woocommerce_shipping_tax_class │ filter-hook │ WC 10.5.0

Filters the shipping tax class before calculating tax rates.

This filter allows plugins to modify or replace the shipping tax class that will be used to calculate shipping tax rates. It fires after core logic determines the tax class but before rates are looked up.

Usage

add_filter( 'woocommerce_shipping_tax_class', 'wp_kama_woocommerce_shipping_tax_class_filter', 10, 4 );
