MilleR, Judge.
This appeal is from the order of the U.S. Customs Court denying a motion by N. C. Trading Co., Inc.1 (“N. C. Trading”) to intervene in Aireo, Inc. v. United States, Customs Court No. 76-3-00643. We affirm.
BACKGROUND
Aireo, Inc. (“Aireo”), an American manufacturer of ferrochrome, brought suit in the Customs Court under section 516(d) of the Tariff Act of 1930, as amended, (19 USC 1516(d)),2 challenging a determination by the Secretary of the Treasury (“Secretary”) that bounties or grants are not being bestowed on ferrochrome imported from the Republic of South Africa within the meaning of Section 303 of the Tariff Act of 1930, as amended, (19 USC 1303).
In its motion to intervene in the Customs Court, N. C. Trading argued that (1) as an importer-consignee of merchandise involved in a section 516(d) proceeding, it has a statutory right under section 516(f) of the Tariff Act of 1930, as amended (19 USC 1516(f)),3 to [13]*13intervene because actions under section 516 have been three-party actions since 1922 and, in enacting the Trade Act of 1974,4 Congress did nothing to change this; (2) the failure of the Customs Court to allow it to participate would raise serious constitutional questions because of its direct and substantial interest in the proceedings, which interest is not adequately represented by the existing parties; and (3) the Customs Court should look to Fed. R. Civ. P. 24(a) for guidance.
Both Aireo and the Government opposed N. C. Trading’s motion, arguing that (1) N. C. Trading failed to establish that it was a consignee of ferrochrome from South Africa; (2) the statute does not authorize a consignee of merchandise subject to a proceeding under section 516(d) to appear and be heard as a party in interest; (3) there is no constitutional right to participate; and (4) N. C. Trading failed to meet the criteria set forth in Fed. R. Civ. P. 24(a), which in any event is not applicable to the Customs Court. On December 14, 1977, the Customs Court denied N. C. Trading’s motion to intervene without opinion. N. C. Trading filed a motion for rehearing which was denied on February 28, 1978, without opinion.
On April 28, 1978, N. C. Trading filed a notice of appeal with this court and moved for a stay of the proceedings in the Customs Court pending disposition of the appeal. After a series of oppositions and cross-motions,5 this court, on June 7, 1978, ordered a stay of the proceedings before the Customs Court pending disposition of the appeal and directed the court below to supplement the record with findings of fact and conclusions of law on which the orders of December 14, 1977, and February 28, 1978, were based.
CUSTOMS COURT
Pursuant to this court’s direction, the Customs Court transmitted on June 30, 1978, the following findings of fact:
1. that section 1516(f) employs the definite article “The” before the word “consignee” and not the indefinite article “A” before such word as contended for by the movant, and, therefore, the word “consignee” has limited textual application;
2. that the validity of section 1516(d) was not challenged by the movant on any constitutional grounds in its motion to intervene.
The Customs Court also transmitted the following conclusions of law:
1. that the words “The consignee” in section 1516(f) refer solely to the consignee of the entry underlying the three party
[14]*14action provided for in 19 U.S.C. § 1516(c) between the American manufacturer, the United States, and the consignee of an entry of merchandise upon which the action is predicated and whose right to intervene is provided for in rule 5.1 of the Customs Court rules;
2. that section 1516(d) provides only for the maintenance of a two party action in the Customs Court between the American manufacturer and the United States, independent of any particular entry of merchandise; and
3. that absent a statutory basis the movant lacks standing to intervene, and the Customs Court lacks power to permit intervention of additional parties not properly before the court.
OPINION
This appeal presents three issues for resolution: (1) Whether N. C. Trading has established that it is a “consignee” of merchandise of the same kind as that involved in the Customs Court proceedings, namely: South African ferrochrome; (2) whether the Constitution requires that section 516 be so construed that a consignee of merchandise of the same kind as that involved in an action under section 516(d) has a right to appear and be heard as a party in interest; and (3) whether a consignee of merchandise of the same kind as that involved in a section ‘516(d) action has a statutory right under section 516(f) to appear and be heard as a party in interest.
