If it is a freight forwarder, you have to let the freight forwarder know your goods first, "name, tax number, business unit, whether there is wood, whether there is fumigation, whether there is a logo, 20 feet /40 feet, weight, whether there are other documents besides the invoice contract of the box list, and special precautions", and then you can let him quote you ... Note: if it is bulk groceries and special boxes, you must entrust an application.
If it is a customs broker, it will be very simple. The import and export customs broker is tens of dollars, but you have to give him some profit margin ~ generally, he is given 90- 120/ ticket for export and 120- 150/ ticket for import.
