Manufacturing machinery classification turns on functional role in production, not actual user-specific use, for oil engines.

Oil engines and their spare parts were classified under the manufacturing machinery entry in Schedule C because the controlling test was whether the goods were capable of being used in manufacture and played a necessary role in that process. Actual use by the particular assessee was not required where the machinery formed an essential and integral part of the plant and helped generate energy needed for production. The later amendment specifically including oil engines was treated as confirming the breadth of the entry. On that basis, the goods were held not to fall within the residuary entry in Schedule E, and the revenue's classification was rejected.

Issues: Whether oil engines and their spare parts, for the relevant periods, fell under entry 15 of Schedule C or entry 22 of Schedule E to the Bombay Sales Tax Act, 1959.

Analysis: Entry 15 was treated as a residuary entry for machinery, spare parts and accessories not otherwise specified. The controlling test was not whether the machinery was actually employed in the individual assessee's manufacturing process, but whether it was machinery capable of being used in the manufacture of goods and having a role in that process. Oil engines were found to be machinery which generated energy necessary for manufacture, and the earlier decision on humidifiers had already explained that machinery which plays some role in the process of manufacture and without which finished goods cannot be produced falls within the entry. The later legislative amendment, which specifically included oil engines, was also regarded as confirming the width of the entry.

Conclusion: Oil engines and their spare parts fell under entry 15 of Schedule C and not under the residuary entry 22 of Schedule E, and the answer was in favour of the assessee.

Final Conclusion: The taxable classification adopted by the revenue was rejected, and the goods were held to be covered by the manufacturing machinery entry under Schedule C.

Ratio Decidendi: For classification under the entry for machinery used in the manufacture of goods, actual user in the assessee's process is not required if the machinery is capable of and plays a necessary role in manufacture as an essential and integral part of the plant.
