UPS aditional charges for NDA and 2DA only - per item

I have a real brain teaser here. I have already gone through a bottle of Advil...

I need to charge additional fees for only one of my product if it ships by UPS NDA or 2DA, otherwise it receives standard rate charges.

Is there a way to add a handling fee on a per item basis if it falls into the UPS Air Shipping category?

If nothing else I have learned many tips and trick reading through the forum looking for this answer

Thank you for any help.

You would need to find this section of code in the United Parcel Service ups shipping module:
/includes/modules/shipping/ups.php

        $methods[] = array('id' => $type,
                           'title' => $this->types[$type],
                           'cost' => ($cost + MODULE_SHIPPING_UPS_HANDLING) * $shipping_num_boxes);

And customize what is used in place of:
MODULE_SHIPPING_UPS_HANDLING

When the $type is the same as the code(s) ... see codes in module ... match your customized handling charges ...

NOTE: shipping modules are NOT overrideable, however, you can clone them so that your custom module does not get overwritten with each upgrade ...
