Commercial identity governs sales tax classification; nylon fishnet twine was treated as a distinct multi-point commodity.

Fiscal classification under the Tamil Nadu General Sales Tax Act depends on the commercial identity of the goods in ordinary trade parlance, not their scientific composition. Nylon twine, including fishnet twine made by twisting yarn for a distinct and irreversible end-use, is commercially separate from nylon yarn or artificial silk yarn. The court distinguished authorities on cotton and woollen yarn, where twisting did not destroy the identity of yarn, and held that the specific entry for artificial silk yarn could not be extended by implication to nylon twine. The commodity was therefore treated as a multi-point item under section 3(1).

Issues: Whether nylon twine, including nylon fishnet twine and related forms described as knitting yarn, is classifiable under entry 18 of the First Schedule to the Tamil Nadu General Sales Tax Act, 1959 as artificial silk yarn, or is taxable as a multi-point item under section 3(1) of that Act.

Analysis: Classification under a sales tax entry must be determined by the popular or commercial meaning of the goods and not by their scientific or technical composition. Entry 18 covers artificial silk yarn, but nylon twine used for fishnets is commercially understood as a different commodity from nylon yarn. The material evidence showed that twine is manufactured by twisting yarn for a special end-use, namely fishnets and ropes, and that the process is irreversible. The Court distinguished cases involving cotton yarn and woollen yarn, where the identity of yarn was not lost by twisting or doubling, and preferred the line of authority treating nylon twine as a commercially separate product. It held that the entry could not be extended by implication to an item not specifically included by the legislature.

Conclusion: Nylon twine manufactured for fishnets does not fall within entry 18 of the First Schedule to the Tamil Nadu General Sales Tax Act, 1959 and is liable to be taxed as a multi-point item under section 3(1) of that Act.

Final Conclusion: The Revenue's classification was upheld, resulting in dismissal of the assessees' matters and allowance of the Revenue's revision petitions.

Ratio Decidendi: For fiscal classification, a commodity must be identified by its commercial identity in ordinary trade parlance; where processing creates a distinct and irreversible commercial product, it cannot be brought within a specific tariff entry meant for the original commodity.
