This appeal questions the power of Mississippi, as affected by the commerce clause, to impose a tax measured by gross receipts from the operation of a pipe line wholly within the state.

Appellant is a Delaware corporation which has qualified to do business in Mississippi as a foreign corporation. It owns and operates pipe lines which are used to transport oil from lease tanks in various oil fields in Mississippi to loading racks adjacent to railroads elsewhere in the state.1 From these racks the oil is pumped into railroad tank cars for shipment outside the state. If there are no tank cars available the oil is stored in tanks near the racks. But such delays in loading are usually of short duration and never exceed a week, according to appellant's uncontradicted statement. When delivered to appellant the oil is accompanied by shipping orders from the producer or owner directing that the oil be transported to out-of-state destinations. There are no refineries in Mississippi. There is no through bill of lading from the point of origin at the fields to the destination outside the state. Appellant ships the oil by rail as agent of the owner on bills of lading showing the owner as shipper, the appellant as agent of the shipper and indicating the destination specified in the shipping orders issue to appellant. Appellant is paid by the producer at the rate per barrel specific in its tariff2 from the gathering point to the rack and is paid an additional charge for loading the oil in the tank cars.

The chairman of the Mississippi State Tax Commission, appellee, levied a tax against appellant for the years 1944, 1945 and the first half of 1946, in the sum of $20,296.36, measured by appellant's receipts for transporti g oil from the lease tanks to the railroad loading platforms, pursuant to the following sections of the Mississippi Code, Miss. Code, 1942, Ann., tit. 40, c. 3, §§ 10105, 10109 (Supp. 1948), which provide:

'10105. There is hereby levied and shall be collected annual privilege taxes, measured by the amount or volume of business done, against the persons, on account of the business activities, and in the amounts to be determined by the application of rates against values, or gross income, or gross proceeds of sales, as the case may be, as follows (see sections following):'

'10109. * * * Upon every person engaging or continuing within this state in the business of operating a pipe line for transporting for compensation or hire from one point to another in this state oil or natural gas or artificial gas through pipes or conduits in this state, there is likewise hereby levied and shall be collected a tax, on account of the business engaged in, equal to two per cent of the gross income of the business. * * * 'There shall be excepted from the gross income used in determining the measure of the tax imposed in this section so much thereof as is derived from the business conducted in commerce between this state and other states of the United States, or between this state and foreign countries which the state of Mississippi is prohibited from taxing under the constitution of the United States of America. * * *'3

The State Tax Commission sustained the assessment. The trial court dismissed a declaration seeking review of the Commission's action. The Supreme Court of Mississippi affirmed that judgment, overruling appellant's contention that because the tax was levied on the privilege of conducting an interstate business and measured by gross receipts therefrom the tax could not be imposed without offending the commerce clause of the Federal Constitution. 203 Miss. 715, 35 So.2d 73.

The state supreme Court held that the operation of these pipe lines between points within the state was intrastate rather than interstate commerce, and that the tax was therefore 'merely on the privilege of operating a pipe line wholly within this State as a local activity. * * * a tax on the privilege of doing an intrastate business, and measured by a percent of gross income as a matter of convenience.' 203 Miss. at 715, 35 So.2d at page 81.

Appellant contends that operation of the pipe lines between points in Mississippi was in fact interstate commerce, and that the tax was construed by the Supreme Court of Mississippi to be a tax on the privilege of operating the pipe lines. From these premises, together with the major premise that no state can tax the privilege of engaging in interstate commerce, appellant concludes that the tax may not constitutionally be imposed.

