GACP vs GMP: Which Standard Does Your Farm Actually Need?
These two acronyms get mixed up constantly — and the confusion leads farms to invest in the wrong things. The short answer: GACP is the farm's standard; GMP is the factory's standard.
Drawing the line
GACP (Good Agricultural and Collection Practices) covers everything from seed/seedling through cultivation, harvest, primary drying, and storage of the herbal raw material. In Thailand it's certified by DTAM.
GMP (Good Manufacturing Practice) starts where GACP ends: processing, extraction, manufacturing into medicinal products, packaging, and factory-grade quality control — regulated by the Thai FDA, with the stricter EU-GMP governing European export markets.
| GACP | GMP | |
|---|---|---|
| Applies to | Farms / cultivation & collection sites | Processors / manufacturers |
| Scope | Seed → grow → harvest → drying → raw material | Raw material → extraction/processing → product → packaging |
| Core focus | Cultivation records, inputs, environment, traceability | Clean rooms, validated processes, analytical QC |
| Who needs it | Every farm selling into the medical market | Processors, extractors, drug manufacturers |
The quality chain: why both exist (held by different people)
The medical cannabis and herb market runs as a chain: farm (GACP) → processor (GMP) → dispensary/clinic/exporter. A GMP-certified buyer must prove their raw material came from a quality-controlled source — so they buy only from GACP farms, and they typically ask to see the cultivation records for the batches they purchase.
This is where digitally documented GACP farms hold an edge: when a GMP buyer requests batch documentation, the farm that prints a complete batch dossier in one click closes the deal faster than the farm digging through paper binders for a week.
Should a farm invest toward GMP?
Usually no. If your business is growing and selling raw material or flower, GACP is your standard. GMP becomes necessary only when you move into processing or extraction yourself. The exception worth planning for: if long-term you aim at European export, EU-GMP buyers audit back to the source farm — and your record-keeping standard from day one is what they'll evaluate. Starting strict is always cheaper than retrofitting.
