Kratom on airports

Hi fellas, I have a question about kratom in Germany. I found out that it is similar to here 🇨🇿, legal but not sold as a dietary supplement/medicine but as a collector's item. My question is, at the end of the year, I'm flying to Germany for three days on business, with a couple of meetings there one day and then back in two days, and I just want to ask if anyone has experience with transporting kratom by plane. I won't have much time to buy it there, but I don't want to be delayed at the airport because of it. I would appreciate any of your experiences. Thank you and have a nice day.
