Exporting Cut Flowers and Orchids by Air from Thailand

Thailand has long been a major source of orchids, with cut orchid sprays such as Dendrobium and Oncidium types, plus foliage and other cut flowers, moving by air to Japan, other Asian markets, the Middle East, Europe and Oceania. The trade rewards growers who treat the shipment as one connected system rather than a set of separate tasks. A flower is alive when it is cut, it keeps respiring in the box, and every hour between the farm and the florist's bucket comes out of its vase life. On top of that, plants and cut flowers are regulated as potential carriers of pests, so the paperwork is not a formality but the legal basis for entry. This guide walks through the whole chain as an exporter experiences it: who does what in Thailand, how the phytosanitary certificate works, when CITES matters and when it does not, how destination rules differ, what good packing and cold handling look like, how air space and cut-off times shape the schedule, and where shipments most often go wrong. It describes structure and typical practice. Specific limits, forms, fees and pest lists change, so the importer's current written conditions and the official source for each destination always come first. Information here reflects the position as of October 2026.

Why flowers are not like other air cargo

Most air freight tolerates a delay of a day with a cost, not a loss. Cut flowers do not. The product has a biological clock: it is harvested at a particular stage, cooled, hydrated and packed, and from then on every handover either preserves or spends its life. Three things work against it. Heat speeds respiration and ageing, so a box left on a warm apron or in an uncooled truck loses days of vase life in hours. Dehydration shortens life because a cut stem cannot refill itself if the water path is blocked or the stem dries. Ethylene, a gas given off by ripening fruit, damaged tissue and some packing materials, makes many flowers, including several orchids, drop buds or fade early. A cold chain that is broken once cannot be repaired later.

The second difference is regulatory. Plants are a pathway for pests that can damage the importing country's agriculture, so most destinations require evidence from the exporting country's plant-protection authority that the consignment was inspected and found free of quarantine pests, or treated if required. For cut flowers the practical concern is usually small insects such as thrips, mites, aphids and scale insects that hide in blooms and leaf axils, plus soil, snails or plant debris. A shipment that fails inspection at arrival can be treated, re-exported or destroyed at the importer's cost, and with a fresh product the delay alone can destroy the value.

The third difference is commercial. Flower buyers plan around fixed events and weekly auction or wholesale rhythms. A late arrival is not a small discount, it can mean the flowers miss the sales window entirely. These three pressures, biology, regulation and the calendar, are why exporters who succeed are usually the ones who decide the whole route backwards from the receiving market's schedule.

Who does what in Thailand

A cut-flower export involves five parties and the work divides cleanly. The grower or packhouse owns everything about the product: pest control in the field, harvest timing, grading, hydration, packing and the evidence that the consignment is clean. This party also decides what is being exported, which matters for CITES, because cut flowers and whole plants are treated differently. The Department of Agriculture is Thailand's plant-protection authority. Its plant quarantine officers inspect the consignment, sample it for pests, and issue the phytosanitary certificate. The same department acts as the management authority for plant species under CITES in Thailand, so it is also where permits for listed whole plants come from. Thai Customs handles the export declaration like any other cargo, and the airline or its handling agent accepts the freight and issues the air waybill.

The forwarder sits between these parties. A good perishables forwarder books space on flights that suit the destination's receiving hours, confirms the airline's cut-off and acceptance window, advises on the pallet or box build, coordinates inspection timing so the certificate is in hand at hand-over, and passes arrival information to the importer. The importer handles the destination side: any import permit, the booking of the plant-health inspection at arrival, customs clearance and onward distribution.

The common failure is not that one party does its job badly. It is that two parties assume the other one has dealt with something. Nobody confirms the certificate wording with the importer. Nobody checks that the inspection slot fits the airline cut-off. Nobody confirms who pays for a re-inspection. Naming one person to own each handover, in writing, removes most of these gaps.

The phytosanitary certificate and inspection

The phytosanitary certificate is the document that tells the importing country's plant-protection authority that the consignment was inspected by the exporting country's authority, was considered free from the quarantine pests of concern, and conforms to the importing country's current plant-health requirements. In Thailand it is issued by the Department of Agriculture after an inspection by plant quarantine officers. For air cargo, much of this work is done at or near the main airport, and the department has an electronic certification route, commonly referred to as E-Phyto, alongside paper practice, so the exporter should ask the officer or the forwarder which channel the destination accepts.

