First of all, your goods have left the country, unless you have definite evidence to prove that your HS code is really wrong and has been approved by the customs, in which case, you can apply for a change of the bill. Of course, there are also cases where the customs take the initiative to ask you to change HS, and no evidence is required.

Secondly, after the customs agrees to change, there are three situations:

1, the tax rebate rate of the new HS code remains unchanged, just change the code directly;

2. The new HS code has a high tax rebate rate, which is not bad. After you change the bill, you can apply for a new tax refund form and go to the tax bureau to make up the difference for you.

3. The new HS code has low tax refund rate and is troublesome. You need to calculate the tax refund difference of two yards, and then go to the tax bureau to return the excess to the tax bureau. The inland revenue department will give you a certificate to prove that you have refunded the overpaid tax. Apply to the customs for changing the HS code with the tax bureau certificate.

Of course, if there is no tax refund, the whole ticket will not be refunded, and individual goods will not be refunded.

Hope to adopt! !
