Title 19 › CHAPTER 4 — TARIFF ACT OF 1930 › SUBTITLE IV — COUNTERVAILING AND ANTIDUMPING DUTIES › Part I — Imposition of Countervailing Duties › § 1671a
The agency that handles trade remedies must open a countervailing duty investigation when it finds, from the information it has, that an inquiry is needed or when a qualifying domestic industry files a petition asking for one. A petition must be filed by certain interested domestic parties on behalf of an industry and include the evidence they reasonably have. The petitioner must also 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 must tell the Treasury, and the Treasury has 5 days after the investigation starts to estimate and publish any loss. When a petition is filed, the agency must give a public copy to governments named in the petition and offer consultations to countries that are in the Subsidies Agreement. The agency will not accept outside, unsolicited comments before it decides to start an investigation, and draft petitions submitted for review must be kept confidential. Within 20 days after a petition is filed, the agency must check if the petition has enough evidence and if it really represents the industry. If the agency needs to poll the industry for support, it can take up to 40 days in rare cases. If the product was subject to an order or suspended case in the past 24 months, the agency and the Commission should speed things up. If the petition passes the checks, the agency starts an investigation; if not, it dismisses the petition and explains why. To show industry support, petitioners must represent at least 25% of total domestic production and more than 50% of production among those who took a position. The agency can ignore responses from producers tied to foreign producers or from importers in some cases, and it can poll or sample producers to measure support. The agency tells the Commission its decision right away and shares needed information under protection. If the agency suspects a subsidy breaks international rules, it can ask Customs to collect and send import volume and value data at least once every 30 days until the case is finished or stopped.
