Problem may be at sending data....

     $(".product").on('change', function(){ 
    var policy= "gggggggggggg";
    //var base_url = 'window.location.origin';
//alert(policy);
  $.ajax( {
  type: "POST",
   url:<?php echo base_url('sales/index.php/Add_AMC/Insurance_chg');?>,
  data: {policy:policy},
  success: function( response ) {
    alert(response);
  }
});
});

OR you can send your data as..

data:'policy='+policy,

In codeigniter you can use the base_url() by loading the url helper.So not need to define base_url like this... So change

url: base_url+"/sales/index.php/Add_AMC/Insurance_chg",

to

url:<?php echo base_url('sales/index.php/Add_AMC/Insurance_chg');?>,
