Common parlance governs tariff classification; Rice Rubber Rolls fall under residual rubber articles and miss the exemption.

Rice Rubber Rolls are classified by their trade and common parlance identity, not by their cylindrical form: goods known in the market as Rice Rubber Rolls and used for shelling rice do not answer the description of tubes, pipes or hoses, so they fall under Heading 40.16 as other articles of vulcanised rubber. The exemption under Notification No. 197/67-C.E. is construed strictly and applies only to piping or tubing designed to be or converted into machine parts; because Rice Rubber Rolls are neither piping nor tubing nor so converted, the exemption does not apply. The classification and denial of exemption operate in Revenue's favour.

Issues: (i) Whether Rice Rubber Rolls are classifiable under Heading 40.09 as tubes, pipes and hoses of vulcanised rubber or under Heading 40.16 as other articles of vulcanised rubber. (ii) Whether Rice Rubber Rolls are entitled to exemption under Notification No. 197/67-C.E. dated 29-8-1967.

Issue (i): Whether Rice Rubber Rolls are classifiable under Heading 40.09 as tubes, pipes and hoses of vulcanised rubber or under Heading 40.16 as other articles of vulcanised rubber.

Analysis: The decisive test was the common parlance test, namely how the goods are known in the trade and understood by persons dealing with them. Rice Rubber Rolls were found to be marketed and known as Rice Rubber Rolls, used for shelling rice, and not as tubes, pipes or hoses. Their cylindrical shape was held insufficient to determine classification. The heading for tubes, pipes and hoses was treated as specific to articles answering that description, whereas the goods did not satisfy that description and fell within the residual but still specific chapter heading for other vulcanised rubber articles.

Conclusion: Rice Rubber Rolls are not classifiable under Heading 40.09 and are correctly classifiable under Heading 40.16 as other articles of vulcanised rubber, in favour of Revenue.

Issue (ii): Whether Rice Rubber Rolls are entitled to exemption under Notification No. 197/67-C.E. dated 29-8-1967.

Analysis: The exemption applied to piping and tubing designed to be or converted into component parts of machinery articles. Since Rice Rubber Rolls were held not to be piping or tubing and were not manufactured by conversion of piping or tubing into machine parts, the notification did not apply. The notification was construed strictly, and the claimed functional use as machine components was not enough to extend the exemption beyond its terms.

Conclusion: Rice Rubber Rolls are not entitled to exemption under Notification No. 197/67-C.E. dated 29-8-1967, in favour of Revenue.

Final Conclusion: The goods fall outside Heading 40.09, remain within Heading 40.16, and do not qualify for the claimed exemption, so the appellate relief granted below was reversed.

Ratio Decidendi: For tariff classification, the common parlance and trade understanding of the goods governs, and exemption notifications must be applied strictly according to their express terms.
