Buying a GACP farm: what to check before you sign
Thailand Cannabis Report · Reefers Club Co., Ltd. · Last checked 31 October 2026
A certified farm is one of the few assets in Thai cannabis that the 2025 rules made more valuable: licensed shops must buy from certified sources. Buying one is also full of traps, from land ownership to whether the farm's output can lawfully be sold.
Ownership and land
- Cultivation is an agricultural business restricted for foreign-majority companies under the Foreign Business Act. Verified
- Foreigners face restrictions on owning land in Thailand. Check how the land is held: owned, leased or used under another right.
- Nominee arrangements are an offence for both parties under section 36. See the nominee trap.
Certification and records
- A current DTAM GACP certificate in the farm's name. See GACP certification.
- If there is no GACP, a record of laboratory certificates for each harvest. See lab testing per harvest.
- Cultivation records: inputs, harvests, drying and storage.
- Any licences the farm holds for selling or processing.
Buyers and channels
- Who buys the flower now, and are they licensed?
- Do sales records match harvest records?
- Is any output going into extracts, which need their own licence and are closed to foreign businesses since 25 April 2026? Verified
- Is anything exported? Export needs its own licence and notification, and Customs raised the smuggling fine in June 2026.
The draft Act
As reported, the draft Cannabis Control Act would register cultivation sites as small, medium or large so their locations can be traced. Estimated A farm with clean records is better placed than one without.
Get the checks done
A farm deal needs legal due diligence on land and structure and a compliance check on certification and records. Our target and partner checks cover the second. See what a compliance audit checks and red flags in a deal.