1. N.G. Trading’s status as a consignee
Appellees 6 argue that N.C. Trading has not established its alleged consignee status, “but relied solely on the self-serving statement that it is a consignee of South African Ferrochrome and on an unverified list of entries of ferrochrome purportedly made by N.C. Trading during 1976-77.” Nevertheless, schedule A of N.C. Trading’s original motion to intervene listed fifteen entries totaling over 35 million content pounds of South African ferrochrome imported during the period preceding the filing of that motion — March 12, 1976, through August 3, 1977— for which N.C. Trading paid over $222,000 in duties.7 With its motion for rehearing, N.C. Trading submitted a certified copy of the consumption entry form, along with supporting documents, for entry No. 234735, which is listed on Schedule A.8 These exhibits are sufficient to demonstrate that N.C. Trading imported South African ferrochrome during the pertinent period.
Appellees further argue that “[e]ven if N.C. Trading may have imported South African ferrochrome in June 1977, that does not give [15]*15to the company the eternal and unchanging status of ‘importer-consignee’,” and “there is nothing on the record herein to show whether appellant is in the business of importing ferrochrome from South Africa, is currently importing ferrochrome, or will be importing such merchandise in the future from South Africa when this case is finally concluded.” While the remedy provided by section 516(d), which is discussed infra in greater detail, is prospective in nature, i.e., to protect a domestic manufacturer from future importations, the basis of such a proceeding is a determination by the Secretary “that a bounty or grant is not being paid or bestowed.” The Secretary must, therefore, look to the foreign government’s current and past practices with respect to current and past exportations (although no specific entry is involved in a section 516(d) proceeding) to make his determination. Therefore, in light of N. C. Trading’s demonstration of importations of South African ferrochrome immediately preceding its motion to intervene, we conclude that it has sufficiently demonstrated its status as a consignee of merchandise of the same kind as that involved in the Customs Court proceedings.
2. Statutory construction of section 516
A. Historical development
Section 516, which first appeared in the Tariff Act of 1922, is unique in its authorization of intervention in a proceeding in the Customs Court. Under the 1922 act, section 516 permitted a domestic manufacturer to challenge the appraised value, the classification, or the rate of duty of imported merchandise of the kind manufactured by him. When dissatisfied with the action taken by the appraiser or the Secretary, the domestic manufacturer could, under appropriate circumstances, file either an appeal for reappraisement or a protest in connection with a specific entry. Tariff Act of 1922, ch. 356, §§ 516(a)-(b), 42 Stat. 970-71.
The consignee of the merchandise on the entry involved in the appeal or protest filed by the domestic manufacturer was given the concomitant right to be notified of such action and to appear as a party in interest. Id., § 516(c), 42 Stat. 971.9 Moreover, the consignee’s right to prevent the confidential information contained in the entry papers from being disclosed to the domestic manufacturer was recognized. Id., § 516(d), 42 Stat. 971.
As carried over into the Tariff Act of 1930, section 516 reserved to the consignee of the merchandise of the disputed entry (in the appeal [16]*16for reappraisement or protest filed by tlie domestic manufacturer) the same rights accorded in the 1922 act.10
Minor changes were made to section 516 prior to the Trade Act of 1974. The provisions of'section 516(d) were transferred to 28 U.S.C. 2634(b),11 and the Customs Courts Act of 1970 reenacted that provision in almost identical language to that of 28 U.S.C. 2637(b).12 The 1970 act also revised section 516 to reflect the consolidation of appraisal and classification functions within the Bureau of Customs. The right of the domestic manufacturer “to contest the appraised value or classification of, or rate or duty assessed upon, the merchandise” was carried over in section 516(c).13 Nevertheless, as in the previous statutes, this right was limited to the merchandise of a designated entry; section 516(c) then provided, in pertinent part:
Upon receipt of notice [of desire to contest] from the petitioner, the Secretary shall cause publication to be made of his decision as to the proper appraised value or classification or rate of duty and of the petitioner’s desire to contest, and shall thereafter furnish the petitioner with such information as to the entries and consignees of such merchandise, entered after the publication of the decision of the Secretary at such ports of entry designated by the petitioner in his notice of desire to contest, as will enable the 'petitioner to contest the appraised value or classification of, or rate of duty imposed upon, such merchandise in the liquidation of one such entry at such port. The Secretary shall direct the appropriate customs officer at such ports to notify the petitioner by mail immediately when the first of such entries is liquidated. [Italic added.]
Section 516(e) preserved the right of the consignee to be heard as a party in interest in these actions.14 Nevertheless, these revisions were not designed to have a substantive effect on the rights of parties under existing laws. H.R. Rep. No. 91-1067, 91st Cong., 2d Sess. 30 (1970), reprinted in [1970] U.S. Code Cong. & Ad. News 3188, 3217.
