*1345Can an electronic transmission -- or only snail mail -- qualify as a "mailing?" Do certain pallet products fall within the plain meaning of the scope of an order seeking to effectuate fair trade for domestic producers and industry? This case involves these jurisdictional and scope interpretation issues. Plaintiff Perfectus Aluminum, Inc., ("Perfectus") is an importer and distributor of aluminum extrusions. Defendant-Intervenor Aluminum Extrusions Fair Trade Committee ("AEFTC") is a trade association of domestic producers of aluminum extrusions that requested a scope ruling finding that Perfectus's pallet products composed of aluminum extrusions are subject to the antidumping and countervailing duty orders on aluminum extrusions from the People's Republic of China. Aluminum Extrusions from the People's Republic of China: Antidumping Duty Order, 76 Fed. Reg. 30,650 (Dep't Commerce May 26, 2011) ("Antidumping Duty Order"); Aluminum Extrusions from the People's Republic of China: Countervailing Duty Order, 76 Fed. Reg. 30,653 (Dep't Commerce May 26, 2011) ("Countervailing Duty Order") (collectively, the "Orders"). The United States Department of Commerce ("Commerce") found that Perfectus's merchandise is within the plain language of the scope of the Orders and instructed United States Customs and Border Protection ("Customs") to continue to suspend liquidation of entries back to the date of the first suspension of Perfectus's merchandise. Perfectus appeals Commerce's determination. AEFTC counters that this appeal is untimely because it was commenced more than thirty days after notification of the final scope ruling through email notification, that the case should be dismissed for lack of jurisdiction, and that, in any event, Commerce did not err in its scope ruling. The court (1) concludes that jurisdiction over this action exists because Perfectus's complaint seeking review of the scope ruling was filed within thirty days of the mailing by post of that ruling as required by statute and was therefore timely, and (2) sustains Commerce's finding that the pallet products fall within the plain language of the scope of the Orders.
BACKGROUND
I. Legal and Regulatory Framework of Scope Reviews Generally
Dumping occurs when a foreign company sells a product in the United States for less than fair value -- that is, for a lower price than in its home market. Sioux Honey Ass'n v. Hartford Fire Ins. Co., 672 F.3d 1041, 1046 (Fed. Cir. 2012) ). Similarly, a foreign country may provide a countervailable subsidy to a product and thus artificially lower its price. U.S. Steel Grp. v. United States, 96 F.3d 1352, 1355 n.1 (Fed. Cir. 1996). To empower Commerce to offset economic distortions caused by dumping and countervailable subsidies, Congress enacted the Tariff Act of 1930.1
*1346Sioux Honey Ass'n, 672 F.3d at 1046-47. Under the Tariff Act's framework, Commerce may -- either upon petition by a domestic producer or of its own initiative -- begin an investigation into potential dumping or subsidies and, if appropriate, issue orders imposing duties on the subject merchandise. Id.
Because the description of products contained in the scope of an antidumping or countervailing duty order must be written in general terms to encompass the full range of subject merchandise, issues may arise as to whether a particular product is included within the scope of the order. See 19 C.F.R. § 351.225(a). To provide producers and importers with notice as to whether their products fall within the scope of an antidumping or countervailing duty order, Congress authorized Commerce to issue scope rulings clarifying "whether a particular type of merchandise is within the class or kind of merchandise described in an existing ... order." 19 U.S.C. § 1516a(a)(2)(B)(vi). As "no specific statutory provision govern[s] the interpretation of the scope of antidumping or countervailing orders," Commerce and the courts developed a three-step analysis. Shenyang Yuanda Aluminum Indus. Eng'g Co. v. United States, 776 F.3d 1351, 1354 (Fed. Cir. 2015) ; Polites v. United States, 35 C.I.T. 312, 313-14, 755 F. Supp. 2d 1352, 1354 (2011) ; 19 C.F.R. § 351.225(k).
Because "[t]he language of the order determines the scope of an antidumping duty order[,]" any scope ruling begins with an examination of the language of the order at issue. Tak Fat Trading Co. v. United States, 396 F.3d 1378, 1382 (Fed. Cir. 2005) (citing Duferco Steel, Inc. v. United States, 296 F.3d 1087, 1097 (Fed. Cir. 2002) ). If the terms of the order are unambiguous, then those terms govern. Id. at 1382-83. "[T]he question of whether the unambiguous terms of a scope control the inquiry, or whether some ambiguity exists is a question of law that we review de novo." Meridian Prod., LLC v. United States, 851 F.3d 1375, 1382 (Fed. Cir. 2017). "Although the scope of a final order may be clarified, it can not be changed in a way contrary to its terms." Duferco, 296 F.3d at 1097 (quoting Smith Corona Corp. v. United States, 915 F.2d 683, 686 (Fed. Cir. 1990) ). For that reason, "if [the scope of an order] is not ambiguous, the plain meaning of the language governs." ArcelorMittal Stainless Belg. N.V. v. United States, 694 F.3d 82, 87 (Fed. Cir. 2012).
