Every European company that has ever sourced from Iran runs into the same wall at the same moment. The product is agreed, the specification is signed, the freight forwarder has quoted, and then someone asks the question that stops the deal: how does the supplier actually get paid?
The honest answer is that there is no single channel. There is a set of partial channels, each with its own legal basis, cost, speed, and paperwork burden, and the workable route depends on what you are buying, who your bank is, and how much compliance evidence you are willing to produce. Most of the bad outcomes in this trade — frozen funds, closed bank accounts, cancelled shipments — come from companies picking a channel because someone told them it works, without understanding what it is or what it requires from them.
This article maps the channels that exist in 2026, what each one is actually for, and the evidence file you need to keep regardless of which route you use. It is not legal advice. It is a working map so you can ask your bank and your lawyer better questions.
Why the Obvious Route Is Closed
Direct bank-to-bank transfer is not on the table for most transactions.
The EU maintains restrictive measures against Iran, and a significant number of Iranian financial institutions are listed. Where an entity is listed, EU persons are prohibited from making funds or economic resources available to it, directly or indirectly. That prohibition does not care whether your product is a sanctioned item — it attaches to the counterparty, not the cargo.
The practical consequence is that even where a transaction is lawful, the correspondent banking chain that would normally carry a payment from a German account to a Tehran account does not exist in usable form. Correspondent banks in the chain apply their own risk appetite on top of the law, and that appetite is close to zero. This is the distinction that catches people out:
- Legal means the transaction is permitted under EU regulation
- Bankable means an actual bank will process it
A transaction can be entirely legal and completely unbankable. Banks de-risk. A €40,000 payment for food-grade packaging is not worth the compliance review hours to a mid-size European bank, so they decline it and no one is breaking any law. If you are planning around “it’s legal so it will go through,” you are planning around the wrong test.
Check the counterparty before anything else.
Before you discuss price, run the supplier, its parent, its bank, and its known beneficial owners against the EU Sanctions Map. It is the official consolidated view maintained at EU level and it is free. If any of those names appear, stop — you are not solving this with a clever payment structure. Our sanctions map for EU B2B operators covers this screening step in detail.
The Channels That Actually Exist
1. Third-country intermediary banking.
The most common route in practice. The payment goes from your EU account to a bank in a third country that maintains a working relationship with Iranian institutions — historically Turkey, the UAE, and to a lesser degree China. The intermediary settles onward.
- Works when: your goods are non-sanctioned, your counterparty is unlisted, and the intermediary is a real regulated entity with real disclosure
- Cost: typically the widest spread of any channel; you pay both an FX margin and an intermediation fee, and both are negotiable but rarely disclosed properly
- The trap: you are relying on the intermediary’s compliance, not your own. If they are moving funds for parties you would never touch, your money is in that pipe. Ask for their licence, their regulator, and their AML policy in writing. If they hesitate, that is your answer.
2. Humanitarian and permitted-goods channels.
Food, agricultural commodities, medicine, and medical devices sit in a different category. Mechanisms have existed specifically to allow these flows with heightened due diligence — the Swiss Humanitarian Trade Arrangement being the best-known structured example. These channels are slow and document-heavy by design, because the documentation is the entire point: the bank is buying certainty that the goods are what you say they are.
- Works when: your product genuinely sits in the humanitarian category and you can prove it with certificates, HS codes, and end-user declarations
- Cost: lower FX cost than intermediaries, higher administrative cost
- The trap: stretching the definition. A component that goes into a medical device is not a medical device. Banks classify by HS code and end use, not by your description.
3. Netting and offset structures.
If you both buy from and sell to the same market, you can in principle net the flows so that less cash crosses the border. A European firm importing from Iran and exporting services or goods back can settle the difference rather than the gross.
- Works when: you have genuine two-way trade and both legs are documented as separate arm’s-length transactions
- Cost: the cheapest channel per euro moved, because most euros do not move
- The trap: netting arrangements that are not properly documented look exactly like structuring to a compliance officer. Each leg needs its own contract, its own invoice, and its own commercial logic. If the only reason the second leg exists is to cancel out the first, do not do it.
4. Non-monetary settlement.
Settlement in goods, or against a service delivered locally. Rarer, slower, and only viable where both parties have something the other actually needs. It comes up more often than outsiders expect in commodity trades.