Throughout the many revisions of the statute, section 516 preserved the right of the consignee to appear and protect its interests in the property which was the subject of the domestic manufacturer’s action. Prior to the Trade Act of 1974, the only three-party suits which could be brought under section 516 involved a domestic manufacturer, the Government, and the consignee of the designated entry which was the [17]*17subject of the action. The statute made no provision for participation by other “interested” consignees.
B. The Trade Act of 1974
The Trade Act of 1974 amended sections 516 (a), (b), and (c) to provide for judicial review of negative countervailing duty determinations by the Secretary. Trade Act of 1974, Public Law No. 93-618, § 331, 88 Stat. 2052-53.15 The amendment followed this court’s decision in United States v. Hammond Lead Products, Inc., 58 CCPA 129, C.A.D. 1017, 440 F. 2d 1024 (1971), which held that judicial review of negative countervailing duty determinations was not available to domestic manufacturers. H.R. Rep. No. 93-571, 93d Cong., 1st Sess. 76-77 (1973); S. Rep. No. 93-1298, 93d Cong., 2d Sess. 185 (1974), reprinted in [1974] U.S.C. Cong. & Ad. News 7186, 7320.16
The House version of H.R. 10710, which became the Trade Act of 1974, retained the language of the previous sections 516 (a), (b), and (c), except that it provided for judicial review of the failure of the Customs Service to assess countervailing duties in the liquidation of a designated entry at a specified port.
H.R. 10710, as reported by the Senate Finance Committee, re-designated sections 516 (d), (e), (f), and (g) as 516 (e), (f), (g), and (h), respectively. A new section 516(d) was inserted, providing for judicial review of a negative determination by the Secretary with respect to alleged sales at less than fair value of imported merchandise under section 201 of the Antidumping Act of 1921.17 Action could be initiated by American manufacturers of the same type of merchandise as that described in the Secretary’s negative determination, without reference to any specific entry.18 On the Senate floor, the new section [18]*18was amended to permit domestic manufacturers to obtain judicial review of tbe Secretary’s negative determination under 19 U.S.C. 1303 concerning tbe existence of a bounty or grant.19 Sections 516 (a), (b), and (c) were also amended to provide for judicial review of the failure of the Customs Service to assess antidumping duties in tbe liquidation of a designated entry at a specified port.
It is to be emphasized that tbe Trade Act of 1974, while continuing authority for countervailing duty proceedings (with the added judicial [19]*19review of a negative determination) under section 516(c) 20 also preserved the right of the consignee of the liquidated entry involved (sec. 516(f)). Moreover, it created a new cause of action under section 516(d) for a dissatisfied domestic manufacturer to challenge the Secretary’s negative determination under the countervailing duty provisions without designating any particular entry, such as provided by section 516(c).
C. Analysis
N. 0. Trading argues that an action under section 516 has been, and continues to be a three-party action, including an American manufacturer, the Government, and a consignee, saying:
The legislative history shows that Congress merely intended to make clear the scope of judicial review available to American manufacturers without otherwise distrubing the substance of Section 516. Nowhere in the legislative history of Section 516 is there a single expression of congressional intent to exclude a consignee from a proceeding brought pursuant to Section 516(d) or to change what had been for over 50 years a three party action to a two party action.
However, we are persuaded that appellant’s argument is premised on a misunderstanding of section 516 proceedings prior to the 1974 amendment. Indeed, appellant furnishes the key to the resolution of this issue in its brief, thus:
This provision [section 516 before the 1974 amendment] manifests Congress’ recognition, from the very beginning, that a consignee of the merchandise that is the subject of the proceeding under section 516 has a direct and substantial interest in such proceeding. The amendments enacted by the Trade Act of 1974 did not change this. Such a change would, if enacted, have radically altered the very nature of a proceeding under section 516. [Italic added.]
[20]*20Prior to 1974, only a consignee of the merchandise of the entry involved in. the section 516 proceeding had a right to be heard as a party in interest; no other “interested” consignee was authorized to participate as a party in interest.21 We agree with appellant that the Trade Act of 1974 did not alter previous practice. Only a consignee of the merchandise of the entry involved has a right- to participate as a party in interest. Indeed, if any other consignee were allowed to be come a party in interest, such a change would have radically altered the very nature of a proceeding under section 516.