"In determining the common meaning of a term, courts may and do consult dictionaries, scientific authorities, and other reliable sources of information, including testimony of record." NEC Corp. v. Dep't of Commerce, 23 C.I.T. 727, 731, 74 F. Supp. 2d 1302, 1307 (1999) (quoting Holford USA Ltd. v. United States, 19 C.I.T. 1486, 1493-94, 912 F. Supp. 555, 561 (1995) ). Furthermore, "[b]ecause the primary purpose of an antidumping order is to place foreign exporters on notice of what merchandise is subject to duties, the terms of an order should be consistent, to the extent possible, with trade usage." ArcelorMittal, 694 F.3d at 88.
If Commerce determines that the terms of the order are either ambiguous or reasonably subject to interpretation, then Commerce "will take into account ... the descriptions of the merchandise contained in the petition, the initial investigation, and [prior] determinations [of Commerce] (including prior scope determinations) and the [International Trade] Commission." 19 C.F.R. § 351.225(k)(1) ("(k)(1) sources"); Polites, 755 F. Supp. 2d at 1354 ; Meridian, 851 F.3d at 1382. To be dispositive, the *1347(k)(1) sources "must be 'controlling' of the scope inquiry in the sense that they definitively answer the scope question." Polites, 755 F. Supp. 2d at 1354 (quoting Sango Int'l v. United States, 484 F.3d 1371, 1379 (Fed. Cir. 2007) ). If Commerce "can determine, based solely upon the application and the descriptions of the merchandise referred to in paragraph (k)(1) of ... section [351.225], whether a product is included within the scope of an order ... [Commerce] will issue a final ruling[.]" 19 C.F.R. § 351.225(d).
If a § 351.225(k)(1) analysis is not dispositive, Commerce will initiate a scope inquiry under § 351.225(e) and apply the five criteria from Diversified Prods. Corp. v. United States, 6 C.I.T. 155, 162, 572 F. Supp. 883, 889 (1983) as codified in 19 C.F.R. § 351.225(k)(2).2
II. Factual and Procedural History of the Orders
On May 26, 2011, after the International Trade Commission had determined that imports of certain aluminum extrusions were materially injuring United States industry, Commerce issued antidumping and countervailing duty orders covering 1xxx, 3xxx, and 6xxx aluminum extrusions from China. Orders. The scope of the Orders reads, in relevant part:
The merchandise covered by the order is aluminum extrusions which are shapes and forms, produced by an extrusion process, made from aluminum alloys having metallic elements corresponding to the alloy series designations published by The Aluminum Association commencing with the numbers 1, 3, and 6 ...
The scope ... excludes finished merchandise containing aluminum extrusions as parts that are fully and permanently assembled and completed at the time of entry, such as finished windows with glass, doors with glass or vinyl, picture frames with glass pane and backing material, and solar panels.
Antidumping Duty Order, 78 Fed. Reg. at 30,650-51.3
III. Factual and Procedural History of this Case
On March 3, 2017, AEFTC filed a request with Commerce to determine that certain 6xxx aluminum extrusions from China are within the scope of the Orders. Petitioner's Scope Ruling Request for 6xxx Series Aluminum Pallets (Mar. 3, 2017), Public Record ("P.R.") 1-7, Confidential Record ("C.R.") 1-7 ("6xxx Scope Ruling Request"). In the 6xxx Scope Ruling Request, AEFTC described the merchandise at issue as follows: "extruded profiles made of series 6xxx aluminum alloy cut-to-length and welded in the shape of pallets ... regardless of producer or exporter." Id. at 5.
