Customs shall determine the tariff classification of the goods in line with the result of advance ruling if the actual goods that have arrived at Customs are identical to those which have been reviewed in an advance ruling. However, this is not applicable if the Applicant has provided incorrect or false information that has affected the result of the advance ruling.

The Regulations shall take effective from the date of promulgation.
