Defendants-appellants the Oklahoma Tax Commission and its individual members, Cindy Rambo, Robert Wadley and Don Kil-patrick, (collectively “the Tax Commission”) appeal from an order entered by the district court following a remand by this court after our earlier opinion was affirmed in part and reversed in part by the Supreme Court. The Tax Commission contends that the district court’s order does not comply with the Supreme Court mandate. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.
Plaintiff-appellee the Citizen Band Pota-watomi Indian Tribe of Oklahoma (“the Tribe”) owns and operates a convenience store located on land held in trust for it by the Federal Government. The Tribe sells cigarettes at the convenience store but has never collected the state tax on the sales of cigarettes. In 1987, the Tax Commission served an assessment notice on the Tribe demanding $2.7 million for taxes on cigarette sales from 1982 to 1986.
The Tribe filed suit seeking to enjoin the Tax Commission from “entering plaintiff’s Indian Country and from enforcing or attempting to enforce its regulatory and taxing authority to assess a cigarette tax against plaintiff, plaintiff’s officers, agents or employees.” Compl., Appellant's App. at 6-7. The Tax Commission counterclaimed for declaratory and injunctive relief. Answer & Countercl., Appellant’s App. at 21-22.
After denying the Tribe’s motion to dismiss the counterclaim, the District Court reached the merits of the case on stipulated facts. The district court concluded that the Tax Commission lacked authority to tax on-reservation cigarette sales to tribal members or to tax the tribe directly. The district court held that the Tribe was immune from the Tax Commission’s suit to collect *945past unpaid taxes directly from the Tribe but that the Tax Commission could require the Tribe to collect taxes prospectively for on-reservation sales to nontribal members and to comply with statutory record keeping requirements. See Citizen Band Pota-watomi Indian Tribe v. Oklahoma Tax Comm’n, No. CIV-87-0338-W, slip op. at 9, 12, 1988 WL 122606 (W.D.Okla. Apr. 15, 1988) (order granting preliminary injunction), reprinted in Appellant’s App. at 45, 48; Citizen Band Potawatomi Indian Tribe v. Oklahoma Tax Comm’n, No. CIV-87-0338-W, slip op. at 1-3 (W.D.Okla. May 6, 1988) (judgment granting permanent injunction), reprinted in Appellant’s App. at 51-53. While the district court permanently enjoined the Tax Commission from assessing any state sales taxes against or collecting any state sales tax from the Tribe, and collecting any state sales taxes on purchases by tribal members, it ordered the Tribe to aid the Tax Commission in the collection of taxes on purchases of cigarettes by nontribal members. Potawatomi Indian Tribe, No. CIV-87-0338-W, slip op. at 2 (W.D.Okla. May 6, 1988) (judgment granting permanent injunction), reprinted in Appellant’s App. at 52.
The Tribe appealed the order denying its motion to dismiss the Tax Commission’s counterclaim and the order denying its request for a permanent injunction on the Tax Commission’s collection of taxes on purchases by nontribal members. The Tax Commission cross-appealed the district court’s ruling that the Tribe and its members who purchase cigarettes are tax exempt. We held that, because the Tribe was immune from suit, the district court lacked jurisdiction to adjudicate the Tax Commission’s counterclaim. Citizen Band Pota-watomi Indian Tribe v. Oklahoma Tax Comm’n (“Potawatomi I”), 888 F.2d 1303, 1305 (10th Cir.1989). We reversed the district court’s denial of the Tribe’s motion to dismiss the Tax Commission’s counterclaim and remanded with instructions to dismiss the counterclaim. Id. Additionally, we held that the district court erred in denying the Tribe’s request to enjoin the Tax Commission from collecting state sales tax on the Tribe’s sales of cigarette’s (to nontribal members), and we remanded to the district court for a reinstatement of a permanent injunction on behalf of the Tribe. Id. at 1307.
The district court issued an order on remand permanently enjoining the Tax Commission from assessing against and collecting from the Tribe any state sales tax and from entering the Tribe’s Indian Country and from enforcing or attempting to enforce its regulatory and taxing authority to assess a cigarette tax against the Tribe. Citizen Band Potawatomi Indian Tribe v. Oklahoma Tax Comm’n, No. CIV-87-0338-W, slip op. at 9-10 (W.D.Okla. Jan. 4, 1990) (order on first remand), reprinted in Appellant’s App. at 73-74. The district court also dismissed the Tax Commission’s counterclaim for declaratory and injunctive relief. Id.
