First sale. Is shipment fee included?

Hello! I have sold my first product and I will fulfill it myself. The problem is I don’t understand if the shipment cost is included or not. I have 1 unshipped order to Holland. I am in Hong Kong.m. Does it mean that the shipment is included if I can’t see any shipping fee line in the order contents? Thanks for letting me know… I really appreciate. Tomorrow I will proceed with the shipment, but I want to know if the shipment will be paid or I have to pay and in this case I’m pretty fucked.
