Your supplier has two options when charging you for shipping costs for your inventory order. They can either charge you for shipping prior to the creation of your goods and include it on your initial invoice, or they can choose to wait until your goods are ready to ship. It is common for Suppliers to send a follow up invoice for shipping at the time when the goods are ready to ship. In either case, you will be responsible for shipping, duties, and tariff costs associated with shipping your inventory order.
