By Australia has an international reputation for clean, high-quality produce. Rock lobster, oysters, premium beef, cherries, berries, native flowers and specialty dairy products all find eager buyers across Asia, the Middle East and beyond. Much of this trade depends on air freight, and Sydney is one of the main gateways for it. Pharmaceuticals and clinical trial materials also move through the city every day under strict temperature rules.
Perishable cargo leaves little room for error. A few hours at the wrong temperature can reduce shelf life, damage quality or make a shipment worthless. This guide explains how temperature-controlled air freight works, how to package perishables and how to plan for a smooth journey. It is part of our wider Air Freight Sydney guide.
What counts as perishable air cargo?
Perishable cargo is anything that deteriorates over time or under the wrong conditions. The most common categories out of Sydney include:
- Seafood, including live lobsters, abalone, oysters and chilled fish
- Meat, especially chilled beef and lamb for premium markets
- Fruit and vegetables, such as cherries, berries, stone fruit and asparagus
- Cut flowers and foliage, including Australian natives
- Dairy and specialty foods, such as cheese, infant formula ingredients and prepared meals
- Pharmaceuticals and life sciences, including vaccines, biologics and diagnostic samples
Understanding temperature ranges
Each product has its own ideal range, and the entire supply chain needs to know it. Common ranges include:
| Range | Typical temperature | Examples |
|---|---|---|
| Frozen | −18 °C or colder | Frozen seafood, meat, some biological samples |
| Chilled | 0 to 4 °C | Fresh fish, oysters, chilled meat |
| Cool | 2 to 8 °C | Most vaccines, many medicines, some fruit |
| Controlled room temperature | 15 to 25 °C | Many tablets and some medical products |
| Live | Species-specific | Live lobsters and crabs, which need cool, humid conditions |
Airlines and terminals use standard temperature codes on bookings and labels so that everyone handling the cargo knows what is required. Include the exact range on your booking, air waybill and package labels.
Packaging options
Passive packaging
Passive systems keep products at the right temperature without power. They include insulated polystyrene boxes, thermal liners and blankets, gel packs, ice and dry ice. Passive packaging is used for most food exports because it is cost-effective and flexible. The key is to choose packaging rated for the full journey time, plus a buffer for delays.
Active containers
Active containers have their own cooling or heating systems powered by batteries or other sources. They are used for high-value pharmaceuticals and other goods that must stay within a tight range. Specialist providers lease these units to shippers, and airlines charge special handling fees for them.
Dry ice
Dry ice is excellent for keeping goods frozen, but it is classed as a dangerous good for air transport. Packages must allow the gas to vent and be labelled with the net weight of dry ice. Our guide to packaging and declaring dangerous goods for air transport explains the requirements.
Export requirements for food and agricultural products
Most food and agricultural exports from Australia are regulated by the Department of Agriculture, Fisheries and Forestry. Depending on the product and destination, you may need:
- An export-registered establishment for preparing the goods
- An export permit issued through the department's export documentation system
- A health certificate or phytosanitary certificate for the destination market
- Compliance with the importing country's specific conditions, such as residue limits or labelling
The department's country requirements tell you what each market expects. Allow time for inspections and certificates before the flight. Our guide to the step-by-step export process from Sydney shows where these requirements sit in the wider export timeline.
Handling at the terminal
Sydney's cargo terminals include cold rooms and freezers for perishable cargo, and many handlers follow IATA's Perishable Cargo Regulations. For pharmaceuticals, the IATA Temperature Control Regulations and certification programs such as CEIV Pharma help ensure consistent handling. For fresh food, the CEIV Fresh program serves a similar purpose.
When choosing an airline or forwarder, ask:
- Does the terminal have cold storage for your temperature range?
- How is cargo moved between the cold room and the aircraft, and how long does it wait on the tarmac?
- Are staff trained in perishable and pharmaceutical handling?
- What happens if the flight is delayed or cancelled?
