What restrictions does OFAC impose on individuals and legal entities?

OFAC sanctions can take various forms: from blocking the property of specific individuals and organizations to broad prohibitions on transactions with entire countries. Individuals on the SDN list have frozen assets, and Americans are prohibited from engaging in any dealings with them. Blocked assets include money, stocks, real estate, and any other property under U.S. control. OFAC can also impose sectoral sanctions, prohibiting certain types of activities in specific sectors of a country’s economy. All property of blocked persons under U.S. jurisdiction must be frozen, and any transactions with them require a special license from OFAC.