Commerce issued the requested scope ruling on June 13, 2017, finding that the merchandise at issue is subject to the Orders. Antidumping and Countervailing Duty Orders on Aluminum Extrusions from the People's Republic of China: Final Scope Ruling on Certain Aluminum Pallets (June 13, 2017), P.R. 28 ("6xxx Final Scope Ruling"). Specifically, Commerce found that the merchandise at issue is within the *1348plain language of the scope of the Orders, the finished merchandise exclusion does not apply here, and the merchandise at issue is in existence. Id. at 13, 15. Commerce further instructed Customs to continue to suspend liquidation of entries back to the merchandise at issue's date of first suspension. Id. at 15. On March 27, 2018, upon realizing that it had not previously done so, Commerce mailed the notice of the 6xxx Final Scope Ruling.4 See Memorandum re: Antidumping and Countervailing Duty Orders on Aluminum Extrusions from the People's Republic of China: March 27, 2018 Mailing of Final Scope Ruling on Certain Aluminum Pallets, (June 4, 2017), P.R 34 ("Proof of Mailing"). Within thirty days of that mailing, Perfectus filed a summons and complaint with this court. Summ., Apr. 23, 2018, ECF No. 1; Compl., Apr. 25, 2018, ECF No. 9.
On August 3, 2018, AEFTC moved to dismiss this case on the grounds that Perfectus's complaint was untimely. Def.-Inter.'s Mot. to Dis., ECF No. 25 ("Def.-Inter.'s MTD Br."). Perfectus and the Government both filed briefs opposing AEFTC's motion on August 28, 2018. Pl.'s Resp. to Mot. to Dis., ECF No. 28 ("Pl.'s Resp. to MTD"); Def.'s Resp. to Mot. to Dis., ECF No. 26 ("Def.'s Resp. to MTD").

On October 30, 2018, Perfectus moved for judgment on the agency record pursuant to Rule 56.2 of this court. Pl.'s Mot. for J. on the Agency Record, ECF No. 34. Earlier, on August 28, 2018, Perfectus had filed its brief in support of a motion for judgment on the agency record. Pl.'s 56.2 Br., ECF No. 27.

DISCUSSION
I. Motion to Dismiss
Subject matter jurisdiction constitutes a threshold inquiry. See Steel Co. v. Citizens for a Better Env't, 523 U.S. 83, 94, 118 S.Ct. 1003, 140 L.Ed.2d 210 (1998). Where subject matter jurisdiction is challenged pursuant to USCIT Rule 12(b)(1), "the burden rests on plaintiff to prove that jurisdiction exists." Lowa, Ltd. v. United States, 561 F. Supp. 441, 443 (1983), aff'd, 724 F.2d 121 (Fed. Cir. 1984) (quoted in Pentax Corp. v. Robison, 125 F.3d 1457, 1462 (Fed. Cir. 1997), modified in part, 135 F.3d 760 (Fed. Cir. 1998) ). Here, AEFTC filed a motion to dismiss, alleging that Perfectus failed to timely commence this action as required by the jurisdictional requirements set forth in 19 U.S.C. § 1516a(a)(2)(A), and that as a result, the court lacks subject matter jurisdiction over Perfectus's complaint pursuant to USCIT Rule 12(b)(1). See Def.-Inter.'s MTD at 1.
Perfectus, as plaintiff, contends that there is subject matter jurisdiction. The defendant, the Government -- though urging that on the merits plaintiff's motion for judgment on the agency record should fail -- at the same time supports Perfectus's contention that the complaint was timely filed and that this court has jurisdiction.
Perfectus filed this action asserting jurisdiction under 28 U.S.C. § 1581(c). Compl. ¶ 3; First Amended Compl. ¶ 3, May 2, 2018, ECF No. 12. 28 U.S.C. § 1581(c) confers on this court "exclusive jurisdiction of any civil action commenced under section 516A ... of the Tariff Act of 1930," as amended (the "Act"). 28 U.S.C. § 1581(c). The Act was amended to include the provisions on judicial review through the Trade Agreements Act of 1979. H. Rep. No. 96-317 at 179-82 (1979); S. Rep. 96-249 at 27-28 (1979). Section 516A of the Act, codified at 19 U.S.C. § 1516a, enumerates eight different determinations in antidumping and countervailing duty proceedings subject to judicial review. Through the Trade and Tariff Act of 1984, Congress added the provision to 19 U.S.C. § 1516a specifically identifying scope rulings as reviewable determinations and providing the deadline to appeal such determinations. See 19 U.S.C. § 1516a(a)(2)(B)(vi) (making reviewable "[a] determination by the administering authority as to whether a particular type of merchandise is within the class or kind of merchandise described in an existing finding of dumping or antidumping or countervailing duty order"); H. Rep. No. 98-1156, at 91 (1984) (Conf. Rep).
