How to Ship Perishable Goods from Thailand by Air: A Buyer's Plan

Start with the product, not the flight

Perishable is a broad label. Fresh mangosteen, chilled seafood, cut orchids, frozen ready meals and probiotic drinks all travel by air from Thailand, yet each has a different temperature range, shelf life and tolerance for handling. Before you ask anyone for a freight quote, write a one-page product profile. It will save you from quotes that cannot be compared and from a forwarder guessing on your behalf.

Your profile should cover:

• **Temperature band**: frozen, chilled, or cool ambient. Ask the supplier for the range the product must stay within, not just a single target number.
• **Remaining shelf life at dispatch**: how many days the product has left when it leaves the packing house, and how many you need on arrival to sell it.
• **Sensitivity**: does it bruise, leak, give off ethylene or odour, or need ventilation? Some fruit should not travel next to other fruit.
• **Regulatory category**: fresh produce, animal product, processed food or live plant. This decides which certificates and inspections apply at both ends.

The point of this exercise is honest arithmetic. Add up door-to-door transit, a realistic buffer for a missed connection, and the selling window you need. If the numbers leave no margin, air freight alone will not rescue the plan. You may need a different product form, such as frozen instead of fresh, or a destination with a direct flight. It is much cheaper to learn this on paper than from a rejected shipment.

Choose the right air service and routing

Air freight is not one product. For perishables you are usually choosing between general cargo with your own passive packaging, an airline's dedicated perishable or cool-chain service, and an express courier for very small parcels. Each has trade-offs.

• **General cargo with insulated packaging**: the most widely available option and usually the lowest freight rate. The cargo depends entirely on your box, gel packs or dry ice, because it may wait on the apron or in a non-chilled warehouse.
• **Airline perishable service**: priority handling, access to cool rooms at origin and sometimes at transit and destination. It costs more, and what is actually included differs by airline and airport, so ask for the handling description in writing.
• **Express courier**: simple door-to-door for samples and small trial orders. Not every courier accepts every perishable category, and size limits are tight.

Routing matters as much as service level. A direct flight removes the riskiest point in the journey, which is the transit airport where cargo is unloaded, stored and reloaded. If no direct flight exists, compare transit hubs by what cold storage they offer and how long the planned connection is. Also look at the day of the week. A shipment that lands just before a weekend or public holiday may sit until inspectors and brokers are back at work. Ask your forwarder to propose a flight schedule built around your consignee's receiving hours, not just the earliest available departure.

Packaging and temperature control that survive the tarmac

Packaging is your only protection during the hours when nobody is actively cooling the cargo. In Thailand's climate, pallets waiting to be loaded can warm quickly, so design the pack for the worst stretch of the journey rather than the average.

The common building blocks are:

• **Insulated cartons or foam boxes** with a snug fit, so there is little empty air to warm up.
• **Gel packs** for chilled goods, conditioned to the right temperature before packing. Packs that are too cold can freeze-damage fresh produce.
• **Dry ice** for frozen goods. It is regulated as dangerous goods in air transport, so quantity limits, labelling and airline acceptance must be confirmed in advance.
• **Thermal pallet covers** to slow heat gain during ground handling.
• **Temperature data loggers** placed inside the load, so you have evidence of what happened if there is a claim.

Ask the supplier how the product is pre-cooled before packing. Warm product in a good box is still warm product, and no amount of gel will pull the heat out during transit. Also check the box against airline handling. Cartons should stack without crushing, absorb minor leaks and carry clear orientation and perishable labels.

Finally, run a trial. Before your first commercial order, send a small shipment with loggers over the same route. The readings will show where the temperature climbs, and you can then add insulation, change the coolant or switch flights with facts rather than guesses.

Documents and inspections on both sides

Paperwork delays hurt perishables more than any other cargo, because every hour in a queue is an hour off the shelf life. Split the work clearly between what Thailand requires for export and what your country requires for import.

On the Thai side, the exporter normally handles the export declaration and any product-specific certificates. Depending on the category, this can include a phytosanitary certificate for plants and fresh produce, a health certificate for animal or fishery products, and a certificate of origin if you plan to claim a tariff preference. Some products must come from registered packing houses or approved establishments to be eligible for certain markets. Requirements change, so ask the exporter which Thai authority issues each document and verify with public sources such as Thai Customs or the relevant ministry.

On your side, check with your own customs broker or food and plant health authority well before the first shipment:

• Do you need an import permit issued before the goods leave Thailand?
• Must the shipment be pre-notified to border inspection?
• Which labels, languages and date formats are required on the outer and inner packs?
• Are there limits on specific residues, additives or packaging materials such as wood?

Send draft documents to your broker for review before the flight departs. A typing error in a product name or a weight that does not match the air waybill is easy to fix while the cargo is still in Bangkok and painful to fix once it is sitting in a bonded warehouse.

Understand the cost and who carries the risk

Air freight for perishables is charged on chargeable weight, which is the greater of the actual weight and the volumetric weight. Insulated boxes and coolant are bulky, so your packaging choices directly change the freight bill. Ask the supplier for packed dimensions and gross weight per carton, then have your forwarder calculate chargeable weight before you agree on a price with anyone.

A realistic budget includes more than the airline rate:

• Packaging, coolant and data loggers.
• Chilled trucking from the packing house to the airport.
• Terminal handling, cool-room storage and screening fees at origin.
• Certificates and inspection fees.
• Destination handling, customs clearance, duties and taxes.
• Chilled delivery from the airport to your premises.

Rates move with season, fuel and available capacity, so treat any figure as valid only for the dates on the quote.

Incoterms decide who arranges and pays for each leg and where risk passes to you. Under FCA or FOB-style arrangements at Bangkok airport, you control the main carriage and your forwarder can manage the whole cool chain. Under CPT or CIP, the supplier books the flight, which is convenient but gives you less say over routing. Whatever you choose, ask about cargo insurance wording. Many standard policies exclude spoilage caused by delay or temperature deviation unless that cover is added, and insurers may ask for logger data to support a claim.

Pick partners and agree a handover plan

A perishable shipment passes through many hands: supplier, trucker, forwarder, ground handler, airline, broker and your own receiving team. It goes wrong where two of them assume the other is responsible. Your job as the buyer is to choose partners with relevant experience and make the handovers explicit.

When screening a freight forwarder, ask what perishable categories they handle regularly from Thailand, whether they have their own or contracted cold storage near the airport, and how they communicate when a flight is offloaded or delayed. A forwarder who has shipped your type of product before will already know which airlines accept it and how each terminal treats it.

When screening suppliers, look for export experience with air cargo to your region, not just domestic sales. You can find **Thai food and beverage suppliers** through trade fairs, the DITP exporter listings, B2B marketplaces such as **THAIMOST**, or referrals from your forwarder. Whichever route you use, do your own checks, request samples and confirm terms in writing.

Then put a simple timeline on one page and share it with everyone:

• Packing and pre-cooling time.
• Truck pickup and airport cut-off.
• Flight details and any transit point.
• Who clears customs at destination and when.
• Who collects, with which vehicle, and the receiving check for temperature and condition.

Agree in advance what happens if the flight is missed: return to cold storage, rebook, or cancel. Decisions made calmly beforehand are far better than decisions made at midnight by phone.
