Once it has been determined that you or your institution is holding or is in possession of artwork that is the property of an SDGT or a person otherwise blocked pursuant to E.O. 13224, or in which such a person has an interest, you or your institution must ensure that access to that artwork is denied to the SDGT or blocked person and that your institution complies with OFAC regulations related to blocked assets, including restrictions on the sale or transfer of the artwork to third parties. Pursuant to 31 CFR section 501.603, blocked property, physical or financial, must be reported to OFAC within 10 business days; U.S. persons must also comply with all other applicable reporting obligations. See FAQs 49 and 50. Questions about whether a transaction should be blocked should be directed to OFAC at 202-622-2490 or firstname.lastname@example.org.