The statute distinguished between those determinations for which the deadline for filing an appeal would be based on the date of publication of the applicable determination in the Federal Register and those determinations for which the deadline for filing an appeal would be based on the date of mailing of a determination. Section 1516a(a)(2) provides that, "in general," judicial review of determinations on the record must be commenced within thirty days after "the date of publication in the Federal Register." 19 U.S.C. § 1516a(a)(2)(A)(i). However, judicial review of a determination described in clause (vi) of subparagraph (B) -- such as the 6xxx Final Scope Ruling currently before the court -- must be commenced thirty days after "the date of mailing of a determination." 19 U.S.C. § 1516a(a)(2)(A)(ii).6 This distinction was *1350necessary for scope determinations by Commerce because they, unlike the other determinations identified in the statute, were not published in the Federal Register.7 When these provisions were added to the statute, in 1984, email or electronic notification of Commerce's determinations was not possible. Thus, for a determination that would not be published in the Federal Register, the only way to notify interested parties of a final ruling was by post.
Section 1516a(a)(2)(A)(ii) does not define "mailing." With respect to review of a scope determination, Commerce has interpreted "mailing" to mean the transmission of materials by mail or courier as understood in common parlance -- for example, via the United States Postal Service -- and as was understood in 1984 when the statute was enacted. Here, Commerce issued a final scope ruling concerning the merchandise at issue on June 13, 2017, and subsequently mailed that final scope ruling to Perfectus on March 27, 2018. Proof of Mailing. Perfectus commenced this action within thirty days of that mailing: on April 23, 2018, Perfectus filed a summons with this court. Summ. Perfectus (joined by the Government) thus asserts that it commenced its action within the requisite thirty days and that this court therefore has jurisdiction.
AEFTC, however, argues that Perfectus did not timely commence this action. AEFTC notes that Commerce notified the parties of the final scope ruling through an email notification produced by the Antidumping and Countervailing Duty Centralized Electronic Service System ("ACCESS")8 on June 14, 2017. Def-Inter.'s MTD Br. at Ex. 3. According to AEFTC, this email notification constitutes a "mailing," and thus Perfectus's commencement of this action on April 23, 2018 was outside the statutory window and untimely. AEFTC asserts that "the Court should interpret 'mailing' within the meaning of 19 U.S.C. § 1516a(a)(2)(A) to include electronic mail notifications" because "[t]he term mail in the statute does not expressly limit itself to only hand mailing." Id. at 7.
The court does not consider AEFTC's argument persuasive. "Since section 1516a(a)(2)(A) specifies the terms and conditions upon which the United *1351States has waived its sovereign immunity in consenting to be sued in the Court of International Trade, those limitations must be strictly observed and are not subject to implied exceptions." Georgetown Steel Corp. v. United States, 801 F.2d 1308, 1312 (Fed. Cir. 1986) (citing Lehman v. Nakshian, 453 U.S. 156, 161, 101 S.Ct. 2698, 69 L.Ed.2d 548 (1981) ); see also Orlando Food Corp. v. United States, 423 F.3d 1318, 1320 (Fed. Cir. 2005) ("Courts are not free to infer waivers of sovereign immunity.") (citing Library of Cong. v. Shaw, 478 U.S. 310, 318, 106 S.Ct. 2957, 92 L.Ed.2d 250 (1986) ). Where a waiver of sovereign immunity is at issue, the language of the statute must be strictly construed, and any ambiguities resolved in favor of immunity. See Orlando Food, 423 F.3d at 1320 (noting that "any express waivers must be narrowly construed") (citing Library of Cong., 478 U.S. at 318, 106 S.Ct. 2957 ); United States v. Williams, 514 U.S. 527, 531, 115 S.Ct. 1611, 131 L.Ed.2d 608 (1995) (stating that, in resolving questions about the waiver of sovereign immunity, "we may not enlarge the waiver beyond the purview of the statutory language"). Here, a strict construction limits the definition of "mailing" to a physical, hand-mailing -- extant in 1984 when the legislation was enacted -- as opposed to an electronic missive (not then available). AEFTC has not presented any authority suggesting that Congress intended the "date of mailing" to include transmission by electronic means, nor has the court found such authority.