We do not pause to consider whether the business of operating the intrastate pipe lines is interstate commerce for, even if we assume that it is, Mississippi has power to impose the tax involved in this case. Further, we do not find it necessary to dispute that the Supreme Court of Mississippi construed the statute as imposing a tax on the privilege of operating a pipe line wholly within the state, and not a tax solely upon the 'local activities of 'maintaining, keeping in repair, and otherwise in manning the facilities" situated in Mississippi, Memphis Gas Co. v. Stone, 335 U.S. 80, 92—93, 68 S.Ct. 1475, 1481, 92 L.Ed. 1832, or upon the gross receipts themselves, Central Greybound Lines v. Mealey, 334 U.S. 653, 68 S.Ct. 1260, 92 L.Ed. 1633. While we are of course bound by the constructio given a state statute by the highest court of the State,4 we are concerned with the practical operation of challenged state tax statutes, not with their descriptive labels.5

The statute is not invalidated by the commerce clause of the Federal Constitution merely because, unlike the statute attacked in Memphis Gas Co. v. Stone, supra, it imposes a 'direct' tax on the 'privilege' of engaging in interstate commerce.6 Any notions to the contrary should not have survived Maine v. Grand Trunk R. Co., 142 U.S. 217, 12 S.Ct. 121, 163, 35 L.Ed. 994, which flatly rules the case at bar. That case sustained a state statute which imposed upon an interstate railroad corporation 'an annual excise tax (measured by apportioned gross receipts), for the privilege of exercising its franchises in this State.'7 The Grand Trunk decision has been approved by this Court as recently as the other controlling case of Central Greyhound Lines v. Mealey, supra, 334 U.S. at page 658, 663, 68 S.Ct. at pages 1263, 1266, 92 L.Ed. 1633, in which the Court permitted New York to impose a tax on the gross receipts from the operation of an interstate bus line, provided that tax was apportioned according to mileage traveled within the state. The Mealey case is not distinguished by saying that it involved only a tax on gross receipts and not a tax on interstate commerce itself, for gross receipts taxes have long been regarded as 'direct' in cases which are supposed to support the proposition that 'direct' taxes on interstate commerce are invalid under the commerce clause.8

Since all the activities upon which the tax is imposed are carried on in Mississippi, there is no due process objection to the tax.9 The tax does not discriminate against interstate commerce in favor of competing intrastate commerce of like character.10 The nature of the subject of taxation makes apportionment unnecessary; there is no attempt to tax interstate activity carried on outside Missi sippi's borders. No other state can repeat the tax.11 For these reasons the commerce clause does not invalidate this tax.

The judgment is affirmed.

Affirmed.

Mr. Justice BURTON, concurring.

I join in the judgment of affirmance announced by the Court but do not join in the opinion rendered in support of it.

I concur in the judgment solely on the ground that the tax imposed by the State of Mississippi was a tax on the privilege of operating a pipe line for transporting oil in Mississippi in intrastate commerce and that, as such, it was a valid tax. The Supreme Court of Mississippi, in the case below, 203 Miss. 715, 35 So.2d 73, held that this tax had been authorized by a statute of that State, Miss. Code Ann. §§ 10105, 10109 (1942), and, for the reasons stated by that court, I believe that neither the statute nor the application of the tax in the present instance violated the Constitution of the United States. On that basis, there is no issue here as to the validity of a tax upon the privilege of transporting oil in Mississippi in interstate commerce.

Mr. Justice REED, with whom The CHIEF JUSTICE, Mr. Justice FRANKFURTER and Mr. Justice JACKSON joint dissenting.

Mississippi's effort to collect a privilege tax from this appellant for 'operating a pipe line' is upheld by this Court through two separately expressed theories. One, that the activities taxed are wholly intrastate and the other that even though the privilege taxed is for the carrying on of wholly intertate operations, such a privilege tax is permissible. As each theory may have effect far beyond this particular case, we think it advisable to state the reasons for our disagreement with both.

