Exporting GACP Cannabis Flower from Thailand: How the Process Actually Works

Why Thai origin is worth considering at all

Thailand legalised medical cannabis in 2018 and remains the only country in Southeast Asia with a functioning legal export framework for cannabis flower. The economics are structural, not temporary: year-round tropical climate, purpose-built indoor facilities, and labour and energy costs well below European or Canadian levels.

The regulatory filter is real. As of late 2025, more than 11,800 cultivation licences have been issued in Thailand — but only 149 farms hold GACP certification. Fewer still hold both the Thai DTAM Cannabis GACP and a European certification such as Control Union's WHO/EMA GAP & GACP declaration. That narrow overlap is the pool an importer actually chooses from.

The two certifications that matter

Thai regulation and European buyers use different rulebooks, and a serious exporter holds both.

Thailand DTAM Cannabis GACP (Department of Thai Traditional and Alternative Medicine, Ministry of Public Health) certifies the cultivation site itself. Our Sabai Sabai Farm site in Chanthaburi province holds certificate TH-GACP 87/2568, covering a 4,104 m² indoor facility and valid until September 2028. It is issued in the "Complete Edition" — the full standard, not the transitional reduced scope.

Control Union GAP & GACP Declaration (the WHO guideline and the EMA guideline on Good Agricultural and Collection Practice for herbal starting materials, EMA/HMPC/246816/2005 Rev. 1) is what European and Australian partners typically ask for first; in the trade it is usually referred to as EU-GACP. Our Sabai Sabai Farm site holds this declaration, valid until September 2027. It covers propagation through cloning, cultivation, harvesting, drying, curing, packaging and storage of Cannabis sativa inflorescences for medicinal use.

What a batch file contains

A complete export batch file — the set a European or Australian buyer's quality team works from — typically contains:

• Certificate of Analysis from an independent laboratory: full cannabinoid profile (THC, CBD and minors), terpene profile, heavy metals (arsenic, cadmium, mercury, lead), aflatoxins B1/B2/G1/G2, pesticide panel, microbiology, foreign matter and moisture content;
• batch and lot numbers traceable to the specific harvest and room;
• cultivation record: strain, room, harvest date, drying and curing parameters;
• packaging specification and net weights.

Our flower is dried whole-plant and hand-processed; drying ends when in-flower moisture sensors read 11%. Curing runs from two weeks, adjusted per cultivar. We operate 15 flowering rooms of roughly 70 kg each — an installed capacity of about 900 kg per month, dropping cultivars in rotation roughly every 10 days.

Australian imports: TGO 93 in practice

Australia regulates imported medicinal cannabis under Therapeutic Goods Order No. 93 (Standard for Medicinal Cannabis). For flower, the practical hurdles are microbial limits, absence of unapproved pesticides, and heavy-metal thresholds.

Since the GMP requirements in TGO 93 took effect in 2023, imported finished products must come from a GMP-compliant site. Flower from a GACP site such as ours enters Australia as starting material for an Australian TGA-licensed manufacturer, which performs the GMP steps. Our samples have been tested against TGO 93 parameters in Australia. Two practical notes:

1. Irradiation. Many Australian importers irradiate imported flower to meet microbial specifications. Who pays for irradiation, and whether the contract requires it, should be settled in the supply agreement — not discovered at customs.
2. Testing jurisdiction. Testing happens in the importer's country, in laboratories the exporter does not control. A workable contract names a jointly agreed list of ISO/IEC 17025-accredited laboratories, uses split samples so the producer retains a counter-sample, and provides for referee testing when results are disputed.

EU imports: what German and Spanish buyers ask first

For the EU the sequence is different: the first questions are GACP status of the site, then batch COAs to Ph. Eur. methods, then the importer's own GMP release. Cannabis flower enters the EU as an active substance; the EU-GMP release step sits with the importer's qualified person, which is why a Thai producer's GACP + full batch documentation is the entry ticket, not EU-GMP of its own.

Non-irradiated flower is a differentiator in the German market — several distributors explicitly source it, and few origins can supply it consistently.

The commercial structure that actually works

The pattern we see across working Thai export deals is a local purchase: the importer (or its agent) buys the product in Thailand, takes title before the export procedure, and manages importation in its own jurisdiction. Payment is settled in full before export formalities begin. This allocates each risk to the party that controls it: the producer stands behind the product — replacement or credit note for a confirmed non-conforming batch — while importation, in-market testing and distribution economics belong to the importer's side of the table.

