On August 25, 2016, Enforcement and Compliance, International Trade Administration (ITA), Department of Commerce (Commerce) published in the Federal Register a proposed rule [Docket Number 160815742–6742–01] that would modify the (antidumping) regulations pertaining to the use of constructed value or third country sales for purposes of determining normal value, where the exporting country does not constitute a viable market, and is seeking comments from parties. This modification, if adopted, will specify that, where the exporting country does not constitute a viable market, Commerce normally will calculate normal value based upon constructed value. This modification would invert the preexisting order of preference that, where the exporting country does not constitute a viable market, Commerce normally calculates normal value based on sales in a viable third country. Commerce proposes this modification in light of certain advantages of constructed value over third country sales, such as availability of cost of production information and comparability to U.S. prices. To be assured of consideration, written comments must be received no later than September 26, 2016