In support of its argument, appellant states that there “is absolutely no authority in the legislative history (and none is cited by the Government) for the proposition that Congress ‘intended’ singular treatment for section 516(d)” and that section 516(f) does not apply exclusively to a cause of action authorized under sections 516 (a), (b), and (c). However, there is no legislative history indicating that Congress intended that the section 516(f) right of “[t]he consignee” to participate as a party in interest applies to section 516(d) proceedings. Moreover, there is no designated entry mentioned in section 516(d), so that there can he no corresponding consignee as required by section 516(f).22 N. C. Trading cites 1 U.S.C. 1 [“In determining the meaning of any act of Congress, unless the context indicates otherwise — words importing the singular include and apply to several persons, parties, or things”] for the proposition that “the definite article ‘The’ before the word ‘consignee’ in section 516(f), instead of the indefinite article ‘A’ before such word, is of little or no significance,” and, thus, “‘the consignee’ in section 516(f) may be construed genetically to include any consignee.” Such citation is unconvincing in light of the clear statutory reference to the consignee in section 516(c) of the Tariff Act of 1930, which provided the context for section 516(e) of the 1970 act (changed to section 516(f) by the Trade Act of 1974).
Interpreting section 516(d) to authorize only two-party actions, involving the domestic manufacturer and the Government,23 not only [21]*21continues the long-standing practice that consignees of merchandise other than that involved in a section 516 action are excluded from participation, but also is consistent with the absence from section 516(d) of any mention of “consignees.” To interpret section 516(d) as N. C. Trading suggests would open action thereunder to participation by numerous consignees—all past and current importers of merchandise of the kind involved, and even all future or potential importers. It is highly improbable that Congress would have so intended without mentioning it in the legislative history of the Trade Act of 1974.
Although the parties have discussed at some length the application of Fed. R. Civ. P. 24(a),24 which concerns intervention as a matter of right, to section 516(d) proceedings, suffice it to say that appellant’s citation to the Federal Rules of Civil Procedure is inap-posite inasmuch as the rules are expressly made applicable only to the United States district courts. Fed. R. Civ. P. 1; United States v. Torch Manufacturing Co., 62 CCPA 41, 47 n.8, C.A.D. 1143, 509 F. 2d 1187, 1192 n.8 (1975). See 28 U.S.C. 2072.25
8. Constitutional considerations26
1ST. C. Trading argues that if it were excluded from a proceeding under section 516(d), it would “be deprived of * * * property, without due process of law” 27 and be denied the right of access to the courts.28
[22]*22This argument rests on the contention that if Aireo were successful in this litigation, N. C. Trading would be (1) required to pay “substantial premiums for bonds,” as did the importers of the merchandise after the Customs Court’s reversal of the Secretary’s decision in Zenith, Radio Corp. v. United States, 437 U.S. 443 (1978), “or incur charges for letters of credit to cover the potential liabilities for countervailing duties” on future imports;29 (2) subjected to business uncertainty due to the suspension of liquidation which would occur;30 and (3) deprived of an opportunity to secure prompt and meaningful administrative and judicial review of any assessment of countervailing duties.
Although a person must be afforded an opportunity for some kind of hearing before being finally deprived of a property interest, all interests do not require the same type of protection. Boddie v. Connecticut, supra note 28. Due process is flexible and demands only such procedural protection as the particular situation demands. Morrissey v. Brewer, 408 U.S. 471, 481 (1972); Cafeteria & Restaurant Workers Union, Local 473 v. McElroy, 367 U.S. 886, 895 (1961). To determine whether the procedures are constitutionally sufficient requires consideration of the governmental and private interests affected. Mathews v. Eldridge, 424 U.S. 319, 335 (1976); Goldberg v. Kelly, 397 U.S. 254 (1970).
In the related field of income tax litigation, the Supreme Court, in the landmark case of Phillips v. Commissioner, 283 U.S. 589, 599 (1930), remarked that—
it has already been shown that the right of the United States to exact immediate payment and to relegate the taxpayer to a suit for recovery, is paramount. The privilege of delaying payment pending immediate judicial review, by filing a bond, was granted by the sovereign as a matter of grace solely for the convenience of the taxpayer. [Footnote omitted.]
Accordingly, the Court concluded, id. at 596-97:
Where only property rights are involved, mere postponement of the judicial inquiry is not a denial of due process, if the opportunity given for the ultimate judicial determination of the liability is adequate.
