How to change Tax-class for 6000 products

Question

I've about 6000 products with empty TAX-CLASS, what is the best approach to correct it to a proper TAX-CLASS. All the products will get the same tax-class insteed of an empty one

Answer 1

Go to Catalog->Manage Products.

Select All Products and select action is "Update attributes" then submit

In attributes tab you see "Tax Class", select tax class then save it.

Answer 2

This is my approach:

1. Get the entire collection of products

2. In a foreach loop load the instance of product and set the tax class.

You can take a look in tax_class table to see the corresponding id for each tax class.

   <?php
require_once ( "app/Mage.php" );
Mage::app();

Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
$products = Mage::getModel('catalog/product')->getCollection()->addAttributeToSelect('*');
foreach($products as $product) {
    //$product = Mage::getModel('catalog/product')->load($prod->getId());
    try{
        if($product->getTaxClassId() == 0){
            $product->setTaxClassId(2); //tax class (0 - none, 1 - default, 2 - taxable, 4 - shipping)
            $product->save();
        }
    }
    catch(Exception $e){
        Mage::log($e->getMessage());
    }
}

Save this script under your root instalation of magento, in a php file and run it

Answer 3

The script from Alex will ruin every product when it already has a tax class or is declared as shipping. Don't run it this way! Use some filters while grabbing your collection or use an if statement in the loop.
