The United States Geological Survey has added both phosphate and potash to the federal list of minerals considered critical to national security and economic stability. The decision, published Thursday by the U.S. Department of the Interior, raises the total number of designated critical minerals to 60.
Phosphate had been omitted from earlier drafts despite pleas from farm and fertilizer industry groups that it is vital for crop production and vulnerable to international supply disruptions.
Potash, which the U.S. relies on Canada for about 97 % of its supply, had been on the 2018 list but removed in subsequent updates.
Supporters say the change addresses feedstock shortages, volatile fertilizer markets and supply-chain risks for U.S. agriculture.
Under the designation, projects to mine, process or recycle these minerals may be eligible for federal tax credits, streamlined permitting and priority-consideration for grants or loans.
