Def.'s Resp. to Pl.'s Rule 56.2 Mot. for J. on the Agency R. and App. ("Def.'s Resp."), ECF No. 39. Defendant-Intervenor Maverick Tube Corporation ("Maverick") opposes Defendant's request for remand and asks that the court rule on the merits of Plaintiff's motion. Confidential Intervenor-Def. Maverick Tube Corp.'s Resp. to Pl. DynaEnergetics U.S., Inc.'s Br. in Supp. of its Rule 56.2 Mot. for J. on the Agency R. ("Def.-Intervenor's Resp."), ECF No. 41. For the reasons set forth below, the court grants the Defendant's request to remand the determination to Commerce for further consideration and explanation.

BACKGROUND

Commerce initiated AD and CVD investigations of certain OCTG from the People's Republic of China ("PRC") on May 5, 2009. Oil Country Tubular Goods from the People's Republic of China, 74 Fed. Reg. 20,671 (Dep't Commerce May 5, 2009) (AD investigation initiation); Certain Oil Country Tubular Goods from the People's Republic of China, 74 Fed. Reg. 20,678 (Dep't Commerce May 5, 2009) (CVD investigation initiation). AD and CVD orders were issued on May 21, 2010 and Jan 20, 2010, respectively. See generally AD & CVD Orders. The scope of the antidumping and countervailing duty orders was defined as:

AD Order, 75 Fed. Reg. at 28,553; see also CVD Order, 75 Fed. Reg. at 3,203-04. The notices also included relevant U.S. Harmonized Tariff Schedule ("HTSUS") subheadings, which Commerce provided for "convenience and customs purposes only" noting that the "written description of the scope of the order is dispositive." AD Order, 75 Fed. Reg. at 28,553; CVD Order, 75 Fed. Reg. at 3,204.

On September 25, 2015, DynaEnergetics requested a scope ruling to determine whether its gun carrier tubing falls outside the scope of the AD and CVD orders. Confidential App. to Pl. DynaEnergetics U.S., Inc.'s Br. in Supp. of its Rule 56.2 Mot. for J. on the Agency R. ("Pl.'s Conf. App."), ECF No. 34, Tab 1 ("Scope Ruling Request"), Confidential Record ("C.R.") 1-7, P.R. 1-6. In its request, Plaintiff explained that "[t]he carrier tubing, which is the outer shell of the gun, is a seamless mechanical tube," id. at 4, and described it as a "customized product made to exact specifications ... which combine a very clean steel chemistry, tight dimensional tolerances and enhanced mechanical characteristics... dedicated for a single end-use: to be incorporated by DynaEnergetics into a perforating gun used to detonate inside oil wells," id. at 2. Plaintiff further explained that "a perforating gun assembly is a single-use device used to perforate existing oil and gas wells in preparation for production using explosive oil charges," and that "[p]erforating tools generally consist of a tube called the carrier which holds the charge holder ..." Id. at 4 (citations omitted).

The Petitioner, Maverick, opposed DynaEnergetics' request, arguing that it is clear from the plain language of the scope that gun carrier tubing is within the scope of the AD & CVD Orders, and that DynaEnergetics' argument rests upon the false premise that gun carrier tubing is mechanical tubing and therefore is excluded from the Orders. Final Scope Ruling at 6-7. After accepting comments from both parties, Commerce issued its scope ruling pursuant to 19 C.F.R. 351.225(k)(1) without initiating a formal scope inquiry. See generally id. In its ruling, Commerce determined that DynaEnergetics' product was within the scope of the AD & CVD orders. See Final Scope Ruling at 10-13.

DynaEnergetics timely commenced this action on March 11, 2016 and filed a motion for judgment on the agency record challenging Commerce's scope determination. See generally Compl.; Pl.'s Mot. In response, Defendant United States requested a remand to "reconsider [Commerce's] findings in light of DynaEnergetics' contentions." Def.'s Resp. at 9. Defendant-Intervenor Maverick opposed Defendant's remand request and asked the court to address Plaintiff's arguments on the merits. Def-Intervenor's Resp. at 31. Plaintiff's motion is fully briefed and the court held a telephonic hearing on the request for a remand on February 1, 2017. Docket Entry, ECF No. 48. For the reasons discussed below, the court will grant Defendant's request for a remand.

JURISDICTION AND STANDARD OF REVIEW

The court has jurisdiction pursuant to § 516A(a)(2)(B)(vi) of the Tariff Act of 1930, as amended, 19 U.S.C. § 1516a(a)(2)(B)(vi) (2012),2 and 28 U.S.C. § 1581(c).

The court will uphold an agency determination that is supported by substantial evidence and otherwise in accordance with law. 19 U.S.C. § 1516a(b)(1)(B)(i).

"Commerce enjoys substantial freedom in conducting [ ] scope inquiries," Eckstrom Indus., Inc. v. United States, 254 F.3d 1068, 1072 (Fed. Cir. 2001) (citation omitted), and is "entitled to substantial deference with regards to its interpretations of its own antidumping duty orders," King's Supply Co., LLC v. United States, 674 F.3d 1343, 1348 (Fed. Cir. 2012). A "scope ruling is a highly fact-intensive and case-specific determination" and "while the plain language of the AD order is paramount, Commerce must also take into account the descriptions of the merchandise contained in the petition, the initial investigation, and the determinations of the Secretary of Commerce (including prior scope determinations) and the Commission." King's Supply Co., 674 F.3d at 1345 (internal quotation marks, citations and alterations omitted); see also 19 C.F.R § 351.225(k)(1). "Since Commerce drafted the antidumping order, the order's meaning and scope are issues particularly within the expertise of that agency. In interpreting its own order, Commerce is performing functions within its special competence." Sandvik Steel Co. v. United States, 164 F.3d 596, 600 (Fed. Cir.1998) (internal quotation marks, citations and alterations omitted). "However, Commerce cannot interpret an antidumping order so as to change the scope of th[e] order, nor can Commerce interpret an order in a manner contrary to its terms." Eckstrom Indus., 254 F.3d at 1072 (internal quotation marks and citation omitted).

