   OPINION and ORDER

Pogue, Senior Judge:

In these cases, Plaintiff SunPower Corp. (“SunPower”) contests aspects of the final affirmative determinations made by the U.S. Department of Commerce (“Commerce”) in its antidumping and countervailing duty (“AD” and “CVD,” respectively) investigations of solar cells and panels from the People’s Republic of China. The court has jurisdiction over these actions pursuant to Section 516A(a)(2)(B)(i) of the Tariff Act of 1930, as amended, 19 U.S.C. § 1516a(a)(2)(B)(i) (2012), and 28 U.S.C. § 1581(c) (2012).

Currently before the court are ten motions, all of which concern the standing of SunPower and that of its wholly owned subsidiary, SunPower Corporation, Systems (“Systems”) in these matters.

As explained below, both SunPower and Systems were interested parties who participated in the underlying administrative proceedings at issue here, and therefore each has standing to challenge the administrative determinations in its own right. Accordingly, Plaintiffs motions to amend the complaints and extend the preliminary injunctions to cover its wholly owned subsidiary are granted, while Defendant’s and Defendant-Intervenor’s motions to dismiss are denied.

BACKGROUND

The two cases currently under review are Consolidated Court Number 15-00067 (“15-67”), which concerns challenges to Commerce’s antidumping duty investigation, and Court Number 15-00090 (“15-90”), which concerns challenges to the countervailing duty investigation.

Both cases arise from petitions filed by Defendant-Intervenor SolarWorld Americas Incorporated (“SolarWorld”). Sun-Power participated in both investigations.

Plaintiff timely filed a summons and complaint in 15-67 seeking judicial review of Commerce’s antidumping duty investigation. Plaintiff then moved, in what are now two of the member cases in that consolidated action, Court Numbers 15-00083 and 15-00088, to preliminarily enjoin Defendant from liquidating its subject merchandise. Both motions were granted. Plaintiff now seeks for both its complaint and its injunction to be expanded to cover Systems. Defendant opposes both motions, arguing that Systems does not have standing before this court and that Sun-Power is not empowered to expand the injunction on Systems’ behalf.

SunPower also timely filed a summons and complaint in 15-90. Here, too, Sun-Power moves to amend their complaint to cover Systems, and for a preliminary injunction to prevent liquidation of their entries and those of Systems. The Government and SolarWorld move to dismiss 15-90, and accordingly argue that the Court lacks jurisdiction to grant SunPower’s motions to amend its complaint and preliminarily enjoin.

DISCUSSION

I. Motions to Dismiss in Ct. No 15-90 The arguments to dismiss in 15-90 boil down to a contention that SunPower itself lacks standing to bring this case.

SunPower’s claim of standing is based on 28 U.S.C. § 2631(j)(l)(B), which provides that “in a civil action under [19 U.S.C. § 1516a] only an interested party who was a party to the proceeding in connection with which the matter arose may intervene.... ” (emphasis added).

A SunPower was an Interested Party

19 U.S.C. § 1677(9) defines an “interested party” as, inter alia, “a foreign manufacturer, producer, or exporter, or the United States importer, of subject merchandise....” In the CVD investigation, SunPower asserted status as an importer, based on the entries made by Systems; in the alternative, SunPower claimed that it was a producer by virtue of its toll-produced products. The agency made no determination to the contrary. Similarly, the Defendant’s motion to dismiss does not claim that SunPower was not an interested party. SunPower was therefore an interested party.

B. SunPower was a Party to the Proceeding.

While there is no statutory definition of “party to the proceeding,” Commerce has defined the term as “any interested party that actively participates, through written submissions of factual information or written argument, in a segment of a proceeding.” This Court has previously adopted that definition, holding that a party is a “ ‘party to the proceeding’ only when that party provides factual information or promotes a legal position before Commerce.”

There is no requirement that a party provide both factual information and legal argument. Providing factual data on exports in response to a questionnaire from Commerce is sufficient to make a party a “party to the proceeding.” The addition of relevant information to an otherwise procedural filing changes the character of that filing to meaningful participation in the administrative proceeding.

Here, SunPower submitted factual data on exports and sales of goods imported by Systems in response to Commerce’s request. This makes SunPower a “party to the proceeding.”

Accordingly, SunPower is an interested party who was a party to the proceeding, and on that basis, jurisdiction over Sun-Power’s claim is proper. Defendant and Defendant-Intervenors’ motions to dismiss 15-90 are therefore denied.

II. Motions to Dismiss Count VI in 15-67

Plaintiff moves to withdraw Count VI of its complaint in 15-67. Defendant and Defendant-Intervenor move to dismiss Count VI as well. Since there is no disagreement between the parties on this point, SunPower’s motion to withdraw Count VI is granted and Defendant and Defendant-Intervenor’s motions to dismiss Count VI are denied as moot.

III. Motions to Amend in Both 15-67 and 15-90

SunPower has moved to amend its complaints in both 1567 and 15-90 pursuant to USCIT Rules 7(b)(1), 15(a)(2), 15(c)(1), 20, and 21. The chief purpose of these amendments is to add Systems as a party. Defendant and Defendant-Interve-nor oppose the addition of Systems, arguing that Systems was not a party to the underlying administrative proceedings, and further, that Systems should be time-barred because it seeks joinder more than thirty days after Commerce’s final determinations.

