Excuse me, do any friends know that air cargo from Guangzhou to Vietnam can be refunded for export? (Transportation is a tax-refundable product)

As long as you go through the customs formalities, you can declare the tax refund. If it is small in size and light in weight, you can collect the money by air, and state in the bank report that it is the sample that the customer needs. In this way, you can deduct the input, and you don't have to go through the tax refund formalities, and you don't have to go to the safe to run this trip. However, it is rare. Second, you need to go through the customs declaration form. Third, you need to provide formal air transport documents when submitting information to the bank.
