Customs & Excise 101 - for purchases outwith the EU

I can testify to what has been said about Your Shaving. Been using them a while and since Brexit (touch wood) never been hit with any charges, hence why they are one of my favourite vendors
 
I am looking at getting something from raisongoodfellas.eu and having it shipped to austria - will there be any customs / duties levied at austria?
I'm not sure what the limits are in Austria and whether it has a similar limit to the UK or not, so it might be dependent on the total cost of the order.

But to give you a rough idea I would try the following website, you get 5 free calculations a day without having to register an account. This has been pretty accurate with shipments to the UK, apart from the courier processing charges obviously as they are company dependent.
