Processed textile goods lose exemption when manufacture creates a distinct commercial commodity; turnover computation errors still warranted remand.

Waterproof cotton canvas cloth, after treatment with wax, resin and colour, was treated as a distinct commercial commodity and not as "all varieties of textile fabrics" under rule 3(28)(a) of the Bengal Sales Tax Rules, 1941; the exemption therefore did not apply and tax on its sale was upheld. The material also showed possible mistakes in measurement, the rupee notation before figures, and the stock-sales basis used in computing turnover, so the assessment was remanded for limited reconsideration of those computational issues by the competent appellate authority.

Issues: (i) Whether waterproof cotton canvas cloth fell within the expression "all varieties of textile fabrics" under rule 3(28)(a) of the Bengal Sales Tax Rules, 1941 and was exempt from tax. (ii) Whether the assessment required interference on account of alleged errors in measurement and computation of sale turnover.

Issue (i): Whether waterproof cotton canvas cloth fell within the expression "all varieties of textile fabrics" under rule 3(28)(a) of the Bengal Sales Tax Rules, 1941 and was exempt from tax.

Analysis: Rule 3(28)(a), as applicable during the relevant period, gave a restricted meaning to "textile fabrics" and expressly excluded certain processed articles. The later omission of "waterproof cloth" from the explanation did not by itself bring waterproof canvas cloth within the exemption. The process of applying wax, resin and colour transformed the base canvas into a commodity with a distinct identity, use and market understanding. On the common parlance and user tests, the processed article was not merely canvas cloth simpliciter, but a different commercial commodity.

Conclusion: Waterproof cotton canvas cloth was not covered by rule 3(28)(a) and the levy of tax on its sale was upheld.

Issue (ii): Whether the assessment required interference on account of alleged errors in measurement and computation of sale turnover.

Analysis: The assessment record disclosed mistakes in the use of the abbreviation for rupees before measurement figures and a possible error regarding the basis of stock and sales correlation. The question of the proper unit of measurement also remained unresolved on the material before the Court. These matters affected the correctness of the turnover computation and required reconsideration by the competent appellate authority.

Conclusion: The assessment required remand for reconsideration of the computational and measurement issues.

Final Conclusion: The taxability of waterproof cotton canvas cloth was affirmed, but the assessment was set aside for limited reconsideration of the measurement and turnover computation issues by the appellate authority.

Ratio Decidendi: A processed article which acquires a distinct identity, use and commercial recognition after manufacture is not to be treated as the original textile fabric merely because the base material remains traceable underneath.