The tax which Mississippi demanded, and which appellant is now trying to recover, was computed only upon appellant's receipts as a common carrier for transporting oil from the lease tanks to the railroad loading platforms within the state. The Supreme Court of Mississippi upheld this tax on the ground that the activity producing the receipts was intra- rather than interstate commerce. At one point in its opinion, the Supreme Court of Mississippi said that the tax 'had been collected for the privilege of operating the pumping machinery and other pipe line equipment in the transportation of oil in the manner hereinbefore set forth * * *.' Interstate Oil Pipeline Co. v. Stone, 203 Miss. 715, 35 So.2d 73, 75. See an opinion of three members of this Court in Memphis Natural Gas Co. v. Stone, 335 U.S. 80, 68 S.Ct. 1475, 92 L.Ed. 1832. The section here in question gives no indication of such a purpose. It thus differs widely from the statute under consideration in the Memphis case with its definition of 'doing business.' See Stone v. Memphis Natural Gas Co., 201 Miss. 670, 29 So.2d 268, 270. Since this statute did not apply to pipe lines reaching across the state line, we conclude that the Supreme Court did not mean by these words to indicate that the privilege tax of § 10109 for 'operating a pipe line' was for the privilege of operating pumping machinery or other equipment as incidents apart from the flow of the interstate commerce. Cf. Coverdale v. Pipe Line Co., 303 U.S. 604, 58 S.Ct. 736, 82 L.Ed. 1043. Such an interpretation would be inconsistent with the nonliability for the tax of pipe lines, admittedly doing an interstate business. The tax, it said, was 'merely on the privilege of operating a pipe line wholly within this State as a local activity. * * * a tax on the privilege of doing an intrastate business, and measured by a percent of gross income as a matter of convenience.' 35 So.2d at page 81. The opinion emphasizes that in the view of the state court it is the intrastate character of the transportation that makes it permissible to charge the appellant a tax for the privilege of 'engaging * * * in the business of operating a pipe line.' § 10109.1 It considered taxability of the transportation in the light of Coe v. Town of Errol, 116 U.S. 517, 6 S.Ct. 475, 29 L.Ed. 715, and Champlain Realty Co. v. Town of Brattleboro, 260 U.S. 366, 43 S.Ct. 146, 67 L.Ed. 309, 25 A.L.R. 1195.

First. From the facts, §§ 10105 and 10109 of the statute, and the opinion of the Supreme Court of Mississippi, we believe that this statute was determined by the state to impose a privilege tax for carrying on the intrastate business of common carrier of oil in Mississippi and that the amount of that privilege tax was to be determined by a measure two percent of the gross income—of that intrastate business. Mississippi's interpretation of the meaning of its statute is binding on this Court.2 A federal question at once emerges—whether the shipment of the oil from the gathering point to the railroad loading racks, both points being in Mississippi, is intra- or interstate transportation. This we decide for ourselves from the undisputed facts in this record.3 Our first inquiry then must be as to whether the transportation of this oil, wholly within Mississippi from origin to railroad loading racks, is in interstate or intrastate commerce.4

In the absence of a rule written into the Constitution or enacted by Congress to determine what transportation is interstate and what intrastate, the courts have been required to determine the character of the transportation, case by case, as it became necessary to reach a judicial conclusion. It was decided years ago in The Daniel Ball, 10 Wall. 557, 19 L.Ed. 999, as to navigation on a waterway within a single state, disconnected from any other transportation system leading to or from other states, that the carriage of freight destined for or received from places outside the state of navigation was interstate commerce and made the boat subject to regulation by Congress.5 The wording of a judicial declaration of the precise line that marks the change from intrastate movement to interstate movement has been difficult. In Coe v. Town of Errol, 116 U.S. 517, 6 S.Ct. 475, 29 L.Ed. 715, a case that dealt with the taxability by New Hampshire of logs moved from her forests to a place of shipment in readiness for out-of-state transportation at the convenience of the owner, this Court held the logs taxable. The theory was that the first movement was preliminary to the interstate transportation,6 because of the deliberate detention to await a suitable time for shipment across a state line. Kelley v. Rhoads, 188 U.S. 1, 6, 23 S.Ct. 259, 261, 47 L.Ed. 359. But where there was no intentional delay, only they use of a 'harbor of refuge,' the interstate transportation by floatage began when the logs were put into the water. Champlain Realty Co. v. Town of Brattleboro, 260 U.S. 366, 43 S.Ct. 146, 67 L.Ed. 309, 25 A.L.R. 1195.7 Incidental dealings with the moving commodity do not break the interstate journey.8 Recently we have considered the effect of 'split' means of transportation as to whether the transportation was interstate. United States v. Capital Transit Co., 325 U.S. 357, 363, 65 S.Ct. 1176, 1179, 89 L.Ed. 1663. There a traveler went from the District of Columbia via streetcar or bus to a bus terminal and from there by a different bus to nearby Virginia. We held this to be interstate transportation.9

