Get current tax for product

How can i get current tax rate for a Product in Shopping Cart ?

I had tried with;
  var cart = _shoppingCartService.GetShoppingCart(_workContext.CurrentCustomer, ShoppingCartType.ShoppingCart, _storeContext.CurrentStore.Id)
   foreach (var row in cart)
                {
                }
I can get all other info from Products but not tax rate, i can  only get taxid