USCIT Rule 21 empowers this Court, “[o]n motion or on its own ... [to] at any time, on just terms, add or drop a party.” This equitable power is broad: “Rules 20 and 21, involving, inter alia, the addition of parties, are to be construed liberally in order to promote complete resolution of disputes, thereby preventing multiple lawsuits.”

Despite Defendant and Defendant-In-tervenor’s claims, Systems standing is not time-barred, since, as explained below, the filing date of the amended complaint relates back to the filing date of the original complaint. In addition, Systems has standing in its own right because: Systems has shown that it is an interested party, having imported subject goods during the period of investigation that Commerce knew or should have known about by virtue of Systems’ filings on the administrative record. Systems has shown it was a party to the underlying proceedings because it provided Commerce with factual data regarding those entries in response to questionnaires from the agency.

A. Systems’ Addition is Not Time-Barred, Because the Amended Complaint Relates Back to the Date of the Original Filing.

Systems is not barred by the requirement in 19 U.S.C. § 1516a that a case be filed within thirty days of Commerce’s final determination. Here, the bar is avoided, since “[a]n amendment to a pleading relates back to the date of the original pleading when.... the amendment asserts a claim or defense that arose out of the conduct, transaction, or occurrence set out — or attempted to be set out — in the original pleading.” Because the original complaints described SunPower’s tolling arrangements with its various wholly-owned subsidiaries, and since SunPower’s factual submission in the underlying administrative proceedings were submitted jointly with Systems and discussed entries made by Systems that SunPower now seeks to cover with its amended complaints and expanded preliminary injunctions, as discussed below, it follows from these filings that Commerce had fair notice of Systems’ status and that Systems’ status may therefore relate back to the date of the original filing of the complaints. The thirty-day time bar is therefore satisfied.

B. Systems Has Standing Because it was an Interested Party and a Party to the Proceedings in its Own Right.

SunPower may amend its complaints to add Systems as a party if Systems is an interested party who was a party to the underlying proceedings. If not, Systems lacks standing.

Systems is an interested party if it acted as the importer of record for subject merchandise during the period of investigation. In 15-67, SunPower, with Systems, provided Commerce, in the underlying proceedings, with entry summary documents for three entries of subject merchandise with Systems as the importer of record. In 15-90, SunPower relies similarly on entry documents that describe subject merchandise entered during the period of review with Systems as the importer of record. As Defendant points out, in 15-67 the summary forms erroneously list the importer of record as “SunPower Corporation USA” and not “SunPower Corporation, Systems”; “Sun-Power Corporation, Systems” is identified only as the consignee. However, Commerce knew or had reason to know that these entries were in fact made by Sys-terns because the address and importer number listed on the forms were those of Systems, and “SunPower Corporation USA,” which does not actually exist. Therefore, because Systems served as importer of record of subject merchandise during the periods of investigation for both the AD and CVD administrative proceedings, and Commerce knew or had reason to know of this, Systems is an interested party for the purposes of both 15-67 and 15-90.

Systems next must show that it was a party to the underlying administrative proceedings. As explained above, the statute provides no definition of the term “party to the proceeding,” but Commerce has defined the term as “any interested party that actively participates, through written submissions of factual information or written argument, in a segment of a proceeding.” Purely procedural filings, such as an “[administrative protective order] application and notice of appearance,” unaccompanied by other participation before the administrative agency, are insufficient to create a party to the proceeding. On the other hand, an interested party who responds to a questionnaire from the Department seeking information to use in selecting respondents is a party to the proceedings.

The documents on which SunPower and Systems rely in each case contained factual data on imports to the United States and were submitted to Commerce as a part of the administrative review process. Filings that contain factual data on imports of subject merchandise are enough to establish participation. Further, in 15-67, System’s status as a party to the proceeding is strengthened by the fact that it, in conjunction with SunPower, “responded to a questionnaire from the Department seeking information to use in selecting respondents” — a response that Commerce noted in its preliminary determination and its final determination. Commerce, having “acknowledged implicitly [System’s] participation in the proceeding by responding to [its] submission containing factual information,” cannot now say that Systems is not a party to the proceeding.

Like its parent, Systems provided factual information to Commerce in the underlying proceedings to both 15-67 and 15-90, and is therefore entitled to participate in both cases as a party to the underlying proceedings in its own right. Plaintiffs motions to amend its complaints to add Systems as a co-plaintiff are accordingly granted.

IV. Systems is Entitled to the Protection of the Previously-Granted Preliminary Injunction in 15-67.

It is uncontested that, if Systems can be added to this litigation in its own right, and the litigation survives the motions to dismiss, it also has the right to expand the existing preliminary injunction in 15-67 to protect its entries from liquidation. Parties spend much ink arguing about whether or not SunPower possesses independent authority to expand the scope of its previously-granted preliminary injunction to cover Systems’ entries. However, this issue does not need to be addressed. Systems having standing, and having therefore properly been joined to this litigation for the reasons described above, Systems is therefore granted an expansion to the preliminary injunction to cover all entries of subject merchandise made during the period covered by the previously-granted preliminary injunctions, leave for Systems to expand the preliminary injunction to protect its entries during the time period covered by the previously-granted preliminary injunction is therefore granted.

