I need help mapping products to sales tax categories when no obvious choice exists.

I just stopped using Avatax for sales tax calculation. I now need to map products to sales tax categories in QB. Some Avatax codes have no direct mapping in QB. e.g. "Cocktail Mixes-NoAl <=24% Juice" or "Drug Testing Kit". Or even "Extended Warranty" which could be for a hardware product, not software. How do I map these? (I have a list of 100 Avatax codes with no clear QB equivalent).
