Summary

Tells the trade agency how to figure export prices, normal values, dumping margins, and subsidy rates. The agency may use averages and statistically valid samples when there are many sales or many kinds of products. It can ignore price adjustments that are too small to matter. The agency alone chooses the sampling or averaging method, but it should talk with exporters and producers when it can. Normally the agency must find a separate weighted-average dumping margin and a separate countervailable subsidy rate for each known exporter or producer. If there are too many to handle, the agency may examine a reasonable number instead, using either a statistically valid sample or the exporters and producers that account for the largest share of exports. For subsidies, the agency may instead set one countrywide rate that applies to everyone; individual rates it finds are used to set the “all‑others” rate. When checking whether goods are sold in the U.S. at less than fair value, the agency usually compares weighted averages to weighted averages or compares individual sales to individual sales. It may compare a weighted average to individual sales only if export prices clearly vary a lot by buyer, place, or time and the agency explains why the usual methods won’t work. In reviews, when matching an individual U.S. sale to foreign sales, the agency limits the averaging of foreign prices to the calendar month that best matches the U.S. sale. For goods from nonmarket-economy countries, if a countervailable subsidy (not an export subsidy) lowered import prices and the agency can estimate how much that subsidy, together with the chosen normal value method, raised the dumping margin, the agency must lower the antidumping duty by that estimated amount, but not by more than the part of the countervailing duty that is due to that subsidy.

Customs Duties, Source: USLM XML via OLRC

(a)In general
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)Selection of averages and samples
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)Determination of dumping margin (d) Determination of less than fair value
(1)General rule
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)Exception
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.
(e)Determination of countervailable subsidy rate
(1)General rule
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)Exception
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.
The individual countervailable subsidy rates determined under subparagraph (A) shall be used to determine the all-others rate under section 1671d(c)(5) of this title.
(f)Adjustment of antidumping duty in certain proceedings relating to imports from nonmarket economy countries
(1)In general
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,
the administering authority shall, except as provided in paragraph (2), reduce the antidumping duty by the amount of the increase in the weighted average dumping margin estimated by the administering authority under subparagraph (C).
(2)Maximum reduction in antidumping duty
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).
