Custom-made power tiller shafts classified as parts of power tillers, not transmission shafts, on expert technical evidence.

Custom-made shafts for power tillers were held not classifiable as transmission shafts under Heading 84.83 because technical inspection showed that most of the shafts were stationary machine elements and did not transmit power, even though they were used in the transmission gear box. The side clutch shaft was identified as the only component that actually transmitted power. On that evidence, the goods could not be classified as transmission shafts merely by association with a gearbox assembly, and Heading 84.83 was found unsustainable. The appropriate classification was Heading 84.32 as parts of power tillers.

Issues: Whether the impugned shafts were correctly classifiable as transmission shafts under Heading 84.83 of the First Schedule to the Central Excise Tariff Act, 1985, or as parts of power tillers under Heading 84.32.

Analysis: The technical report from engineering experts, prepared after inspection of the factory and the goods, stated that most of the shafts were stationary machine elements that did not transmit power, even though they formed part of the transmission gear box. It also distinguished the side clutch shaft as the only component that transmitted power. On that basis, the goods could not be treated as transmission shafts merely because they were used in a gear box assembly. Since the goods were custom-made for V.S.T. power tillers and did not perform power transmission in the manner required by Heading 84.83, the classification adopted in the impugned orders was found unsustainable. The appropriate classification was held to be Heading 84.32.

Conclusion: The goods were not classifiable under Heading 84.83 as transmission shafts and were correctly classifiable under Heading 84.32 as parts of power tillers; the appeals were allowed in favour of the assessee.

Ratio Decidendi: Where the evidence shows that the goods do not transmit power, their classification cannot be sustained as transmission shafts, and expert technical opinion deserves due weight unless displaced by contrary evidence.
