OPINION
In this case we must decide whether Thurston County, Washington, may impose an
ad valorem
tax on logs stored at the Port of Olympia awaiting ships for transportation to Japan. The district court held that the logs were in the process of exportation and that the tax was, therefore, a state imposed duty on exports prohibited by Article I, Section 10, Clause 2, of the United States Constitution.

Following submission of the ap
*606
peal, we vacated our action pending the Supreme Court’s disposition of Kosydar v. National Cash Register Co.,
The parties submitted the case on stipulated facts. Sumitomo is a foreign corporation which imports logs to Japan. Each summer it takes orders from its Japanese customers and buys logs to meet demand. 2 The logs in issue were purchased in Washington state and delivered to Sumitomo f. o. b. the Port of Olympia. The seller performed all sorting, scaling, loading, and unloading of the logs except they were not sorted by length at delivery. The logs were then stored in a storage yard at the port awaiting ships to take them to Japan.
In order to load ships efficiently as they arrived at the port, Sumitomo continuously had a supply of logs on hand in the storage area. The average turnover was 45 days, although specific logs may have stayed in the storage area for a shorter or longer period of time. All logs were stored only as long as necessary to await arrival of a ship upon which they could be loaded. Sumitomo sold no logs domestically, and the financial arrangements, the company’s past practices, and the type of logs purchased indicated with reasonable certainty that the logs would be exported.
The issue on appeal is whether the county may levy an ad valorem tax on logs stored by Sumitomo at the Port of Olympia awaiting shipment. We hold that it may.
Although Article I, Section 10, Clause 2, of the Constitution prohibits a state from imposing a duty on exports, property within the state is not exempt from taxation solely because it may be exported in the future.
See, e. g.,
Empresa Siderurgica, S.A. v. Merced County,
Sumitomo’s position must be rejected as it is contrary to the holding in Coe v. Errol,
Applying the
Coe
standard to Sumi-tomo’s logs, it is clear that they had not yet become “exports” immune from local taxation when the
ad valorem
tax was levied. In
Coe
the Court considered two collections of logs. The first had been cut in Maine and floated down the An-droscoggin River enroute to another lo
*607
cation in Maine. The course of the River took the logs through the town of Errol, New Hampshire, where they were delayed by low water. The Court held that these logs were merely passing through New Hampshire and were already in the course of commercial transportation. Therefore, they enjoyed constitutional protection from taxation.
The second crop of logs had been cut in New Hampshire and brought to Errol to be floated out of state. The logs were floated in and placed on the banks of a tributary of the Androscoggin River awaiting commencement of the journey. The Court held that the logs had not yet begun their journey and were not constitutionally protected:
There must be a point of time when [the logs] cease to be governed exclusively by the domestic law and begin to be governed and protected by the national law of commercial regulation, and that moment seems to us to be a legitimate one for this purpose, in which they commence their final movement for transportation from the State of their origin to that of their destination. When the products of the farm or the forest are collected and brought in from the surrounding country to a town or station serving as an entrepot for that particular region, whether on a river or a line of railroad, such products are not yet exports, nor are they in process of exportation, nor is exportation begun until they are committed to the common carrier for transportation out of the State to State of their destination, or have started on their ultimate passage to that State.'
Sumitomo’s logs are in the same position as the second collection of logs in
Coe.
They were cut in the forests of Washington state and taken to an entrepot within that state, the port of Olympia, to await shipment out of the state. They had neither been committed to a common carrier for export, A. G. Spalding & Bros. v. Edwards,
Sumitomo makes two counter arguments to support its position. First, it argues that the quality of the logs, the contractual and financial arrangements covering them, and Sumitomo’s past practices indicated with reasonable certainty that the logs would be exported. Thus, there was no reasonable probability that the logs would be di *608 verted to the domestic market after escaping taxation.
There is some case law support for the conclusion that certainty of exportation is a criterion for determining whether exportation has begun. In
Richfield
the Court concluded that oil became an “export” when loaded on a ship bound for a foreign destination, even though the ship was not a common carrier. The Court reasoned that the theoretical possibility of diversion to the local market should be overlooked because it was reasonably certain that the oil was going to be delivered outside the United States.
The reliance on the certainty of export in
Richfield
was, however, used merely to excuse the fact that the ship was not a common carrier. Certainty of export evidenced by financial and contractual relationships does not by itself render goods “exports” before the commencement of their journey abroad. Empresa Siderurgica, S.A. v. Merced County,

