Embalming Requirements and Zinc-Lined Caskets for Brazil Repatriation

Airlines don't accept a body in a standard wooden coffin on an international flight. Shipping human remains from Brazil to the United States requires a specific combination of chemical preservation, sealed metal containment, and rigid outer packaging — all governed by IATA regulations and individual airline cargo policies. Get any of it wrong and the shipment gets rejected at the cargo terminal.

Embalming Standards for International Transport

Brazilian sanitary regulations require embalming to begin within 24 hours of death if modern refrigeration facilities aren't available at the location where the body is held. For international transport, the embalming must meet a higher standard than domestic Brazilian burial preparation.

A licensed Brazilian embalmer or mortuary physician performs the chemical arterial preservation required for international shipment. This is more extensive than preparation used for some local dispositions.

After embalming, the embalmer issues a formal Embalming Certificate (Certificado de Tanatopraxia) confirming that chemical arterial preservation was completed and identifying the licensed provider.

This certificate travels with the body in the document pouch attached to the outside of the shipping container. Airlines, customs authorities at both ends, and the receiving US funeral home all require it. Without the certificate, the shipment doesn't clear export at the Brazilian airport.

The Zinc-Lined Inner Casket

The body must be placed inside a hermetically sealed zinc- or lead-lined inner casket. This requirement exists to prevent any fluid, gas, or odor from escaping during the pressurized cabin environment of an international flight.

The casket must be sealed in accordance with the carrier's requirements to prevent fluid, gas, or odor leakage during transport.

Standard wooden caskets used for Brazilian funerals and burials don't have zinc linings. The international-transport casket is a specialized product that the funerária either stocks or orders from a supplier. This is one of the major cost components of repatriation — zinc-lined caskets run $1,500–$3,000 depending on the city and the supplier.

Some funeral homes in smaller Brazilian cities don't stock zinc-lined caskets at all. If the death occurs in a rural area or a city without international repatriation experience, the funerária will need to source the casket from São Paulo or Rio de Janeiro and transport it to the preparation site, adding both cost and time.

The Outer Airtray or Wooden Shipping Crate

Once the body is sealed inside the zinc-lined casket, that casket goes inside a rigid outer shipping container. Airlines accept two types:

Wooden shipping crate. A purpose-built wooden box with sufficient structural rigidity to support the combined weight of the body and zinc casket. The crate must have a minimum of six sturdy carrying handles for ground crew handling.

Heavy-duty cardboard airtray. A reinforced corrugated container designed specifically for air transport of human remains. Airtrays are lighter and cheaper than wooden crates but must be new — used airtrays are strictly prohibited by most airlines. The airtray must also have six handles and pass a structural integrity check.

The outer container must be clearly labeled with:

• The air waybill (AWB) number
• The full name of the deceased
• The final destination address in the United States
• "HUMAN REMAINS" identification per carrier and IATA handling requirements

All transport documents — the death certificate, embalming certificate, consular mortuary certificate, police transit permit, and export authorization — go in a secure document pouch affixed to the outside of the container. Cargo handlers and customs officials need to access this paperwork without opening the container.

What Airlines Actually Enforce on Brazil-US Routes

The major carriers operating cargo service between Brazilian airports and the US — LATAM, American Airlines, and United — each have their own human remains handling policies layered on top of IATA baseline requirements.

Common enforcement points:

• Known Shipper status. Only a registered, accredited shipping agent (typically the funerária or a specialized logistics company) can book human remains as international air cargo. Families cannot book this directly.
• Advance booking. Human remains cargo requires advance notice. The airline's cargo desk must confirm space availability and assign the shipment to a specific flight.
• Weight and dimensions. The combined package must fit within the airline's cargo hold dimensions. Oversized caskets may require rerouting to a widebody aircraft.
• Temperature-controlled hold. Some airlines place human remains in a temperature-controlled section of the cargo hold. This is standard on long-haul routes but may limit which flights are available.

The departure airports that handle the most human remains cargo from Brazil are São Paulo-Guarulhos (GRU) and Rio de Janeiro-Galeão (GIG) — both have established cargo facilities with staff experienced in HUM shipments. Deaths in other cities require an overland transfer of the casketed remains to one of these hubs, which adds transit time and cost.

The Document Package That Travels With the Body

The sealed container's external document pouch must include:

1. The apostilled and translated Certidão de Óbito (civil death certificate)
2. The Consular Mortuary Certificate from the US Embassy or Consulate
3. The Embalming Certificate
4. The Civil Police transit permit (Guia de Trânsito)
5. The Federal Police export authorization (Autorização de Embarque)
6. The air waybill

Missing any one of these documents can hold the shipment at the airport cargo terminal for days while the funerária scrambles to obtain it. The Federal Police export authorization, issued at the airport itself, is the final checkpoint — the body doesn't load onto the aircraft until that stamp is in place.
