Title 19 › Chapter 4— TARIFF ACT OF 1930 › Subtitle SUBTITLE IV— COUNTERVAILING AND ANTIDUMPING DUTIES › Part I— Imposition of Countervailing Duties › § 1671a
An investigation must start when the agency in charge finds that the information it has supports a formal probe into whether a countervailing duty is needed. A case also begins when an eligible domestic party files a petition for an industry that claims the needed facts and gives the information it reasonably has. The petitioner must give a copy to the U.S. International Trade Commission the same day. If the petition only rests on a break of an international rule about official export credits, the agency must tell the Secretary of the Treasury, who then has 5 days after the probe begins to decide if a break occurred, estimate its value, and publish that finding. The agency must send a public version of the petition to any government named and offer consultations to countries that are party to the Subsidies Agreement. Before deciding whether to start, the agency will not accept unsolicited comments from people who are not eligible parties, and draft petitions kept for review must be kept confidential. Within 20 days after a petition is filed, the agency must check, using readily available sources, whether the petition shows the required elements and was filed on behalf of the industry. In rare cases that require polling, the agency may take up to 40 days. If both checks are yes, it opens an investigation. If not, it dismisses the petition, ends the case, and tells the petitioner why. To count as filed on behalf of the industry, supporting domestic producers or workers must make up at least 25% of total domestic production and more than 50% of the production among those who took a position. The agency may ignore the views of domestic producers who are related to foreign producers or who are importers. If support over 50% is not clear, the agency will poll the industry or use a valid sample. Potentially interested parties may comment on support before the decision, but the support finding is final once made. The agency must tell the Commission right away about its decisions and share relevant information under rules that protect confidential material. If the agency later has reason to think the subsidy may violate the Subsidies Agreement, it can ask U.S. Customs and Border Protection to collect and send data on entry volume and value at least once every 30 days until a final decision, the case ends, or the request is withdrawn.
