Classification under sales tax law turns on specific entries first; nitrous oxide was remitted, while industrial gas classification was upheld.

Nitrous oxide used as an anaesthetic in hospitals and nursing homes required reconsideration for classification under the Kerala General Sales Tax Act because a residuary or general entry could not be applied without first testing whether it fell within a specific entry, including the medicine entry. The finding that it was unclassified was set aside and the matter remitted for fresh consideration. Hydrogen, argon and argon nitrogen mixture were treated as gases supplied for industrial use, and that commercial and functional character supported classification as industrial gases under the relevant entry. The industrial gas classification was upheld, leaving the revisions successful only in part.

Issues: (i) Whether nitrous oxide was classifiable under entry 71 of the First Schedule to the Kerala General Sales Tax Act or had to be reconsidered with reference to other specific entries, including entry 74 for medicine. (ii) Whether hydrogen, argon and argon nitrogen mixture were industrial gases falling under entry 59 of the First Schedule to the Kerala General Sales Tax Act.

Issue (i): Whether nitrous oxide was classifiable under entry 71 of the First Schedule to the Kerala General Sales Tax Act or had to be reconsidered with reference to other specific entries, including entry 74 for medicine.

Analysis: Nitrous oxide was found to be a gaseous substance supplied to hospitals and nursing homes for use as an anaesthetic agent. The residuary entry for chemicals could apply only if the goods did not fall under any other specific entry in the First Schedule. The existence of a specific entry for medicine required examination of whether the product answered that description before treating it as an unclassified item.

Conclusion: The finding that nitrous oxide was an unclassified item was set aside and the question was remitted for fresh consideration of its proper entry in the First Schedule, including entry 74.

Issue (ii): Whether hydrogen, argon and argon nitrogen mixture were industrial gases falling under entry 59 of the First Schedule to the Kerala General Sales Tax Act.

Analysis: These commodities were treated as gases supplied for industrial use, and that factual and commercial character supported classification under the entry for industrial gases.

Conclusion: The classification under entry 59 was upheld in favour of the assessee.

Final Conclusion: The revisions succeeded only in part. The classification of nitrous oxide was reopened for reconsideration, while the classification of hydrogen, argon and argon nitrogen mixture under the industrial gas entry was sustained.

Ratio Decidendi: A residuary or general classification cannot be applied without first considering whether the goods fall under any specific entry, and classification must be determined by the goods' commercial and functional character.