The court's conclusion is consistent with this court's prior, persuasive cases addressing whether electronic forms of communication constitute "mailing." In Bond Street, Ltd. v. United States, where plaintiff commenced the action for review after fax notification but there was no mailing of the final scope ruling, this court held that a fax did not satisfy the statutory mailing requirement and dismissed the matter, without prejudice, for want of jurisdiction. 31 C.I.T. 1691, 1695, 521 F. Supp. 2d. 1377, 1381-82 (2007) (citing Georgetown Steel, 801 F.2d at 1312 ). Similarly, in Medline Indus. v. United States, where plaintiff commenced the action after email notification but before the mailing of the final scope ruling, this court held that an "email message" did not satisfy the statutory "mailing" requirement and disposed of the matter in the same fashion as the Bond Street court. 37 CIT ----, ----, 911 F. Supp. 2d 1358, 1361-62 (2013).9
AEFTC contends that Bond Street and Medline are distinguishable because the plaintiffs in Bond Street and Medline did not wait "an unreasonable amount of time" prior to filing. Perfectus's diligence is not relevant here because (i) the statute does not contain a diligence requirement and (ii) Perfectus filed within thirty days of Commerce's physical mailing. Even if the statute contained a diligence requirement, Perfectus notified Commerce in August 2017 that it had yet to receive a physical mailing of the final scope ruling. Additionally, Perfectus even threatened litigation to compel the mailing. See supra, n.4.
AEFTC also argues that Bond Street and Medline are distinguishable because the underlying proceedings pre-date ACCESS's *1352use in antidumping and countervailing duty proceedings, and that an ACCESS notification constructively satisfies the "mailing" requirement. General widespread use of email and fax technology pre-dates both Bond Street and Medline, yet the court in those cases declined to expand the statutory definition out of concern for impermissibly enlarging the waiver of sovereign immunity contained in section 1516a(a)(2)(A). See, e.g., Medline, 911 F. Supp. 2d at 1361 ("Although email is a widespread means of communication, Medline has not demonstrated that an email is sufficient to commence the filing period under section 1516a(a)(2)(A)(ii)."). Therefore, Bond Street and Medline are not distinguishable from the case here and are persuasive.
AEFTC also draws attention to Perfectus's concession of actual notice of the final scope ruling as of June 14, 2017. Def.-Inter.'s MTD Reply at 10. However, the statute does not reference actual notice when setting the filing deadline; it only refers to the date of mailing. 19 U.S.C. § 1516a(a)(2)(A)(ii). Therefore, the court finds this argument unpersuasive.10
In short, AEFTC's assertion that a notification generated by ACCESS triggers the clock11 for judicial review is unsupported.12 This case was brought within thirty days after the date of mailing of Commerce's determination. Commerce mailed the 6xxx Final Scope Ruling on March 27, 2018. Proof of Mailing. Perfectus commenced this case on April 23, 2018, 27 days after the date on which Commerce mailed the scope ruling. The court concludes that Perfectus's complaint was timely and denies AEFTC's motion to dismiss. The court has jurisdiction pursuant to 28 U.S.C. § 1581(c) and 19 U.S.C. § 1516a(a)(2)(B)(vi).
II. Motion for Judgment on the Agency Record
The standard of review in this action is set forth in 19 U.S.C. § 1516a(b)(1)(B)(i) : "[t]he court shall hold unlawful any determination, finding, or conclusion found ... to be unsupported by substantial evidence on the record, or otherwise not in accordance *1353with law." According to Perfectus, its merchandise is not within the scope of the Orders because it qualifies for the finished merchandise exclusion. Perfectus further argues that Commerce's issuance of a scope ruling here was improper because it did not initiate a formal scope inquiry and that the record does not indicate the merchandise at issue was being produced or imported at the time the scope ruling was issued. Perfectus also contends that Commerce should not have instructed Customs to retroactively suspend liquidation because liquidation of the merchandise at issue was never suspended in the first place. For the reasons described below, the court denies Perfectus's motion for judgment on the agency record.
A. The Merchandise at Issue Fits Within the Plain Language of the Scope of the Orders and Does Not Qualify for Any Exclusions.
According to the Government, the finished merchandise exclusion does not apply to the merchandise at issue for two reasons: first, the merchandise at issue consists entirely of aluminum extrusions, and, second, the merchandise at issue is not suitable for use as a pallet and is thus not a finished product. Perfectus contends that both these bases are incorrect.13
The relevant scope language includes "aluminum extrusions which are shapes and forms, produced by an extrusion process, made from aluminum alloys having metallic elements corresponding to the alloy series designations published by the Aluminum Association commencing with the numbers 1, 3, and 6." Antidumping Duty Order, 76 Fed. Reg. at 30,650. Further, "[a]luminum extrusions are produced and imported in a wide variety of shapes and forms, ... [and] may also be fabricated, i.e., prepared for assembly[,] ... [which] include[s], but [is] not limited to, extrusions that are cut-to-length." Id. "Subject extrusions may be identified with reference to their end use .... Such goods are subject merchandise if they otherwise meet the scope definition, regardless of whether they are ready for use at the time of importation." Id. at 30,651. The relevant language excludes from the scope "finished merchandise containing aluminum extrusions as parts that are fully and permanently assembled and completed at the time of entry, such as finished windows with glass, doors with glass or vinyl, picture frames with glass pane and backing material, and solar panels." Id. (emphasis added). The merchandise at issue consists of "certain aluminum extrusions from [China] made of series 6xxx aluminum alloy which are cut-to-length and welded together in the form of a pallet, regardless of producer or exporter." 6xxx Final Scope Ruling at 1.
