is defined as a non-fuel material that is (1) vital to national or economic security, (2) serves an indispensable function in manufacturing, and (3) has a supply chain vulnerable to disruption.

The inclusion of phosphate reverses a previous proposal that left it off the list-prompting strong advocacy from the USDA and farm groups who warned that excluding it posed serious risks to the U.S. food system. Phosphate prices have surged amid recent tariffs on major exporters like Saudi Arabia, Jordan, and Egypt, which supplied 86% of U.S. imports last year. These trade measures helped drive a 36% decline in phosphate imports from April to July compared to the same period a year earlier, according to The Fertilizer Institute (TFI).

The fertilizer industry hailed the decision. "Rightfully recognizing phosphate and potash as critical minerals will support American farmers across the country and help ensure high crop yields and stocked grocery store shelves," said TFI President and CEO Corey Rosenbusch. He emphasized the need to rethink how these essential inputs are treated in national policy.

Potash, which was on the original 2018 list but removed in 2022, returns due to its high-risk supply chain profile. The U.S. imports around 97% of its potash, almost entirely from Canada. With ongoing trade tensions and potential tariff threats, lawmakers and industry leaders have pushed for its reinstatement as a critical mineral.

Federal lawmakers such as Sen. Joni Ernst (R-IA) and Sen. Elissa Slotkin (D-MI) urged the Interior Department to add both minerals, warning that "modern agricultural systems would crumble" without them and that feeding a growing global population would be nearly impossible.

For U.S. ag professionals-farmers, cooperatives, agronomists, and input suppliers-this designation carries wide-reaching implications:

• Strategic recognition of fertilizer minerals as national assets.

• Potential for federal incentives to bolster domestic production and processing.

• Greater visibility into future supply-chain planning.

• Opportunities to stabilize input costs amid global volatility.

• Synergies with sustainable agriculture and precision ag technologies.

As the U.S. seeks to strengthen its domestic capabilities and reduce reliance on volatile international markets, this decision marks a turning point in the conversation about fertilizer security and the broader agricultural supply chain.
