1. Where there exists sufficient evidence presuming the existence of the fact of dumping and the fact of material injury, etc. caused thereby with respect to the relevant goods;
2.

(2) In any of the following cases, provisional anti-dumping duties paid shall be refunded or the offered security shall be rescinded, as prescribed by Presidential Decree:
1. Where an investigation has been closed after a request for the assessment of anti-dumping duties on goods against which the provisional measure has been taken, has been withdrawn;
2. Where a decision has been made on whether anti-dumping duties are assessed on goods against which the provisional measure has been taken;
3. Where the undertaking provided for in Article 54 is accepted.

1. Where the undertaking provided for in Article 54 has been accepted after the existence of the fact of dumping and the fact of material injury, etc. caused thereby are made definite as a result of conducting an investigation on such dumping of the relevant goods and injury to the industry caused thereby;
2. Where anti-dumping duties have been assessed retroactively in accordance with the proviso of Article 55.[This Article Wholly Amended on Dec. 30, 2010]
