If during the period of monitoring referred to in subparagraph (A), the administering authority determines that there is sufficient information to initiate a formal investigation under this subsection regarding an additional supplier country, the administering authority shall immediately initiate such an investigation.
An antidumping 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 1673 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.
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 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 an antidumping 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).
