Add packaging weight based on product weight?

[epmkevin]

How can I add a packaging weight to the total product weight that is different based on the total product weight?

For instance, the product weights are 250 and 500 grams.
If the total order weight is up to 2 kg, the box/package weight will add 1.3 kg.

If the total order weight is 2.1 - 3.0 kg, the box/package weight will add 1.5 kg.

If the total order weight is 3.1 to 12 kg, the box/package weight will add 3.5 kg.

How can I add these weights to the total shipping weight that is sent to FedEx?

Let me know if what I have posted makes sense or if it requires further clarification.

thanks!

If you're using the standard FedExDC module, or my FedExv2 module, I don't think there is a way to do this.  It sounds like you need a customized solution.  I could add this "padding" feature to my FedExv2 module, for a fee.  PM/email me for a quote.
