At present, the export of enterprises is such a procedure. Before you want to export, you should book the shipping space, then go to the foreign exchange administration to get the verification form, then load the goods, declare the customs and submit the form on the website of the foreign exchange administration. If you want to refund the tax, you should contact the IRS for the refund within three months from the date of export with the special tax refund for the customs declaration at that time, and then write off the foreign exchange with the foreign exchange settlement memo to prove that the foreign exchange has been collected. The difference between the allowed settlement memorandum and the total amount declared at that time was $500.