DISCUSSION

Plaintiff challenges Commerce's decision that its product is within the scope of the AD & CVD orders as "inconsistent with the evidence on the record describing the product's characteristics and purpose" and Commerce's definition of OCTG as "inconsistent with the scope language and ... based on non-dispositive subheading descriptions of the [HTSUS]." Pl.'s Mot. at 2-3. Plaintiff further argues that Commerce should have initiated a scope inquiry and analyzed the (k)(2) factors because the (k)(1) factors were not dispositive of the scope determination. Id. at 3; see also 19 C.F.R. § 351.225(k)(1), (k)(2).3 Finally, Plaintiff argues that "Commerce's instructions to CBP to continue suspension of liquidation, where such instructions have retroactive effect, were contrary to law." Pl.'s Mot. at 4.

Defendant responds by requesting a remand to fully consider Plaintiff's arguments. Def.'s Resp. at 9. During the telephonic conference with the court, Defendant acknowledged that the agency's analysis was cursory and did not fully address DynaEnergetics' arguments. Defendant asserts this constitutes a substantial and legitimate basis for requesting a remand. Id. at 8-9. Defendant-Intervenor opposes Defendant's request and asks the court to adjudicate Plaintiff's claim on its merits. Def.-Intervenor's Resp. at 29-31.

When an agency determination is challenged in the courts, the agency may "request a remand (without confessing error) in order to reconsider its previous position" and "the reviewing court has discretion over whether to remand." SKF USA Inc. v. United States, 254 F.3d 1022, 1029 (Fed. Cir. 2001) (citations omitted). Remand is appropriate "if the agency's concern is substantial and legitimate," but "may be refused if the agency's request is frivolous or in bad faith." Id.

Commerce's concerns are "substantial and legitimate." Defendant requests a remand so that Commerce may "further consider information from the petition and the determination of the International Trade Commission (ITC) pursuant to 19 C.F.R. § 351.225(k)(1)." Def's Resp. at 1. Defendant acknowledges that "Commerce's further consideration of its findings may affect its existing determination not to conduct an analysis under 19 C.F.R. § 351.225(k)(2) and the CBP instructions issued based on its original determination." Id. at 9. Defendant acknowledges that the agency's reasoning is cursory and that it would be unable to fully respond to Plaintiff's arguments without resorting to post hoc reasoning. Any such post hoc rationalization would be impermissible. Burlington Truck Lines, Inc. v. United States, 371 U.S. 156, 168-69, 83 S.Ct. 239, 9 L.Ed.2d 207 (1962) (the court may not accept "post hoc rationalizations for agency action" and agency action may be "upheld, if at all, on the same basis articulated ... by the agency itself") (citations omitted).

Additionally, during the telephonic conference, Defendant asserted that finality would be furthered by an immediate grant of its request for a remand because it believed the court would not be able to sustain the agency's determination on the insufficient reasoning offered in the original determination. Defendant further acknowledged that the remand determination only would address whether the product in question is within the scope of the orders and issues related to the customs instructions associated with the scope determination, including any retroactivity of those instructions. Plaintiff also asks that any such remand allow Commerce to reconsider the customs instructions associated with the scope determination. Reply Br. of Pl. DynaEnergetics U.S., Inc. ("Pl.'s Reply") at 1-2, 5, ECF No. 45.

Maverick asserts two reasons for opposing Defendant's request for a remand, neither of which are availing. First, Maverick argues that all of Plaintiff's arguments before the court were raised before the agency in the administrative proceeding and, therefore, Commerce had every opportunity to address Plaintiff's arguments. Def-Intervenor's Resp. at 30. While DynaEnergetics may well have raised all of the same arguments before the agency, that is not the same as saying that the agency adequately addressed all of those arguments — which is the point made by Defendant. To the extent the agency failed to address these arguments in its determination, counsel cannot make up for the agency's failings in its briefs to the court as that would constitute impermissible post hoc rationalization. See Burlington Truck Lines, 371 U.S. at 168-69, 83 S.Ct. 239. Particularly in light of the fact intensive nature of scope determinations, it is imperative that the agency supply the reasoning to support its determination in the first instance. See King's Supply Co., 674 F.3d at 1345; Sandvik Steel Co. 164 F.3d at 600.

Maverick also argues that concerns for finality should weigh against granting the request for a remand, particularly when Defendant has not indicated what error occurred. Def-Intervenor's Resp. at 29-30 (citing Maverick Tube Corp. v. United States, 39 CIT ___, ___, 107 F.Supp.3d 1318, 1334-35 (2015), and Corus Staal BV v. United States, 27 C.I.T. 388, 391, 259 F.Supp.2d 1253 (2003)). In this case, the error acknowledged by Defendant was the failure to fully address the arguments made by DynaEnergetics to the agency. Unlike the cases cited by Defendant-Intervenor, Defendant does not seek a remand to reconsider or change a statutory interpretation or application of policy. See Def.'s Resp. at 8-9. Instead, it seeks to perform the very function it should have performed during the original administrative proceeding — providing a reasoned determination taking into account the facts and arguments before it. Id. Such a remand request should only be denied if the request is frivolous or in bad faith, SKF USA Inc., 254 F.3d at 1029, and that is not the case here.

For the reasons stated above, the court grants Defendant's request for a remand to reconsider the scope determination at issue along with, if appropriate, the customs instructions associated with the scope determination.
