Three sets of letters show up on every serious supplier page. Here is what each one covers, without the jargon.

Where each one applies
GACP covers how the plant is grown and collected. GMP covers how it is processed and packed to a pharmaceutical standard. GPP covers good practice in distribution.
Why buyers ask for them
Together they prove the flower was grown, made and moved properly. Which ones you need depends on the market you sell into.
The letters are not decoration. Each one answers a different question a regulator will ask.
