United States; used to line electrical furnaces; refractory brick; 8545.90.40; used for electrical purposes; Additional U.S. Rule of Interpretation 1(a); principal use

Dear District Director:

This pertains to Protest 2704-93-100094, concerning the tariff classification of graphite cathode blocks under the Harmonized Tariff Schedule of the United States (HTSUS). Information presented in additional submissions dated June 9, October 5, 1993, January 21, and June 9, 1994, and at a meeting on May 2, 1994, were considered in rendering this decision.

FACTS:

The articles under consideration are graphite cathode blocks, also known as "bottom blocks", which are used to line the bottom of aluminum reduction furnaces known as "cells" or "pots". The graphite cathode blocks are made from petroleum coke and pitch which is formed into blocks and then baked. They are also subjected to a second furnacing operation, known as "graphitization", whereby the blocks are heated to temperatures of 2500 degrees Celsius for an extended period of time. The protestant states that the graphite cathode blocks contain electrical characteristics similar to the carbon blocks in Eastalco Aluminum Co. v. United States, 10 CIT 622 (1986), and function in exactly the same manner as those carbon blocks in that they act as a cathode for the initial start-up phase (12 to 24 hours), after which the molten aluminum pad becomes the cathode.

The entries of the graphite cathode blocks were liquidated on February 5, and 12, 1993, under subheading 8545.90.40, HTSUS, as other articles of graphite or other carbon, of a kind used for electrical purposes. In a protest timely filed on April 29, 1993, the protestant contends that the graphite cathode blocks are provided for under subheading 6902.90.10, HTSUS, as other refractory bricks, or, alternatively, under subheading 8514.90.00, HTSUS, as parts of industrial or laboratory electric furnaces and ovens.

The competing subheadings are as follows:

6902.90.10 Refractory bricks, blocks, tiles, and similar refractory ceramic constructional goods, other than those of siliceous fossil meals or similar siliceous earths...Other...Bricks....

8514.90.00 Industrial or laboratory electric (including induction or dielectric) furnaces and ovens; other industrial or laboratory induction or dielectric heating equipment; parts thereof...Parts.

8545.90.40 Carbon electrodes, carbon brushes, lamp carbons, battery carbons and other articles of graphite or other carbon, with or without metal, of a kind used for electrical purposes...Other...Other.

ISSUE:

Are the graphite cathode blocks classified under subheading 6902.90.10, HTSUS, as other refractory bricks, or subheading 8514.90.00, HTSUS, as parts of industrial or laboratory electric furnaces and ovens, or subheading 8545.90.40, HTSUS, as other articles of graphite or other carbon, of a kind used for electrical purposes.

LAW AND ANALYSIS:

The classification of merchandise under the HTSUS is governed by the General Rules of Interpretation (GRIs). GRI 1, HTSUS, states in part that "for legal purposes, classification shall be determined according to the terms of the headings and any relative section or chapter notes...."

To be classified under subheading 6902.90.10, HTSUS, the graphite cathode blocks must meet the definition of ceramic in Note 1, and Additional U.S. Note 1(a), HTSUS. Note 1, Chapter 69, HTSUS, states that chapter 69, HTSUS, "...applies only to ceramic products which have been fired after shaping." Additional U.S. Note 1(a), Chapter 69, HTSUS, states that:

For the purposes of this chapter, a "ceramic article" is a shaped article having a glazed or unglazed body of crystalline or substantially crystalline structure, the body of which is composed essentially of inorganic nonmetallic substances and is formed and subsequently hardened by such heat treatment that the body, if reheated to pyrometric cone 020, would not become more dense, harder, or less porous, but does not include any glass articles (emphasis in original).

