Without the right to import and export, you can also find a freight forwarder to export goods. My impression is that Form A and Form CO will not come out with the bill of lading before the ship leaves.

If the export does not require customs declaration, directly write tt before shipment or TT after sight on the purchase and sale contract. Before delivery and after inspection, customers will pay you directly. You shouldn't care about anything else.

The invoice and packing list used for customs declaration are different from the domestic value-added tax stamps, and are only used for customs declaration and have no special significance. Just write truthfully.

If you can't receive the US dollars, you will find someone else to collect them, and there will be some handling fees. It has no impact on your company.