at 156-157,
Second, Sumitomo argues that Carson Petroleum Co. v. Vial,
Sumitomo argues that, as with the oil in Carson, its logs were being stored at the port only to await the arrival of a ship to transport them to Japan. This is true. But unlike the oil in Carson, Sumitomo’s logs had not been traveling interstate prior to their storage at the Port of Olympia. Carson involved the interruption of an interstate/international journey that had admittedly begun long before the oil reached New Orleans. The Court held merely that when such a journey is interrupted by a geographically necessary change in transportation modes, reasonable delays and inventories to facilitate that change do not cause the goods to cease being “ex *609 ports” or “goods in interstate commerce,” Thus, Carson involved a situation similar to the first group of logs in Coe which were delayed by low water during their journey through New Hampshire.
Sumitomo’s logs, on the other hand, were not interrupted on a journey through Washington from another state to a foreign destination. They were, like the second group of logs in Coe, products of Washington taken to an entrepot from surrounding areas within the state. 7 Thus, under the holding of Coe they had not yet become “exports” falling under the protection of Article I, Section 10, Clause 2.
It is true that Carson did not explicitly distinguish the oil delayed at the port from the logs collected at the entrepot in Coe on the basis that the former had begun its journey in another state. Thus, it is not unreasonable for Sumito-mo to contend that Carson casts doubt on the validity of Coe. But since Coe has been explicitly approved and its standard relied on in Richfield, Empresa Siderúr-gica, and most recently, in Kosydar— all decided after Carson — Sumitomo’s interpretation of Carson must be rejected.
The logs upon which Thurston County levied its ad valorem, tax had not yet become “exports” entitled to the protection of Article I, Section 10, Clause 2, of the United States Constitution. The judgment of the district court is reversed, and the case is remanded for entry of judgment in favor of appellant county.
Notes
. No state shall, without the Consent of the Congress, lay any Imposts or Duties on Imports or Exports, except what may be absolutely necessary for executing its inspection Laws ....
. Sumitomo’s purchases exceeded orders by 10%, but this was merely “to account for those unavoidable problems which necessarily arise when dealing with a semi-perishable commodity.”
. Although Spalding and Richfield involved sales taxes, each result explicitly depended on the point at which the goods commenced their journey and thereby became “exports.”
. Noting that the Court had adhered to the basic principle of Coe v. Errol for the nearly 90 years since that case was decided, Kosydar v. National Cash Register Co.,

It may be said that insistence upon an actual movement into the stream of export in the case at hand represents an overly wooden or mechanistic application of the Coe doctrine. This is an instance, however, where we believe that simplicity has its virtues. The Court recognized long ago that even if it is not an easy matter to set down a rule determining the moment in time when articles obtain the protection of the Import-Export Clause, “it is highly important, both to the shipper and to the State, that it should be clearly defined so as to avoid all ambiguity or question.” Coe, supra,116 U.S. at 526 ,6 S.Ct. at 478 .

. The likelihood of eventual exportation was probably even greater in Kosydar than under the facts presented in this case. The taxpayer in Kosydar -was engaged in the manufacture of business machines, and its wholly separate international division did not commence manufacture until actual receipt of foreign orders. The machines produced were designed for the peculiar foreign market, using unique keyboards, characters, and decimal point placement, and quite often were designed to utilize the electric supply of the foreign country which often differs from that in standard use in this country. Each machine so constructed was eventually exported, and none ever re-entered the domestic market.
. Although we rely on the difference between out-of-state and in-state goods delayed at the water’s edge, we do not hold that this distinction is necessarily conclusive in all factual situations. Specifically, we infer no holding concerning the situation where goods are consigned to a common carrier within a state for out-of-state shipment but are delayed at the interface of two modes of transportation prior to leaving the state while still within the control of the common carrier.
