Residuary classification applies to heat exchangers used as generator accessories, not as parts of generators.

Heat exchangers used to improve generator efficiency were held not to be parts of generators, because they served only as accessories and were used across multiple industries. The Tribunal ruled that the broad phrase "parts and accessories" in entry 41-D of the First Schedule to the Tamil Nadu General Sales Tax Act, 1959 could not be stretched to cover goods not specifically listed there. As heat exchangers were not otherwise enumerated in the Schedule, they fell within the residuary entry 81 as unenumerated goods and were taxable accordingly.

Issues: Whether heat exchangers were classifiable under entry 41-D of the First Schedule to the Tamil Nadu General Sales Tax Act, 1959 as parts and accessories of generators, or under entry 81 of the First Schedule as an unenumerated item.

Analysis: The Tribunal found that heat exchangers were used only as accessories to improve the efficiency of generators and were not themselves parts of generators. It also noted that heat exchangers were used across several industries and were not specifically mentioned anywhere in the First Schedule. The generic words "parts and accessories" in entry 41-D could not be extended to cover heat exchangers merely because they may also be used with generators. Since entry 81 applied to goods not specifically provided for elsewhere in the Schedule, the goods fell within that residuary entry.

Conclusion: Heat exchangers were not classifiable under entry 41-D and were rightly classifiable under entry 81 of the First Schedule to the Tamil Nadu General Sales Tax Act, 1959, taxable at 8 per cent. The revision was allowed in favour of the assessee.
