The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC), with the U.S. Department of State and the U.S. Coast Guard, is issuing this advisory to alert persons globally to the significant U.S. sanctions risks for parties involved in petroleum shipments to the Government of Syria. These shipments create significant sanctions risk for entities and individuals in the shipping industry, including shipping companies, vessel owners, managers, operators, insurers, and financial institutions. Countries such as Iran and Russia have been involved in providing the Government of Syriawith petroleum. Those who in any way facilitate the financial transfers, logistics, or insurance associated with these or other petroleum shipments are at risk of being targeted by the United States for sanctions. The United States is committed to disrupting illicit financial and other support to the Government of Syria, to include transporting petroleum to its state-owned and -operated ports, regardless of the location or nationality of those facilitating such support.

The United States and its international partners continue to demonstrate resolve to disrupt support for the Assad regime by preventing the normalization of economic and diplomatic relations and the provision of reconstruction funding, as well as permanently denying the regime the use of chemical weapons. The United States is committed to isolating the Assad regime and its supporters from the global financial and trade system in response to the continued atrocities committed by the regime against the Syrian people. The United States and European Union (EU) maintain sanctions programs against Syria, and the United States will continue tomaximize pressure on the Assad regime and impose additional financial costs on the regime and its network of financial and logistics facilitators.

In connection with this activity, in November 2018, OFAC sanctioned Iranian and Russian private and public sector entities involved in procuring Iranian oil for Syria. This scheme used a payment offsetting arrangement in which the sale and shipment of Iranian oil to Syria provided hundreds of millions of dollars to Iran’s terror proxy groups, including Hizballah, HAMAS, and the Islamic Revolutionary Guard Corps Qods Force (IRGC-QF).

United States sanctions regulations broadly prohibit trade and other transactions, subject to U.S. jurisdiction, with the Government of Syria, and has the authority to sanction entities or individuals who provide support to the Government of Syria—including those who deliver or finance petroleum shipments to the Government of Syria or government-owned entities,
such as the U.S.-designated Syrian Company for Oil Transport or Banias Refinery Company.

This advisory contains an annex providing a non-exhaustive list of vessels that have delivered petroleum to Syria, engaged in Ship-to-Ship (STS) transfers of petroleum destined for Syria, or have exported Syrian petroleum since 2016 [1]. Some of these shipments and transfers have involved Iranian-origin oil.

Sanctions Risks and OFAC Authorities

Insurers, shipping companies, financial institutions, and others involved in petroleum-related shipping transactions with the Government of Syria may be subject to designation under one or more sanctions authorities. Similarly, individuals and entities knowingly engaged in certain transactions relating to the purchase, acquisition, sale, transport, or marketing of petroleum or petroleum products from Iran or providing material support to certain Iran-related persons on OFAC’s list of Specially Designated Nationals and Blocked Persons (SDN List) risk being sanctioned under U.S. sanctions authorities relating to Iran, unless an exception applies.

A high-level overview of these sanctions authorities follows. However, this overview is not intended to be a comprehensive summary of all U.S. sanctions authorities related to Syria and Iran. More information on the Syria and Iran sanctions programs can be found on Treasury’s website. Please note this section is current as of the date of this advisory. The most up-to-date information can be found on Treasury’s website and the hyperlinks listed in the footnotes below.


The U.S. government will aggressively target for designation any person who provides support to the regime, for example by facilitating exports to or imports from the Government of Syria, including government-owned entities, unless such exportation or importation is otherwise exempt or authorized. [2]

The United States also prohibits, among other things, transactions subject to U.S. jurisdiction that, directly or indirectly, involve the Government of Syria, or entities sanctioned under the Syria Sanctions Regulations (see, e.g., Executive Order 13582, “Blocking Property of the Government of Syria and Prohibiting Certain Transactions With Respect toSyria” and the Syrian Sanctions Regulations, 31 C.F.R. Part 542 (SSR) ).


The United States is committed to enforcing sanctions against those who engage in prohibited transactions under the Iranian Transactions and Sanctions Regulations, 31 C.F.R. part 560 (ITSR) , and will continue to aggressively target those involved in sanctionable activities under other Iran-related sanctions authorities in support of the Iranian regime’s malign activities. Pursuant to U.S. sanctions authorities, non-U.S. persons—including foreign financial institutions—may be subject to sanctions for knowingly conducting significant transactions for, or knowingly providing significant support to, certain Iran-related persons on OFAC’s SDN List, including the National Iranian Oil Company, the National Iranian Tanker Company, and the Islamic Republic of Iran Shipping Lines, unless an exception applies. Further, non-U.S. persons that knowingly own, operate, control, or insure a vessel that transports crude oil from Iran to Syria or other countries that have not received a significant reduction exception pursuant to section 1245 of the National Defense Authorization Act for Fiscal Year 2012 could be subject to secondary sanctions under the Iran Sanctions Act. Even when a significant reduction exception applies, the involvement of the IRGC or any other person designated in connection with Iran’s support for international terrorism or its proliferation of weapons of mass destruction or their means of delivery is outside the scope of the significant reduction exception and the conduct could be subject to U.S. sanctions.

OFAC administers and enforces a comprehensive trade embargo against Iran as set forth in the ITSR and Executive Orders issued under the authority of the International Emergency Economic Powers Act, 50 U.S.C. §§ 1701-06, and other statutes. The ITSR prohibits most direct and indirect transactions with Iran by U.S. persons or within the United States, unless authorized by OFAC or exempted by statute. [3] Further, absent an applicable exemption or OFAC authorization, foreign persons, including foreign financial institutions, are prohibited from processing transactions to or through the United States in violation of these prohibitions, including transactions through U.S. correspondent accounts for or on behalf of Iranian financial institutions, other persons located in Iran, or where the benefit of those services is otherwise received in Iran.

