Five-year reviews of all antidumping and countervailing duty orders that were issued prior to 1995 (known as "transition" reviews) were initiated by the Department of Commerce beginning in July 1998 and completed by both Commerce and the Commission in February 2001, several months prior to the statutory deadline of June 2001. Five-year reviews of all antidumping and countervailing duty orders that are issued after January 1, 1995, including any continuation orders, are initiated by Commerce by approximately 30 days prior to their five-year anniversary.

The Commission will institute its five-year review and set its schedule in a published Federal Register notice that will be effective the same day as Commerce's initiation of the five-year review. The Commission’s notice in each review will be posted in the Five-Year (Sunset) Reviews Database.

Approximately 95 days after publication in the Federal Register of the Commission's notice of institution of the five-year review, the Commission will decide whether to conduct a full or expedited five-year review. If the Commission decides to conduct a full five-year review, it will typically complete the review within 360 days of initiation. However, if interested party responses to the Commission's notice of institution are inadequate, the Commission can make an expedited determination within 150 days. Both Commerce and the Commission have the authority to extend these deadlines by up to 90 days in all transition reviews and other extraordinarily complicated cases.

In five-year reviews, the Commission determines whether revocation of the antidumping or countervailing duty order would be likely to lead to continuation or recurrence of material injury to the U.S. industry. If the Commission’s determination is affirmative, the order will remain in place. If the Commission’s determination is negative, the order will be revoked.
