Exporting Durian and Fresh Fruit from Thailand to China: Modes, Registration, Cold Chain and Border Risk

Few export cargoes are as unforgiving as fresh fruit, and few markets matter as much to Thai fruit growers as China. Durian is the headline example, but the same logic applies to other fresh tropical fruit headed north: the product is perishable, the buyer expects specific quality at arrival, and every hour in the chain eats into the time the fruit has left. This article explains how a fresh-fruit shipment to China is structured, why speed and temperature dominate every decision, the three main transport modes, the registration and certification concepts that sit behind market access, how the cold chain should work, why border inspection is the main source of delay and rejection, and how to coordinate with the buyer. It deliberately gives no volumes, prices or transit days, because those vary by season, route and carrier. Treat it as a framework and verify every current requirement with the relevant agencies and your buyer.

Why speed and temperature dominate every decision

Fresh fruit is alive. After harvest it keeps respiring, ripening and ageing, and the rate of that change is driven largely by temperature. Warm fruit ripens and deteriorates faster; fruit held at its proper carriage temperature slows down. Durian adds its own difficulties: it is typically harvested at a maturity chosen so that it can travel yet still reach the buyer in sellable condition, and fruit cut too early can fail to ripen properly while fruit cut too late can arrive overripe. The right maturity is something the buyer's specification and your own experience will define, and this article cannot state it.

What this means for logistics is that time and temperature are not just cost items, they are the product's quality. A day lost at a border is not neutral, it is shelf life spent. A refrigeration unit that fails for a few hours may not leave visible damage at the time, yet show up as soft, fermented or split fruit on arrival. The practical consequence is that every choice in the chain, which packing house, which truck or container, which mode, which clearance route, should be judged by how it protects the remaining shelf life, not only by its price.

It also explains why buyers in China tend to be exacting about quality at arrival, and why disputes about condition are common in this trade. The exporter's best protection is a documented, unbroken process: harvest records, pre-cooling records, temperature logs and clean paperwork. These do not ensure acceptance, but they let you show what happened if the buyer disputes the condition of the cargo.

Three ways to move fresh fruit to China

Three modes are used for fresh fruit, and none is universally best. Which one fits depends on the fruit, the shelf life that fruit has, the volume, the budget and the buyer's preference.

Road freight is attractive for fresh produce because trucks can load at or near the packing house and run overland towards China without a port transfer. Routes often pass through Laos, and for the broader road corridor and how cross-border trucking works from Thailand, the guide on R3A road freight between China and Thailand via Laos explains the corridor and what to expect from it. The strengths of road are flexibility and a relatively direct path; the weaknesses are the number of border crossings, the reliability of the refrigeration unit over a long haul, driver and vehicle readiness for each border, and the queueing risk at crossings. Plan for a reefer trailer with a proper unit, a pre-trip check, and a temperature logger.

Sea freight in a refrigerated container, a reefer, carries large quantities at a stable controlled temperature, which makes it suitable when volume is high and the fruit's shelf life tolerates the longer time on the water. The extra time means that quality at the packing house and discipline at the port matter more, since there is less margin if anything goes wrong. For how sea and air compare for fresh fruit in general, see the article on exporting fresh fruit by sea versus air freight, and for the container itself, the types of reefer containers.

Air freight has the shortest time in transit and is used where shelf life is the limiting factor or where the fruit's value supports the freight cost. Capacity per flight is limited, handling at airport cargo terminals adds its own steps, and the packing has to suit air carriage. The decision is rarely about speed alone: it is about whether the extra shelf life arriving at the buyer's end justifies the extra cost and constraints.

Many exporters use more than one mode through a season, depending on the fruit and the buyer. A forwarder can help you compare options for a specific lot, but the choice should always start from the fruit's remaining shelf life at the point of sale.

Orchard and packing-house registration: the market-access concept

Selling fresh fruit into China is not simply a matter of finding a buyer and a truck. Importing countries commonly require that the fruit come from sources that the exporting country's plant-health authority has registered and that the importing side's authorities recognise. In practice this has usually meant that orchards growing for the export market and packing houses that sort and pack the fruit are registered, with their registration details linked to the cartons, the certificate and the export documents so that a consignment can be traced back to its source.

The details of that system, who must register, what standards a facility must meet, how long registration lasts, and what happens when a facility is suspended, are set by the authorities on each side and have changed over time. In Thailand, the agency that typically handles plant-health matters for exports is the Department of Agriculture, and the practical advice is to confirm with it, and with your Chinese buyer, what is currently required for the specific fruit you want to ship. Do not assume that a registration that worked for one fruit, one season or one buyer automatically covers another.

The operational point to take from this is that registration is part of your logistics, not a separate admin task. If the carton markings, the packing-house identity and the certificate do not agree, the cargo can be delayed or refused at the border no matter how perfect the fruit is. If you buy fruit from other growers rather than growing it yourself, make sure the supply chain from those orchards to a registered packing house is documented, and do not mix registered and unregistered fruit in the same lot. Ask your buyer early what traceability information they expect on the carton and in the paperwork.

Phytosanitary certification and the paperwork that travels with the fruit

A phytosanitary certificate is the plant-health authority's statement that a consignment has been inspected and meets the importing country's plant-health requirements as understood by the issuing authority. For a plain-language explanation of what the certificate contains and what it is for, see what a phytosanitary certificate is. For fresh fruit going to China, it is one of the central documents, and it travels with the cargo alongside the commercial invoice, packing list, transport document and the export customs declaration.