Comment should be made as to several precedents that might be thought contrary to the rather definite line marking the beginning of interstate commerce that appears in the above cases. These are the so-called casual or incidental movements of transportation wholly within a single state immediately preceding or following recognized interstate transportation. They were referred to in Coe v. Errol, supra, as haulage preliminary to consignment to interstate carriers. This involves the vehicles that carry passengers or freight to or from terminals in their interstate movement.10 An int rstate journey must have a beginning and an end. Common sense rejects an extension of the journey to the traveler's front door or the producer's farm or factory when no through order for carriage is in effect. The exact limits of interstate commerce in such fringe situations are uncertain.11

We are of the view, however, that the reach of interstate commerce goes to the delivery to Interstate, a common carrier, of the oil by the producer with his tender of shipment. That offer, when accepted, by its form is an order covering the amount of oil, origin and out-of-state destination, and the route and tariff under which shipment is made. The commodity has been placed in the stream of commerce and will cross state lines in the regular course of business. We have held that shipping instructions, given to a freight conductor on a common carrier prior to any movement, put a car into interstate commerce12 when the instructions were for shipment to an out-of-state destination after a preliminary transit between points in the state of loading. When a shipper delivers his commodity to a common carrier with instructions for billing by such carrier without purposeful delay via another or other common carriers to an out-of-state destination, we think interstate commerce has begun. Such an application of the commerce clause to transportation accords with that given to regulation of other phases of interstate commerce.13 The absence of a through bill of lading is not significant. It is true that the shipment might be diverted to an intrastate destination without crossing a state line but that cannot change the character of the commerce until such diversion order is given. The movement in commerce has begun by the order and the delivery and continues until the commodity is restored to the mass of property whithin a state by the termination of the transportation. See Joy Oil Co. v. State Tax Commission, 337 U.S. 286, 69 S.Ct. 1075.

Second. Mississippi determined that this tax was a privilege tax for carrying on the intrastate business of common carrier of oil in Mississippi, measured by a percentage of the income from that business. The preceding subdivision of this opinion expounds the arguments for our conclusion that all the business of appellant in operating a pipe line for transporting oil committed to move out-of-state from one point to another in Mississippi is interstate transportation. The statute in question was interpreted by Mississippi as laying a tax solely upon that business of transporting oil, not upon the 'local activities of 'maintaining, eeping in repair and otherwise in manning the facilities" such as are discussed in the opinions in the undecisive case of Memphis Natural Gas Co. v. Stone, 335 U.S. 80, at page 92—93, 68 S.Ct. 1475, 1482, 92 L.Ed. 1832.

An opinion has been filed in this case, asserting that the Mississippi tax could be collected from the petitioner notwithstanding that its entire business is interstate of 'maintaining, keeping in repair and otherwise in manning the facilities" transportation business, the privilege tax exacted by Mississippi is actually a privilege tax for carrying on the interstate business of common carrier of oil, measured by a percentage of the gross income from that business, apportioned so as to include only income derived from that portion of the interstate commerce carried on wholly in Mississippi. The gross receipts from interstate commerce are the costs of carriage from point of origin the field tanks—to the point of destination—the out-of-state refinery. As only that portion of the costs covering the carriage from origin to pipe-line loading racks, both points in Mississippi, is used to measure the privilege tax, it is clear that the interstate gross receipts are apportioned to carriage wholly within the state. Our issue at this point is whether a privilege tax for carrying on a wholly interstate transportation business measured by a fairly apportioned part of gross receipts for carriage in interstate commerce is constitutionally permissible.

