February 19th — According to White House officials, U.S. President Donald Trump signed an executive order aimed at protecting the domestic supply of elemental phosphorus, which is required by the U.S. military, and glyphosate-based herbicides commonly used in American agricultural production. On February 18th, Trump invoked the Defense Production Act through this executive order to secure the domestic supply chains for these two categories of materials. Chempricehub Analysis: Glyphosate, Bull-Bear Score: 1 U.S. President Donald Trump signed an executive order invoking the Defense Production Act to protect the domestic supply of glyphosate-based herbicides, aiming to reduce import dependence and strengthen domestic production. This is expected to tighten global glyphosate supply, particularly impacting U.S. agricultural demand, and may drive up spot prices in the short term. The positive factors primarily stem from expectations of supply tightening, but the extent of the impact is limited by the global market balance, hence it is rated as a moderate positive. Elemental Phosphorus, Bull-Bear Score: 1 The executive order emphasizes protecting the domestic supply chain of elemental phosphorus to meet military and agricultural needs, and invoking the Defense Production Act will stimulate domestic production and stockpiling. This may lead to reduced supply of elemental phosphorus in the international market, driving up spot prices, particularly in the fertilizer and chemical raw materials sectors. The positive drivers mainly come from demand support due to supply chain security policies, but since the event does not directly expand the scale of demand, it is rated as a moderate positive.
