A countervailing duty investigation shall be initiated whenever the administering authority determines, from information available to it, that a formal investigation is warranted into the question of whether the elements necessary for the imposition of a duty under section 1671(a) of this title exist.
A countervailing duty proceeding shall be initiated whenever an interested party described in subparagraph (C), (D), (E), (F), or (G) of section 1677(9) of this title files a petition with the administering authority, on behalf of an industry, which alleges the elements necessary for the imposition of the duty imposed by section 1671(a) of this title, and which is accompanied by information reasonably available to the petitioner supporting those allegations. The petition may be amended at such time, and upon such conditions, as the administering authority and the Commission may permit.
If the sole basis of a petition filed under paragraph (1) is the derogation of an international undertaking on official export credits, the Administering Authority shall immediately notify the Secretary of the Treasury who shall, in consultation with the Administering Authority, within 5 days after the date on which the administering authority initiates an investigation under subsection (c), determine the existence and estimated value of the derogation, if any, and shall publish such determination in the Federal Register.
The administering authority shall not accept any unsolicited oral or written communication from any person other than an interested party described in section 1677(9)(C), (D), (E), (F), or (G) of this title before the administering authority makes its decision whether to initiate an investigation, except as provided in subparagraph (A)(ii) and subsection (c)(4)(D), and except for inquiries regarding the status of the administering authority’s consideration of the petition.
In determining industry support under subparagraph (A), the administering authority shall disregard the position of domestic producers who oppose the petition, if such producers are related to foreign producers, as defined in section 1677(4)(B)(ii) of this title, unless such domestic producers demonstrate that their interests as domestic producers would be adversely affected by the imposition of a countervailing duty order.
Before the administering authority makes a determination with respect to initiating an investigation, any person who would qualify as an interested party under section 1677(9) of this title if an investigation were initiated, may submit comments or information on the issue of industry support. After the administering authority makes a determination with respect to initiating an investigation, the determination regarding industry support shall not be reconsidered.
For purposes of this subsection, the term “domestic producers or workers” means those interested parties who are eligible to file a petition under subsection (b)(1).
If, at any time after the initiation of an investigation under this part, the administering authority finds a reasonable basis to suspect that the alleged countervailable subsidy is inconsistent with the Subsidies Agreement, the administering authority may request the Commissioner of U.S. Customs and Border Protection to compile information on an expedited basis regarding entries of the subject merchandise. Upon receiving such request, the Commissioner of U.S. Customs and Border Protection shall collect information regarding the volume and value of entries of the subject merchandise and shall transmit such information to the administering authority at such times as the administering authority shall direct (at least once every 30 days), until a final determination is made under section 1671d(a) of this title, the investigation is terminated, or the administering authority withdraws the request.
