Stupp Corp. v. United States, No. 20-1857 (Fed. Cir. 2021)Annotate this Case
The Department of Commerce initiated a less-than-fair-value investigation into the importation of welded line pipe from Korea, focused on sales by two Korea-based respondents, SeAH and HYSCO. Commerce issued a preliminary determination that SeAH likely was selling welded line pipe in the U.S. at less than fair value during the relevant period. SeAH filed a case brief challenging Commerce’s statistical analysis and citing academic literature in support of that challenge. Commerce rejected SeAH’s case brief for violating procedural regulations and issued a final determination. Commerce calculated SeAH’s weighted-average dumping margin to be above the de minimis threshold for less-than-fair-value investigations by applying its differential pricing analysis to SeAH’s sales and selecting the hybrid approach for calculating SeAH’s weighted-average dumping margin. The Trade Court affirmed.
The Federal Circuit affirmed in part, upholding Commerce’s rejection of portions of SeAH’s case brief and aspects of the analysis Commerce used to derive the dumping margin. The court vacated and remanded to give Commerce an opportunity to explain whether the limits on the use of the Cohen’s d test to evaluate whether the test group differs significantly from the comparison group were satisfied or whether those limits need not be observed when Commerce uses the test in less-than-fair-value adjudications. The court “invited” Commerce to clarify its argument that having the entire universe of data rather than a sample makes it permissible to disregard the otherwise-applicable limitations on the use of the Cohen’s d test.
