This guide is informational and educational only. It is not legal or medical advice. Requirements change and clinic policies differ, so confirm the details for your own transfer with your clinic and the receiving clinic in Iran.
The Iran Route, in Plain Terms
Moving embryos from the UK or Europe to a clinic in Iran is a well-travelled route, and a more straightforward one than many people expect. Families choose it for many reasons, often closeness to relatives or the familiarity of treatment in a country they know. Whatever your reason, the logistics follow the same clear path, and that path is what this guide walks you through.
The flight is the easy part. The documentation is what needs care and time. Get that right, and the journey itself is routine.
The Documents You Need
An international transfer to Iran rests on a set of documents prepared in advance. The sending clinic applies for an export licence through the relevant authority, and that licence must name the courier carrying the embryos. The receiving clinic in Iran provides an agreement confirming it will accept the material. For airport security at both ends, no X-ray letters are prepared so the tank is inspected by hand rather than scanned. And for the destination, a customs release letter is arranged so the tank can be cleared on arrival.
If the route includes a stopover, every transit point is addressed in the paperwork too. We coordinate this whole pack alongside both clinics, which is why the earlier we start, the smoother it runs.
Export licence naming the courier, import clinic agreement, no X-ray letters for both airports, and a customs release letter for the destination. Each piece has a purpose, and the journey is only booked once they are in hand.
The Journey Itself
On the day, a UN3373-qualified courier collects your embryos from the sending clinic in a cryogenic tank that holds minus 196 degrees, the temperature of liquid nitrogen vapour, for far longer than the journey takes. The embryologist verifies the embryos against your records before they are loaded. The courier then carries the tank in the aircraft cabin, never in cargo, on routes typically served by carriers such as Turkish Airlines, Emirates or Qatar Airways, depending on the connection.
The tank stays with the courier the entire way. On arrival in Iran, the receiving clinic uses the pre-arranged customs documentation to clear it, and the embryologist verifies the embryos and the condition of the vessel before they go into storage. We keep you updated as the embryos travel, so you always know where they are.
How Long It Takes
Plan for several weeks, not several days. The transport is quick once it begins, but the export licence and destination documentation take time to assemble, and they cannot be rushed at the end. The single most useful thing you can do is start the conversation early, before your treatment dates are fixed, so the paperwork moves in parallel with everything else.
What It Costs
Cost depends on the route, the connection and the documentation involved. An international transfer with export licensing and customs coordination costs more than a domestic move, which is to be expected given the work behind it. We give clear, itemised quotes so you can see exactly what you are paying for, with no vague figures and no surprises.
A Factual Note on Sanctions
Because patients ask, we will state it once and plainly. No sanctions apply to the transport of medical biological material such as embryos. The movement to Iran is treated as a medical and logistical matter, handled through the standard export, import and customs documentation for human tissue. We keep all Iran-related guidance strictly factual and confine ourselves to the logistics.
Frequently Asked Questions
Can I transport frozen embryos from the UK to Iran?
Yes. Embryos can be moved from the UK or Europe to a licensed clinic in Iran with the right documentation: an export licence naming the courier, an import agreement, customs release for the destination airport, and airline approval for the tank as cabin baggage.
Do sanctions affect transporting embryos to Iran?
No sanctions apply to the transport of medical biological material such as embryos. It is handled through the standard export, import and customs documentation for human tissue.
How long does it take to arrange?
Allow several weeks. The transport is quick, but the export licence and destination documentation set the timeline. Begin well before your intended treatment dates.
Will my embryos go through an airport X-ray scanner?
No. We prepare no X-ray letters for both airports and arrange manual inspection, so the tank is not scanned. The courier carries it in the cabin and stays with it throughout.
Embryo Links coordinates the export licence, customs release and airline approval, and a UN3373-qualified courier carries the tank in the cabin from collection to delivery. Talk to us about your route to Iran.
