The purpose of this executive order is to ensure an adequate supply of elemental phosphorus and glyphosate-based herbicides. Elemental phosphorus is pervasive in defense supply chains and critical to military readiness and national defense and is also increasingly important in modern lithium battery chemistries, which are used in weapons-system supply chains. Elemental phosphorus is also a critical precursor element for the production of glyphosate-based herbicide, which plays a critical role in maintaining America’s agricultural advantage by enabling farmers to efficiently and cost-effectively produce food and livestock feed. Therefore, pursuant to the Defense Production Act of 1950, the secretary of agriculture is directed to ensure a continued and adequate supply of elemental phosphorus and glyphosate-based herbicides. The secretary, in consultation with the secretary of war, is to determine the proper nationwide priorities and allocation of all materials, services and facilities necessary to ensure a continued adequate supply of these materials.
