I've recently been getting a lot of tax bills come back on me from Canadian customers refusing to pay their taxes & duties. At the end of the day, FedEx is requiring us to pay these.

It looks like there is a way to estimate the taxes & duties through the FedEx api ( https://www.fedex.com/content/dam/fedex/apac-asia-pacific/downloads/fedex-api-estimated-duties-taxes-en-apac.pdf ).

Is there currently a way to estimate the amount & add the estimated amount to an order total? I can't keep doing business with Canada if this continues, it's been $1000's that have come back on us as a result of them refusing to pay what was owed.

Looks like if it's not in place now, coming down the pipeline will be a mandatory taxes/duties paid by the shipper. ShipStation today had this ticked by default for my international shipments. A post about it here: https://community.shipstation.com/t5/ShipStation-Features/FedEx-DDP-Forced-even-though-disabled/td-p/29640

There will need to be a way to properly calculate the duties and taxes for shipments if the couriers are going to force this on us.

Also, if there was a new field for harmonization codes to be input into a product and passed through to ShipStation that would also be of great help.