Cold storage at terminals is usually charged at a higher rate than general storage and may have a shorter free period. Our guide to storage fees at Sydney air cargo terminals explains how these charges work.
Timing is everything
For perishables, the fastest route is not always the one with the shortest flight time. Consider the whole journey:
- Pack as close to departure as possible, while leaving enough time for inspections and lodgement.
- Prefer direct flights. Each transfer adds handling time and temperature risk.
- Avoid weekend arrivals where the destination's customs or food inspection services work reduced hours.
- Check local holidays in the destination country, such as Lunar New Year in North Asia.
- Build in a buffer for delays, especially in summer when heat on the tarmac is a bigger risk.
Monitoring the cold chain
Temperature data loggers record conditions throughout the journey. Some newer devices send live temperature and location data, allowing you to act quickly if something goes wrong. Loggers also provide evidence if you need to make an insurance claim or resolve a dispute with a buyer. Our guide to air freight tracking tools covers devices and platforms that combine location and condition monitoring.
Costs to expect
Temperature-controlled air freight costs more than general cargo. Expect higher rates or surcharges for perishable handling, cold storage, active container rental, dry ice and special documentation. Because perishable products often have high value and short shelf lives, these costs are usually justified by the price premium in the destination market.
For some chilled products with longer shelf life, sea freight in refrigerated containers can be a cheaper alternative. Our comparison of air freight and sea freight from Sydney can help you weigh the options.
Common mistakes to avoid
- Choosing packaging rated for the flight time but not the full door-to-door journey
- Leaving out the temperature range on bookings and labels
- Pre-cooling products inadequately before packing
- Missing export certificates or making errors on them
- Shipping late in the week to markets with limited weekend services
- Forgetting to declare dry ice
Preparing a perishable shipment: a checklist
- Confirm the product's temperature range and maximum time out of refrigeration.
- Check the destination country's import conditions and the certificates required.
- Book with a forwarder and airline experienced in perishable cargo, specifying the temperature range.
- Choose packaging rated for the full door-to-door journey plus a buffer.
- Pre-cool the product and the packaging before packing.
- Add a temperature logger and record its serial number.
- Label every box with handling instructions, temperature range and, if used, dry ice details.
- Prepare the commercial invoice, packing list, export permit and health or phytosanitary certificate.
- Deliver to the terminal close to the cut-off time to reduce waiting.
- Send documents and flight details to the buyer so they can arrange prompt collection.
Importing perishables into Sydney
The same principles apply in reverse for importers. Fresh produce, seafood, flowers and medicines arriving in Sydney must pass biosecurity and, for food, imported food inspection before release. Delays at this stage are especially costly for perishables, so check import conditions in advance, send documents early and make sure your cold storage and transport are ready the moment the goods are cleared. Our beginner's guide to Australian customs explains the clearance process.
Frequently asked questions
What is the difference between passive and active packaging?
Passive packaging keeps goods cool using insulation and refrigerants, with no power source. Active containers have their own powered cooling or heating and can hold a precise temperature for longer, but they cost more.
Who pays if a perishable shipment spoils?
It depends on the cause, the Incoterm and your insurance. Carrier liability is limited, so many exporters of perishables take out cargo insurance and use temperature loggers to show where a problem occurred.
How long can chilled seafood travel by air?
It depends on the product, packaging and temperature control. Many chilled seafood shipments from Sydney reach Asian markets within a day, while longer routes need more robust packaging and careful planning.
Do I need a specialist forwarder for perishables?
For regular or high-value perishable exports, a forwarder with dedicated perishable experience is strongly recommended. They understand certificates, cold storage and airline requirements.
It also pays to build a relationship with the ground handler and airline on your main routes. Regular perishable shippers who communicate volumes and timings in advance are more likely to secure space in peak periods and receive priority handling when something goes wrong. Share your forecasts, invite feedback on packaging and review temperature data from past shipments together.