The issue of "substantially crystalline" in regards to the tariff classification of carbon blocks has been addressed by the U.S. Court of International Trade in Eastalco Aluminum Co. v. United States, 10 CIT 622 (1986) ("Eastalco I"). The articles involved in Eastalco I were side and bottom carbon blocks used to line an aluminum reduction cell in which aluminum was produced through an electrolytic process. The carbon blocks were designed to withstand extreme stress, heat, and corrosion during the production of aluminum. For a period of 12 to 24 hours during the start-up phase of the cell, the carbon bottom blocks act as a cathode. Cathodic action is necessary for proper start-up and to ensure the longevity of the cell. After the start-up phase and after molten aluminum is added, a molten aluminum pad becomes the cathode. For the duration of the life of the cell, approximately 1500 days, the carbon bottom blocks continue to function in their refractory capacity. The carbon corner and side blocks do not function cathodically except in an incidental manner or under abnormal conditions.

The subject merchandise of Eastalco I was classified by Customs in item 517.61, Tariff Schedules of the United States (TSUS), as electrodes in part of carbon or graphite, for electric furnace or electrolytic purposes and was claimed classifiable by Eastalco in item 531.27, TSUS, as refractory brick. The Government counterclaimed for classification in item 517.91, TSUS, as articles not specifically provided for, of carbon or graphite, or in item 535.14, TSUS, as other ceramic electrical ware.

The Court held that the carbon blocks were not eo nomine or chief use electrodes in part of carbon or graphite, for electric furnace or electrolytic purposes classifiable in item 517.61, TSUS. The Court found that the side carbon blocks were not intended to be used as electrodes and that both the side and bottom carbon blocks had a vital use as heat insulators and refractories which extended for their entire lives. Additionally, the Court found that the bottom carbon blocks' heat insulating and refractory functions were longer lasting than the electrode function. The carbon bottom blocks acted as an electrode for only 12 to 24 hours, i.e., less than 1% of the cell's life, given the average cell-life of 1500 days. The Court then concluded that the carbon blocks had not been shown to be classifiable as refractory brick in item 531.27, TSUS, and remanded the matter to Customs for further consideration.

In Eastalco Aluminum Co. v. United States, 13 CIT 864, 726 F. Supp. 1342 (CIT 1989) ("Eastalco II"), the Court stated that Customs had been instructed to address two issues:

1. whether the electrical conductivity and resistivity of the bottom block made it something other than refractory brick, item 531.27, TSUS....

2. whether the bottom and side blocks are "ceramic articles."

On remand, Customs classified the carbon blocks in item 517.91, TSUS, as articles not specifically provided for, of carbon or graphite.

The principal issue as to whether the bottom and side blocks were ceramic articles dealt with whether the articles were "substantially crystalline." After hearing evidence from both parties, the Court determined that the "substantially crystalline" arguments presented were equipoise. "Plaintiff's expert witness had testified to the effect that the block was more than 50 percent crystalline. Defendant's expert witness had indicated that it was less than 50 percent crystalline." Eastalco II at 865. However, the testimony did indicate that quantitative testing could be established. A testing method was agreed upon by both parties, implemented and the Court stated:

At the risk of oversimplication, the court believes the quantitative test reveals that the block has substantially less than fifty percent crystalline content.

Id.

The Plaintiff argued that the 50 percent standard was not the appropriate gauge of substantial crystallinity. However, the Court stated that:

While fifty percent may not be the appropriate dividing line on the issue of what constitutes substantial crystallinity, as that term is used in the tariff schedules, the quantitative test has shown that a very low level of crystallinity is involved and that plaintiff's witness' earlier evaluation was not as accurate as that of defendant's expert.

Id.

The Court concluded that the carbon blocks did not meet the definition of ceramic and, therefore, could not be classified as refractory brick in item 531.27, TSUS. The carbon blocks were, therefore, classified in item 517.91, TSUS, as articles not specifically provided for, of carbon or graphite. Additionally, we note that as to the first remand issue, the Court stated in a footnote that:

This issue need not be resolved finally because of the court's finding on the second issue, although the court was of the opinion after hearing further evidence that the electrical properties, by themselves, did not make the refractory brick designation inappropriate.