Meanwhile, the Supreme Court granted the Tax Commission’s petition for a writ certiorari.1 Oklahoma Tax Comm’n v. Citizen Band Potawatomi Indian Tribe, — U.S.-, 111 S.Ct. 37, 112 L.Ed.2d 14 (1990). Affirming our opinion in part, the Supreme Court held that the Tribe’s sovereign immunity barred the Tax Commission’s counterclaim. Oklahoma Tax Comm’n v. Citizen Band Potawatomi Indian Tribe, — U.S. -, 111 S.Ct. 905, 909-10, 112 L.Ed.2d 1112 (1991). The Court subsequently addressed whether the Tribe’s sovereign immunity prevents it from being liable for the collection of state taxes on the sale of cigarettes to nontribal members.2 Id., Ill S.Ct. at 910. Revers*946ing our opinion in part, the Court held that notwithstanding the Tribe’s sovereign immunity, the Tax Commission has the authority to tax sales of cigarettes to nontri-bal members. Id. at 911. The Court reaffirmed “the proposition that the doctrine of tribal sovereign immunity does not prevent a State from requiring Indian retailers doing business on tribal reservations to collect a state-imposed cigarette tax on their sales to nonmembers of the Tribe.” Id. See Washington v. Confederated Tribes of Colville Reservation, 447 U.S. 134, 159-61, 100 S.Ct. 2069, 2084-85, 65 L.Ed.2d 10 (1980); Moe v. Confederated Salish & Kootenai Tribes, 425 U.S. 463, 481-83, 96 S.Ct. 1634, 1645-46, 48 L.Ed.2d 96 (1976). The Supreme Court remanded the case to this court for further proceedings in conformity with the opinion. See Oklahoma Tax Comm’n v. Citizen Band Potawatomi Indian Tribe, — U.S.-, 111 S.Ct. 905, 112 L.Ed.2d 1112 (1991) (remand order), reprinted in Appellant’s App. at 131.
We subsequently issued an order on remand affirming our previous decision “except for that language in the opinion that conflicts with the decision of the Supreme Court.” Citizen Band Potawatomi Indian Tribe v. Oklahoma Tax Comm’n (“Po-tawatomi II”), 932 F.2d 1355 (10th Cir.1991). We “remanded to the district court for dismissal of the Oklahoma Tax Commission’s counterclaim and entry of an injunction prohibiting the Tax Commission from enforcing the challenged assessment for previously uncollected taxes against the ... Tribe.” Id. at 1356.
On remand, the district court adopted in part its earlier judgment on remand from this court issued prior to our opinion being affirmed in part and reversed in part by the Supreme Court:
The Judgment entered by this Court on January 4, 1990, dismissed the defendants’ counterclaim and enjoined the [Tax Commission] from enforcing the challenged assessment for previously uncollected taxes against [the Tribe]. Thus, the Judgment of January 4, 1990, is consistent with the Tenth Circuit’s Order on Remand of May 16, 1991. Therefore, this Court pursuant to the Order on Remand ADOPTS that portion of its Judgment of January 4, 1990, and ADJUDGES that such portion shall remain and is hereby in force and effect.3 *947Citizen Band Potawatomi Indian Tribe v. Oklahoma Tax Comm’n, No. 87-0338, slip op. at 2 (W.D.Okla. Jul. 31, 1991) (order of dismissal and entry of injunction on second remand), reprinted in Appellant’s App. at 145.
The Tax Commission presently contends that this order does not comply with the Supreme Court mandate. According to the Tax Commission, the Supreme Court decided that the Tribe must collect state taxes on sales of cigarettes to nontribal members, and the Tax Commission seeks an order to this effect.
The Supreme Court clearly expressed its agreement with the Tax Commission’s argument that “the Potawatomis’ tribal immunity notwithstanding, [the Tax Commission] has the authority to tax sales of cigarettes to nontribal members at the Tribe’s convenience store.” Oklahoma Tax Comm’n, 111 S.Ct. at 911. Furthermore, the Supreme Court’s rejection of our distinction in Potawatomi I between this ease and Colville supports the Tax Commission’s claim that the Tribe has a legal obligation to assist in the collection of taxes on sales of cigarettes to nontribal members.4 See id. at 911-12. See also Colville, 447 U.S. at 159-61, 100 S.Ct. at 2084-85; Moe, 425 U.S. at 481-83, 96 S.Ct. at 1645-46.
Nevertheless, the Supreme Court’s opinion does not permit the Tax Commission to enforce the Tribe’s legal obligation through the federal courts. The Supreme Court addressed this very contention and implicitly recognized' that the Tax Commission could not rely on federal courts to directly compel the Tribe to comply with its legal obligation to assist-the State in the collection of taxes. The Court stated:
In view of our conclusion with respect to sovereign immunity of the Tribe from suit by the State, Oklahoma complains that, in effect, decisions such as Moe and Colville give them a right without any remedy. There is no doubt that sovereign immunity bars the State from pursuing the most efficient remedy....
