An expiry review can result only in the repeal or continuation of the duties in force. If measures are maintained, they will normally remain in force for another 5 years. An expiry review cannot lead to a change in the level or form of the duties; these can be changed only by an interim review. If measures are repealed, any duties collected since the initiation of the expiry review will be repaid upon request to the customs authorities.
