The Difference Between EU-GACP and Thai-GACP, and why bother…

European Flag and Thai Flag in the sky
European Flag and Thai Flag in the sky

The European-GACP may seem inferior to the Thai but there are some key differences. The Thai-GACP Standard is overall more specific and requires proper audits, however the European version is accepted more readily in most export markets, and Thai-GACP may not be enough. If you wish to skip the reading and get started, we recommend our self-assessment tool here: https://gacpasia.com/our-services/self-assessment/.

If you’re involved in cannabis production destined for medical or export sectors, this question carries immense weight. Even in the absence of the forthcoming Cannabis and Hemp Act, due in 2024, the Thai Government has set a definitive course emphasizing stringent control over products via traceability and maintaining quality through adherence to Thai GACP standard, which is approved by the TFDA.

Generally, GACP standards oversee the entire production chain, encompassing cultivation through to packaging and the initial shipment (up to the point where the product is loaded for shipment). Following this stage, the responsibility shifts to GMP standards, GMP is applicable earlier if the grower decides to process the harvest.

If you wish to export, you must meet the standard of the receiving country. As the EU is the most (and best) regulated, GACP Asia have chosen to follow EU Regulations for GACP to ensure you are able to export your product anywhere.

To show you the differences, we’ve prepared a comparison table between TH-GACP, as outlined in the “Thailand guidelines on Good Agricultural and Collection Practices (GACP) for medical plants,” by DTAM and EU-GACP as delineated in the “GUIDELINE ON GOOD AGRICULTURAL AND COLLECTION PRACTICE (GACP) FOR STARTING MATERIALS OF HERBAL ORIGIN” by the EMA.

While we’ve taken as much care as possible to make this accurate, we’ve found that the Thai version is more specific, so if you can obtain Thai GACP, EU GACP should be easy (However if a Thai grower wishes to export to the European Union, we would recommend that they also obtain an EU GACP Certificate as well as a Thai GACP Certificate). Further, as one is based on the other, they are fairly similar, and we’ve been able to copy the Table of Contents main issues:

We further note that for growers in Thailand looking at international markets, the target market should be the consideration for the GACP Certification, as well as the domestic GACP. GACP Asia can help you achieve the required certifications and advise you on the procedure for the export of the end product.
