How can I add import tax to final price in Shopify?

[revolverbloom]

Hello there,

We sell from the UK to mainland Europe. We pay the import tax ourselves, however we want to simply charge their shipping import tax to the final price before the customer pays. For example the import tax fee in Germany  is 21% off the final sale value and in The Netherlands its about 9%. How can I get this added as a rule within Shopify?

Anyone have any answer for this?