The court concludes that Commerce's determination that the pallets are within the scope of the Orders and do not qualify for the finished merchandise exclusion because they exist entirely of aluminum extrusions and contain no other materials "as parts" is in accordance with law.14 First, an alternative interpretation would result in reading out the "as parts" term from the relevant scope language. Second, the plural construction of "as parts" requires the finished merchandise exclusion to cover *1354products consisting of both aluminum extrusions and non-extruded aluminum parts; an alternative interpretation would, as Commerce noted in its 6xxx Final Scope Ruling, allow the finished merchandise exclusion to "swallow the rule embodied by the scope." Third, the examples given in the finished merchandise exclusion's text contain both an aluminum extrusion and a non-aluminum component. Thus, in light of the plain language of the Orders, the court concludes that Commerce did not err by concluding that the meaning of "as parts" in the context of the finished merchandise exclusion requires both aluminum extrusion and non-aluminum extrusion components.
In Perfectus's view, this interpretation is incorrect because the Federal Circuit's opinion in Whirlpool Corp. v. United States, 890 F.3d 1302 (Fed. Cir. 2018), "made it clear that Commerce erred in interpreting the Orders to require goods qualifying for the finished merchandise exclusion to also have non-extruded aluminum components." Pl.'s 56.2 Br. at 14. However, the Federal Circuit made no such pronouncement in Whirlpool. In that case, the product at issue was finished merchandise containing aluminum extrusions and non-aluminum extrusions; the Federal Circuit addressed whether an exception for fasteners to the finished good kits exclusion applied to the finished merchandise exclusion as well. The fastener exception states that "[a]n imported product will not be considered a 'finished goods kit' and therefore excluded from the scope of the investigation merely by including fasteners such as screws, bolts, etc. in the packaging with an aluminum extrusion product." Whirlpool, 890 F.3d at 1306 (quoting Meridian, 851 F.3d at 1385 ). The Federal Circuit held that, based on the plain language of the fastener exception, the fastener exception applied only to the finished good kits exclusion from the scope order and remanded to Commerce on that basis. Id. at 1310-11. The Federal Circuit did not decide whether the products at issue in that case "me[t] the requirements for the finished merchandise exclusion." Id. at 1311. Nor did the Federal Circuit determine that a product composed entirely of aluminum extrusions -- unlike the product at issue in Whirlpool, which contained non-aluminum extrusion parts -- would be eligible for the finished merchandise exclusion. Perfectus's argument is therefore inapposite.
Moreover, Meridian, 851 F.3d 1375, supports Commerce's interpretation. In Meridian, the Federal Circuit, in interpreting the separate "finished goods kit" exclusion of the Orders at issue here, noted that "[a]lthough not necessary to our analysis ... [t]he plain text of the other passages in the Orders thus contemplates a basic divide between products whose components relevant to the scope inquiry consist of non-aluminum extrusion parts, which are excluded from the scope of the Orders, and products whose components relevant to the scope inquiry contain only aluminum extrusion parts, which are not excluded." Meridian, 851 F.3d at 1384.
Perfectus argues that the relevant language in Meridian concerns the finished goods kit exclusion, not the finished merchandise exclusion, and is thus inapposite.15 Pl.'s Reply to 56.2 Mot. at 11 n.13.
*1355However, the issue in Meridian and the issue here are meaningfully similar. Meridian's analytical approach to the text of the Orders -- the contemplation of a "basic divide" between merchandise containing only aluminum extrusions and merchandise with non-aluminum extrusion components -- easily applies to the finished merchandise exclusion.
Perfectus also takes issue with Commerce's reliance on the fact that the listed examples in the exclusion's text are unlike the products at issue. Perfectus casts a wide net in search of authority supporting the proposition that lists need not be exhaustive, Pl.'s Reply to 56.2 Mot. at 11 n.11, but fails to persuade the court that Commerce's interpretation was incorrect.
