If your company has commercial, financial or logistical relationships with Iran, this regulation affects you right now. The Decision (CFSP) 2026/1837, adopted on 24 July 2026 and published on 27 July, expands the sanctions regime established in 2023 against Iran, incorporating new natural and legal persons into the EU's restrictive measures lists.
The regulation does not create a new regime: it amends and tightens the one already in place since the Decision (CFSP) 2023/1532, which responded to Iranian supply of drones and weapons to Russia for use in Ukraine. This new decision also expands the scope to Iranian support for armed groups in the Middle East and the Red Sea, and actions that undermine freedom of navigation in the region.
What does this regulation establish?
Decision (CFSP) 2026/1837 expands the list of persons and entities subject to restrictive measures within the EU's sanctions regime against Iran. The two specific measures applied to the new listings are:
- Asset freezing: all funds and economic resources belonging to the listed persons and entities are blocked. No European company may make funds or economic resources available to these entities, directly or indirectly.
- Prohibition of travel to the EU: natural persons included in the list cannot enter or transit through the territory of the Member States of the European Union.
The reasons justifying the new additions to the list are as follows:
- Iranian supply of drones and weapons to Russia for use in the war of aggression against Ukraine.
- Support for Hezbollah, the Houthis and other militias that destabilize the Middle East and the Red Sea.
- Iranian actions that undermine freedom of navigation in the Middle East.
This decision is framed within European Regulation on common foreign and security policy (CFSP), which means it is directly applicable in all Member States, including Spain, without need for transposition.
Economic and operational impact
The impact is not only geopolitical: it has direct operational consequences for any company with exposure to Iran or entities linked to the listed parties.
| Area of impact | Concrete consequence |
|---|---|
| Payments and collections with Iranian counterparties | Obligation to verify that no counterparty appears on the updated list before executing any transaction |
| Contracts in force with Iranian entities | If the counterparty appears on the list, the contract is de facto blocked: no deliveries, payments or services can be performed |
| Financial operators | Especially exposed: must update their customer and counterparty screening processes with the new list |
| Transport and logistics operators | Restrictions on assets and movements directly affect routes and operations in the Red Sea and Middle East |
| Non-compliance | Administrative and criminal sanctions according to the legislation of each Member State |
The risk is not limited to companies operating directly with Iran. Any company that, unknowingly, maintains relationships with an entity that is in turn linked to sanctioned persons or companies may incur liability. This is why counterparty screening is the priority action.
Who does it affect?
- Export and import companies with commercial activity in Iran or with Iranian intermediaries.
- Financial and banking entities that process payments, financing or guarantees linked to Iranian counterparties.
- Logistics and maritime transport operators with routes in the Red Sea, the Persian Gulf or the Middle East.
- Insurance and reinsurance companies that cover operations in the region.
- Legal advisors, consultancies and commercial agents acting as intermediaries in operations with Iran.
- CFOs and compliance departments of any business group with subsidiaries or partners in the region.
Practical example
A Spanish industrial machinery company has a distributor in Dubai who in turn resells some of its products to customers in Iran. Following the publication of Decision (CFSP) 2026/1837, the compliance department must verify whether any of the final Iranian customers of that distributor—or the distributor itself—appears on the updated list of sanctioned persons and entities.
If any of those entities appear on the list, the Spanish company cannot continue supplying products to that distributor for those destinations, even though the direct relationship is with a company in Dubai. The entire supply chain is affected. Failure to act may result in administrative sanctions and, depending on applicable Spanish legislation, even criminal liability.
The immediate action is to cross-reference the database of customers, suppliers and partners with the official updated list published in the EU Official Journal.
What should companies do now?
- Review the updated list of sanctioned parties immediately: access the updated version of the Iran sanctions regulation in the EU Official Journal and identify whether any commercial or financial counterparty appears on it.
- Audit active contracts with Iranian links: review all active contracts with customers, suppliers, distributors or intermediaries operating in Iran or in the Red Sea and Middle East region.
- Update compliance screening processes: incorporate the new list into counterparty verification systems, especially in financial entities and logistics operators.
- Preventively block ongoing operations with counterparties that have not been verified until the review is complete.
- Consult with specialized legal advisors if there is indirect exposure through supply chains or distribution structures in third countries.
- Document all actions taken: in case of inspection or investigation, traceability of the compliance process is the main defense against administrative or criminal sanctions.
Frequently asked questions
Where can I consult the updated list of persons and entities sanctioned by the EU in relation to Iran?
The official list is published in the Official Journal of the European Union, specifically in the annex to Decision (CFSP) 2026/1837 and its amendments. It can also be consulted through the EU sanctions search tool available on the European Commission portal.
What happens if my company operates with an Iranian entity that I didn't know was sanctioned?
Lack of knowledge does not exempt from liability. Sanctions for breach of the restrictive regime can be administrative and criminal, according to the legislation of each Member State. This is why it is mandatory to implement screening processes prior to any operation with Iranian counterparties or those linked to the region.
When do these new sanctions come into force?
Decision (CFSP) 2026/1837 entered into force on 24 July 2026, although it was published in the EU Official Journal on 27 July 2026. The measures are directly applicable in all Member States from that date.
Do these sanctions only affect companies operating directly with Iran?
No. Sanctions may also affect companies operating with intermediaries in third countries (such as the United Arab Emirates, Turkey or others) if those intermediaries are linked to persons or entities included on the list. The entire supply chain must be verified.
Which sectors are especially exposed to these sanctions?
According to the regulation itself, financial operators and transport operators are especially exposed given the scope of restrictions on assets and movements. Export companies, logistics operators with routes in the Red Sea and Middle East, insurers and any company with distributors in the region are also at risk.