The process starts before the flowers reach the airport. The exporter normally needs to be registered with the department as an exporter of plants and plant products, and the farm or packhouse may have to meet requirements of its own, such as registration or a pest-management record, depending on the product and destination. The exporter applies for the certificate, giving the botanical name or accepted product description, the quantity, the packing, the consignee and the destination. An officer then inspects the consignment, usually by opening a sample of boxes and examining blooms, stems and leaves for live pests, symptoms, soil and debris. For orchids, thrips and mites are the usual concern. If the consignment passes, the certificate is issued. If it does not, the options are treatment, culling the affected units, re-packing or withdrawal, and each takes time the airline schedule may not allow.

Two practical points save a lot of trouble. First, the certificate must be consistent with the other documents. The consignee name, product description, quantity and any additional declaration should match the commercial invoice and the air waybill, because a mismatch can lead the destination inspector to question the whole consignment. Second, the inspection has to be scheduled inside the airline's acceptance window, not around it. Ask the forwarder to confirm the officer's availability and the airline's cut-off together, and build in margin so a re-inspection is not the difference between flying and missing the flight.

CITES: when orchids need permits and when they do not

Orchids are the single largest plant family covered by CITES, the international convention that controls trade in species threatened by exploitation. All orchids of the family Orchidaceae are listed in Appendix II, which means trade is allowed but controlled, and a few genera, notably the slipper orchids Paphiopedilum and Phragmipedium, are in Appendix I, where commercial trade in wild specimens is essentially prohibited. Thailand is a party to the convention and the Department of Agriculture is the management authority for plants, working through its permit system, including electronic permits, and under Thai plant-species legislation.

What catches many new exporters out is that the Appendix II listing for orchids comes with an annotation exempting certain forms of artificially propagated material. In plain terms, as commonly described, cut flowers of artificially propagated plants are exempt from CITES controls, as are seeds, spores and pollen, and flasked seedlings or tissue cultures that meet the stated conditions. That is why the typical commercial cut-orchid spray of a cultivated Dendrobium or Oncidium hybrid does not need a CITES permit even though it is an orchid. The exemption is about the form and the origin, not about the plant family.

Three cautions follow. First, whole plants are not covered by the cut-flower exemption. Potted orchids, bare-root plants and divisions of Appendix II species can need CITES documentation, and Appendix I material needs the strictest permits. Second, the annotation wording and the Appendices themselves are revised by the parties from time to time, so the exporter should check the current text on the CITES website and with the Department of Agriculture rather than rely on an old summary, including this one. Third, a destination country can have its own rules in addition to CITES, and some require documentation for items that CITES exempts. If there is any doubt about the species, the origin or the form, ask the management authority before you pack, not at the airport counter.

Destination plant-health rules

Each importing country writes its own plant-health rules, and they differ more than exporters expect. Some require only the phytosanitary certificate and a clean arrival inspection. Others add an additional declaration stating that a particular pest is absent from the area of production or that the consignment was inspected for it. Others require pre-clearance, registration of the exporter or packhouse, specified treatments, or a limit on the plant parts allowed. The Japanese market, an important destination for Thai orchids, is a useful example of the general pattern: a phytosanitary certificate from the exporting country's authority and a plant quarantine inspection on arrival, where the inspector examines the consignment and can order treatment or refusal. European Union and United Kingdom rules have, for orchids and other plants from Thailand, at times required a certificate with a declaration tied to a specific pest such as Thrips palmi, and the exact list of regulated organisms is updated from time to time. Middle Eastern and Oceanian importers publish their own conditions, and Australia and New Zealand apply some of the strictest biosecurity screening in the world to plant material.

For an exporter, the useful habit is to obtain the rule in writing from the importer, and verify it against the importing country's official plant-health website, before the first shipment to each new market and again whenever the market changes its rules. Ask four questions. Is a phytosanitary certificate required, and does it need an additional declaration? Is an import permit or pre-registration required on the importer's side? Are there limits on soil, packing material or plant parts, for instance on wood in the packaging? And what happens on arrival if a pest is found: treatment, destruction or return, and at whose cost? The answers shape the packing, the certificate and the contract, and getting them wrong shows up after the flowers are already in the air.

