Best site to buy from that won't have any problems going through UK customs?

I’m still waiting for Kratombird to come back online. They were in Sweden and never had any trouble with customs but they are moving location due to it being banned there (unfortunately I think it will be in the Netherlands now, but I’m just guessing). Even if they do pop up in the Netherlands I will still order from them as their kratom is as good as anywhere else and better than some others. They are also the cheapest €80 for 1kg and labelled as indigo powder, even if customs open the package,
