Problem with taxes, does not associate country

Prestashop version 1.7.4.2

Hello everyone, I am developing a module.

This module reads the product taxes

$product = new Product($id_product);
$id_group= $product->id_tax_rules_group;
$taxes = TaxRule::getTaxRulesByGroupId($id_lang, $id_group);

Check the country and choose the tax for that country

foreach($taxes as $taxs){
	if($taxs["country_name"] == 'spain' or $taxs["country_name"] == 'españa'){
		$tax = ($taxs['rate'] /100) + 1;
	}else{
		$tax = 1;
	}
}

The problem is that in the information read, it is always null in the country field

var_dump($taxes);

[0]=>
  array(10) {
    ["id_tax_rule"]=>
    string(3) "270"
    ["country_name"]=>
    NULL
    ["state_name"]=>
    NULL
    ["rate"]=>
    string(6) "21.000"
    ["zipcode_from"]=>
    string(1) "0"
    ["zipcode_to"]=>
    string(1) "0"
    ["description"]=>

    ["behavior"]=>
    string(1) "0"
    ["id_country"]=>
    string(2) "36"
    ["id_state"]=>
    string(1) "0"
  }
  [1]=>
  array(10) {
    ["id_tax_rule"]=>
    string(3) "249"
    ["country_name"]=>

    ["rate"]=>

    ["id_country"]=>
    string(1) "3"

    string(1) "0"
  }