Packing and cold chain

Packing is where vase life is protected or lost. The sequence usually runs as follows. Harvest at the stage the buyer specifies, which for orchid sprays is typically when a set number of florets on the stem are open, so the remaining buds open at destination. Move cut stems out of the field heat quickly into shade and then into a cooler, because pre-cooling removes field heat before the flowers enter the box. Keep stems hydrated. Orchid sprays are often shipped with the cut end in a small water tube, a water-holding gel or a wet wrap, and the method should be the one the buyer and the grower have agreed, because some markets object to free water in the box and others expect it.

Protect the blooms physically. Orchid florets bruise at a touch, so sprays are usually separated with tissue or foam, laid so they cannot slide, and held in rigid corrugated boxes with vent holes sized for cooling air. Boxes should not be over-filled, because a crushed bloom looks damaged on arrival even if the flower is healthy. Avoid packing materials that carry soil or plant debris, and check the packing rules of the destination, since wood in packaging can be regulated. Keep flowers away from ethylene sources, including ripening fruit and fresh-cut foliage that has been stressed, and in some cases an ethylene inhibitor treatment is used if the buyer asks for it.

Finally label the box. A clear orientation arrow, the words for perishable goods, the consignee, the product and the handling temperature help the airline and the destination handler treat the box correctly. Hold the packed boxes at the grower's specified temperature, often a cool range well above freezing for tropical flowers, because orchids from the tropics can suffer chilling injury if they are kept too cold. Cold is a tool, not a goal: the target is the temperature the product tolerates, and the point is to keep it steady until the airline accepts the cargo.

Booking space, cut-offs and airport handling

Air space for perishables is booked, not assumed. Flower exporters usually work through a forwarder who holds regular allocations on routes to the main destinations, and the booking sets the date and the flight. The key time is the airline's cut-off, the latest moment at which the cargo, with documents complete, must be accepted at the terminal for the chosen flight. Acceptance windows differ by airline, route and terminal, and they are generally tighter for perishables, so the forwarder's confirmation of the cut-off for that specific flight should be the working deadline, not a rule of thumb.

In Thailand, most cut-flower exports leave through the main international airport, where there are perishable handling facilities with cold rooms operated by the cargo handlers. Cargo is normally delivered to the airline's or handler's terminal, weighed and checked against the air waybill, screened for security, and then either built onto a pallet or container or kept in a cold room until build-up. A box left standing in an unconditioned area while waiting for screening or build-up is the commonest way the cold chain breaks at the airport, so the exporter should ask the forwarder how the terminal handles the cold-room step and what the dwell time normally is.

Three choices affect cost and risk. Direct flights shorten transit but may have fewer weekly departures, while connecting routings add a transfer where the cold chain can break. Charging is by chargeable weight, which compares actual weight with volume, and flowers are bulky, so box dimensions and packing density directly affect the freight bill. And capacity is seasonal: demand for flower space rises ahead of major holidays, so booking early in those periods is not optional. Ask the forwarder for the routing and the transfer points, because a shipment that looks cheaper on paper can be the one that spends hours on a warm ramp at a transit airport.

From packhouse to aircraft: the order of events

The sequence matters because several steps depend on each other and the clock is running throughout. Work backwards from the flight. The importer first confirms the destination's current written conditions and, where needed, the permit or registration on its side. The exporter then books the space and confirms the cut-off in writing with the forwarder. The grower plans harvest and packing so the flowers are cut as late as sensible and cooled and packed without delay. In parallel, the exporter applies for the phytosanitary certificate and fixes the inspection time at the airport or the inspection point agreed with the department.

On the day, the packed and pre-cooled boxes travel to the airport in a temperature-controlled vehicle. The consignment is presented for inspection with the application, and once it passes the certificate is issued. The cargo is then delivered to the airline terminal within the acceptance window with the invoice, packing list, certificate and any other documents, and the export declaration is processed. After the terminal accepts the freight and issues the air waybill, it is built onto the flight. The forwarder sends the importer the flight details, the air waybill number and copies of the documents, ideally before departure, so that the importer can book the arrival inspection and the pickup.

