In Germany and as far as I know also in most other EU-countries SN can only be sold to companies, butchers, restorers and laboratories. When you want to place an order they ask you to send a copy of a document that proves that you are one of the mentioned. I know only one official dealer for all kind of chemicals (no black market) in a EU-country (not Germany) that sells to anybody without this document and ships worldwide. The SN is made by a brand name german company. I ordered there and didn´t have any problems to receive it in the EU-country where I live. There was a "dangerous goods" sticker attached to the outside of the parcel.
I don´t know what happend to the guy I mentioned. He wasn´t online since that happend end of last year. He is charged with import of an illegal substance.
