I've got this working in my store for good classified as dangerous goods.
We want to add $40 charge including tax.
So I have set the value of $handling_special to be 36.36 which is working well, however I also need to know where to put the code to add the 10% tax to this.

We offer free freight on all orders over $200 so adding the $handling_special charge to the shipping value is pointless as it gets set back to zero when the order gets over $200. Any help much appreciated.
