If the freight is not much, it is cost-effective to pay RMB, because paying US dollars requires a US dollar account first, and then the starting price. More cost-effective, less cost-effective. Some freight forwarders who pay RMB will have high prices. For example, it's only 6.8 now, and he wants you to pay according to 7. 1, otherwise he wants you to pay US dollars. If you meet an accommodating person, you will follow the quotation of the day. As for the currency of the invoice, it doesn't matter. You can also pay RMB in dollars, as long as the other party accepts it.

Problem supplement: Freight forwarders also have storage fees. Is this fee reasonable?

If you send the goods to the warehouse and the freight forwarder packs them, there will be this storage fee or packaging fee. If the container is door to door, there is no such charge. This fee is generally RMB, not US dollars.