Variations exist (deposit/balance structures tied to test confirmation, for example), but every variation is a negotiation about the same three questions: who tests, who pays for testing, and what happens when a result is disputed.

Documents an importer should expect from a Thai exporter

• Thai DTAM GACP certificate for the cultivation site (with number and validity dates);
• European GACP declaration (Control Union or equivalent);
• batch COA from an independent laboratory, with the method base stated;
• Thai export permission for the specific shipment (issued per-shipment by the Thai FDA);
• import permit on the buyer's side — Thailand issues export permission against it;
• packing list, invoice, and phytosanitary documentation as required by the destination.

If an exporter cannot show the first three before contract discussions begin, that is the signal to stop early.

What importers ask, in the order they ask it

Across our correspondence with buyers in Germany, Spain and Australia the same questions arrive in almost the same sequence. If you are evaluating a Thai supplier, this is a reasonable checklist to work through:

1. Current product list, availability and indicative pricing.
2. EU-GACP and Thai GACP certificates — including their exact scope and validity dates.
3. Current GMP status for processing and batch release, and where that step happens.
4. Product specifications and sample certificates of analysis.
5. Stability data, irradiation status, packaging format and minimum order quantity.
6. European or other markets previously supplied, and the regulatory route used.

A supplier who answers the first four from a folder rather than from memory has done this before. A supplier who needs a week to locate a certificate has not.

Minimum order quantity and order economics

We do not set a fixed minimum order quantity. The real constraint is not our production floor but the economics of export: permits, testing, freight and customs handling cost roughly the same for a small consignment as for a large one, so below a certain volume the per-kilogram landed cost stops making sense for the buyer.

In practice this means the first shipment is usually sized to prove the route rather than to fill a warehouse — enough material to run the importer's own release testing and reach the market, with the commercial volume following once the documentation path is known to work.

Which markets Thai flower has already reached

Flower from our sites has been imported by clients into Germany, Portugal and Switzerland. Our samples have been tested against TGO 93 parameters in Australia.

This matters for a first-time importer for a specific reason: the regulatory path from Thailand to those markets has been walked, and the documentation set that satisfied those customs and health authorities exists. A producer shipping to a market for the first time is learning the paperwork at your expense.

How Thailand compares with other origins

Buyers rarely compare Thai producers only with each other. The realistic comparison set is Portugal, Colombia, South Africa, Morocco and EU-GMP material from Canada.

Portugal is the largest exporter in Europe and second largest in the world after Canada: exports rose 172% in 2024 to 32,558 kg, and of 61 companies holding INFARMED medicinal cannabis licences, 25 hold EU-GMP certification. Portuguese material arrives inside the EU with the GMP step already done, which shortens the importer's path — and is priced accordingly.

Thailand competes on a different axis: cost structure and cultivation conditions. Year-round tropical climate, purpose-built indoor facilities, and labour and energy costs well below European or Canadian levels. The trade-off is explicit — the GMP release step stays with the importer.

Neither origin is universally better. The question is whether your operation already has, or wants, the release step in-house.

Genetics, phenohunting and why cultivar consistency is hard

We select cultivars in-house from seed rather than buying finished genetics. A phenohunt runs a population, evaluates individual plants for terpene profile, structure, yield and resistance, and keeps the mother that performs — which is then cloned for production.

The reason this matters commercially is repeatability. A buyer who sells a cultivar to patients or to a brand needs the next batch to smell and test like the last one. Seed-grown production drifts; clone-grown production from a selected mother does not, provided the room conditions are held.

We run 15 flowering rooms of roughly 70 kg each and drop cultivars in rotation approximately every 10 days. That rotation is what allows a steady supply of several cultivars rather than one large harvest followed by months of nothing.

Hand-trimming, drying and curing

Machine trimming is faster and cheaper, and it knocks trichomes off the flower. We trim by hand, which preserves the resin layer that carries both cannabinoids and terpenes.

Drying is whole-plant and ends when in-flower moisture sensors read 11%. Curing runs from two weeks and is adjusted per cultivar. These numbers are not marketing: under-dried flower fails microbiology, over-dried flower loses terpenes and crumbles in transit, and both failures show up in the importer's release testing rather than in ours.

Irradiation: why we do not

Irradiation is the standard fix for microbial counts, and in several markets it is routine. We do not irradiate, because irradiation measurably reduces terpene content.

For a buyer this is a decision point rather than a feature. If your market or your customer requires irradiated material, that requirement should be written into the supply agreement together with who performs it and who pays. Discovering the requirement after the goods have landed is the expensive version of this conversation.

