Exemption for rubber machinery components cut from tubing applies where the goods do not convey air, gas, or liquid.

Rubber aprons and cots cut within the factory from unhardened vulcanised rubber piping and tubing were treated as component parts of textile machinery, not mere accessories. The court held that Notification No. 197/67 applied because the goods were designed to be converted into machinery components and did not function as conveyors of air, gas, or liquid. On that footing, they were not liable to excise duty under the residuary tariff item, and the demand, penalty, revisional order, and appellate order based on that classification were unsustainable and set aside.

Issues: (i) Whether rubber aprons and cots manufactured from piping and tubing of unhardened vulcanised rubber fell within Notification No. 197/67 and were exempt from excise duty; (ii) whether the demand of duty, penalty, and revisional and appellate orders based on classification under the residuary tariff item could stand.

Issue (i): Whether rubber aprons and cots manufactured from piping and tubing of unhardened vulcanised rubber fell within Notification No. 197/67 and were exempt from excise duty.

Analysis: The articles were found to be cut from piping and tubing within the factory, retaining their character as piping/tubing converted into smaller units. The notification exempted piping and tubing of unhardened vulcanised rubber designed to be or converted into component parts of machinery, provided they did not function as conveyors of air, gas, or liquid. The Court accepted that aprons and cots were component parts of textile machinery, not mere accessories, and that they did not perform any conveying function. The reasoning rejected the Collector's reliance on nomenclature in technical standards as determinative of their legal character.

Conclusion: Yes. The aprons and cots were exempt under the notification and were not excisable.

Issue (ii): Whether the demand of duty, penalty, and revisional and appellate orders based on classification under the residuary tariff item could stand.

Analysis: Once the goods were held not excisable and covered by the exemption, the foundation for the demand under the residuary tariff item disappeared. The revisional order, the adjudication confirming duty and penalty, and the appellate tribunal's order all rested on the erroneous premise that the goods were liable to duty.

Conclusion: No. The demand, penalty, revisional order, and tribunal order were unsustainable and were set aside.

Final Conclusion: The petition succeeded, the exemption was upheld, and the excise demand and penalty were quashed.

Ratio Decidendi: Where rubber tubing is converted within the factory into component parts of machinery and the resulting goods do not convey air, gas, or liquid, they fall within the exemption notification and cannot be assessed to excise duty under the residuary entry.
