Global surcharge WooCommerce exclude VAT - php

Question

I made a global surcharge in PHP for WooCommerce, because all of our customers have to pay a fee for special delivery.
Is there a way to make the fee ignore VAT?
When I write 15 it adds VAT to the number. I'd just like for the number I write to be the fee.
TL:DR - MAKE SURCHARGE INCLUDED VAT
// Packing fee
add_action( 'woocommerce_cart_calculate_fees','wc_add_surcharge' );
function wc_add_surcharge() {
global $woocommerce;
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
$county = array('DK');
// change the $fee to set the surcharge to a value to suit
$fee = 15;
if ( in_array( WC()->customer->get_shipping_country(), $county ) ) :
$woocommerce->cart->add_fee( 'Emballage pant', $fee, true, 'standard' );
endif;
}

Answer 1

To make the fee ignore Vat you need to remove the 2 last arguments as they are related to Taxes (the third argument is false (not taxable) by default ):
Also global $woocommerce; and $woocommerce->cart as there is a missing $cart argument in this hooked function. So try this instead:
// Packing fee
add_action( 'woocommerce_cart_calculate_fees','wc_add_surcharge' );
function wc_add_surcharge( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
$county = array('DK');
// change the $fee to set the surcharge to a value to suit
$fee = 15;
if ( in_array( WC()->customer->get_shipping_country(), $county ) ) :
$cart->add_fee( 'Emballage pant', $fee );
endif;
}
Code goes in function.php file of your active child theme (or active theme). Tested and work.
