delivered the opinion of the Court.
A statute of Washington taxing the use of chattels in that state is assailed in this suit as a violation of the commerce clause (Constitution of the United States, Article I, § 8) in so far as the tax is applicable to chattels purchased in another state and used in Washington thereafter.

Plaintiffs (appellees in this court) are engaged either as contractors or as subcontractors in the construction of the Grand Coulee Dam on the Columbia River. In the performance of that work they have brought into the state of Washington machinery, materials and supplies, such as locomotives, cars, conveyors, pumps, and trestle steel, which were bought at retail in other states. The cost of all the articles with transportation expenses added was $921,189.34. Defendants, the Tax Commission of Washington (appellants in this court) gave notice that plaintiffs had become subject through the use of this property to a tax of $18,423.78, two per cent of the cost, and made demand for payment. A District Court of three judges, organized in accordance with § 266 of the Judicial Code (28 U. S. C. § 380), adjudged the statute void upon its face, and granted an interlocutory injunction, one judge dissenting.
Chapter 180 of the Laws of Washington for the year 1935, consisting of twenty titles, lays a multitude of excise taxes on occupations and activities. Only two' of these taxes are important for the purposes of the case at hand, the "tax on retail sales,” imposed by Title III, and the "compensating tax,” imposed by Title IY on the privilege of use. Title III provides that after May 1, 1935, every retail sale in Washington, with a few enumerated exceptions, 1 shall be subject to a tax of 2% of *580 the selling price. Title IV, with the heading “compensating tax,” provides (§§ 31, 35) that there shall be collected from every person in the state “a tax or excise for the privilege of using within this state any article of tangible personal property purchased subsequent to April 30, 1935,” at the rate of 2% of the purchase price, including in such price the cost of transportation from the place where the article was purchased. If those provisions stood alone, they would mean that retail buyers within the state would have to pay a double tax, 2% upon the sale and 2% upon the use. Relief from such a burden is provided in another section (§ 32) which qualifies the use tax by allowing four exceptions. Only two of these exceptions (b and c) call for mention at this time.* 2 Subdivision (b) provides that the use tax shall not be laid unless the property has been bought at retail. Subdivision (c) provides that the tax shall not *581 apply to the “use of any article of tangible personal property the sale or use of which has already been subjected to a' tax equal to or in excess of that imposed by this title whether under the laws of this state or of some other state of the United States.” If the rate of such other tax is less than 2%, the exemption is not to be complete (§ 33), but in such circumstances the rate is to be measured by the difference.
The plan embodied in these provisions is neither hidden nor uncertain. A use tax is never payable where the user has acquired property by retail purchase in the state of Washington, except in the rare instances in which retail purchases in Washington are not subjected to a sales tax. On the other hand, a use tax is always payable where the user has acquired property by retail purchase in or from another state, unless he has paid a sales or use tax elsewhere before bringing it to Washington. The tax presupposes everywhere a retail purchase by the user before the time of use. If he has manufactured the chattel for himself, or has received it from the manufacturer as a legacy- or gift, he is exempt from the use tax, whether title was acquired in Washington or elsewhere. The practical effect of a system .thus conditioned is readily perceived. One of its effects must be that retail sellers in Washington will be helped to compete upon terms of equality with retail dealers in other states who are exempt from a sales tax or any corresponding burden. Another effect, or at least another tendency, must be to avoid the likelihood of a drain upon the revenues of the state, buyers being no longer tempted to place their orders in other states in the effort to escape payment of the tax on local sales. Do these consequences which must have been foreseen, necessitate a holding that the tax upon the use is either a tax upon the operations of interstate commerce or a discrimination against such commerce obstructing or burdening it unlawfully?
*582 1. The tax is not upon the operations of interstate commerce, but upon the privilege of use after commerce is at an end.
Things acquired or transported in interstate commerce may be subjected to a property tax, non-discriminatory in its operation, when they have become part of the common mass of property within the state of destination.

v.
Pennsylvania,
The case before us does not call for approval or disapproval of the definition of use or enjoyment in the rules of the Commission. Those rules inform us that “property is put to use by the first act after delivery is,completed within the state by which the article purchased is actually used or is made available for use with intent actually to use the same within the state. The term 'made available for use’ means and includes the exercise of any right or power over tangible personal property preparatory to actual use within the state, such as keeping, storing, withdrawing from storage, moving, installing or performing any act by which dominion or control over the property is assumed by the purchaser.” A tax upon a use so closely connected with delivery as to be in substance a part thereof might be subject to the same objections that would be applicable to a tax upon the sale itself. If the rules are too drastic in that respect or others, the defect is unimportant in relation to this case. Here the machinery and other chattels subjected to the tax have had continuous use in Washington long after the time when delivery was over. The plaintiffs are not the champions of any rights except their own.
2. The tax upon the use after the property is at rest is not so measured or conditioned as to hamper the transactions of interstate commerce or discriminate against them.
Equality is the theme that runs through all the sections of the statute. There shall be a tax upon the use, but sub *584 ject to an offset if another use or sales tax has been paid for the same thing. This is true where the offsetting tax became payable to Washington by reason of purchase or use within the state. It is true in exactly the same measure where the offsetting tax has been paid to another state by reason of use or purchase there. No one who uses property in Washington after buying it at retail is to be exempt from a tax upon the privilege of enjoyment except to the extent that he has paid a use or sales tax somewhere. Every one who has paid a use or sales tax anywhere, or, more accurately, in any state, is to that extent to be exempt from the payment of another tax in Washington.
When the account is made up, the stranger from afar is subject to no greater burdens as a consequence of ownership than the dweller within the gates. The one pays upon one activity or incident, and the other upon another, but the sum is the same when the reckoning is closed. Equality exists when the chattel subjected to the use tax is bought in another state and then carried into Washington. It exists when the imported chattel is shipped from the state of origin under an order received directly from the state of destination. In each situation the burden borne by the owner is balanced by an equal burden where the sale is strictly local. “There is no demand in . . . [the] Constitution that the State shall put its requirements in any one statute. It may distribute them as it sees fit, if the result, taken in its totality, is within the State’s constitutional power.”

v.
G. A. F. Seelig, Inc.,
We are told that a tax upon the use, even though not unlawful by force of its effects alone, is vitiated by the motives that led to its adoption. These motives cause it to be stigmatized as equivalent to a protective tariff. But motives alone will seldom, if ever, invalidate a tax that apart from its motives would be recognized as lawful.
Magnano Co.
v.
Hamilton,
Finally, there is argument that the tax now in question, though in form upon the use, was in fact upon the foreign sale, and not upon the use at all, the form being a subterfuge. The supposed basis for that argument is a reading of the statute whereby the use shall not be taxable if the chattel was manufactured by the user or received as a legacy or acquired in any way except through the medium of purchase, and a retail one at that. But the fact that the legislature has chosen to lay a tax upon the use of chattels that have been bought does not make the tax upon the use a tax upon the sale. One could argue with as much reason that there would be a tax upon the sale if a property tax were limited to chattels so acquired. A legislature has a wide range of choice in classifying and limiting the subjects of taxation.
