If you operate one site across multiple regions, you can use the localizedTaxClassId to define different tax class Ids for the same product in different locales. The new attribute eliminates the need to map a different tax rate for each product that requires a specific tax handling.
How: The attribute is a global product preference. To change your system preference to use the localizedTaxClassId, in Business Manager, select . Check Localized Tax Class for Product. The taxClassId is the default for SFRA and SiteGenesis sites.
Note The taxClassId attribute is not changed or deprecated. You can provide values for both
attributes, but only the active attribute is used.
