The customs has the right to detain some goods that are not allowed to be imported or whose declared value is obviously lower than the actual value of the goods. Your question mainly depends on how to write the reasons on the debit note. If the goods are not allowed to be imported because of their nature, then don't take them out and wait for the customs to destroy them. If it is because of the tariff problem, it will be easier to solve. You can get the goods back by paying the corresponding amount of tariff directly.
