Esto es lo que dicen en su web en relación al IVA

"International VAT/GST
If we are required to collect VAT/GST fees by your country, you will see the fee in your shopping cart and your package will be marked accordingly. If your country does not require us to collect any taxes on your order, please be prepared to possibly pay any fees associated with importing merchandise from the USA. We are not and cannot be responsible for what your country charges. We do not declare packages at less than paid value, and we do not make special accommodations such as opening your package and only shipping discs."

Esto da a entender que ellos se encargar de cobrar el IVA, puesto que te lo cobran. Pero experiencia personal, no tengo.
