From what most of my Euro customers tell me (I have LOTS), if the value of the goods (alone) is under 22 Euro they go through fine (free), if the value is over 22 Euro the the total of item value + shipping are taxed.
A good reason to use stealth postage if you can, obviously it would be easy for them to guess at the shipping charges but apparently they don't or perhaps only in rare cases.
Considering what you are selling you should in most cases be able to ensure that your buyers don't pay any taxes (presuming you don't let high morals get in the way ;-)).
