The total amount you collect from a customer is taxable in most countries (EU/UK/Canada/Mexico/Australia/etc). (Product Total, shipping paid by customer, insurance paid by customer, minus discounts given to customer).
The ONLY thing Shipstation includes on the USPS and UPS customs declaration information is the product total.
I brought this issue to the attention of support & the response was "Ultimately, these customs documents are generated by the carrier, outside of ShipStation, and returned to us along with the label. We are currently limited in how much we can modify them."
This is not correct. You have to provide these amounts to the USPS and UPS Apis in order for them to show up on the document.
There's a spot for shipping charges on the USPS labels and UPS customs form. Shipstation has this information in the order whether it's a manually created order or an imported order. They're just leaving it blank.
While the customer is going to get a lower customs bill, shippers knowingly providing a false shipment value is customs fraud. I wouldn't advise using shipstation for international shipments where you are charging the customer for shipping or insurance. If you're offering free shipping to customers, then it's not an issue.
