Different shipping for different taxgroups

In my shop I have different geozones, which means different shippingrates.
I offer my Dutch customers a fixed rate, and would love to do the same for, for example, Belgium customers.
I have only one option for a fixed price, anyone who knows how to get a fixed price for the other countries?

I could not find anything so even a topic that can help me is okay

Thanks in advance.

If you just need flat rates for different geo zones, you can do that using the built-in Weight Based Shipping. Here's a tutorial on how to do it:

If you need more criteria on how you create your shipping rates, such as based on total or quantity, then you could get Formula-Based Shipping to do that. It has a variety of rules you can use to create different formula-based rate types.

Feel free to take a look at the screenshots and demo site, and if you're interested let me know at www.getclearthinking.com/contact if you have any further questions.

I have been working on this for ages now and am not able to get it to work...
I just don't get why.....

If you're using Formula-Based Shipping, please contact me here for support:

If you're trying to use the built-in Weight Based Shipping, post some screenshots here of your setup in the extension, and you setup for your geo zones (in System > Localisation > Geo Zones). I'll see if I can suggest any adjustments to your setup.
