HARRIS, Judge.

The question involves a tax on the purchase of machinery. Orders were placed from out-of-state vendors prior to the effective date of a sales and use tax increase; delivery was made after the increase. The district court determined that the transaction was taxable at the increased rate. We reverse and remand.

The Iowa legislature increased the Iowa sales and use tax from three percent to four percent, effective March 1, 1983. Plaintiff Caterpillar ordered several large machines from vendors located outside of Iowa for its Davenport, Iowa, manufacturing plant. Although the orders were placed in 1981 and 1982, the machinery was not delivered until after March 1, 1983.

The Iowa department of revenue and finance (the department) determined that the transaction should be taxed at the four percent rate. Caterpillar paid accordingly under protest and filed for a refund of $115,408.96, the one percent difference. After unsuccessfully exhausting its administrative remedies, Caterpillar brought this action for judicial review. This is an appeal from a district court ruling affirming the department's decision.

The department adopted "transition provisions" meant to be used in determining whether the three percent or four percent tax rate was applicable. Department rule 701 I.A.C. 14.3 focused on the time of contract for sales tax purposes, and on the time of delivery for use taxes. It provided:

1. The four percent sales tax rate applies to sales of tangible personal property where the sales contract is entered into on or after March 1, 1983. Jones v. Gordy, 169 Md. 173, 180 Atl. 272 (1935).

EXAMPLE: A enters into a sales contract with B to purchase a tractor from B. This contract (offer and acceptance) is made on February 28, 1983. The tractor is delivered to A on March 3, 1983, and A pays B on March 10, 1983. Since the contract was entered into prior to March 1, 1983, the sales tax in this example is on the three percent rate.

....

2. The four percent use tax rate applies to the use of tangible personal property in this state where the first taxable use occurs on or after March 1, 1983.

EXAMPLE: On January 24, 1983, A and B enter into a sales contract outside of Iowa for the purchase by A from B of a machine. The machine is not delivered until March 16, 1983. The delivery to A constitutes a use by A in Iowa for the first time of the machine. Under these circumstances the machine is subject to the four percent rate since the tax rate in effect at the time of use (March 16, 1983) governs where the property is purchased outside of Iowa. See City of Ames v. State Tax Comm'n, 246 Iowa 1016, 71 N.W.2d 15 (1955).

The example applies a three percent sales tax to contracts entered before the effective date of a rate change when an Iowa business makes the sale, even when delivery occurs after the effective date. A four percent use tax applies, however, when a sales contract with a non-Iowa business is entered into before the effective date of the rate increase, but delivery occurs thereafter. The department concedes that rule 14.3 is at least in part invalid because the first example under rule 14.3(1) (sales tax) is inconsistent with our subsequent holding in Sturtz v. Iowa Department of Revenue, 373 N.W.2d 131, 134 (Iowa 1985) (delivery in Iowa triggers sales tax).

I. A state may not impose a tax that discriminates against interstate commerce by providing a direct commercial advantage to local businesses. Boston Stock Exch. v. State Tax Comm'n, 429 U.S. 318, 329, 97 S.Ct. 599, 607, 50 L.Ed.2d 514, 524 (1977) (quoting Northwestern States Portland Cement Co. v. Minnesota, 358 U.S. 450, 458, 79 S.Ct. 357, 362, 3 L.Ed.2d 421, 427 (1959)). State legislation designed to further legitimate state interests and applied without discriminating against interstate commerce, however, is permissible, even though it may affect interstate commerce. Hearst v. Iowa Dep't of Revenue and Fin., 461 N.W.2d 295, 307 (Iowa 1990). As long as class distinctions are not based on any in-state or out-of-state criteria, the commerce clause is not violated. Id. at 308 (citing Commonwealth Edison Co. v. Montana, 453 U.S. 609, 617, 101 S.Ct. 2946, 2953, 69 L.Ed.2d 884, 895 (1981); Exxon Corp. v. Governor of Maryland, 437 U.S. 117, 126, 98 S.Ct. 2207, 2214, 57 L.Ed.2d 91, 100 (1978); Moorman Mfg. Co. v. Bair, 437 U.S. 267, 277 n. 12, 98 S.Ct. 2340, 2346 n. 12, 57 L.Ed.2d 197, 207 n. 12 (1978)). Under these principles sales and use taxes must impose the same burden and this the department rule failed to do.

Having conceded the...
