Title 19 › Chapter CHAPTER 4— - TARIFF ACT OF 1930 › Subtitle SUBTITLE IV— - COUNTERVAILING AND ANTIDUMPING DUTIES › Part Part I— - Imposition of Countervailing Duties › § 1671a
The agency must open a countervailing duty investigation when it finds enough information to justify one. It also must open an investigation when an interested party files a petition on behalf of an industry and gives the evidence they reasonably have. The petitioner must give a copy to the U.S. International Trade Commission the same day. If the petition only claims a problem with official export-credit rules, the agency tells the Treasury, and Treasury must, within 5 days after the agency starts the investigation, check whether there was a problem and publish its estimate. The agency will send a public copy of the petition to the government of any exporting country named and offer consultations to countries in the Subsidies Agreement. Before deciding to start an investigation, the agency will not take unsolicited comments from people who are not listed types of interested parties, and it will keep draft petitions private. Within 20 days after a petition is filed, the agency must check the petition’s evidence and whether it really represents the industry. In rare cases where the agency needs to poll the industry, it may take up to 40 days. If both checks are positive, the agency starts an investigation. If not, the petition is dismissed and the petitioner is told why. To show industry support, petition backers must account for at least 25% of total domestic production and more than 50% of the production among those who took a position. The agency may ignore positions of domestic producers tied to foreign producers or of importers in certain cases. If support is unclear, the agency will poll or use sampling. Before the decision to start, interested parties can send comments, but the support decision cannot be changed after it is made. The agency must tell the Commission any decision right away and share needed information under confidentiality rules. If the agency thinks a subsidy may break the Subsidies Agreement, it can ask Customs for monthly data on entries until the case ends.
