Title 19 › CHAPTER 4 — TARIFF ACT OF 1930 › SUBTITLE IV — COUNTERVAILING AND ANTIDUMPING DUTIES › Part II — Imposition of Antidumping Duties › § 1673d
The agency that checks for dumping must decide within 75 days after its preliminary finding whether imports are being, or likely will be, sold in the United States below their fair value. It can delay that final decision until the 135th day if exporters who account for a big share of exports ask for the delay when the preliminary finding was affirmative, or if the petitioner asks when the preliminary finding was negative. If the final finding is affirmative and “critical circumstances” were claimed, the agency must also say whether there is a history of dumping and injury or whether importers knew or should have known dumping would cause injury, and whether there were massive imports in a short time. The agency ignores any dumping margin that is de minimis. After that, the U.S. International Trade Commission must decide if a U.S. industry is materially injured, threatened with material injury, or if the start of an industry is being held back because of those imports. If imports are tiny, the case ends. Timing rules: if the agency’s preliminary finding was affirmative, the Commission must decide by the later of 120 days after that preliminary finding or 45 days after the agency’s final finding; if the preliminary was negative but the final is affirmative, the Commission has 75 days after the final to decide. If the agency found critical circumstances, the Commission must also say whether imports are likely to seriously weaken any remedy, looking at timing, volume, inventory increases, and other facts. If both the agency and the Commission decide affirmatively, the agency will set estimated dumping margins for the investigated exporters and an “all-others” rate (a weighted average that excludes zero, de minimis, and certain special-calculated margins), require cash deposits or bonds based on those rates, and issue an antidumping order. If either decision is negative, the investigation ends and any suspension of liquidation is ended and deposits or bonds are returned. The agency must publish its findings, share relevant information with the Commission, allow corrections for ministerial errors (simple arithmetic or clerical mistakes), and may make suspensions apply retroactively to unliquidated entries made on or after the date 90 days before the first suspension order.