Id.

In affirming the CIT in Eastalco II, the Court in Eastalco Aluminum Co. v. United States, 916 F.2d 1568 (Fed. Cir. 1990) ("Eastalco III"), noted that the test results of the carbon block in Eastalco II indicated a crystalline content of 5 percent (plus or minus 1 percent). Eastalco contended that the CIT erred in concluding that "substantially crystalline" referred to a quantitative crystalline content. Eastalco maintained instead that the words "substantially crystalline" only require that the blocks have acquired some crystalline carbon ordering.

The Court rejected this argument and affirmed the CIT's finding that the test of whether a material is "substantially crystalline" is a quantitative one. In resolving this issue, the Court referred to the legislative history involving ceramic articles. The Court noted that Congress limited ceramic articles to items that were substantially crystalline and excluded certain silica-derived substances. The dividing line as expressly stated in the legislative history is "whether they have 'small quantities' or 'sufficient amounts' of crystalline structure, the adverbial adjective, 'substantially,' was meant to import a quantitative limitation." Eastalco III at 1571. Furthermore, the Court stated that the legislative history indicates that the amount envisioned for a ceramic article was to exceed trivial percentages such as that found in opalescent glass. Therefore, the Court stated that since the uncontested evidence indicates that the carbon blocks have at most a 6 percent crystalline content, they are not "substantially crystalline" and cannot be classified as a refractory brick in item 531.27, TSUS.

Congress has indicated that earlier tariff decisions must not be disregarded in applying the HTSUS. The conference report to the Omnibus Trade Bill of 1988, stated that "on a case-by-case basis prior decisions should be considered instructive in interpreting the HTS[US], particularly where the nomenclature previously interpreted in those decisions remain unchanged and no dissimilar interpretation is required by the text of the HTS[US]." H. Rep. No. 100-576, 100th cong., 2d Sess. 548, 550 (1988). Since the subject articles at issue in the Eastalco cases and the instant case are similar, if not identical, and the nomenclature of the TSUS and HTSUS is similar, we find that the Eastalco cases are instructive.

In order for the graphite cathode blocks to be classified under subheading 6902.90.00, HTSUS, they must be "substantially crystalline." The Courts in Eastalco II and Eastalco III determined that a low amount of crystalline content, i.e., 6%, was not enough to meet the requirement of "substantially crystalline." We are of the opinion that none of the Courts in the Eastalco cases determined the exact percentage of crystallinity necessary for an article to meet the definition of "ceramic" for tariff classification purposes. The only comments made regarding this issue are found in Eastalco II at 865:

While fifty percent may not be the appropriate dividing line on the issue of what constitutes substantial crystallinity, as that term is used in the tariff schedules, the quantitative test has shown that a very low level of crystallinity is involved and that plaintiff's witness' earlier evaluation was not as accurate as that of defendant's expert.

At the risk of oversimplication, the court believes the quantitative test reveals that the block has substantially less than fifty percent crystalline content.

While the Court mentions a 50% figure, this percentage figure was introduced by the parties to the case. We are of the opinion that the Courts reference to 50% in Eastalco II is mere dictum as it was not necessary for the Court to address the 50% bench mark in rendering its final classification decision.

The Eastalco II Court did find that defendant's expert was more accurate in its evaluation of the carbon block. An examination of the "DIRECT TESTIMONY of DR. VERNON BURDICK", defendant's witness, who was called to give his opinion on ceramics, reveals that he recommends "[s]eventy or more percent crystallinity in ceramics is required in order that the ceramic articles attain the desired properties of high mechanical, thermal and chemical integrity that they are known for." Id at 4. Once again, we note that none of the Eastalco Courts adopted the 70% figure presented by the defendant.