What matters for logistics is consistency and timing. The certificate describes the consignment: the product, the quantity, the packing-house or origin identity, the destination and the consignee. Those details must match the invoice, the packing list and the carton markings, because the destination's inspectors will compare them. A certificate issued after the truck has left, or one that does not arrive with the original on time, can hold up clearance at exactly the moment the fruit can least afford to wait.

Build the document timeline backwards from the departure time. Agree when inspection and certification will happen at the packing house or the inspection point, who will collect the original, and how copies will be sent ahead to the buyer and the customs broker. Confirm which documents the buyer and the destination customs broker need as originals, which as copies, and in what form. For a general view of the export documents that accompany any shipment, see the export documents checklist.

Because rules and forms for fruit move with the importing side's requirements, this article does not name specific forms or permit numbers. Ask the Department of Agriculture, your buyer and your forwarder or customs broker for the current list for your fruit and route, and keep a written record of what you were told and when.

Cold chain, pre-cooling and pallet packing

The cold chain for fresh fruit is a chain of handovers, and it is only as strong as its weakest link. The general principles are set out in the article on cold chain for food exports; here the focus is on what matters for fruit going to China.

Pre-cooling comes first. A refrigeration unit in a truck or container is designed to hold a temperature, not to pull a warm load down quickly. Fruit that goes into the unit warm brings its own heat with it, and the unit may never catch up. Pre-cooling at the packing house, bringing the fruit down to its carriage temperature before loading, is therefore one of the most valuable steps in the chain. The right target temperature and handling for each fruit depends on the fruit and the buyer's instructions, so confirm it rather than copying a number from elsewhere.

Packing and palletising come next. Cartons must be strong and ventilated as the fruit requires, stacked in a pattern that lets cold air circulate rather than blocking it, and secured so they cannot shift or crush the fruit below. Durian in particular has a strong smell and a spiky husk, which affects how it is packed and how adjacent cargo is chosen. Pallets should be built to the dimensions of the truck or container, labelled clearly, and loaded so that the airflow path of the refrigeration unit is not obstructed. The article on what a pallet is in freight shipping explains the basics.

Finally, monitor and record. A temperature logger in the load, set-point checks before loading, and a documented record of the loading temperature give you evidence of what happened if the buyer later disputes the condition of the fruit. Insurance is worth thinking about too: an exporter can ask an insurer and forwarder what refrigerated-cargo cover exists and what conditions, such as proof of correct temperature, it requires, as covered in the guide to what cargo insurance is.

Border inspection: why cargo gets delayed or rejected

For fresh fruit, the border is where the clock and the paperwork collide. The destination's authorities check that the documents are in order and that the cargo matches them, and they may inspect or sample the fruit. How thorough the checks are, and how long they take, depends on the destination's rules at the time, the inspection load at that crossing or port, and how clean your consignment looks on paper. Those are not things an exporter controls, which is why the controllable parts need to be right.

Common reasons a load is delayed or held include a mismatch between the certificate, the invoice and the carton markings; a registration that has lapsed or does not cover the fruit or facility named; missing original documents; incomplete or inconsistent declarations; and queues at the crossing itself. Reasons a load may be rejected or have problems at arrival include evidence that the temperature was not maintained, fruit that is overripe or damaged on opening, and any finding that the destination's authorities treat as non-compliant with its requirements.

The commercial effect is severe because delay for fruit is not neutral. Time spent waiting may push the fruit past its sellable window, and a rejected load has very little salvage value. For that reason, plan the border stage as carefully as the journey. Know which crossing or port the load will use and what the buyer's customs broker expects. Make sure the originals and copies reach the right people before the truck or vessel does. Keep a contact person reachable at the right time. Ask the buyer how they handle a held load, who decides what to do, and who pays, and agree this in writing, since fruit cannot wait while parties argue.

If cargo is held for reasons outside your control, such as a surge in inspection queues, speak with the forwarder and buyer immediately about options, and document the temperature and condition. The article on what to do when cargo is held by customs explains the general steps on the Thai side, and the same discipline of acting fast and documenting everything applies at the destination.

Buyer coordination: the part that decides whether the shipment works

With perishable cargo, the commercial relationship is part of the logistics. A fruit shipment lands well when the buyer is ready for it and badly when it is not, even if the fruit itself is perfect. Coordination should cover several concrete points.

Start with specifications and acceptance. Agree in advance the fruit's maturity, grade, packing format, carton marking and any temperature requirement, and agree how condition will be assessed on arrival and by whom. The more precisely this is written down, the less room there is for a disagreement after the fact.

Then agree the arrival plan. Tell the buyer which mode and route you are using, when the vehicle or vessel departs, and when you expect arrival, as an estimate that can change. Confirm who clears the cargo at the destination, who holds the originals, who arranges unloading and onward delivery, and who is available out of hours, since a truck arriving in the evening still needs someone to receive it. Decide in advance what happens if the shipment is delayed or held.

Then agree the money and risk. The sales terms, the Incoterm, decide who is responsible at each stage, and for perishable cargo it is wise to be explicit about who bears the risk of delay and condition. The article on choosing Incoterms for SMEs is a useful starting point. The payment method also matters: for a first shipment to a new buyer, consider how to protect yourself against non-payment, and the article on export financing and credit insurance describes the tools available.

Finally, keep communication tight during transit. Share the temperature log or tracking status if the buyer wants it, flag issues early, and keep a single person on each side responsible. A forwarder such as TGF can coordinate booking, documents and the customs handoff, and can help you line up a quote across the modes. When you are ready to plan a specific fruit shipment, request a quote with the fruit, packing, volume, and timing and we can talk through the options. Verify every current requirement with the authorities and your buyer before the first load leaves.
