Embalming is one of the most misunderstood aspects of international repatriation. Families frequently receive confirmation that embalming has been carried out without fully understanding what was done, why it was necessary, or what it means for the person they have lost. This article explains the process plainly.
What embalming is
Embalming is the preservation of a body through a combination of arterial treatment and cavity treatment. Arterial embalming involves the circulation of a formaldehyde-based preservative solution through the body’s arterial system, which slows decomposition and sanitises the tissues. Cavity embalming involves the aspiration of gas and fluid from the chest and abdominal cavities and the injection of a concentrated preservative fluid.
Hygienic preparation — washing, dressing, and positioning — accompanies embalming but is distinct from it. Surface treatments can be applied after arterial embalming to restore appearance where there has been trauma or post-mortem change.
Embalming for international repatriation is a higher standard of preservation than domestic embalming carried out for viewing purposes alone. It must withstand the transit period, which may be several days.
Why embalming is required for international repatriation
International air transport of human remains is governed by IATA Resolution 16 (Perishable Cargo Regulations) and by the health authorities of the countries of origin and destination. The requirement for embalming exists for two reasons.
First, public health. A body in early or active decomposition represents a biological hazard in the enclosed environment of an aircraft hold. The embalmed body, sealed in an airtight container, does not present this risk.
Second, legal compliance. The UK and most other countries require an embalming certificate signed by a qualified embalmer before they will accept an inbound body from abroad. The certificate confirms the embalming has been carried out to the required standard by a qualified practitioner. Without this certificate, the body cannot be airfreighted and cannot be accepted by UK customs.
Most countries with any repatriation case volume have qualified embalmers available. In countries with limited funeral infrastructure, a UK repatriation company will often need to arrange for a qualified embalmer to travel to the location.
Who carries out embalming abroad
In the UK, embalming is carried out by qualified embalmers holding certification from the British Institute of Embalmers (BIE) or equivalent. Abroad, the standards and qualifications vary by country. In the EU, most member states have trained embalmers working in funeral homes that handle international cases. In countries with less-developed funeral sectors, embalming may be carried out by a medical professional rather than a specialist embalmer, and the UK company coordinating the case must verify that the standard meets IATA and UK import requirements.
The zinc-lined coffin
Alongside embalming, international repatriation requires the body to be transported in a sealed container that meets specific standards. In most cases, this is a zinc-lined outer container (sometimes called a shell case), which is hermetically sealed around an inner wooden coffin. The zinc lining provides a leakproof seal that contains any fluid and prevents odour escape during the journey.
The zinc-lined container is what airlines carry in their cargo holds. At the UK end, the body is received in this container. If the family wishes to use a different outer coffin for the UK funeral, the body can be transferred from the sealed container into the chosen coffin at the UK funeral home. The zinc container itself is not on display at the service.
What families can expect
Families cannot usually be present for embalming carried out abroad. It takes place in the country of origin, typically at a local funeral home or mortuary facility, before the necessary documentation — including the embalming certificate — is completed.
Where families wish to view the person before the repatriation flight departs, this must be specifically arranged and depends on local facility availability and on the timelines involved. This is not always possible for logistical reasons.
On arrival in the UK, the body remains in the sealed container until released to the funeral director appointed by the family. At that point, the family can request a viewing if they wish.
Religious considerations
Some religious traditions have concerns about embalming. Jewish halachic law generally prohibits embalming; Islamic tradition strongly prefers the body not to be treated in this way. In practice, where the country of origin requires embalming as a legal condition of export, there is limited ability to exempt a body from this requirement. UK repatriation coordinators are familiar with this tension and can advise on what is and is not possible in specific countries.
Key points
- Embalming for international repatriation is required by IATA regulations and most national health authorities.
- It is carried out to a higher standard than domestic embalming.
- An embalming certificate signed by a qualified embalmer is a mandatory export document.
- The body travels in a hermetically sealed zinc-lined container.
- Families can request transfer to a preferred coffin at the UK funeral home after arrival.
