Since September 27, 2025, UN snapback sanctions against Iran have been fully in force. The EU reimposed restrictions across steel, metals, energy, banking, and dual-use goods. In May 2026, the Council extended the legal framework to cover entities involved in Hormuz navigation disruption. US OFAC, operating on a separate track, expanded its “Economic Fury” campaign. The UK, post-Brexit, maintains its own autonomous regime broadly aligned with the EU but with distinct timing and scope.
For EU-based B2B operators who have historically worked the Iran corridor — or who source from Iranian suppliers — the question is no longer whether sanctions exist. The question is which exact categories are restricted and which remain legal. The answer is layered, and getting it wrong carries criminal and civil exposure in multiple jurisdictions simultaneously.
This article maps the current landscape layer by layer. It is operator awareness — not legal advice. Consult qualified sanctions counsel before any Iran-adjacent transaction.
The Three Layers: EU, OFAC Secondary, UK Sanctions
Understanding Iran sanctions in 2026 requires keeping three regimes distinct. They overlap substantially, but their scope, enforcement mechanisms, and exceptions differ in ways that matter.
EU sanctions (Council Regulation (EU) No 267/2012, as reinstated September 2025)
The EU framework was suspended under the Joint Comprehensive Plan of Action (JCPOA) and then reinstated following the snapback mechanism invoked by France, Germany, and the United Kingdom in September 2024. Full effect occurred on September 27, 2025. The reinstated measures cover: nuclear-related goods and technology, oil and petrochemicals, metals and steel, arms and dual-use goods, financial and banking restrictions targeting designated entities, and shipping and transport services where the beneficial owner is designated.
The May 2026 Council extension added a specific category: entities involved in Iran’s actions “impeding lawful transit passage and freedom of navigation.” This is a direct response to Strait of Hormuz disruption and creates exposure for shipping companies, logistics intermediaries, and financial institutions providing services to covered entities — even where the underlying cargo is otherwise permitted.

US OFAC — secondary sanctions
US secondary sanctions operate differently from EU primary sanctions. They do not prohibit EU companies from transacting with Iran in categories the EU permits. They prohibit EU companies from transacting in ways that expose them to the US financial system — and more broadly, they expose non-US entities to US sanctions risk when they deal with designated Iranian entities, regardless of where the transaction occurs. The “Economic Fury” campaign, expanded in May 2026, specifically targets SDN-listed Iranian entities and their non-Iranian business networks. An EU importer working through an intermediary that has indirect ties to a designated Iranian entity may face secondary sanctions exposure — even if the EU-side transaction is technically compliant.
The practical implication: EU operators must screen not just direct counterparties but the beneficial ownership structure behind them.
UK autonomous sanctions
The UK’s Iran sanctions regime, administered under the Iran (Sanctions) Regulations 2023, broadly mirrors the EU position but has operated independently since Brexit. The UK has generally moved in step with EU reimposition, but there are timing and definitional differences. UK-incorporated entities, UK nationals, and UK-flagged assets anywhere in the world are subject to UK sanctions — meaning a Serbian subsidiary of a UK parent, for example, carries UK sanctions obligations on top of EU ones.
What Is Explicitly Prohibited in 2026
Goods and technology
The hard prohibitions as of July 2026 cover the following categories:
- Nuclear materials, equipment, and related technology transfers (absolute prohibition)
- Arms, ammunition, and military equipment — including items on the EU Common Military List
- Dual-use goods listed in Annex I of EU Dual-Use Regulation (EU) 2021/821, where the end-user is in Iran
- Steel, iron, aluminum, and copper — import, export, and transit
- Oil, petroleum products, and petrochemical products — export to Iran, import from Iran
- Gold, precious metals, and banknotes to the Iranian government or Central Bank of Iran
- Luxury goods above defined value thresholds
Services and financing
Service-side prohibitions are often where EU operators face unexpected exposure:
- Investment in Iranian oil, gas, and petrochemical sectors
- Transfer of financial funds to or from designated Iranian entities
- Insurance and reinsurance for prohibited activities
- Provision of technical assistance, brokering services, or financing where the ultimate purpose relates to a prohibited category
- Port and shipping services to Iranian-flagged vessels on the designated list
The May 2026 addition
Entities listed under the Hormuz navigation disruption extension cannot receive any EU services — financial, logistical, technical, or otherwise. The list is maintained by the Council and updated regularly. Operators should run counterparty screening against both the EU Consolidated List and the May 2026 Annex.

