This appeal is from the judgment of the United States Customs ’Court, 76 Cust. Ct. 1, C.D. 4626, 408 F. Supp. 1377, sustaining ap-pellee’s claim that its imported merchandise is entitled to classification under item 771.40, Tariff Schedules of the United States (TSUS), •instead of under item 355.82, TSUS, as classified. Appellee alternatively claimed classification under items 771.42, 774.60 and 355.85. We affirm.
The pertinent statutory provisions involved in this appeal, with ¡rates of duty in effect at time of importation, are as follows:

The legislation under which this interrelated maze of provisions was devised was known, somewhat ironically, as the Customs Simplification Act of 1954, 68 Stat. 1136, Pub. L. 768, 83rd Cong. 2d Sess. [Emphasis supplied.]
The merchandise, invoiced as “Polyurethane 305,” consists of flexible sheets of a laminated material imported in rolls. The material has a glossy polyurethane “skin” on one side and a nylon fabric on the reverse side. The evidence of record (four exhibits and the testimony of three witnesses) unequivocally establishes that the principal and only use of the merchandise is as a substitute for patent leather in the construction of footwear, the polyurethane skin being always outside. Similar material is sometimes used in ladies handbags.
The Customs Court read General Headnote 9 (f) (i) in conjunction with the language “of textile materials” in the superior heading to item 355.82 to require that the merchandise be wholly or in chief value of the nylon fabric as a prerequisite for proper classification *102under item 355.82. General Headnote 10 of the TSUS defines chief value as follows:
(f) an article is in chief value of a material if such material exceeds in value each other single component material of the article.
Since the testimony established the costs of the components of the nylon fabric and polyurethane coating as 51 cents and $1.13, respectively, the court held that the merchandise did not meet the chief value test and was, therefore, improperly classified. The court then turned to appellee’s proposed classification of the merchandise under item 771.40. It held that the merchandise was “almost wholly of” plastics, as the quoted term is defined in General Headnote 9 (f) (iii), because the essential character thereof was imparted by the polyurethane “skin.” The court also noted the unrebutted testimony of record which established that the merchandise was made in imitation of selected varieties of patent leather in holding that classification under item 771.40 was proper.
Appellant contends that the court erred in applying the chief value test of General Headnote 9 (f) (i) to the whole (as opposed to the nylon portion) of the merchandise. It argues that the language of the superior heading to items 355.65-.85, headnotes 2(a)(iv) and 4(b) to schedule 3, headnote 2(c) to part 40 of schedule 3, and amendments to schedules 3 and 7 of the TSUS by the Tariff Schedules Technical Amendments Act of 1965 (TSTAA) 2 and related legislative history,, all specifically provide for the classification of the merchandise under item 355.82.
Appellant also contends that classification under item 771.40 is improper because the polyurethane “skin” does not impart the essential character to the merchandise. Thus, it is not “almost wholly of” plastics within the meaning of General Headnote 9(f)(iii). Alternatively, appellant contends that if the merchandise is described under both items 355.82 and 771.40, then the rule of relative specificity requires classification under item 355.82. Finally, appellant argues that if this court finds both provisions equally applicable, even under the rule of relative specificity, item 355.82 must prevail by virtue of General Interpretative Rule 10(d), which provides:
(d) if two or more tariff descriptions are equally applicable to-an article, such article shall be subject to duty under the description for which the original statutory rate is highest * * *
Appellee contends that the Customs Court properly applied a chief value test in holding the merchandise improperly classified under *103item 355.82. It also contends that the evidence of record supports the court’s finding that the merchandise is “almost wholly of” plastics and made in imitation of patent leather. Thus, it argues that classification under item 771.40 was proper. It also contends that if classification under item 771.40 is proper, then headnote 1 (vii) to part 40 of schedule 3 excludes classification of the merchandise in part 40.
Headnote l(vii) to part 4C of schedule 3 provides the proper starting point for analyzing the present controversy. That headnote excludes from classification in part 40 “other articles specially provided for in schedule 7 or elsewhere.” A proper inquiry is whether the Customs Court correctly held that the merchandise is properly classified under item 771.40. If it did, then perforce the merchandise cannot be properly classified under item 355.82.
