Within 75 days after the date of the preliminary determination under section 1671b(b) of this title, the administering authority shall make a final determination of whether or not a countervailable subsidy is being provided with respect to the subject merchandise; except that when an investigation under this part is initiated simultaneously with an investigation under part II of this subtitle, which involves imports of the same class or kind of merchandise from the same or other countries, the administering authority, if requested by the petitioner, shall extend the date of the final determination under this paragraph to the date of the final determination of the administering authority in such investigation initiated under part II of this subtitle.
If the preliminary determination by the administering authority under section 1671b(b) of this title is negative, and its final determination under subsection (a) is affirmative, then the final determination by the Commission under this subsection shall be made within 75 days after the date of that affirmative final determination.
For purposes of this subsection and section 1671b(d) of this title, the all-others rate shall be an amount equal to the weighted average countervailable subsidy rates established for exporters and producers individually investigated, excluding any zero and de minimis countervailable subsidy rates, and any rates determined entirely under section 1677e of this title.
If the countervailable subsidy rates established for all exporters and producers individually investigated are zero or de minimis rates, or are determined entirely under section 1677e of this title, the administering authority may use any reasonable method to establish an all-others rate for exporters and producers not individually investigated, including averaging the weighted average countervailable subsidy rates determined for the exporters and producers individually investigated.
The administering authority may calculate a single country-wide subsidy rate, applicable to all exporters and producers, if the administering authority limits its examination pursuant to section 1677f–1(e)(2)(B) of this title. The estimated country-wide rate determined under section 1671b(d)(1)(A)(ii) of this title or paragraph (1)(B)(i)(II) of this subsection shall be based on industry-wide data regarding the use of subsidies determined to be countervailable.
Whenever the administering authority or the Commission makes a determination under this section, it shall notify the petitioner, other parties to the investigation, and the other agency of its determination and of the facts and conclusions of law upon which the determination is based, and it shall publish notice of its determination in the Federal Register.
The administering authority shall establish procedures for the correction of ministerial errors in final determinations within a reasonable time after the determinations are issued under this section. Such procedures shall ensure opportunity for interested parties to present their views regarding any such errors. As used in this subsection, the term “ministerial error” includes errors in addition, subtraction, or other arithmetic function, clerical errors resulting from inaccurate copying, duplication, or the like, and any other type of unintentional error which the administering authority considers ministerial.
