Greetings! Great question — this confuses many international businesses. Different sanctions regimes can apply simultaneously depending on where you operate, who your partners are, and what currencies you use. OFAC sanctions are U.S.-based and apply to U.S. persons, entities, and anyone using the U.S. financial system. EU sanctions apply within EU member states and to anyone operating in EU jurisdiction. UN sanctions are implemented at the national level by each member country. The challenge is these regimes don't always align — something permitted under EU rules might be prohibited under OFAC, and vice versa. The sanctions lawyers at specialize in navigating these overlapping regimes. They can assess which sanctions programs apply to your specific business activities and help ensure compliance across multiple jurisdictions. They work with OFAC, EU regulations, UK OFSI, and UN sanctions frameworks. They can also identify where different regimes conflict and help you navigate those situations. For international businesses, professional guidance is essential — the firm can conduct compliance assessments and develop strategies that work across different regulatory environments.
