Hi, so I have set up VAT on magento, but it is currently applied to everything (we sell adult and childrens clothing) so i need the childrens clothing to not have VAT applied.
I have set one product manually to "none" in the tax class and exported to csv, the TAX_class_name is then set to "0".
I then tried to set all applicable products to "0" and upload via csv but it has not changed the products.
is there another way to go about this?
