The "Enhanced Iran Sanctions Act of 2025" establishes a robust framework for imposing sanctions on foreign persons who knowingly engage in logistical transactions, processing, export, or sale of oil, gas, liquefied natural gas, and related petrochemical products from the Islamic Republic of Iran. The policy aims to prevent Iran from acquiring nuclear weapons, counter its aggression and terrorism, and deny it financial resources for destabilizing activities and repression of its citizens.

Under this Act, the President must impose sanctions on such foreign persons, including banks, financial institutions, insurance providers, and flagging registries. Sanctions also extend to subsidiaries, corporate officers, and immediate family members of sanctioned individuals. The penalties include the blocking of property and interests in property within U.S. jurisdiction and rendering sanctioned aliens inadmissible to the United States, with their visas revoked.

The bill provides specific exceptions for the importation of goods, compliance with international obligations, authorized law enforcement activities, and the provision of humanitarian assistance such as agricultural commodities, food, medicine, and medical devices. An exception also exists for provisions necessary for the safety of vessels and crew. The President retains the authority to issue case-by-case waivers for up to 180 days if deemed vital to U.S. national interests, with congressional notification.

Furthermore, the Act mandates the establishment of an Interagency Working Group on Iranian Sanctions, led by the Secretary of State, within 180 days of enactment. This group will endeavor to create a multilateral contact group with allied nations to coordinate international efforts, share information on sanctions frameworks and evasion tactics, and align measures to curb Iran's malign activities, including uranium enrichment and ballistic missile production.

Finally, the legislation amends existing law to require private sector reporting on persons engaged in sanctionable activities or attempting to evade sanctions under this Act, particularly those using proceeds from the sale of intercepted Iranian energy products.
