SDN stands for Specially Designated Nationals. These are individuals, entities, and organizations identified by OFAC as subject to sanctions. Any property or interests in property of an SDN within U.S. jurisdiction are blocked. U.S. persons are generally prohibited from conducting transactions with SDNs. The SDN list is regularly updated and publicly available on OFAC’s website. Compliance requires screening clients and counterparties to ensure no dealings with SDNs occur.