As Commerce noted, a product consisting entirely of aluminum extrusions, "real" or otherwise, is unlike any of the examples listed. The authority Perfectus cites, see Pl.'s Reply to 56.2 Mot. at 11 n.11, only suggests that lists do not need to be exhaustive. It does not affirmatively suggest that products unlike items entered on a list should receive treatment identical to the listed items. The issue Perfectus faces here is not that the list of example products covered by the finished merchandise exclusion is exhaustive -- it clearly is not -- but instead that the product Perfectus would have covered by the finished merchandise exclusion is substantially unlike any of the examples provided. Perfectus's products consist entirely of aluminum extrusions, whereas all the examples in the Orders are made of both aluminum extrusions and non-aluminum extrusion parts. See, e.g., Antidumping Duty Order, 76 Fed. Reg. at 30,651. For these reasons, the court concludes that Commerce's determination Perfectus's merchandise does not qualify for the finished merchandise exclusion and is within the plain language of the scope is in accordance with law.
B. Commerce Properly Issued a Scope Ruling Without Initiating a Formal Scope Inquiry.
Commerce issued a final scope ruling in this matter without initiating a formal scope inquiry. Perfectus argues that this was inappropriate because the merchandise at issue was not unambiguously within the Orders' scope. The court concludes that Commerce's instructions were proper because the merchandise at issue was unambiguously within the plain language of the Orders' scope.
As discussed above, the plain language of the Orders places the merchandise at issue within the scope, and the finished merchandise exclusion does not cover products consisting entirely of aluminum extrusions. However, Perfectus argues that the 6xxx Final Scope Ruling's reference to the 19 C.F.R. § 351.225(k)(1) factors -- and particularly to prior scope rulings16 -- means that Commerce must have determined that the text of the Orders is ambiguous. Pl.'s 56.2 Br. at 7. Perfectus's contention is unpersuasive. Prior to reaching the (k)(1) analysis, Commerce had determined that the plain language of the Orders sufficed to place the products at issue within the scope. Commerce's subsequent (k)(1) analysis is part of a "belt-and-suspenders" approach, and it would be strange to penalize an agency's analytical thoroughness. The fact that the 6xxx Final Scope Ruling describes how its interpretation is consistent with prior final scope rulings neither means that Commerce's determination *1356relies on this consistency, nor renders the text of the Orders ambiguous.
Finally, Perfectus argues that the fact Commerce previously declined to find that 6xxx pallets were within the scope means that the products at issue in this case were necessarily outside the scope. Pl.'s 56.2 Br. at 23-24 (citing Antidumping and Countervailing Duty Orders on Aluminum Extrusions from the People's Republic of China: Final Scope Ruling on Certain Aluminum Pallets (Dec. 7, 2016), P.R. 31 ("1xxx Final Scope Ruling")). However, the 1xxx Final Scope Ruling declined to make a determination about products made of aluminum alloy in any series other than 1xxx because the record in that proceeding did not include evidence of existing merchandise for any alloy other than 1xxx. For these reasons, the court concludes that Commerce properly issued a scope ruling despite not initiating a formal scope inquiry.
C. Commerce Properly Issued a Scope Ruling Because the Merchandise at Issue Was in Existence.
Perfectus argues that Commerce improperly issued a scope ruling by allegedly deviating from a practice of only issuing scope rulings for products "currently in production." Pl.'s Reply to 56.2 Mot. at 16. Perfectus asserts that the 1xxx Final Scope Ruling and a Federal Register notice are evidence of this practice. See Pl.'s 56.2 Br. at 18-20 (quoting 1xxx Final Scope Ruling at 12; Antidumping and Countervailing Duty Proceedings: Documents Submission Procedures; APO Procedures, 73 Fed. Reg. 3634, 3639 (January 22, 2008) ("Federal Register Notice")). Both the 1xxx Final Scope Ruling and the Federal Register Notice do discuss evidence of production; however, Perfectus mischaracterizes Commerce's practice by ignoring key language in both documents. Commerce explains that its practice is to "not conduct hypothetical scope rulings on products that are not yet in production," 1xxx Final Scope Ruling at 12 (emphasis added); that is, Commerce "will not issue a scope ruling or conduct a scope inquiry on a purely hypothetical product," Federal Register Notice, 73 Fed. Reg. at 3639. In this context, Commerce's determination, as explained in the 6xxx Final Scope Ruling, is consistent with conducting scope inquiries on existing -- i.e., not hypothetical -- products:
[Commerce]'s practice with respect to scope ruling requests is not limited to products which are continuously being imported, but, rather, the requesting party must be able to show that the product is in existence, for instance, by demonstrating that the product is in commercial production or has been imported. We find that the petitioner has satisfied this burden, regardless of whether the merchandise is already imported.
