"Blocking" refers to freezing assets or other property. Blocking immediately imposes an across-the-board prohibition against transfers or dealings of any kind with regard to the property.
OFAC authorities may require U.S. persons to block all property and interests in property of certain persons, known as "blocked persons." When this is the case, any property and interests in property of a blocked person that are within the United States or within the possession or control of a U.S. person must be blocked (i.e., "frozen")—not seized—and may not be transferred, withdrawn, or otherwise dealt in. Title to the blocked property remains with the blocked person, but the exercise of powers and privileges normally associated with ownership is prohibited without authorization from OFAC.
In addition, parties must report blocked property to OFAC within 10 business days of the property becoming blocked. Blocked persons include persons that appear on OFAC’s List of Specially Designated Nationals and Blocked Persons (SDN List), foreign governments subject to blocking, and persons blocked pursuant to OFAC’s “50 Percent Rule.” For further information, see FAQ 401 and OFAC guidance on the "50 Percent Rule."
The term "property," as defined in various OFAC regulations, includes financial property (e.g., money, checks, savings accounts, stocks, bonds, debt, or any other financial instruments), real, tangible, and intangible assets (e.g., goods, merchandise, ships, land contracts, and real estate), and any other property or interests therein present, future, or contingent. For information on how OFAC defines property in a particular sanctions program, please see the relevant OFAC implementing regulations and the Sanctions Programs and Country Information page on OFAC’s website.
