Thai GACP requirements vs. European GACP for medical herbs


What are the differences between Thai GACP requirements and European GACP?

This is an important question if you are a Cannabis producer for medical and export sector. The clear direction of Thai Government, even in absebce of the Cannabis and Hemp Act, that will be issued and enforced in 2024, is in total control of product through traceability and of quality through Thai GACP and GMP standards.

Thai GACP standards will cover the production until the packaging and primary shipment (the moment producer will load the product on a truck). From there, GMP standards will take over. If you are a producer of cannabis for medical use or recreational (that is considered medical as well), you will need to grow in respect of Thai GACP standards.

If you export, you will also have to take into consideration the standards of Destination Country.

In this table we provide for reference the comparison between Thai GACP according to ” Thailand guidelines on Good agricultural and collection practices (GACP) for medical plants” and EU GACP according to “GUIDELINE ON GOOD AGRICULTURAL AND COLLECTION PRACTICE (GACP) FOR STARTING MATERIALS OF HERBAL ORIGIN”.
