Summary

The agency in charge of antidumping and countervailing cases may use averages and statistically valid samples when there are a lot of sales or many kinds of products. It can ignore tiny price adjustments that do not matter. The agency alone decides how to pick samples, but it must try to talk with exporters and producers about the method when it can. When possible, the agency must figure out an individual dumping margin and an individual subsidy rate for each known exporter or producer. If there are too many, it may check a statistically valid sample or focus on the exporters and producers that make up the largest share of shipments it can reasonably examine. It may also set one country-wide rate for everyone if needed. In investigations, the agency normally compares weighted-average home prices to weighted-average export prices or compares individual home sales to individual export sales. It may compare average home prices to individual export sales when export prices vary a lot by buyer, place, or time and it explains why. In reviews, when matching an individual export sale to average home prices, the averages must be limited to the calendar month that best matches the export sale. For nonmarket-economy goods where home value is constructed, if a non-export government subsidy lowered import prices and the agency can estimate how that raised the dumping margin, the agency may reduce the antidumping duty but not by more than the part of the countervailing duty tied to that subsidy. Key terms: export price (what the seller charges abroad), normal value (home-market or constructed price), dumping margin (how much lower the export price is), countervailable subsidy rate (duty to offset a government subsidy).

Customs Duties — Source: USLM XML via OLRC

(a)For purposes of determining the export price (or constructed export price) under section 1677a of this title or the normal value under section 1677b of this title, and in carrying out reviews under section 1675 of this title, the administering authority may—
(1)use averaging and statistically valid samples, if there is a significant volume of sales of the subject merchandise or a significant number or types of products, and
(2)decline to take into account adjustments which are insignificant in relation to the price or value of the merchandise.
(b)The authority to select averages and statistically valid samples shall rest exclusively with the administering authority. The administering authority shall, to the greatest extent possible, consult with the exporters and producers regarding the method to be used to select exporters, producers, or types of products under this section.
(c)(1)In determining weighted average dumping margins under section 1673b(d), 1673d(c), or 1675(a) of this title, the administering authority shall determine the individual weighted average dumping margin for each known exporter and producer of the subject merchandise.
(2)If it is not practicable to make individual weighted average dumping margin determinations under paragraph (1) because of the large number of exporters or producers involved in the investigation or review, the administering authority may determine the weighted average dumping margins for a reasonable number of exporters or producers by limiting its examination to—
(A)a sample of exporters, producers, or types of products that is statistically valid based on the information available to the administering authority at the time of selection, or
(B)exporters and producers accounting for the largest volume of the subject merchandise from the exporting country that can be reasonably examined.
(d)(1)(A)In an investigation under part II of this subtitle, the administering authority shall determine whether the subject merchandise is being sold in the United States at less than fair value—
(i)by comparing the weighted average of the normal values to the weighted average of the export prices (and constructed export prices) for comparable merchandise, or
(ii)by comparing the normal values of individual transactions to the export prices (or constructed export prices) of individual transactions for comparable merchandise.
(B)The administering authority may determine whether the subject merchandise is being sold in the United States at less than fair value by comparing the weighted average of the normal values to the export prices (or constructed export prices) of individual transactions for comparable merchandise, if—
(i)there is a pattern of export prices (or constructed export prices) for comparable merchandise that differ significantly among purchasers, regions, or periods of time, and
(ii)the administering authority explains why such differences cannot be taken into account using a method described in paragraph (1)(A)(i) or (ii).
(2)In a review under section 1675 of this title, when comparing export prices (or constructed export prices) of individual transactions to the weighted average price of sales of the foreign like product, the administering authority shall limit its averaging of prices to a period not exceeding the calendar month that corresponds most closely to the calendar month of the individual export sale.
(e)(1)In determining countervailable subsidy rates under section 1671b(d), 1671d(c), or 1675(a) of this title, the administering authority shall determine an individual countervailable subsidy rate for each known exporter or producer of the subject merchandise.
(2)If the administering authority determines that it is not practicable to determine individual countervailable subsidy rates under paragraph (1) because of the large number of exporters or producers involved in the investigation or review, the administering authority may—
(A)determine individual countervailable subsidy rates for a reasonable number of exporters or producers by limiting its examination to—
(i)a sample of exporters or producers that the administering authority determines is statistically valid based on the information available to the administering authority at the time of selection, or
(ii)exporters and producers accounting for the largest volume of the subject merchandise from the exporting country that the administering authority determines can be reasonably examined; or
(B)determine a single country-wide subsidy rate to be applied to all exporters and producers.
(f)(1)If the administering authority determines, with respect to a class or kind of merchandise from a nonmarket economy country for which an antidumping duty is determined using normal value pursuant to section 1677b(c) of this title, that—
(A)pursuant to section 1671(a)(1) of this title, a countervailable subsidy (other than an export subsidy referred to in section 1677a(c)(1)(C) of this title) has been provided with respect to the class or kind of merchandise,
(B)such countervailable subsidy has been demonstrated to have reduced the average price of imports of the class or kind of merchandise during the relevant period, and
(C)the administering authority can reasonably estimate the extent to which the countervailable subsidy referred to in subparagraph (B), in combination with the use of normal value determined pursuant to section 1677b(c) of this title, has increased the weighted average dumping margin for the class or kind of merchandise,
(2)The administering authority may not reduce the antidumping duty applicable to a class or kind of merchandise from a nonmarket economy country under this subsection by more than the portion of the countervailing duty rate attributable to a countervailable subsidy that is provided with respect to the class or kind of merchandise and that meets the conditions described in subparagraphs (A), (B), and (C) of paragraph (1).
