Thank you for getting in touch with your question. Can you tell me more about these "freight costs" you've referenced, please? Are these shipping rates you've added in a shipping profile in Settings > Shipping and delivery, or are these additional costs you require customers to pay alongside shipping charges? If possible, could you potentially share here a screenshot that shows the part of an order that includes a tax charged on the shipping/ freight fees?
