A better enterprise can apply to the foreign exchange bureau for approval and directly transfer foreign exchange to another domestic enterprise without any business background. This general enterprise can't do it, but it can only be transferred to its own account, with the same name and nature. On the premise of goods trade, the enterprise itself must have the right to operate foreign trade, have a foreign exchange list of goods trade filed with the foreign exchange bureau, and the goods come in through the customs (that is to say, your foreign exchange payment data should match the data imported by the customs, and the principle of domestic foreign exchange payment is the same), and then you can submit the customs declaration or contract invoice. Trade in services is relatively loose. You don't need any information for less than $50,000. For more than $50,000, you need to provide a contract invoice, and you need a tax return issued by the IRS when paying taxes. Under the capital account, it is basically necessary to register with the foreign exchange bureau and pay foreign exchange at the bank within the registered limit.
