These are reviews that the Commission and Commerce are required to undertake at five-year intervals under section 751(c) of the Tariff Act of 1930 (19 U.S.C. 1675(c)) with respect to outstanding countervailing duty and antidumping duty orders. Section 751(c) requires that countervailing duty and antidumping duty orders be revoked, and suspended investigations be terminated, after five years unless the U.S. Department of Commerce determines that revocation or termination would be likely to lead to a continuation or recurrence of a countervailable subsidy or dumping, and the Commission determines that revocation or termination would be likely to lead to a continuation or recurrence of material injury to the domestic industry within a reasonably foreseeable time. If either agency makes a negative determination, Commerce must revoke the order. If both agencies make affirmative determinations, the countervailing duty or antidumping duty order remains in place.