What makes this work is margin. If the certificate is issued only minutes before the cut-off, any delay in the inspection means a missed flight. Experienced exporters schedule inspection early in the day, keep a buffer before the cut-off, and agree in advance what happens if a consignment fails inspection: which units can be culled, whether treatment is possible in time, and whether the booking can move to the next flight. Deciding that in advance is far cheaper than deciding it in the terminal car park.

What goes wrong and why

Most problems with orchid and cut-flower exports fall into a few repeating patterns. The first is live pests found at inspection. Thrips are small, hide in blooms and are easy to miss, so an exporter without field pest management and a disciplined cleaning step at the packhouse is relying on luck. Prevention starts in the field, with monitoring and control, and continues with grading out damaged or infested stems before packing. The second is a document mismatch: a certificate that names a different consignee, quantity or product description than the invoice, or that lacks the additional declaration the importer needed. The third is the broken cold chain, usually a short hold on a warm surface at the farm gate, the airport or a transit point, which only shows up at destination as early fading or dropped buds.

The fourth pattern is the CITES surprise. An exporter ships a few potted plants or a divided clump alongside the cut sprays, or sends a species that turns out to be in Appendix I, and the consignment is held because the permit was never obtained. The fifth is the schedule collision, where inspection, cut-off and flight times are each reasonable on their own but do not fit together, so one slip cascades. The sixth is the commercial dispute: flowers that arrive with reduced vase life and a buyer who claims a quality defect. Photographs at packing, temperature records where available, and a clear agreement on grading and acceptance standards make that dispute much easier to resolve.

None of these problems is exotic. They are the same few failure modes repeated by different exporters. The lowest-cost protection is a pre-shipment checklist owned by one person, which covers the destination rules, the species and form, the pest-control record, the document consistency, the packing spec, the booking and cut-off, and the plan if something fails.

Three common structures

Three typical set-ups show how the same principles apply differently. The first is a cut-orchid spray exporter shipping weekly to an Asian wholesale market. The product is cultivated Dendrobium, so no CITES permit is needed for the cut flowers, the focus is the phytosanitary certificate, thrips control, a steady cold chain and a forwarder with a reliable weekly allocation. Repeat shipments make the process routine, which is exactly when complacency about certificate wording and cut-offs causes the occasional costly miss.

The second is an exporter adding a European destination. The rule set is new: certificate requirements, possible additional declarations tied to specific pests, import-side registration and a longer transit with a connection. The right move is to ask the importer for the written conditions, verify them against the official plant-health source, start with a small trial consignment, and agree what happens on a failed inspection before the first full load. The extra transit time makes packing and temperature discipline matter more, not less.

The third is an exporter who also wants to ship potted orchids or plant divisions alongside the cut flowers. This is the structure that triggers CITES. Whole plants of Appendix II orchids can require permits, the botanical names and origin must be documented, and the Appendix I slipper orchids are a separate and far stricter matter. Here the exporter should speak to the Department of Agriculture before quoting a price, and treat the plant side as a distinct export with its own lead time, rather than adding it as an afterthought to the cut-flower booking.

Working with a forwarder and sequencing the work

A forwarder cannot grow better flowers, but it can protect them from the moment they reach the pallet. The most useful ones for flowers are those who handle perishables regularly: they know which routings and terminals handle cold cargo well, hold weekly space, and can tell you honestly when a booking is unrealistic. Brief the forwarder with the destination, the product and form, the box count and dimensions, the temperature requirement, the required certificate wording, the cut-off you need to hit and who is responsible for each handover. Ask for the routing, the transfer points and the contingency if the flight is cancelled.

Sequence the work in this order. First confirm the destination rules in writing and check CITES if any whole plants are involved. Second fix the product specification, the grading standard and the packing method with the buyer. Third book the space and confirm the cut-off. Fourth line up the inspection and the certificate. Fifth harvest, cool and pack against the schedule. Sixth deliver, document and fly, and send the importer the arrival information. After each shipment, record what worked and what slipped, because the second consignment to a market goes much better than the first when the lessons are captured.
