Failure to comply with the complex web of US sanctions laws and regulations carries significant risks both in terms of exposure to civil fines and penalties and reputational harm. To help maritime sector stakeholders navigate these regulations, the US Department of Treasury’s Office of Foreign Assets Control (OFAC) has published scenario-based sanctions compliance guidance on October 31, 2024, to aid commodities brokers, insurers, ship management service providers, shipbroking companies, port authorities and other industry participants to identify attempts at sanctions evasion, address due diligence issues and implement best practices. This guidance supplements OFAC’s previously published guidance related to the maritime sector, including the May 14, 2020 “Sanctions Advisory for the Maritime Industry, Energy and Metal Sectors, and Related Communities.”