Phillips has continued to be cited for the principle that the immediate seizure of a property interest, without an opportunity for a prior hearing, is constitutionally permissible when necessary to serve an important governmental or public interest, such as the collection of taxes. Commissioner v. Shapiro, 424 U.S. 614 (1976); Calero-Toledo [23]*23v. Pearson Yacht Leasing Co., 416 U.S. 663 (1974); Fuentes v. Shevin, 407 U.S. 67 (1972). Appellant has cited no departures from this principle.
This court, relying upon Phillips, has held that an importer has no right to a hearing prior to the assessment of duties, if the opportunity given for ultimate judicial review of the determination of liability is adequate. Dart Export Co. v. United States, 43 CCPA 64, 75, C.A.D. 610, cert. denied, 352 U.S. 824 (1956).
Since N. C. Trading has no right to a hearing prior to the assessment of duties,31 we must conclude that it had no right to intervene in the section 516(d) proceeding below in order to be heard before posting bond or other security on importation, or even before paying duties that it believed to be unlawful.
In contending that there will be no prompt and meaningful post-deprivation hearing of any kind,32 appellant says that should the Customs Court reverse the Secretary’s negative countervailing duty determination, liquidation of entries of all South African ferrochrome would remain suspended pending appeal (and any certiorari petitions); that during this period appellant would be exposed to the possibility of additional duties of an unknown amount;33 and that, were Aireo to ultimately prevail on appeal, only after the Secretary determined the actual amount of the countervailing duties to be imposed would the entries be liquidated and N. C. Trading have its first opportunity to protest the decision. Appellant also suggests that its protest could only be denied in light of the judicial precedent, so that it would not have any meaningful administrative review.34 However, there would be no adverse impact on appellant unless a court of competent jurisdiction holds that countervailing duties should be imposed. Although an importer would be “relegated to the sidelines” during any appeal therefrom, shortly after a decision on appeal it would have the right to protest any countervailing duty assessed35 and to file a summons and complaint. We are satisfied that the delays involved would not be excessive, so that there would be no violation of either the First or Fifth Amendments. Indeed, appellant’s position is not materially different from that of an importer involved in the usual [24]*24classification or valuation dispute which, although dissatisfied with the amount of duty, may have a long wait for the appropriate customs officer to liquidate his entry. See United States v. Nils A. Boe, Chief Judge, United States Customs Court, 64 CCPA 11, C.A.D. 1177, 543 F. 2d 151 (1976); Dart Export Corp. v. United States, supra. Appellant’s contentions are more appropriately directed to the financial risk-taking necessarily associated with the import business. Like many successful litigants, N. C. Trading, even if it prevails, will never be entirely whole since it will have endured business uncertainty, loss of interest, the payment of attorneys’ fees, and the expenditure of executives’ and employees’ time.
Regarding appellant’s point that it would be difficult to obtain meaningful judicial review, we note that, in numerous test cases brought by importers before the Customs Court, there are other importers of the same kind of merchandise that is the subject of the litigation, which importers are not parties to the particular litigation, although they have an interest in, and stand to be affected by, a decision in a particular test case. However, an “interested” nonparty who is displeased over the outcome of a test case is free to bring its own action with a view to improving the record,36 rearguing the law, and urging that the earlier decision should not be followed. See United States v. Stone & Downer Co., 274 U.S. 225 (1927). If and when N. C. Trading becomes a consignee subjected to the payment of countervailing duties, it will be entitled to review of every aspect of a protested administrative decision. We agree with the following statement of appellee Aireo:
Under N. C. Trading’s theory, none of those “interested” non-parties could obtain meaningful judicial review that would pass Constitutional muster in a later case because of the precedential value of the earlier adverse decision — notwithstanding the Supreme Court’s recognition and approval of the “relitigation” practice in the customs tribunals. Stone & Downer, supra. Clearly, that N. C. Trading has no statutory right to participate in the subject American manufacturer’s proceeding (just as an interested American manufacturer has no right to participate in an importer’s action challenging the assessment of countervailing . duties) is totally without Constitutional significance.
Although appellant argues that the Government will not adequately represent its interests in the proceeding below, it will have an opportunity, if countervailing duties are assessed on its imports, to fully represent its own interests in the Customs Court.
In view of the foregoing, we hold that the Constitution does not require that section 516 be so contrued that a consignee of merchandise of the same kind as that involved in an action under section 516(d) [25]*25has a right to appear and be heard as a party in interest; further, that a consignee of merchandise of the same kind as that involved in a section 516(d) action does not have a statutory right under section 516(f) to appear and he heard as a party in interest.
The order of the Customs Court denying N. C. Trading’s motion to intervene is affirmed.
