Cannabis seeds in Thailand: buying, importing and selling legally
Thailand Cannabis Report · Reefers Club Co., Ltd. · Last checked 31 October 2026
Seeds are where every cannabis business starts, and they sit under a different law from the flower. Cannabis and hemp seeds are controlled seeds under Thailand's plant laws, administered by the Department of Agriculture, not by DTAM.
The legal status of seeds
When the plant left the narcotics list on 9 June 2022, seeds stopped being narcotics too. Since August 2021, cannabis and hemp seeds have been controlled seeds under the Plants Act B.E. 2518 (1975), with quality standards for seeds that are traded. Verified
Importing seeds
Seed imports must comply with the Plants Act and the Plant Quarantine Act B.E. 2507 (1964). The Department of Agriculture publishes the import conditions for cannabis and hemp seed, and importers need its permits and phytosanitary paperwork. Estimated Bringing seeds in a suitcase is not the same as importing them lawfully.
Selling seeds
Traders in controlled seeds, including importers and collectors, must follow the Plants Act and its bylaws. Verified A shop that sells seeds alongside flower answers to two regimes: the Department of Agriculture for the seeds and DTAM for the flower.
From seed to sale
- Growing: Thai nationals may grow the plant, but foreign-majority companies cannot cultivate, because cultivation is restricted under the Foreign Business Act. Verified
- Selling flower: needs a DTAM licence, and licensed shops can only buy from certified sources: a GACP-certified farm or a harvest with its own laboratory certificate of analysis. See GACP certification.
- Hemp: has its own definition and uses. See hemp vs cannabis under Thai law.
