OFAC SDN Sanctions List
Screening in Dubai

The OFAC Specially Designated Nationals and Blocked Persons List (SDN List) is the primary US government sanctions list, maintained by the US Treasury Department's Office of Foreign Assets Control. It contains the names of individuals, companies, vessels, and aircraft whose assets are blocked under US law and with whom US persons and, in many cases, non-US persons are prohibited from transacting. The SDN List is updated frequently — sometimes daily — and contains over 12,000 entries. UAE businesses must screen customers, counterparties, beneficial owners, and transactions against the SDN List as a fundamental sanctions compliance obligation.

OFAC's 50% Rule provides that any entity that is 50% or more owned — directly or indirectly — by an SDN-designated person is itself treated as blocked, even if not named on the SDN List. For UAE businesses, this is particularly significant because many UAE corporate structures involve beneficial owners from sanctioned jurisdictions, and the 50% Rule can make a UAE-registered company an effective SDN through its ownership chain. Robust beneficial ownership (UBO) screening — going beyond the entity name to the full ownership structure — is essential for UAE sanctions compliance programs. Dr. Shaun Gregory Morgan advises UAE businesses on implementing 50% Rule-compliant UBO screening frameworks.

OFAC updates the SDN List on an ongoing basis — additions and removals can occur multiple times per week. UAE businesses cannot rely solely on one-time customer screening; they must implement ongoing monitoring programs that re-screen existing customers, counterparties, and beneficial owners against updated sanctions lists on a regular basis. Automated sanctions screening technology, combined with legal review protocols for name-match alerts, is the current standard for UAE financial institutions and large trading companies. Dr. Shaun Gregory Morgan advises on implementing screening programs that meet OFAC's expectations for UAE market conditions.

The SDN List imposes comprehensive blocking — all assets of listed persons are frozen and all transactions are prohibited. The Sectoral Sanctions Identifications (SSI) List, by contrast, imposes targeted, sector-specific restrictions on listed entities rather than full blocking. SSI designees — primarily Russian energy, defense, and financial companies designated under Executive Orders 13662 and 14024 — are not fully blocked, but US persons are prohibited from certain defined dealings, including new debt of specified maturities and new equity. UAE businesses with Russian counterparty relationships must understand which list applies and what specific dealings are restricted under each program.

If a UAE company discovers it has transacted with an OFAC SDN-designated party, it should immediately: (1) cease all further transactions with the SDN; (2) engage an experienced OFAC sanctions list expert in Dubai to assess the nature and extent of the violation; (3) preserve all relevant transaction records under legal privilege; (4) evaluate whether voluntary self-disclosure (VSD) to OFAC is strategically appropriate — a well-crafted VSD can reduce civil penalties by 50%; and (5) implement enhanced screening protocols to prevent recurrence. Early legal intervention is the most important factor in achieving a favorable enforcement outcome.