Oklahoma Tax Comm’n, 111 S.Ct. at 912 (emphasis added). The Court suggested alternative remedies which included bringing a suit for damages against the agents or officers of the Tribe, id. (citing Ex parte Young, 209 U.S. 123, 28 S.Ct. 441, 52 L.Ed. 714 (1908)), collecting the sales tax from cigarette wholesalers, id. (citing Colville, 447 U.S. at 161-62, 100 S.Ct. at 2085; City Vending of Muskogee, Inc. v. Oklahoma Tax Comm’n, 898 F.2d 122 (10th Cir.), cert. denied, — U.S. -, 111 S.Ct. 75, 112 L.Ed.2d 48 (1990)), entering into an agreement with the Tribe to collect the taxes, id. (citing 25 U.S.C. § 476), or seeking appropriate legislation from Congress. Id. While we do not believe that these are necessarily the exclusive remedies available to the Tax Commission, the Supreme Court’s opinion forecloses federal courts from directly enforcing the Tribe’s obligation to collect taxes on cigarette sales to nontribal members. Nothing in the District Court’s order on remand precludes the Tax Commission from pursuing the remedies that the Supreme Court has indicated are available to it.
*948The district court precisely followed our remand order which instructed it to dismiss the Tax Commission’s counterclaim and enter an injunction prohibiting the Tax Commission from enforcing the challenged assessment for previously uncollected taxes against the Tribe. Potawatomi II, 932 F.2d at 1356. In going no further, the district court recognized its lack of discretion when confronted with a specific mandate by this .court. See Rutherford v. United States, 806 F.2d 1455, 1460 (10th Cir.1986) (“district court is ... bound by the appellate court mandate”). Further, the district court order follows the well-settled principle that an injunction must be narrowly tailored to remedy the harm shown. See Gulf Oil Corp. v. Brock, 778 F.2d 834, 842 (D.C.Cir.1985).
As the district court is bound by our mandate, we of course are bound by the Supreme Court’s mandate. Here, the Supreme Court’s mandate was very general by remanding to this court for proceedings consistent with the Supreme Court’s opinion. See Oklahoma Tax Comm’n v. Citizen Band Potawatomi Indian Tribe, — U.S.-, 111 S.Ct. 905, 112 L.Ed.2d 1112 (1991) (remand order), reprinted in Appellant’s App. at 131. The Tax Commission has not contended that our order on remand from the Supreme Court is inconsistent with the Supreme Court’s opinion; however, by challenging the district court’s order which narrowly follows our mandate, the Tax Commission suggests that our mandate was incomplete. Nonetheless, we cannot order the district court to memorialize the Supreme Court’s recognition of the Tribe’s legal obligation to assist the Tax Commission in the collection of taxes on the sale of cigarettes to nontribal members into a legal order punishable by contempt. To do so would effectively grant the Tax Commission part of the relief it sought in its counterclaim which is barred by the Tribe’s sovereign immunity.5 Oklahoma Tax Comm’n, 111 S.Ct. at 909-10.
AFFIRMED.
. The Court’s stated purpose in granting certio-rari was "to resolve an apparent conflict with [the] Court’s precedents and to clarify the law of sovereign immunity with respect to the collection of sales taxes on Indian lands." Oklahoma Tax Comm 'n v. Citizen Band Potawatomi Indian Tribe, - U.S. -, 111 S.Ct. 905, 909, 112 L.Ed.2d 1112 (1991).
. The Supreme Court rejected the Tribe’s argument that this issue was not properly before the Court because the only issue presented in the Tribe’s prayer for injunctive relief was whether the Tax Commission could require it to pay the challenged assessment for previously uncollected taxes. In rejecting the Tribe’s claim, the Court reasoned:
*946The Tribe’s complaint alleged that [the Tax Commission] lacked authority to impose a sales tax directly upon the Tribe. The District Court held that the Tribe could be required to collect the tax on sales to nonmembers. The Court of Appeals reversed the decision of the District Court on this point. While neither of these courts need have reached that question, they both did. The question is fairly subsumed in the "questions presented” in the petition for certiorari, and both parties have briefed it. We have the authority to decide it, and proceed to do so.
111 S.Ct. at 911 (citing Vance v. Terrazas, 444 U.S. 252, 258-59 n. 5, 100 S.Ct. 540, 544-45 n. 5, 62 L.Ed.2d 461 (1980)). We do not fully understand the Supreme Court’s reasoning that neither we nor the district court were required to reach this point. The district court addressed the issue as it was presented in the Tax Commission’s counterclaim which the district court had erroneously held was not subject to dismissal on sovereign immunity grounds. We addressed the issue because the Tribe appealed directly from that part of the district court's order which denied its motion for a permanent injunction as to the collection of taxes from the sale of cigarettes to nontribal members. Nonetheless, the Supreme Court’s discretionary authority to "clarify the law," see supra note 1, is quite distinct from an inferior court’s authority to grant relief on matters properly before it.