Deceptive Shipping Practices

As the global community increases its pressure on the Government of Syria, persons in the petroleum shipping industry continue to deploy deceptive practices by obfuscating the destination and recipient of oil shipments in the Mediterranean Sea ultimately destined for Syria.

The following list provides examples of the types of tactics used to obfuscate the destination of petroleum bound for Syria.

Falsifying Cargo and Vessel Documents: Complete and accurate shipping documentation is critical to ensuring all parties to a transaction understand the parties, goods, and vessels involved in a given shipment. Bills of lading, certificates of origin, invoices, packing lists, proof of insurance, and lists of last ports of call are examples of documentation that typically accompanies a shipping transaction. Shipping companies have been known to falsify vessel and cargo documents to obscure the destination of petroleum shipments.

Ship to Ship (STS) Transfers: STS transfers are a method of transferring cargo from one ship to another while at sea rather than while located in port. STS transfers can conceal the origin or destination of cargo.

Disabling Automatic Identification System (AIS): AIS is a collision avoidance system, which transmits, at a minimum, a vessel’s identification and select navigational and positional data via very high frequency (VHF) radio waves. While AIS was not specifically designed for vessel tracking, it is often used for this purpose via terrestrial and satellite receivers feeding this information to commercial ship tracking services. Ships meeting certain tonnage thresholds and engaged in international voyages are required to carry and operate AIS; however, vessels carrying petroleum to Syria have been known to intentionally disable their AIS transponders to mask their movements. This tactic can conceal the destination of cargo destined for the Government of Syria.

Vessel Name Changes: The owners of vessels that have engaged in illicit activities are known to change the name of a vessel in an attempt to obfuscate its prior illicit activities. For this reason, it is essential to research a vessel not only by name, but also by its International Maritime Organization (IMO) number.

Risk Mitigation Measures

The risk of engaging in prohibited activity or processing prohibited transactions can be potentially mitigated by implementing the following types of measures:

Strengthen Anti-Money Laundering/Countering the Financing of Terrorism (AML/CFT) Compliance: Financial institutions and companies are strongly encouraged to employ risk mitigation measures consistent with Financial Action Task Force standards designed to combat money laundering, and terrorist and proliferation financing. This includes the adoption of appropriate due diligence policies and procedures by financial institutions and non-financial gatekeepers and promoting beneficial ownership transparency for legal entities, particularly as related to the scenarios outlined above.

Monitor for AIS Manipulation: Ship registries, insurers, charterers, vessel owners, or port operators should consider investigating vessels that appear to have turned off their AIS while operating in the Mediterranean and Red Seas. Any other signs of manipulating AIS transponders should be considered red flags for potential illicit activity and should be investigated fully prior to continuing to provide services to, processing transactions involving, or engaging in other activities with such vessels.

Review All Applicable Shipping Documentation: Individuals and entities processing transactions pertaining to shipments potentially involving petroleum shipments to Syria or involving oil from Iran should ensure that they request and review complete and accurate shipping documentation. Such shipping documentation should reflect the details of the underlying voyage and reflect the relevant vessel(s), flagging, cargo, origin, and destination. Any indication that shipping documentation has been manipulated should be considered a red flag for potential illicit activity and should be investigated fully prior to continuing with the transaction. In addition, documents related to STS transfers should demonstrate that the underlying goods were delivered to the port listed on the shipping documentation.

Know Your Customer: As a standard practice, those involved in the maritime petroleum shipping community, including vessel owners and operators, are advised to conduct Know Your Customer (KYC) due diligence. KYC due diligence helps to ensure that those in the maritime petroleum shipping community are aware of the activities and transactions they engage in, as well as the parties, geographies, and country-of-origin and destination of the goods involved in any underlying shipments. This includes not only researching companies and individuals, but also the vessels, vessel owners, and operators involved in any contracts, shipments, or related maritime commerce. Best practices for conducting KYC on a vessel includes researching its IMO number, which may provide a more comprehensive picture of the vessel’s history, travel patterns, ties to illicit activities, actors, or regimes, and potential sanctions risks associated with the vessel or its owners or operators.

Clear Communication with International Partners: Parties to a shipping transaction may be subject to different sanctions regimes depending on the parties and jurisdictions involved, so clear communication is a critical step for international transactions. Discussing applicable sanctions frameworks with parties to a transaction can ensure more effective compliance.
Leverage Available Resources: There are several organizations that provide commercial shipping data, such as ship location, ship registry information, and ship flagging information. This data should be incorporated into due diligence best practices, along with available information from OFAC as outlined below in the “Syria Sanctions Resources” section of this advisory.

Insurance: There is sanctions risk related to the provision of underwriting services or insurance or reinsurance to certain Syrian and Iranian maritime-related persons or activity.

Consequences of Violating U.S. Sanctions or Engaging in Sanctionable Conduct

Individuals and entities engaged in shipping-related transactions or transfers destined for the Government of Syria or its controlled entities or instrumentalities, or certain transactions involving petroleum or petroleum products from Iran or certain Iran-related persons on the SDN List, should be aware that engaging in such conduct may result in designation or other sanctions under U.S. sanctions authorities unless an exception applies.

In addition, violations of the ITSR or SSR could result in civil enforcement actions or criminal penalties for persons or transactions subject to U.S. jurisdiction.

Persons that violate the ITSR or SSR can be subject to significant civil monetary penalties. [4] OFAC investigates and enforces violations of its regulations as outlined in its Economic Sanctions Enforcement Guidelines, 31 C.F.R. part 501, Appendix A. For more information regarding civil monetary penalties and other administrative actions taken by OFAC, see the Civil Penalties and Enforcement Information portion of OFAC’s web site.