What Is Explicitly Permitted — The Humanitarian Exceptions
The sanctions regime includes explicit carve-outs. These are not gray areas — they are legally defined and maintained in the operative regulations.
Food and agricultural goods
Trade in food, agricultural products, and goods for agricultural use is explicitly permitted, including direct export from the EU to Iran and import from Iran. This exception covers grain, animal feed, processed food, and related commodities. It does not cover agricultural dual-use equipment that could be repurposed for prohibited activities.
Medical equipment and pharmaceuticals
Medical devices, medicines, and medical equipment are explicitly permitted. This exception is broadly drafted and covers diagnostic equipment, surgical instruments, pharmaceutical products, and medical consumables. The exception applies regardless of the buyer — government hospitals, private clinics, and commercial distributors are all covered. The practical constraint is banking: even where the goods are permitted, finding a European bank willing to process the underlying payment is increasingly difficult.
Humanitarian aid
Goods intended for humanitarian purposes — food aid, disaster relief materials, and items destined for non-profit organizations operating in Iran — are explicitly permitted. Documentation requirements apply.
Personal remittances
Transfers for the personal use of private individuals — not commercial transactions, not transfers to designated entities — remain permitted. The threshold and documentation requirements vary by member state, but the exception exists in the core regulation.
Pre-existing contracts
A limited wind-down mechanism applies to contracts concluded before the reimposition date (September 27, 2025). These are subject to case-by-case assessment and competent authority authorization in most member states.

The Gray Zone — Goods That Require Case-by-Case Licensing
Between the explicit prohibitions and the clear humanitarian exceptions lies a category of goods and transactions that require individual licensing assessment. This is where most practical compliance questions land.
Dual-use goods with civilian end-use claims
Many industrial goods appear on the EU Dual-Use list but have legitimate civilian applications — telecoms equipment, certain chemical precursors, some electronics. Whether export is permitted depends on: the specific item’s classification under the dual-use regulation, the stated end-user, the credibility of end-use documentation, and the competent authority’s risk assessment in the exporting member state. There is no single EU-level licensing authority — applications go through national authorities (in Germany: BAFA; in the Netherlands: DG Enterprise; in France: SBDU).
Industrial machinery for non-prohibited sectors
Machinery intended for food processing, pharmaceutical manufacturing, or other humanitarian-adjacent sectors may be exported — but where the same machinery could serve prohibited purposes, case-by-case licensing is required. The burden of demonstrating compliant end-use falls on the exporter.
Financial services for permitted activities
This is arguably the most practically difficult gray zone. Banks are permitted to process payments for food, medicine, and humanitarian goods — but many European banks have adopted blanket Iran policies that refuse all Iran-related transactions regardless of category. This is a de-risking decision by private institutions, not a legal requirement. It creates a situation where transactions are legally permitted but operationally blocked.
Shipping and logistics for permitted cargo
Freight and logistics providers may carry permitted goods to Iran. The complication is that vessels, ports, and logistics entities may be subject to separate designations — and the May 2026 extension specifically targets Hormuz-adjacent entities. An operator shipping permitted food goods is still responsible for ensuring the shipping company, the port of loading/discharge, and any intermediary logistics provider are not listed.
Iranian-sourced goods through third-country intermediaries
Goods of Iranian origin that pass through Turkey, UAE, or other third countries and are represented as goods of that country’s origin present trade-fraud risk in addition to sanctions risk. EU customs regulations require accurate origin declarations. An EU importer who knowingly purchases Iranian-origin goods via a Turkish intermediary to circumvent import restrictions faces exposure under both customs law and the sanctions regulation.
For incoterms and documentation obligations in EU-Iran adjacent transactions, the choice of trade term determines where documentary risk sits.
Five Compliance Steps Before Any Iran-Adjacent B2B Transaction
These steps do not constitute a compliance program. They are the minimum floor before executing any transaction that involves Iranian counterparties, Iranian-origin goods, or Iran-adjacent routing.
Step 1 — Screen all counterparties against the EU Consolidated Sanctions List
The EU Consolidated List is maintained by the European External Action Service and updated when new designations are made. Screen legal entity names, beneficial owners, and registered addresses. The May 2026 extension added a new Annex that must be searched separately. Free screening is available at sanctionsmap.eu — cross-reference with OFAC’s SDN list at ofac.treasury.gov.
Step 2 — Classify the goods under EU Dual-Use Regulation (EU) 2021/821
Before any export, confirm whether the goods appear on the dual-use control list. If they do, contact the competent national authority in your jurisdiction for licensing guidance. If they don’t appear on the list, document that classification assessment and retain it. Customs authorities may request it.
Step 3 — Verify the humanitarian exception applies in writing
If your transaction falls under a humanitarian exception (food, medicine, humanitarian aid), document the basis explicitly: the specific regulatory provision, the end-user identity and purpose, and any end-use certificates. The exception is real but it requires documentation to be defensible.
Step 4 — Assess your banking exposure before contracting
Contact your bank before signing a contract. Many European banks will refuse Iran-related payments regardless of legal permissibility. Discovering this after contract execution exposes you to breach of contract claims from your counterparty. If your primary bank declines, specialist trade finance providers exist — but identifying them takes time.
Step 5 — Obtain a legal opinion from qualified sanctions counsel
For any transaction above a material value threshold, a written legal opinion from a sanctions specialist — covering EU, OFAC secondary, and UK exposure — is both good practice and a potential affirmative defense. The cost of the opinion is invariably less than the cost of enforcement or remediation.

This article is operator awareness, not legal advice. The sanctions landscape changes with each Council decision, OFAC update, and enforcement action. The analysis above reflects the regulatory position as of July 2026 — but the designations list, licensing positions, and bank de-risking policies change more frequently than any article can track. Before executing any Iran-adjacent transaction, consult qualified sanctions counsel in your jurisdiction.
