We are almost set, still, some issue exists with commercial invoice generation, as we cannot see any harmonized code. Here’s FedEx comment on this:

Your request does not have any HS code field after the Country of Manufacture field.


Once you have added this to your request, it will be printed on the invoice. Please also note that you have to enter the HS code yourself. You need to add this information manually to your ship request.

We have incorporated HS Tariff number (Harmonised Code) at the product level in the latest version of the plugin (see screenshot below). You can provide a value for the HS tariff number and then provide the request and response to FedEx team.
