What does Executive Order 14387 do?

EO 14387 delegated specified Defense Production Act authorities to the Agriculture Secretary for a continued supply of elemental phosphorus and glyphosate-based herbicides. The Secretary was to consult the Defense Secretary on nationwide priorities and allocations and issue orders or rules as needed. On April 13, 2026, USDA published changes to its delegations of authority that expressly assigned administration of EO 14387 functions to the Under Secretary for Marketing and Regulatory Programs and the Executive Director of its Office of Homeland Security. This administrative step does not establish that USDA issued a priority-rated contract, allocated a quantity of material or increased domestic production.

Later evidence reviewed September 27, 2026: USDA's April rule expressly assigned administration of EO 14387 within the department. No specific use of priority or allocation authority or resulting production increase was established.

Administration position: The order's assertions about supply risk, alternatives and national-defense necessity are presidential findings. The later USDA rule documents administrative follow-through, not independent verification of those assertions.

Before and after

Before the order

Defense Production Act authorities and USDA's Agriculture Priorities and Allocations System already existed; EO 13603 contained a separate allocation framework.

Existing pesticide, environmental, procurement and appropriations law continued to apply.

After the order

EO 14387 delegated a defined set of priority and allocation powers to the Agriculture Secretary for the two named inputs.

USDA's April 2026 rule assigned officials to administer the order and its allocations system. No reviewed primary record established a particular allocation order or measured supply increase.