Phrased in terms of a privilege for carrying on an interstate business, such a tax historically has been deemed unconstitutional. The cases abound in statements to the effect that the privilege of carrying on interstate commerce itself is immune from state taxation. This is because it is a privilege beyond the power of a state to grant. '* * * it is a right which every citizen of the United States (and every corporation) is entitled to exercise under the constitution and laws of the United States; * * *'. Crutcher v. Kentucky, 141 U.S. 47, 57, 11 S.Ct. 851, 853, 35 L.Ed. 649; International Textbook Co. v. Pigg, 217 U.S. 91, 30 S.Ct. 481, 54 L.Ed. 678, 27 L.R.A.,N.S., 493, 18 Ann.Cas. 1103. The cases hold not only that a state may not exact a tax as a condition precedent to the doing of interstate business, but also that it may not levy privilege, excise or franchise taxes on a foreign corporation for the privilege of carrying on or the actual doing of solely interstate business after its admission to the state.14 Ozark Pipe Line Corp. v. Monier, 266 U.S. 555, 45 S.Ct. 184, 69 L.Ed. 439; Alpha Portland Cement Co. v. Massachusetts, 268 U.S. 203, 45 S.Ct. 477, 69 L.Ed. 916, 44 A.L.R. 1219; Cf. Anglo-Chilean Nitrate Sales Corp. v. Alabama, 288 U.S. 218, 53 S.Ct. 373, 77 L.Ed. 710, in the light of Southern Natural Gas Corp. v. Alabama, 301 U.S. 148, 153, 57 S.Ct. 696, 698, 81 L.Ed. 970.15 The decisions in these cases were reached in spite of the fact that in each of them the tax sought to be levied was fairly measured according to the connections of the corporate taxpayer with the state. Thus in Ozark the tax was measured by a percentage of the capital stock and surplus of the corporation employed in business in the state, that proportion being deemed employed within the state 'that its property and assets in this state bears to all its property and assets wherever located' (266 U.S. 555, 45 S.Ct. 185); in Alpha by a percentage of the value of the 'corporate excess' employed within the commonwealth (determined as in Ozark) and a percentage of 'that part of its net income * * * which is derived from business carried on within the commonwealth' (268 U.S. 203, 45 S.Ct. 477) (also determined as in Ozark); in Anglo-Chilean by a percentage of capital employed in the state.

A recent pronouncement of this Court has recognized this limitation on state power. In Aero Mayflower Transit Co. v. Com'rs, 332 U.S. 495, 68 S.Ct. 167, 92 L.Ed. 99, we upheld a tax on motor carriers only after stressing the fact that the tax was 'affirmatively laid for the privilege of using the state's highways' and was not imposed upon 'the privilege of doing the interstate business.' 332 U.S. at p. 504, 68 S.Ct. at page 172, 92 L.Ed. 99. See Memphis Natural Gas Co. v. Stone, 335 U.S. 80, 88, note 10, 68 S.Ct. 1475, 1479, 92 L.Ed. 1832. Where the corporate taxpayer conducts intrastate as well as interstate business, a franchise privilege or excise tax on the former is of course permissible.16 We have frequently upheld such a tax although it was measured by property or receipts which were used in or attributable to interstate business.17

