The UK Office of Financial Sanctions Implementation (OFSI) has released statutory guidance on the Iran nuclear sanctions regime as of May 1, 2026. This guidance provides definitive interpretation of the UK's legal obligations and prohibitions relating to Iran nuclear sanctions.
Scope and Application
The guidance sets out the purposes, scope, and prohibitions of the Iran nuclear sanctions regime under UK law. All persons and entities subject to UK jurisdiction—including shippers, freight forwarders, and exporters—must comply with the restrictions outlined in this statutory guidance.
The regime applies to transactions, goods movement, and financial services connected to Iran's nuclear programme and related activities. Breaches carry civil and criminal penalties, including asset freezes, licensing denials, and substantial fines.
Who Is Affected
Commercial actors in the supply chain are directly affected:
- E-commerce merchants sourcing from or shipping to Iran
- Freight forwarders handling Iran-destined cargo
- Exporters of dual-use goods or technology with nuclear applications
- Financial institutions facilitating payments related to Iran trade
The guidance applies regardless of whether the transaction itself crosses UK territory; extraterritorial reach extends to UK persons and entities wherever located.
Key Compliance Requirements
While the source does not detail specific prohibited goods or thresholds in this summary, shippers must:
- Screen all counterparties, end-users, and beneficial owners against OFSI's consolidated sanctions list
- Verify that no transaction involves designated persons or entities
- Obtain legal advice before proceeding with any Iran-related trade
- Maintain records of due diligence and sanctions screening
What This Means for Shippers
Stop all Iran-destined shipments immediately unless you hold a specific UK OFSI licence—which is rare and difficult to obtain. Screen every counterparty and consignee against the consolidated sanctions list in real time. The cost of proceeding without compliance is civil recovery of profits, criminal prosecution, and debarment from future UK and allied trade. Review the full statutory guidance now and engage legal counsel to confirm your transaction structure before booking cargo.
