Iran sanctions snapback raises global compliance risks
Law360, Expert analysis: On 27 September 2026, the United Nations (UN) Security Council reimposed the full gamut of UN sanctions targeting Iran's nuclear proliferation program, doing so by operation of a so-called snapback mechanism. John Sandage, of counsel at Berliner Corcoran & Rowe LLP, discusses the implications of this development, noting how the reimposed sanctions, along with additional EU and UK measures, signal renewed international pressure on Iran. He highlights the broad scope of these sanctions and the heightened compliance challenges they pose for US and non-US companies, warning that expanded enforcement and secondary sanctions risks will require greater vigilance and due diligence.
