Primary vs Secondary Sanctions: Who Is Restricted

Primary sanctions impose direct prohibitions on people and conduct within the issuing state’s jurisdiction, while secondary sanctions threaten specified consequences for certain foreign dealings even without the same jurisdictional link

“Primary” and “secondary” sanctions describe two different ways an issuing government can restrict economic activity. Primary sanctions generally prohibit covered persons from engaging in specified conduct because the transaction or actor falls within the issuer’s jurisdiction. Former U.S. Treasury Secretary Jacob Lew described U.S. primary sanctions as focusing on activities of U.S. individuals and companies. Secondary sanctions generally target foreign persons for specified dealings with a sanctioned country, sector or party even when the underlying activity does not otherwise touch the United States. These are useful categories, but the legal text of each program controls. ^[1]^[2]

For U.S. primary sanctions, the jurisdictional hooks can include a U.S. person, property in the United States, a U.S.-organized entity, conduct in U.S. territory or a payment routed through the U.S. financial system. Their exact reach varies by statute, executive order and regulation; some programs also address foreign branches or owned or controlled entities. OFAC says its programs range from broad geographic restrictions to targeted blocking and sectoral measures. A transaction can therefore be prohibited for one participant, permitted for another and still impossible in practice because a U.S. bank or service provider cannot take part. ^[3]^[4]

Secondary sanctions work through threatened consequences rather than a universal command to every foreign actor. Treasury has explained that they may threaten to cut a foreign person off from the U.S. financial system for specified conduct with a sanctioned entity even when the conduct has no direct U.S. nexus. Depending on the authority, the consequence may be blocking designation, restrictions on correspondent or payable-through accounts, denial of export privileges, procurement limits or another menu-based measure. A foreign company may decide the U.S. access at risk is more valuable than the proposed transaction, which gives the measure influence beyond U.S. borders. ^[1]^[2]^[5]

Exposure to secondary sanctions is not always the same as violating a primary prohibition. Some authorities let the government designate a foreign person after finding that it knowingly conducted or facilitated defined activity. OFAC’s Russia-related guidance, for example, says certain foreign financial institutions may be blocked or lose access to U.S. correspondent and payable-through accounts. Its Iran financial-sanctions guidance likewise describes a Treasury finding before account restrictions are imposed. The relevant provision determines whether a consequence is mandatory or discretionary, what knowledge standard applies and whether notice or a formal designation is required. ^[5]^[6]

The label “sanctioned” is therefore incomplete. A blocked person’s property may be frozen when it comes within U.S. possession or control, while a bank on OFAC’s CAPTA List may face account restrictions without every item of its property being blocked. Sectoral rules can prohibit only particular financing, debt, equity, services or transactions. Ownership rules can extend restrictions to entities owned by listed persons even if the subsidiary is not named. Compliance starts with the governing authority, applicable lists, definitions and ownership or control tests, not with a headline or a simple name match. ^[3]^[5]^[6]

Exceptions and authorizations also matter. OFAC defines a general license as a public, self-executing authorization for categories of transactions that would otherwise be prohibited, while a specific license authorizes identified activity for a particular applicant. Exemptions may be written directly into law. OFAC notes that, subject to program-specific rules, non-U.S. persons generally do not risk sanctions for facilitating conduct that a U.S. person could undertake without a specific license. Humanitarian, agricultural, medical, communications and official-business provisions can differ substantially across programs and change over time. ^[7]^[8]

Secondary sanctions can create conflicts between legal systems. The European Commission says the EU does not recognize certain extraterritorial applications of third-country laws and uses its blocking statute to protect EU operators from measures listed in the statute’s annex. The rules can nullify specified foreign judgments, permit recovery of some damages and prohibit compliance with covered foreign requirements unless authorization is granted. That means a company may face pressure from one jurisdiction and countervailing duties in another. Commercial withdrawal can also be voluntary risk management rather than proof that local law required it. ^[2]^[9]

To analyze a sanctions claim, identify the issuing authority, program, actor, currency and payment path; then ask whether the conduct is directly prohibited, merely exposes a party to designation, or is allowed by an exemption or license. Check the current official list and program page, the operative regulation or order, any general license and the effective date. OFAC cautions that its FAQs are general information and that statutes, executive orders, regulations and Federal Register documents contain the legal requirements. Because facts and rules change, businesses should use qualified sanctions counsel for a real transaction rather than treat this distinction as a compliance determination. ^[3]^[4]^[7]^[10]