What about INSTEX?
INSTEX — the Instrument in Support of Trade Exchanges set up by France, Germany, and the UK — is the mechanism everyone still asks about. It was wound down in 2023 after processing very little volume. It is not an option. Anyone offering you access to it is not someone you should be transacting with.
The Cost You Are Actually Paying
Nobody quotes you the real number.
The headline in these channels is never the cost. When an intermediary quotes “2%,” ask what that 2% is on top of — and against which reference rate.
The components you should be pricing separately:
- The reference rate. Which rate is the conversion struck at, and who publishes it? The ECB euro reference rates are published daily and are the natural benchmark for the EUR leg. If your counterparty will not benchmark against a published rate, the spread is wherever they want it to be.
- The intermediation fee. Stated as a percentage, charged on gross.
- The timing risk. Days between your payment leaving and the supplier confirming receipt. In these channels that is measured in days to weeks, not hours, and the rate moves in the gap.
- The failure cost. The probability the payment bounces back and you pay both legs of the FX conversion for nothing.
That last one is the number people forget. A 2% channel that fails one time in ten is not a 2% channel. Our piece on FX risk for B2B importers covers how to structure contracts so the timing gap does not land entirely on you.
Price the contract, not the transfer.
The lever that matters more than channel selection is what currency the contract is written in and who carries the conversion risk. If the contract is in EUR and the supplier converts at their end, the FX exposure is theirs. If it is in USD, you have added a currency neither party uses domestically and a compliance layer that comes with US dollar clearing — usually the worst of both.
The Evidence File — What to Keep and Why
Assume you will be asked to explain the transaction two years later.
Not by a regulator, necessarily. More likely by your own bank, during a periodic review, when a compliance analyst who has never met you looks at a payment to an entity in Dubai and asks what it was for. If you can answer in one email with attachments, the account survives. If you need three weeks to reconstruct it, the account often does not.
For each transaction, keep in one folder:
- The signed contract with a clear description of goods and Incoterms
- The commercial invoice and packing list
- HS classification for every line item, with your reasoning if it is not obvious
- The end-user declaration
- Bill of lading or air waybill
- Certificate of origin
- Screening results for the counterparty, dated, against the EU consolidated list
- The payment instruction and the intermediary’s confirmation
- Your internal note explaining why this channel was chosen
The internal note is the item people skip and the one that matters most. It is a paragraph. It says: we screened X on date Y, found no listings, product is HS code Z which is not restricted, we used channel A because B, and here is who approved it. That paragraph is the difference between a documented commercial decision and an unexplained payment.
Incoterms selection interacts directly with this, because the term determines who holds title and risk at the moment money moves. Incoterms for EU–Iran B2B trade breaks that down.
Practical Rules That Save Deals
Talk to your bank before you sign, not after. Most European banks have a trade finance desk that will tell you, informally, whether a transaction is something they will process. That conversation costs you an hour. Finding out after the goods have shipped costs you the shipment.
Never split a payment to stay under a threshold. Structuring is an offence in itself in most EU jurisdictions, and it is the single fastest way to convert a legal transaction into a criminal one. If a payment is too large for a channel, use a different channel or a different counterparty.
Do not accept a channel you cannot describe. If your supplier says “send it to this account in Dubai and it will be handled,” you do not have a channel — you have a hole. Ask who owns the account, what their licence is, and what the money does after it arrives. A legitimate intermediary answers those questions in writing.
Build in the timing. Payment confirmation in these routes takes days. Contracts that make delivery contingent on same-week payment confirmation will fail on timing alone and both sides will blame each other for something neither controls.
Re-screen before every payment, not once per relationship. Listings change. A counterparty that was clean in March may not be in September. The screen takes two minutes and it is dated evidence in your file.
The uncomfortable truth about this trade is that the payment channel is usually harder than the product, the freight, and the customs clearance combined — and it is the part most companies plan last. Reversing that order is the single highest-value change you can make. Decide how the money moves before you agree what you are buying, because the channel determines what volumes, what currencies, and what timelines are realistic, and everything else has to fit inside those constraints.
If you take one thing from this: the goal is not to find the clever route. It is to find the boring, documented, explainable route that your own bank will still be comfortable with in two years. That route is slower and costs more than the one someone will offer you on WhatsApp. It is also the only one where you still have a company at the end.
