Iran is estimated to hold approximately 440 kg [1] of uranium enriched to 60%, creating a significant deadlock in negotiations with the U.S.
The presence of this material is critical because 60% enrichment is close to weapons-grade levels. This proximity to nuclear weapon capability raises severe proliferation concerns and prevents a diplomatic breakthrough between the two nations.
According to the International Atomic Energy Agency (IAEA), the estimated 440 kg [1] of enriched uranium serves as the primary stumbling block in ongoing talks. The material can be further processed into a nuclear warhead, making its removal or neutralization a non-negotiable priority for U.S. officials.
President Donald Trump expressed a desire to cooperate with Iran to uncover and remove the material, he said [2]. However, the U.S. administration is also considering more aggressive measures to ensure the material is secured.
Trump said he is considering the option of deploying special forces on the ground to secure the high-enriched uranium [3]. This potential military escalation follows a period of heightened tension and military clashes between the U.S. and Iran in March 2026.
The U.S. goal remains the total elimination of the 60% enriched stockpile to prevent the possibility of a nuclear-armed Iran. Until a verifiable agreement on the removal of these materials is reached, the diplomatic path remains narrow, leaving the door open for unilateral U.S. action.
“Iran is estimated to hold approximately 440 kg of uranium enriched to 60%.”
The standoff centers on the technical threshold of nuclear enrichment; while 60% is not yet weapons-grade, the final leap to 90% is significantly shorter and faster than the initial enrichment process. By maintaining this stockpile, Iran retains a strategic hedge, while the U.S. views the material as an immediate security threat that may justify military intervention if diplomacy fails.
