Removing the Additional information tab

To remove the 'Additional information' tab from the single WooCommerce product add this to the end of your child theme:

function uxs_child_remove_product_tabs( $tabs ) {
 unset( $tabs['additional_information'] ); // Remove the additional information tab
 return $tabs;
}
add_filter( 'woocommerce_product_tabs', 'uxs_child_remove_product_tabs', 98 );