6xxx Final Scope Ruling at 15. Moreover, even were Commerce's decision to issue a scope ruling for a product in existence, but not currently in production, a deviation from its typical practice, Commerce provided an appropriate explanation: "[w]ere we to adopt the view of Perfectus, this would limit our scope rulings only to products which were continually subject to importation, creating a loophole for parties to avoid a ruling on merchandise which might otherwise be subject to an AD/CVD order." Id.; see Consol. Bearings Co. v. United States, 348 F.3d 997, 1007 (Fed. Cir. 2003) ("If that analysis shows that Commerce acted differently in this case than it has consistently acted in similar circumstances without reasonable explanation, then Commerce's actions will have been arbitrary.") (citing RHP Bearings v. United States, 288 F.3d 1334, 1347 (Fed. Cir. 2002) );
*1357Nakornthai Strip Mill Pub. Co. v. United States, 32 C.I.T. 1272, 1276-77, 587 F. Supp. 2d 1303, 1307-08 (2008) (noting that Commerce may "change its policies and practices as long as they are reasonable and consistent with their statutory mandate [and] may adapt its views and practices to the particular circumstances of the case at hand, so long as the agency's decisions are explained and supported by substantial evidence on the record") (quoting Trs. in Bankr. of N. Am. Rubber Thread Co. v. United States, 31 CIT 2040, 533 F. Supp. 2d 1290, 1297 (2007) ); Hyundai Steel Co. v. United States, 41 CIT ----, ----, 279 F. Supp. 3d 1349, 1371 (2017). Thus, Commerce's issuance of a scope ruling was not improper.
D. The Issue of Liquidation Is Moot.
Commerce instructed Customs to continue to suspend liquidation of entries made prior to the date of the 6xxx Scope Ruling Request. See, e.g., Countervailing Duty Order, 76 Fed. Reg. 30,653 at 30,654. As discussed above, the plain language of the Orders places the merchandise at issue here within the scope -- therefore, the products at issue here were clearly subject to suspension of liquidation. See Sunpreme Inc. v. United States, 924 F.3d 1198, 1213 (Fed. Cir. 2019) (noting that "[w]hen, based on examination of the product in question and the plain meaning of the words in an antidumping or countervailing duty order, there is no question that the product is [ ] within ... the scope of the order," Customs' suspension of liquidation is a lawful performance of "its ministerial duties because the duty order in question is not ambiguous as to whether it applies to the particular imported products") (citations omitted). Nonetheless, Perfectus argues that the liquidation of two entries of its merchandise in 2012 demonstrates that suspension of liquidation had never occurred and thus suspension for entries of its products could not "continue.".17 Pl.'s Reply to 56.2 Mot. at 17-18; 6xxx Final Scope Ruling at 15; Pl.'s Suppl. Br. at 2-3.
The suspension of liquidation issue is moot, as it appears that Perfectus's entries were liquidated, without being subject to antidumping or countervailing duties, prior to the initiation of the anticircumvention inquiry. See Perfectus's EOA and APO Application at Ex. A (Mar. 13, 2017), P.R. 10 ("Perfectus's EOA and APO App."). The parties do not dispute that these liquidations are final.18 See Def.'s Resp. to 56.2 Mot. at 23 (noting that "any entries made in 2015 would also have been liquidated before the initiation of the scope inquiry in 2017, presuming they were entered like its two entries on the record and mischaracterized as Type 01"); Pl.'s Reply to 56.2 Mot. at 18 ("All entries of Perfectus' Series 6xxx aluminum pallets in years 2011 to 2015 have been liquidated and are *1358now final.").19 The court therefore can provide no further relief, rendering the issue of Commerce's liquidation instructions to Customs moot. See Heartland By-Prod., Inc. v. United States, 568 F.3d 1360, 1368 (Fed. Cir. 2009) (finding liquidation instruction issue moot when company no longer imported subject merchandise and Customs would not be reliquidating the relevant entries to include the duties).
CONCLUSION
The court concludes that Perfectus timely filed its complaint and that Commerce properly issued the 6xxx Final Scope Ruling finding that (1) the plain meaning of the unambiguous language of the Orders includes the merchandise at issue, and (2) the finished merchandise exclusion does not cover the products at issue because they consist entirely of aluminum extrusions without initiating a formal scope inquiry. Commerce's determination is sustained.
SO ORDERED.