. The Federal Rules of Civil Procedure provide that ”[e]very order granting an injunction ... shall set forth the reasons for its issuance; shall be specific in terms; [and] shall describe in reasonable detail, and not by reference to the complaint or other document, the act or acts sought to be restrained....” Fed.R.Civ.P. 65(d). These requirements are mandatory and should "apprise the party enjoined of the course of conduct which is prohibited." B & C Truck Leasing, Inc. v. ICC, 283 F.2d 163, 167 (10th Cir.1960). See also 7-pt. 2 James Wm. Moore, Moore’s Federal Practice, ¶ 65.11, at 65-137 (2d ed. 1991). The requirements of Rule 65(d) are not purely technical, but serve to "prevent uncertainty and confusion” by those faced with injunctive orders and to “avoid the possible founding of a contempt citation on a decree too vague to be understood,” as well as to facilitate informed and intelligent appellate review. Schmidt v. Lessard, 414 U.S. 473, 476, 94 S.Ct. 713, 715, 38 L.Ed.2d 661 (1974) (per curiam).
Arguably, the district court’s order does not strictly comply with Fed.R.Civ.P. 65(d) as it describes in part the conduct enjoined by refer*947ence to its earlier order. Nonetheless, given the Tax Commission’s failure to challenge the injunction on these grounds, and the apparent understanding by all concerned that the injunction applies only to acts by the Tax Commission to collect the previously imposed assessment, we believe the district court’s order describes in "reasonable detail” the conduct enjoined as required by Fed.R.Civ.P. 65(d).
. In Colville, the Supreme Court held that tribal sellers have an obligation to collect and remit state taxes on cigarette sales to nontribal members. 447 U.S. at 159-61, 100 S.Ct. at 2084-85. Similarly, in Moe, also relied on by the Oklahoma Tax Comm'n Court, the Supreme Court held that Indian retailers may be required to collect state taxes on sales to non-Indians. Moe, 425 U.S. at 481-83, 96 S.Ct. at 1645-46. In Potawatomi I, we distinguished Colville because the Indian tribe there had opted to come under state jurisdiction pursuant to Pub.L. No. 83-280, 67 Stat. 558 (1953) and Wash.Rev.Code § 37.12.-010 (1957). See Potawatomi I, 888 F.2d at 1307. The Supreme Court rejected this distinction stating that "[njeither Moe nor Colville depended upon the State’s assertion of jurisdiction under Public Law 280." Oklahoma Tax Comm'n, 111 S.Ct. at 911. The Court stated that “it is simply incorrect to conclude that Public Law 280 was the essential (yet unspoken) basis for this Court’s decision in Colville." Id. at 911-12. The Supreme Court’s rejection of our distinction between Colville and this case indicates that Col-ville’s holding applies to this case.
. While Justice Stevens suggested that "a tribe’s sovereign immunity from actions seeking money damages does not necessarily extend to actions seeking equitable relief,” Oklahoma Tax Comm’n, 111 S.Ct. at 913 (Stevens, J., concurring), this view was not shared by any other member of the Court and was implicitly rejected in the majority opinion’s discussion of alternative remedies. See id. at 912.
The Tax Commission presents an additional argument that "the obligation to conduct its business lawfully can be imposed on the tribe by the court in equity.” While this argument is not entirely clear, to the extent that it asks us to adopt Justice Stevens’ position, we reject it. We do not rule out the possibility that affirmative equitable relief sought by the Tribe could be conditioned on the Tribe’s compliance with its legal obligations. See United States v. Wilson, 707 F.2d 304, 312 (8th Cir.1982) (per curiam on rehearing) (sovereign immunity not a bar to conditioning equitable relief sought by United States). See also Nicosia v. Sher, 239 F.2d 456, 457-58 (10th Cir.1956) (court’s conditional grant of equitable relief to plaintiff does not constitute an affirmative decree against plaintiff). However, the Tax Commission never sought conditions on the Tribe’s equitable relief; rather, the Tax Commission sought affirmative relief for itself. Because the Tax Commission failed to raise the argument below, we decline to consider it for the first time on appeal. See Singleton v. Wulff, 428 U.S. 106, 120, 96 S.Ct. 2868, 2877, 49 L.Ed.2d 826 (1976); Pell v. Azar Nut Co., Inc., 711 F.2d 949, 950 (10th Cir.1983).
