How do foreign trade companies and factories settle foreign exchange in dollars?

It depends on whether the factory should refund the tax. The factory doesn't write off the tax refund, and it doesn't matter whether it receives US dollars or RMB. All the same. If the factory wants to refund the tax, it is best to remit the US dollars directly from abroad to the factory. In the case that both parties have domestic US dollar accounts, even if the foreign trade company transfers US dollars to the factory, the US dollars received by the factory cannot be refunded.
