The WTO Anti-Dumping (AD) Agreement requires that anti-dumping duties be reviewed at least every five years (Art. 11.3); pursuant to this requirement, domestic trade authorities in the United States are charged with the task of making a determination as to whether, after five years, revoking the duties would be likely to lead to continuation or recurrence of dumping (Commerce) and of material injury (US International Trade Commission, or USITC). This is called a Sunset Review; a negative determination of likelihood, either with respect to dumping or injury, will result in the duties expiring, the “sun” setting, as it were.
