Tariff classification of glass fibre insulators upheld under the specific mineral fibres entry, excluding the residuary item.

The Tribunal could examine the post-1-3-1979 classification issue even though the lower appellate authority had not dealt with it, because omission by the appellate authority could not curtail appellate scrutiny of the correct tariff classification. Electrical insulators made of glass fibre reinforced plastics were held classifiable under Item 22F, as amended, because the entry expressly included glass fibre by deeming provision and covered manufactures in which mineral fibres or yarn predominated in weight; the goods were predominantly composed of glass fibre and yarn, with resin and chemicals only subsidiary. Item 68, being residuary, could not apply once the specific entry governed the goods. The departmental classification was therefore sustained.

Issues: (i) whether the Tribunal could examine the classification of the goods for the post-1-3-1979 period though the Collector (Appeals) had not dealt with it; and (ii) whether electrical insulators made of glass fibre reinforced plastics were classifiable under Item 22F of the Central Excises and Salt Tariff or under Item 68.

Issue (i): whether the Tribunal could examine the classification of the goods for the post-1-3-1979 period though the Collector (Appeals) had not dealt with it.

Analysis: The objection was overruled because the appellate authority was bound to decide the issue and its omission could not deprive the Tribunal of power to examine the matter in appeal. The failure of the lower appellate order to address the post-1-3-1979 period did not prevent determination of the correct classification.

Conclusion: The Tribunal could go into the post-1-3-1979 classification issue.

Issue (ii): whether electrical insulators made of glass fibre reinforced plastics were classifiable under Item 22F of the Central Excises and Salt Tariff or under Item 68.

Analysis: Item 22F, as amended, expressly included glass fibre and yarn within the expression "mineral fibres and yarn and manufactures therefrom" by a deeming provision, and also covered manufactures in which mineral fibres or yarn predominated in weight. The goods were composed predominantly of glass fibre and yarn, with resin and chemicals being subsidiary constituents. Item 15A(2) was excluded by its amendment, while Item 68 was only residuary and could be used only after the specific entries were ruled out. On that construction, the goods fell within the more specific tariff entry.

Conclusion: The goods were correctly classifiable under Item 22F and not under Item 68.

Final Conclusion: The tariff entry covering mineral fibres and their manufactures governed the goods, so the departmental classification was sustained and the appeal failed.

Ratio Decidendi: Where a tariff entry expressly includes a material by deeming provision and applies a predominance test, goods predominantly composed of that material fall under the specific entry and not the residuary entry.
