I was called by a courier and he delivered the package at my door so most likely it will be the same for you since you also paid that expensive shipping.
If caught you might have to pay a fine since it's the first occurrence. However in case they show up and question you, just say you got it for some relative in the country side who has meat and isn't very internet savvy to order themselves. Whatever they say don't admit it was for CTB.
You might get lucky and they won't open yours. I doubt they open every single package. Yeah they might open even the ones from EU but most likely they do it selectively.
Another option: see what happens. If there's just a courier showing up,pick the package and after don't keep it where you stay. Store it somewhere else for a month.
In case police comes with the courier or you are invited somewhere to pick the pack and asked questions, you could also deny you ordered. You have no idea about it and didn't order anything like that.Best is to order something else from the internet now(ebay,amazon etc) and if they invite you for questions/show up at your door,just say you expected your order from ebay/amazon/whatever and don't know anything about any Sodium Salt order or IC. Could also print the payment for ebay/amazon/whatever site order just to have it handy. Delete your internet history and e-mail you got from IC.
So,just see how things go and you chose what to do at that time. If you deny and say you didn't order and it is a mistake there is nothing they can do to you. Hope this helps.
P.S: I'm pretty sure i've seen posts of people from Germany who got their N orders just fine. So don't stress too much.
