Thailand Cannabis Business Compliance Checklist (2026)

This is the checklist a Thai cannabis business needs to pass inspection and renewal in 2026. Work through every section. Each item traces to a current rule — the April 2026 licensing overhaul, the January 2026 facility and staffing standards, and the ongoing controlled-herb reporting regime. If you cannot tick an item, treat it as a task, not a footnote: the same gaps are why roughly 84.5% of expired licenses did not renew.

Use this alongside the dispensary-to-clinic conversion guide and the license renewal guide, which explain the “why” behind each requirement.

1. Licensing and legal status

• Valid cannabis license under the current rules, with a confirmed expiry date
• Qualifying applicant status — anchored to the health sector (hospital, herbal-product, pharmaceutical, Category 5 extract license, folk-healer certification, or a GACP cultivation site)
• Business registered with the Department of Business Development and tax registration in place
• Ownership structure compliant — minimum 51% genuine Thai ownership; no nominee arrangements
• Licensing basics reviewed in the cannabis license guide

2. Practitioner and staffing

• DTAM-certified practitioner on-site throughout all operating hours (Article 8/1(4))
• Practitioner holds current DTAM cannabis-prescribing certification
• Backup practitioner arranged so illness or leave does not create a coverage gap
• Opening hours aligned to guaranteed certified coverage
• Full detail in the staffing requirements guide

3. Prescription-only dispensing (PT 33)

• Every sale tied to a valid PT 33 prescription, capped at a 30-day supply
• No recreational sales, no walk-up sales without a prescription
• No advertising of cannabis products
• PT 33 process understood — see the PT 33 prescription guide

4. Facility standards

• Segregated, climate-controlled storage — cannabis flower stored separately, elevated off the floor, protected from sunlight, temperature and humidity controlled
• Odor and smoke elimination system — activated-carbon filtration or sealed extraction, with a documented maintenance log
• Premises rights documented — ownership, possessory rights, or written owner consent
• Premises meet zoning requirements (typically away from schools and temples)

5. Product sourcing and quality

• Cannabis flower sourced from GACP-certified farms
• Certificates of Analysis (COA) on file for all products
• THC content accurately labeled; products above 0.2% THC handled under the correct regime
• Import permits in place for any imported product

6. Records and reporting

• Monthly source, usage, and inventory reports to DTAM via forms Phor.Tor. 27, 28, 29
• Complete PT 33 transaction log — practitioner, patient identifier, products, quantities
• Inventory records with batch numbers and supplier information
• Financial records current for tax reporting

7. Tax and insurance

• Corporate income tax, VAT (if over the threshold), and withholding tax handled
• Social Security contributions for registered employees
• Appropriate liability, product, and property insurance in place

Inspection-day quick check

When an inspector arrives, they typically verify:

A note on fees

Fee figures in circulation are unresolved. Commonly-cited business-type license fees (retail ~5,000 / cultivation ~50,000 / manufacturing ~10,000 THB) conflict with the statutory schedule under the Herbal Products Act B.E. 2562 (1,500 / 5,000 / 20,000 / 2,500 THB). Treat all fee figures as reported, and confirm the current amounts with the issuing authority (DTAM / Thai FDA) before you budget or pay.
