186. How do I know that a person has been designated under the GHRAVITY E.O.?

Persons designated under the GHRAVITY E.O. appear on the publicly available Specially Designated Nationals List (SDN list) bearing the [HRIT] tag. U.S. persons are obligated to block property involving the persons bearing the tag [HRIT] on the SDN list, unless the transaction is exempt or otherwise authorized by OFAC.
