Opinion

O’ConNell, Acting Chief Judge,

delivered the opinion of the court:

These cases involve cross appeals from a decision and judgment of the United States Customs Court, Third Division, C. D. 1624, sustaining protests 171562-K and 180707-K and holding the three shipments there involved to be entitled to free entry as zirconium ore concentrates under paragraph 1719 of the Tariff Act of 1930, and overruling thirteen other protests and holding the shipments involved to be dutiable under paragraph 214 of the Act as earthy or mineral substances wholly or partly'manufactured.

The pertinent portions of the paragraphs in question are as follows: Tariff Act of 1930:

Par. 214. Earthy or mineral substances wholly or partly manufactured and articles, wares, and materials (crude or advanced in condition), composed wholly or in chief value of earthy or mineral substances, not specially provided for, whether susceptible of decoration or not, if not decorated in any manner, 30 per centum ad valorem; * * *.
[Rate reduced to 15% ad valorem by General Trade Agreement, T. D. 51802, effective January 1, 1948.]

(Free List):

Par. 1719. Minerals, crude, or not advanced in value or condition by refining or grinding, or by other process of manufacture, not specially provided for: * * *

Paragraph 1719, as amended by the Brazilian Trade Agreement, T. D. 48034:

Minerals, crude, or not advanced in value or condition by refining or grinding, or by other process of manufacture, not specially provided for: zirconium ores or concentrates.

Paragraph 1719, as amended by the General Trade Agreement, T. D. 51802, effective January 1, 1948:

Minerals, crude, or not advanced in value or condition by refining or grinding, or by other process of manufacture, not specially provided for: Lignite, Cornwall [51]*51stone, gravel, natural gas, nepheline syenite, beryllium ore, titanium ore (except ilmenite and ilmenite (sand), columbium or niobium ores or concentrates, tantalum ore, and zirconium ores or concentrates . . Free

As pointed out in the brief for the United States, entry 3721 in protest 151609-K and entry 05382 in protest 135863-K cover material not involved here, the former never having been included in the list of entries consolidated for trial and the latter having been abandoned at the commencement of the trial. As to those two entries, therefore, Appeal No. 4829 will be dismissed.

. The merchandise involved in these cases consists of alleged zirconium ore concentrates. Counsel for the parties entered into a stipulation of which the following portions are pertinent:

1. That with the exception of entries 1454 and 1585 in protest 180707-K and entry 2067 in protest 171562-K, all of the merchandise imported under the entries here involved was stabilized zirconium oxide produced in The Norton Company’s Canadian plant by a process such as or similar to the process described in U. S. Patent 2,535,526, applied for January 19, 1950, and issued December 26, 1950 to A. H. Ballard and D. W. Marshall, and assigned to The Norton Company, the importer of the instant merchandise. A certified copy of the aforesaid patent is attached hereto as Exhibit “A” and is made a part of this stipulation.
2. That with the exception of the aforementioned entries 1454 and 1585 in protest 180707-K a'nd entry 2067 in protest 171562-K, all the merchandise imported under the entries here involved contained approximately 3 to 5% of calcium oxide (lime) at the time of importation into the United States.
3. That the presence of the aforesaid amounts of calcium oxide (lime) in the imported merchandise was due to adding calcium oxide (lime) to the raw material in the Canadian plant of The Norton Company in addition to any calcium oxide (lime) which may have been present originally in said raw material.
* * * * * H? ❖ 5. That the crystal structure of such of the instant importations as contain approximately 5% of calcium oxide (lime), or 5% of magnesium oxide, is essentially cubic.
6. That the crystal structure of such of the instant importations as contain approximately 3% of calcium oxide (lime), or 3% of magnesium oxide, is approximately 50% monoclinic and 50% cubic.
7. That the crystal structure of such of the instant importations as contain no added calcium oxide (lime), or added magnesium, is essentially monoclinic.
12. That “Zircon Sand” is a common name for a natural physical state of zirconium silicate (zircon). It may contain some zirconium oxide (baddeleyite) as such, in small amount, some free silica, in small amount, and other impurities.
15. That “Zirconium silicate” is a definite compound containing no free zirconium oxide as such, and no free silicon dioxide (silica) as such.
22. That an ore of an element may occur in nature in the form of one or more chemical compounds.
23. That an ore may occur in various states of purity in nature.

[52]*52With respect to the three entries in the present case to which no’ lime was added, the importer’s witness Upper gave the following testimony:

Q. Referring to the product which was the subject of C. D. 1297, [a case-incorporated in the record] and concerning which you testified in that case, I ask you whether that product is the same product or similar product to the three entries in the present case which have no added lime? A. They are identical.
Q. Was the process the same in Chippawa? A. The process was the same.
% tfc ‡ *
Q. Now, referring to the remaining entries involved in this case, that is»' those to which lime was added, was that produced in the same manner except for the addition of the lime as the product in C. D. 1297? A. Exactly.

From that testimony and the stipulation it follows that the merchandise in all the entires here involved was produced by the process-of patent No. 2,535,526, except that in the three entries involved in' Appeal No. 4828 no lime was added.

The .process of patent No. 2,535,526 comprises fusing in an electric arc furnace a mixture of zirconium ore, carbon, iron borings and lime. As the result of this procedure the oxides of silicon and zirconium in the ore are separated from each other, the silicon oxide (silica) is reduced by the carbon to produce free silicon and this-silicon combines with the iron to form a ferro-silicon which sinks to the bottom of the furnace and is readily separated from the other materials. The inclusion of the lime, which is referred to as a stabilizing agent, results in the production of a zirconium oxide (zirconia) which, instead of the natural monoclinic crystal structure has a crystal structure varying from 50% monoclinic and 50% cubic to 100% cubic, depending on the amount of lime used. The patent alleges that the so-called stabilized zirconia, having the cubic crystal structure is superior to that having a monoclinic structure.

Appeal No. 4828

The merchandise involved in Appeal No. 4828 was produced by the process above-described, without the addition of lime.
