International trade sanctions and the OFAC SDN List
Economic and trade sanctions are restrictive measures imposed by governments and international bodies to influence the conduct of states, entities, or individuals. They are a central tool of foreign policy and national security, and they create significant legal obligations for businesses and individuals worldwide. This article outlines how sanctions are structured and explains the United States' Specially Designated Nationals (SDN) List.
Types of sanctions
Sanctions take several forms:
- Comprehensive sanctions restrict nearly all dealings with a country or region.
- Sectoral sanctions target specific parts of an economy, such as finance or energy.
- List-based (targeted) sanctions apply to named persons and entities, freezing their assets and prohibiting dealings with them.
- Secondary sanctions extend consequences to non-US or non-domestic parties that deal with sanctioned targets.
Because different jurisdictions maintain their own programmes, a single transaction can be subject to overlapping regimes.
OFAC and the SDN List
In the United States, most sanctions are administered by the Office of Foreign Assets Control (OFAC), part of the Department of the Treasury. OFAC maintains the SDN List, a register of individuals and entities whose assets are blocked and with whom US persons are generally prohibited from dealing. Being added to the list — "designation" — can effectively cut a person or company off from the US financial system and from many international counterparties.
The 50 percent rule
A key feature of the US regime is the "50 percent rule": an entity that is owned, 50 percent or more, in the aggregate, by one or more blocked persons is itself treated as blocked, even if it is not named on the list. This makes ownership screening essential for compliance.
Licences and exemptions
Sanctions regimes provide for authorisations. A general licence permits a defined category of otherwise-prohibited activity, while a specific licence authorises a particular transaction on application. Humanitarian and other exemptions may also apply. Careful analysis is needed to determine whether an activity is permitted.
Delisting
A person or entity on the SDN List may seek delisting by petitioning OFAC, typically by demonstrating a change in circumstances or that the designation was based on a mistake. The process is evidence-based and can take time. Other regimes, such as those of the European Union and the United Kingdom, provide their own review and challenge mechanisms.
Other regimes
The European Union and the United Kingdom operate their own sanctions frameworks, with consolidated lists and asset-freeze measures. Multinational businesses must often comply with several regimes at once, and the details — including who is targeted and what is prohibited — can differ between them.
Compliance
Because the consequences of a breach can be severe, organisations maintain sanctions-compliance programmes built around screening counterparties against the relevant lists, applying the ownership rules, and seeking licences where needed. Sanctions law is dynamic, and lists and programmes change frequently.
A tool of foreign policy
Sanctions are used to pursue a range of objectives: to respond to armed conflict, to counter terrorism and proliferation, to address human-rights abuses, and to press governments to change their conduct. They can be imposed by individual states, by regional bodies such as the European Union, and by the United Nations Security Council, whose measures member states implement in their own law. Because several layers can apply at once, sanctions compliance is a global concern rather than a purely national one.
Consequences of a breach
Breaching sanctions can carry serious consequences, including substantial civil penalties and, in some cases, criminal liability. Enforcement authorities may act against both the direct violator and parties that facilitate a prohibited transaction. Because US measures can reach conduct connected to the US financial system, and because secondary sanctions can affect non-US parties, businesses far from the imposing country can be exposed.
Screening and the ownership rules
Practical compliance centres on screening counterparties, customers, and transactions against the relevant lists, and on applying ownership rules such as the OFAC 50 percent rule. Effective screening must account for name variations, aliases, and frequent changes to the lists. Where a proposed activity may be prohibited, parties assess whether a general or specific licence is available before proceeding.
Practical takeaways
For businesses and individuals, the practical significance of sanctions lies in the breadth of their reach and the speed at which they change. A single transaction may touch several regimes at once — for example those of the United States, the European Union, and the United Kingdom — each with its own lists and prohibitions. Effective management therefore combines up-to-date screening, application of ownership rules such as the OFAC 50 percent rule, and, where needed, applications for licences before proceeding. Where a person or entity considers a designation to be mistaken or out of date, the available review and delisting mechanisms provide a route to challenge it, though the process is evidence-based and can take time. Because the landscape shifts frequently, sanctions compliance is best treated as an ongoing process rather than a one-off check.
