Medical oxygen classified as a medicament where therapeutic purity and treatment use satisfied the statutory drug definition.

Medical oxygen with high purity and therapeutic use was treated as a medicament, because it was used in patient treatment to cure, alleviate, prevent disease, or restore health and the relevant tariff entries incorporated the statutory definition of "drug". Applying the accepted tests of medicinal content, curative function, and therapeutic use, it could not be classified merely as a general gas under the competing tariff entries. The penalty for belated payment was maintained as linked to delayed tax payment. The classification under the medicinal entries was therefore upheld for the relevant periods.

Issues: Whether medical oxygen is classifiable as a medicinal product under Entry 95 of Schedule-I Part-I for the year 1991-92 and Entry 20-A of Schedule-I Part-C for the years 1992-93 onwards, or as gas under Entry 106 of Schedule-I and Entry 25 of Schedule-I, and whether the penalty levied for belated payment could be interfered with.

Analysis: The classification turned on the nature and use of the product. The relevant tariff entries for the later period substantially incorporated the definition of drug from the Drugs and Cosmetics Act, 1940. Medical oxygen was found to have very high purity and to be used for treatment of patients in order to cure, alleviate, prevent disease, or restore health. Applying the accepted tests for a medicament, namely the medicinal content, curative function, and therapeutic use, the product satisfied the conditions of a medicinal item and could not be treated merely as a general gas. The penalty aspect was linked to delayed payment of tax and was maintained.

Conclusion: Medical oxygen was correctly classifiable under Entry 95 for 1991-92 and Entry 20-A for 1992-93 onwards, and not under the gas entries.

Final Conclusion: The revisions and writ petitions failed, and the classification in favour of the assessee was upheld.

Ratio Decidendi: A product that possesses therapeutic purity and is used for treatment, mitigation, prevention of disease, or restoration of health is classifiable as a medicament when the relevant tariff entry adopts the statutory definition of drug.
