in my opinion small scale coke smuggeling from SA to EU is not feasable for a extended time. Your connect here will be busted soon. There is a reason the cartels get fucking rich and not a whole lot of small scale post-smugglers.
If you want to try it anyway you shouldn't send small packages via express, private looking, with a stated worth less then 150€. Also don't liquidize and then recrystalize it in cloth or smth like that or send it liquid cause then it would even be more camouflaged.
If you want to make it a bigger operation which I also not recommend, I would never try to get a homeless person in europ to register a business online (should be possible in most european countrys) including an EROI-Number for which you probaly also need the persons tax-ID. Don't the same. Don't employ those CC-Fraud guys who sell real Onlinebank-Accounts bc they know there way through the posssible identity check processes. Never send Wooden boxes with typical Brazilian stuff to europ via a freight company. Bc then your european partner "just" has to employ a trucking company (which he has to pay with a Bank-Account from those online guys) which delivers those boxes to a place where a truck of loading boxes would fit in (i.e. wholesale market).It would be worse to put some technical stuff inside so you can check if the box was tempered with. Also data should be always transmitted to you directly and not postzed to an obscure Twitter-Account...
I WOULD DO IT! ITS AN GOOD IDEA!
