This view of the Tax Code Information window allows you to set up codes for import duty on goods being brought into the United States. Import duty codes function a bit differently than other types of tax codes - they usually are assigned only to line items on purchase orders, but the tax amount calculated won't appear on the purchase orders, since the import duty is payable to the federal government, not the vendor who will receive the purchase order. Instead the import duty will be tracked using the linked account you specify here, and you can make a separate payment to the government based on the balance of your linked account.