V SunPower and Systems are Entitled to a Preliminary Injunction in 15-90.

In opposing SunPower’s motion for a preliminary injunction in 15-90, Defendant claims solely that “the Court should deny SunPower’s [and Systems’] motion because SunPower lacks standing to bring this action and, thus, is not entitled to injunctive relief.” However, as explained in Sections I through III, swpra, SunPower and Systems do both have standing.

For the same reasons supporting the grant of preliminary injunctions against liquidation of SunPower and System’s subject entries in the cases consolidated into 15-67, SunPower and Systems are entitled to an injunction in 15-90. Their motion, as amended, is granted.

CONCLUSION

SunPower has established that, by submitting factual data to Commerce, it participated in the underlying administrative proceedings; accordingly, this court has jurisdiction and the motions to dismiss 15-90 must be denied. SunPower’s motion to dismiss Count VI of 15-67 is granted as unopposed, and in consequence Defendant and Defendant-Intervenor’s motions to dismiss Count VI are denied as moot. SunPower has also established that its wholly-owned subsidiary, Systems, joined it on its factual submissions, thereby giving Commerce notice of Systems’ separate status and as an interested party who was a party to the proceedings. SunPower may therefore amend its complaints in both actions to include Systems as a party because it has shown that Systems was an interested party and a party to the underlying administrative proceedings. Systems has accordingly established standing before this court in both cases, entitlement to protection under the previously-granted preliminary injunction in 15-67, and to protection under the newly granted preliminary injunction in 15-90. The amended complaints relate back to the filing date of the original complaints, and therefore the thirty-day time bar is not implicated.

For the above-stated reasons, Defendant and SolarWorld’s motions to dismiss are denied, Plaintiffs motions to amend are granted, Plaintiffs motion to expand the preliminary injunctions in 15-67 to cover co-plaintiff Systems is granted, and the motion for a preliminary injunction in 15-90 as to both SunPower and Systems is granted.

No. 15-00090, ECF Nos. 32 & 33, and the agency made no such determination, see CVD Final Determination, 79 Fed. Reg. 76, 962, and accompanying Issues & Decision Mem., C-570-011, Investigation (Dec. 15, 2014). Arguments omitted from a party’s briefing are waived. See United States v. Great American Ins. Co. of NY, 738 F.3d 1320, 1328 (Fed.Cir.2013) ("It is well established that arguments that are not appropriately developed in a party’s briefing may be deemed waived.” (citations omitted)).

      . Defendant’s position here is that the lack of an argument accompanying the data dooms SunPower's attempt at participation. Def’s Mot. to Dismiss, Ct. No. 15-00090, ECF No. 32 p. 4-9. Legacy holds that a party is a party to the proceeding "only when that party provides factual information or promotes a legal position before Commerce.” Legacy Classic Furniture, 774 F.Supp.2d at 1294. In effect, Defendant argues that the 'or' in Legacy should be read as ‘and.’
      To support this proposition, Defendant cites Specialty Merchandise Corp., in which a plaintiff was found to have been a party to the proceeding because it had submitted both facts and argument. Specialty Merchandise Corp. v. United States, 31 C.I.T. 364, 365-66, 477 F.Supp.2d 1359, 1361 (2007); see Def’s Mot. to Dismiss, Ct. No. 15-00090, ECF No. 32 p. 7-8. There, this Court affirmed Commerce’s determination that Specialty Merchandise was a party to the proceeding because it made written submissions containing argument. Defendant now appears to argue that by agreeing that evidence backed by argument was one valid form of participation, this Court somehow conjured up a requirement that only evidence linked to argument counts as participation. Def's Mot. to Dismiss, Ct. No. 15-00090, ECF No. 32 p. 7. This is not the case. The fact-to-argument link is sufficient to establish participation, but it is not necessary. See Union Steel v. United States, 33 C.I.T. 614, 618-19, 617 F.Supp.2d 1373, 1378-79 (2009).

Squibb & Sons, Inc. v. Lloyd’s & Companies, 241 F.3d 154, 163 (2d Cir.2001). Leave to amend should be given freely absent "apparent or declared reason ... such as undue delay, bad faith or dilatory motive on the part of the movant, repeated failure to cure deficiencies by amendments previously allowed, undue prejudice to the opposing party by virtue of allowance of the amendment, futility of amendment.” Foman v.

Defendant has not shown bad faith, prejudice, futility, or any other meaningful potential disadvantage. Commerce’s parade of horribles here is unpersuasive: SunPower is not attempting to parachute previously unsuspected time-barred corporations into this litigation years after the fact. The rules would prohibit this, and will continue to do so in the future. Rather, they are attempting, several months after filing their complaint and promptly after discovering a defect in their pleading, to correct that defect in order to preserve the ability to challenge liquidation of the same entries they had apparently intended to protect in the first place.
