title: Add fee to woocommerce cart
body: <p>I would like to add a fee to my cart when the customer has a specific billing country. For example Belgium (BE)</p>
  
  <p>I found this code to add a fee by default. 
  Could anyone help me with an IF formula or something, so that it is only applied when the billing country = BE ?</p>
  
  <pre><code>add_action( 'woocommerce_cart_calculate_fees','woocommerce_custom_surcharge'    );
  function woocommerce_custom_surcharge() {
  global $woocommerce;
  
  if ( is_admin() &amp;&amp; ! defined( 'DOING_AJAX' ) )
      return;
  
  $percentage = 0.01;
  $surcharge = ( $woocommerce-&gt;cart-&gt;cart_contents_total + $woocommerce-&gt;cart-&gt;shipping_total ) * $percentage;    
  $woocommerce-&gt;cart-&gt;add_fee( 'Surcharge', $surcharge, true, '' );
  
  }
  </code></pre>
