This is because of the destination, which in your case was the USA. You're lucky you don't have to pay the VAT, but unfortunately the purchasers in every destination that has a VAT system in place, will have been charged the relevant VAT rate at Johannes checkout.
So it's the destination that counts when it comes to VAT, though I must admit it has always baffled me how, for example, the UK can force USA-based businesses to charge VAT. One would naturally assume, that yourself and Urklang are both governed solely by USA law, not EU or UK law - and that's the way it should be IMHO.
Unfortunately, they must have something in place to prevent that, and to force the transfer of taxes, otherwise every non-VAT country could basically stick two fingers up and refuse to charge VAT.