Additionally, we note that protestant's counsel has submitted a statement from Dr. Peter Thrower, who was the expert selected by both the plaintiff and defendant in Eastalco II to perform the agreed upon testing procedure. Dr. Thrower opines that a "substantially crystalline" standard of 70% or more is indefensible. He states that:

There is no doubt in his mind that a lower limit for "substantially crystalline" should be adopted....

The Eastalco cases did not determine the exact percentage of crystallinity necessary for an article to meet the definition of "ceramic" and varying evidence has been submitted as to what is considered the proper percentage for an article to be "substantially crystalline." The Eastalco cases merely determined that the subject blocks, which were at the most 6% crystalline, were not "substantially crystalline" for tariff classification purposes.

The crystalline content of the graphite cathode blocks in this case is considerably different than the Eastalco blocks. Customs Laboratory Report 8-93-20950-001 dated September 2, 1993, examined the crystallinity of the subject graphite cathode blocks pursuant to the testing method established and agreed upon by the parties in Eastalco II. The analysis states that:

[T]his sample indicates that it is carbon (graphite) that is over 50% but less than 70% crystalline.

As the subject graphite cathode blocks are between 50% and 70% crystalline, they are not to be classified as the blocks were in the Eastalco cases. Based on the information before this office, we are of the opinion that the graphite cathode blocks are "substantially crystalline" and, therefore, meet the definition of a ceramic article and are classifiable within Chapter 69, HTSUS.

Furthermore, we are of the opinion that the graphite cathode blocks are classified under subheading 6902.90.10, HTSUS, as other refractory brick. The protestant states that like the blocks in the Eastalco cases, the graphite cathode blocks at issue have an initial electrical use. For a short period of time during the start-up phase of the cell, the graphite cathode blocks act as a cathode. After the start-up phase and after molten aluminum is added, a molten aluminum pad becomes the cathode. For the duration of the life of the furnace or cell, the graphite cathode blocks function primarily in their refractory capacity.

As found in the Eastalco cases, we believe that the graphite cathode blocks are not classifiable under subheading 8545.90.40, HTSUS, as other articles of graphite or other carbon, of a kind used for electrical purposes. The language "of a kind used for electrical purposes" indicates that heading 8545, HTSUS, is a use provision. Additional U.S. Rule of Interpretation 1(a), HTSUS, states that:

[A] tariff classification controlled by use (other than actual use) is to be determined in accordance with the use in the United States at, or immediately prior to, the date of importation, of goods of that class or kind to which the imported goods belong, and the controlling use is the principal use.

We note that the graphite cathode blocks have electrical properties. See, "DIRECT TESTIMONY of DR. VERNON BURDICK" (pgs. 10-11), and Aluminum, McGraw-Hill Encyclopedia of Science and Technology, Vol. 1, pgs. 418-419. However, we are of the opinion that the graphite cathode blocks are not principally used for electrical purposes. They are used for electrical purposes during the short start-up period of the furnace or cell. Thereafter and for the greater period of their useful life, they serve predominately as a refractory article. This conclusion is supported by the Court in Eastalco II which stated that the "...electrical properties, by themselves, did not make the refractory brick designation inappropriate." Therefore, as the graphite cathode blocks are not principally used for electrical purposes, they are not classified under subheading 8545.90.40, HTSUS.

HOLDING:

The graphite cathode blocks are classified under classified under subheading 6902.90.10, HTSUS, as other refractory bricks.

The protest should be GRANTED. In accordance with Section 3A(11)(b) of Customs Directive 099 3550-065, dated August 4, 1993, Subject: Revised Protest Directive, this decision should be mailed by your office to the protestant no later than 60 days from the date of this letter. Any reliquidation of the entry in accordance with the decision must be accomplished prior to mailing the decision. Sixty days from the date of the decision the Office of Regulations and Rulings will take steps to make the decision available to customs personnel via the Customs Rulings Module in ACS and the public via the Diskette Subscription Service, Freedom of Information Act and other public access channels.
