Hello. My client sells semi-trailers. There are thousands of products in their WooCommerce store (synced using Zoho). Each one has a taxonomic attribute called "Control Branch" that indicates the city where the trailer is located. The attribute values are codes like "1CA01" which means Irvine, "1CA02" which means Fontana, and so on. They want taxes to be calculated based on this attribute value, so the rate will change depending on the trailer's location. How would I go about doing this? I want to be able to look up a tax rate in WC's standard rates table. I could ignore that table altogether and just put together my own tax table using Advanced Custom Fields, but then the client would have to manually update tax rates from time to time. Thanks in advance.