The evidence and admissions of record unquestionably establish that the imported merchandise is a film or sheet of laminated material in rectangular pieces over 15 inches in width and over 18 inches in length, as prescribed in the superior heading to item 771.40. The polyurethane component is not of cellulosic plastics material as also therein prescribed, and, as noted, the merchandise was made in imitation of patent leather. A crucial question is whether the merchandise is “almost wholly of” polyurethane. [1] Headnote 9 (f) (iii) requires that to be “almost wholly of” polyurethane the merchandise must have its essential character imparted by the polyurethane, notwithstanding the fact that a nylon backing is also present. The record amply supports the Customs Court in holding that the polyurethane supplies this essential character. It is the distinctive visual and tactile quality of polyurethane which gives the merchandise its ability to be used as an imitation patent leather. It is in fact indispensible. In this regard the polyurethane in this case is like the glass water ball in United China & Glass Co. v. United States, 61 Cust. Ct. 386, C.D. 3637, 293 F. Supp. 734 (1968). The nylon fabric backing, although imparting several desirable properties to the merchandise, is not indispensible. When footwear is constructed, only the polyurethane is visible. The various flexing and cracking tests which were performed on the merchandise to determine its suitability as an imitation patent leather all related to the durability of the glossy surface. There is no evidence of record showing a like concern over the durability of the fabric backing. In fact, although some form of backing is usually applied to the polyurethane, the fabric backing need not be of nylon; other material can be and is used and sometimes the polyurethane is sold unbacked.
We have reviewed Marshall Co. v. United States, 67 Cust. Ct. 316, C.D. 4291, 334 F. Supp. 643 (1971), cited by appellant. See also A. N. Deringer, Inc. v. United States, 66 Cust. Ct. 378, C.D. 4218 (1971), and Larry B. Watson Co. v. United States, 64 Cust. Ct. 343, *104C.D. 4001 (1970). Our first observation is tbat these prior cases are of little help in determining that which supplies the essential character to imported merchandise. These determinations are essentially factual and vary from case to case. Moreover, Marshall is inapposite to the present controversy. In Marshall a rayon fabric coated on both sides with rubber was held not to be almost wholly of rubber because the rubber did not impart the essential character to the imported merchandise. The involved merchandise was used in the manufacture of packing materials such as gaskets, washers, and packing heads, and diaphragm material. The court noted that the fabric portion gave burst strength and dimensional stability to the merchandise, preventing the stretching or tearing of the rubber compounds, finding these qualities to be equally essential to those imparted by the rubber in view of the ultimate use of the products. Here, as noted, there is no evidence that the polyurethane and the nylon fabric are equally essential and all the evidence is contrary. In our view it is the polyurethane alone which makes the imported merchandise an imitation of patent leather.
Appellant argues that classifying a “supported” plastic under item 771.40 runs counter to the legislative history3 relating to an amendment of that provision. Prior to the enactment of the TSTAA the superior heading to item 771.40 read as follows:
Film, strips, and sheets, all the foregoing which are flexible and unsupported:
The TSTAA amended this superior heading to delete the words “and unsupported.” On its face, the amendment was of a broadening nature and caused the amended superior heading to encompass both supported and unsupported rubber or plastics. Generally, a change in the language of a statute indicates an intent to change its meaning. United States v. American Brown Boveri Electric Corp., 17 CCPA 329, T.D. 43776 (1929). However, the legislative history surrounding this amendment states:
Subsection (c) would amend the article description for items 771.40-771.42 which cover rubber and non-cellulosic plastics in the form of film, strips, and sheets “which are flexible and unsupported.” It is proposed to strike out the words “and unsupported.” These words are surplusage. Where such film, strips, and sheets are supported, textile fabrics are the usual supporting media and such products are provided for in items 355.65-355.85
Despite lending apparent support for appellant’s position, we are not prepared to give this report overriding significance. We do not nor*105mally use an indication of Congressional intent alone to overcome the clear meaning of the words of a statute. American Customs Brokg. Co. v. United States, 58 CCPA 45, C.A.D. 1002, 433 F. 2d 1340 (1970); C. J. Tower & Sons v. United States, 41 CCPA 195, C.A.D. 550 (1954); Yardley & Co. v. United States, 41 CCPA 85, C.A.D. 533 (1953). Particularly where, as here, the legislative history itself is not entirely free of ambiguity. Although Congress seemingly thought that all textile fabric supported films, sheets, etc. cf rubber or ncn-cellulosic plastics were provided for under item 355.65-.85, the TSUS, particularly headnote 2(c) to part 4C of schedule 3, clearly provides otherwise. “In resolving ambiguity we must allow ourselves some recognition of the existence of sheer inadvertence in the legislative process.” Cass v. United States, 417 U.S. 72, 83 (1974) We are not prepared to alter the clear meaning of the statute because of an ambiguous legislative history.