What actually goes wrong on a first shipment

From what we have seen, first-shipment problems are rarely about the flower.

Documentation mismatch. The name of the exporting entity on the invoice does not match the entity on the GACP certificate, or the batch number on the COA does not match the batch on the packing list. Customs treats this as a discrepancy, and the goods wait.

Testing jurisdiction left undefined. Testing happens in the importer's country, in laboratories the exporter does not control. Without an agreed laboratory list, split samples and a referee procedure, a single out-of-specification result becomes a commercial dispute with no mechanism to resolve it.

Irradiation assumed rather than agreed. See above.

Permit sequencing. Thailand issues export permission against the buyer's import permit. If the import permit is delayed, nothing on the Thai side can proceed — and this is frequently discovered late.

Working timeline

The sequence is fixed even when the durations vary:

1. Technical evaluation — certificates, specifications, sample COAs.
2. Samples, where the destination regulation permits their import.
3. Commercial agreement, including testing and non-conformity terms.
4. Buyer obtains the import permit in its own jurisdiction.
5. Thai export permission is issued per shipment against that import permit.
6. Batch documentation, packing, freight.
7. Arrival, importer's own release testing, market entry.

Steps 4 and 5 are the ones that set the calendar, and neither is under the producer's control. Any supplier who promises a fixed delivery date before step 4 is complete is describing a hope, not a plan.

GACP, GAP and EU-GMP: what each one actually covers

These three acronyms are used interchangeably in sales material and mean quite different things.

GAP — Good Agricultural Practice. The agricultural baseline: soil, water, inputs, worker hygiene, record-keeping. It applies to crops generally, not to medicines.

GACP — Good Agricultural and Collection Practice. The pharmaceutical-facing standard for herbal starting materials, set out in WHO and EMA guidelines. It covers propagation, cultivation, harvest, drying, curing, packaging and storage, and it requires traceability from the plant to the packed batch. GACP is what certifies a cultivation site. It is the standard a Thai producer can and should hold.

EU-GMP — Good Manufacturing Practice. The standard for manufacturing a medicinal product, including batch release by a qualified person. Cannabis flower enters the EU as an active substance; the GMP release step is performed inside the EU by the importer or a contracted manufacturer.

The practical consequence is often missed in contract drafting: a GACP producer supplying unfinished product cannot be held to GMP obligations for that product. If a supply agreement treats delivery of non-GMP-compliant material as an immediate breach, it is describing an impossibility for any GACP-only origin — Thailand, Colombia or otherwise. That clause needs a written carve-out for unfinished product, and it is worth catching before signature rather than after the first delivery.

Packaging, storage and transit

Flower is packed to protect two things that degrade fastest: moisture content and terpenes.

Our standard export packing is vacuum-sealed food-grade bags inside sealed cartons, with batch and lot identification on both the inner and outer packaging so that a customs inspection does not require opening the primary pack. Net weights are stated per unit and per carton on the packing list.

Storage before shipment is in a controlled room; the practical enemies are heat and light rather than time. In transit, a sealed container in the hold is stable enough for the journey — problems arise from delays at customs, not from the flight itself, which is another reason permit sequencing matters more than freight choice.

Buyers who intend to repack for their own market should say so early: repacking under a different brand has its own requirements in most jurisdictions, and the batch identification chain has to survive it.

Requesting samples

Samples are the point where regulation, not willingness, sets the pace. In most destination markets a sample of cannabis flower is legally the same thing as a commercial import: it requires the buyer's import permit before Thailand can issue export permission.

This is why "send us a few grams" is rarely a small request. What usually works instead:

• full batch documentation and COAs first, which answers most technical questions on paper;
• laboratory data reviewed by the buyer's own quality team;
• samples arranged once an import route exists, or drawn from material already landed in the buyer's jurisdiction.

Where a buyer already holds a permit, sampling is straightforward and we arrange it against that permit.

Price: what actually moves it

We do not publish price lists, because a number without a specification is meaningless. What moves the price is knowable in advance:

• cultivar and phenotype — rare genetics and high-terpene selections cost more to produce and yield less;
• cultivation type — indoor material carries a different cost base than greenhouse;
• grade and preparation — hand-trimmed premium flower against material destined for extraction;
• volume and continuity — a recurring monthly offtake prices differently from a single consignment;
• who carries which cost — testing, irradiation if required, freight and permits all sit somewhere in the number.

A quotation from us names the cultivar, the grade, the batch documentation that comes with it and the delivery basis. A quotation that names only a price per gram is not comparable with anything.
