The Uruguay Round Agreements Act requires the Department of Commerce to revoke an antidumping or countervailing duty order, or terminate a suspension agreement, after five years unless the Department of Commerce and the USITC determine that revoking the order or terminating the suspension agreement would be likely to lead to continuation or recurrence of dumping or subsidies (Commerce) and of material injury (USITC) within a reasonably foreseeable time.

The Commission’s notice of institution in five-year reviews requests that interested parties file with the Commission responses that discuss the likely effects of revoking the order under review and provide other pertinent information. Generally within 95 days from institution, the Commission will determine whether the responses it has received reflect an adequate or inadequate level of interest in a full review.
