Thailand Cannabis GACP is a standard concerning good agricultural and collection practices for cannabis. A certificate should identify the operation and scope it covers. It is not a product's prescription, a guarantee of treatment benefit or proof that every activity of a company is authorised.
The earlier version of this page reproduced an unofficial English translation alongside an expired webinar invitation. This revision provides a reading guide to the official material. It does not reproduce or amend the standard itself.
Start with the official documents
DTAM publishes application material, requirements and links for the Thailand Cannabis GACP assessment process. Use the current documents on the agency site and check their individual version dates. The date on a website upload path is not necessarily the date the standard or notice took effect. DTAM GACP assessment information and documents.
The same page warns about an unauthorised third-party service. This is a practical reason to verify the issuer and application route through an independently obtained official contact. A site name containing “GACP” does not establish government affiliation.
What should a certificate tell you?
| Field | Question |
|---|---|
| Holder | Which legal person or operator is named? |
| Site | Which premises or cultivation source is covered? |
| Scope | Which standard and activities were assessed? |
| Issuer | Who issued the document, and how can it be checked? |
| Validity | What dates, conditions or limitations apply? |
| Link to supply | How does this document connect to the harvest being supplied? |
Keep the full document, not only the page carrying a logo. If the brand, operating company and source have different names, ask for the evidence connecting them. A certificate for a related company or another site may not cover the delivery under consideration.
GACP, manufacturing and testing answer different questions
Agricultural and collection standards concern the source operation. Manufacturing standards concern the activities and premises within their scope. A laboratory report concerns a specific sample and the tests performed. Do not call these documents interchangeable or infer that GACP alone is the same as pharmaceutical manufacturing approval.
For a buyer, these records can complement one another. The task is to identify which is required for the actual activity and product. A report needs a sample or batch identifier, dates, methods or analytes and results; a certification needs its own issuer, scope and validity.
Is Thai GACP the only accepted source route?
No. The DTAM sourcing notice dated 1 September 2025 and published on 12 September 2025 sets out Thailand Cannabis GACP and additional routes with their own conditions, including harvest-specific testing where stated. Do not reduce the notice to a slogan that only one certification label can qualify. Official sourcing notice and annex.
Our accepted sourcing routes guide explains the clauses. Resolve which route applies before relying on a supplier's documents. A test result for one harvest is not open-ended certification of every future harvest.
Connect the source to the stock record
Suppose a delivery arrives with a certificate naming the source but no record connecting it to the batch. The source document may be relevant, but the supply trail remains incomplete. Ask for the missing relationship, keep the receiving record and record the resolution before treating the paperwork as complete.
For a practical record flow, read the traceability guide. For the official forms associated with different activities, use our PT records guide. Software can organise those records; it cannot make an unrelated certificate apply to a batch.
Reading translations responsibly
An unofficial translation can help a reader navigate a Thai document, but it should state who translated it, the source edition and its limits. Where wording affects a business decision, check the Thai original with the relevant authority or adviser. Do not treat a shortened blog translation as the operative document.
The previous “GAPC” spelling and “webinar tomorrow” invitation have been removed. They referred to older material and did not describe a current event or a new legal deadline.
Updated 6 September 2026. This page is an editorial guide to the linked official documents, not an official translation or certification service.