The growth of commerce that is carried on in more than one state has brought responsibilities to states other than the one in which the commerce may be said to have originated. Producers either directly or through middlemen and independent dealers distribute natural resources, agricultural and manufactured products on a nation-wide scale. Transportation runs across state lines. All states are called upon to give governmental services for this commerce—service that costs and should be paid for by those who profit from its maintenance. In the absence of congressional direction as to the taxation of interstate commerce, this Court has interpreted the commerce clause to permit state nondiscriminatory taxation for the use of state facilities, upon the property used in interstate commerce, upon production for commerce and upon net proceeds therefrom. Through such taxes, the states may exact payment for their protection and encouragement of commerce. Joseph v. Carter & Weekes Stevedoring Co., 330 U.S. 422, 429, 67 S.Ct. 815, 819, 91 L.Ed. 993, and cases cited. We have upheld a tax on gross receipts from interstate transportation when 'apportioned as to the mileage within the State.' Central Greyhound Lines v. Mealey, 334 U.S. 653, 663, 68 S.Ct. 1260, 1266, 92 L.Ed. 1633.18

Notwithstanding the wide latitude for taxation of incidents connected with interstate commerce, see Memphis Natural Gas Co. v. Stone, 335 U.S. 80, 68 S.Ct. 1475, 92 L.Ed. 1832, this Court has never interpreted the commerce clause to allow a state tax for the privilege of carrying on interstate commerce or one upon that commerce itself. Joseph v. Carter & Weekes Stevedoring Co., 330 U.S. 422, 67 S.Ct. 815, 91 L.Ed. 993. This is not because of the financial burden. Other taxes may equally burden the commerce. It is not because in transportation the same result cannot be obtained by levying a tax for intrastate activities measured by gross receipts appropriately apportioned to the activities in the state. It is because the commerce clause of the Constitution does not leave to the states any power to permit or refuse the carrying on of interstate commerce. It likewise bars a state from taxing the privilege of doing interstate commerce or the doing of interstate commerce, with or without fair apportionment even if not discriminatory.

Maine v. Grand Trunk R. Co., commented upon in note 18, is inapposite to the taxation here attempted by Mississippi. Interstate did a wholly interstate business. Grand Trunk, concerning a tax on the privilege of exercising a franchise in Maine, can only be reconciled with the later cases commented upon at note 15 if Grand Trunk did an intrastate as well as an interstate business. A state franchise tax for this is permissible. See notes 16 and 17, supra. The method of apportionment employed in the Grand Trunk case has had approval as recently as the Greyhound case, 334 U.S. at page 663, 68 S.Ct. 1260, 1266, 92 L.Ed. 1633. There was no approval of Grand Trunk in Greyhound as a precedent for a tax on the privilege of doing an interstate business. See 334 U.S. at p. 658, 68 S.Ct. at page 1263, 92 L.Ed. 1633.

Control of interstate commerce passed into the hands of Congress and thus welded the Federation into a Nation So long as states are forbidden to impose taxes upon interstate commerce or for the privilege of carrying it on, a toll cannot be exacted from interstate commerce even if a similar tax is borne by local commerce. So, interstate commerce is not susceptible to taxation, as such, and thus has been protected against exactions aimed at it, no matter how nondiscriminatory. It may be taxed only under enactments which likewise tax intrastate commerce for like intrastate activities. It gets no advantage over intrastate commerce from anything furnished by the state and pays the state nothing for what the state doesn't possess, that is, the power to allow interstate business within its borders.

All interstate commerce thus has free access to local markets subject only to nondiscriminatory taxes such as the tax on apportioned gross receipts from intrastate mileage as in Central Greyhound Lines v. Mealey, supra, or the tax on disconnected local incidents as discussed in the opinions in Memphis Natural Gas Co. v. Stone, supra, or in International Harvester Co. v. Evatt, supra, or American Manufacturing Co. v. City of St. Louis, 250 U.S. 459, 39 S.Ct. 522, 63 L.Ed. 1084. So long as a tax on the privilege of doing interstate business or a tax on the doing of that business is prohibited, interstate commerce remains free from state exactions levied on that commerce. Yet that commerce must bear like intrastate commerce the cost of those facilities or protections apart from the interstate commerce itself which the state furnishes or allows within its borders. Such as been and is the freedom that the commerce clause grants to those engaged in commerce between the states.

The judgment should be reversed.
