Tariff classification of woven polyester tapes turned on proven insulating character, not buyer's end use; classification under textile heading stood.

Woven polyester tapes manufactured from polyester filament yarn were held not to fall under the tariff heading for electrical insulators because the record did not show any proven insulating capacity or essential insulating character. The classification could not rest on the buyer's use of the goods for taping insulated coils or for mechanical protection during assembly, since end use alone is insufficient where the product does not itself answer the description of an insulator. The tapes were therefore classified under Chapter Heading 54.06, and the departmental appeal failed.

Issues: Whether woven polyester tapes were correctly classifiable as electrical insulators under Chapter Heading 85.46 of the Central Excise Tariff Act, 1985, or were classifiable under Chapter Heading 54.06.

Analysis: The product was manufactured as woven fabric/tape from polyester filament yarn and was used by the buyer for taping insulated coils and for mechanical protection during assembly. The material on record did not show that the goods possessed insulating capacity. The HSN Explanatory Notes to Heading 85.46 contemplate insulators used for fixing, supporting or guiding electric current conductors while electrically insulating them, and describe insulators as generally hard, non-porous articles with a functional insulating role. The authorities below found that the goods were only narrow polyester tapes without such insulating properties. The classification could not be based on end use alone, as the interpretative rules do not permit a product with multiple uses to be classified merely by one particular use.

Conclusion: The goods were not classifiable as electrical insulators under Heading 85.46 and were appropriately classifiable under Heading 54.06.

Final Conclusion: The departmental appeal failed and was dismissed, leaving the lower authorities' classification under Chapter 54.06 undisturbed.

Ratio Decidendi: For tariff classification, a product cannot be placed under the heading for electrical insulators unless its essential character and proven insulating function answer the description of that heading, and end use alone is insufficient where the goods do not possess insulating properties.