Appellant also contends that the imported merchandise is not an “article” which is embraced by part 12 of schedule 7, noting that headnote 2(a)(vi) of schedule 3 and headnote 5 of schedule 3 combine to exclude only certain articles made from the fabrics provided for in part 4C of schedule 3 from the textile provisions of schedule 3. As previously noted, headnote l(vii), which specifically covers part 4C of schedule 3, also excludes from that part “articles specially provided for in schedule 7 or elsewhere.” The articles which are excluded from schedule 3 by virtue of the headnotes, says appellant, are finished products such as suitcases, gloves, etc., as discussed in the legislative history cited above concerning the TSTAA which added headnotes 2(a) (vii) and 5 to schedule 3:
Subsection (a) would amend the definition of “textile materials” in headnote 2(a) of schedule 3. Under subparagraph (iv) of headnote 2(a) the fabrics in question are specifically identified as “textile materials”. The proposed amendment takes into account the consideration mentioned above that the textile characteristics of these fabrics may be completely lost in the final product. For example, simulated leather suitcases and gloves made of a “supported” vinyl bear no outward resemblance to a textile prod-duct. Thus, the proposed amendment of headnote 2(a) would exclude such fabrics from the defined concept of “textile materials” and provide for their being regarded as wholly of rubber or plastics to the extent that, as used in the luggage, gloves, or other article made therefrom, nontransparent rubber or plastics form either the outer surface of the article or the only exposed surface of the fabric.
However, we find no basis in the statute or even in the cited legislative history to read the word “article” in such restrictive manner. Although finished products such as gloves and luggage are dis*106cussed in the legislative history as examples of "articles,” there is no narrowing definition given therein for the term. In our view the films, strips, sheets, etc. enumerated in the superior heading to item 771.40 are all articles which aie excludable from schedule 3 by virtue of headnote l(vii) to part 4C of schedule 3, provided they meet the other classification requirements in issue. This view, which is contrary to that expressed by the court in Marshall, supra, is reinforced by the Tariff Classification Study, Submitting Report (1960) (TCS), Schedule 7, p. 440, which states:
[T[he proposed provisions of part 12 [of schedule 7] do not distinguish between products on the basis of whether they are or are not made into finished or partly finished articles. Objective distinctions based on specified dimensions have been substituted.
When specifically discussing part 12B of schedule 7 and its related headnotes, the above TCS at 450 states:
The provisions of headnotes 1 and 2 of this subpart treat objectively with the existing problem of differentiating between plastic products which have and have not “been made into finished or partly finished articles.” The proposed distinctions are based on dimensions and the type of processing involved.
In view of the above, we hold that the imported merchandise was properly classified under item 771.40 by the Customs Court. As a result, the imported merchandise is properly excluded from part 4C of schedule 3 by virtue of headnote l(vii) thereto. Our conclusion does not require support of the chief value test which was applied by the Customs Court in holding that classification of the imported merchandise under item 355.82 was improper. Assuming appellant is right that Congress did not mean the chief value test to govern the classification of laminated fabrics of textile and plastic, we think it clearly did mean the "almost wholly” test to govern here, and the contrary conclusion would be anomalous and a trap for unwary importers.
The judgment of the Customs Court is affirmed.
