Commercial classification of thinners under sales tax law turned on predominant use, not isolated customer application.

Entry classification under the Bombay Sales Tax Act depended on the commercial meaning of "vehicles diluents and thinners" in Schedule C. Tol thinner and auto thinner, used for dissolving rubber in leather cloth manufacture rather than for reducing the viscosity of paints or lacquers, were not covered by that specific entry. The context of the composite expression, together with ejusdem generis and noscitur a sociis, required classification by general and predominant user. As the goods did not answer the specific description, they fell under the residuary entry in Schedule E.

Issues: Whether tol thinner and auto thinner were covered by entry 39(d) of Schedule C to the Bombay Sales Tax Act, 1959, or fell under the residuary entry 22 of Schedule E; and whether, if not covered by entry 39(d), they were taxable under the residuary entry with reference to the notification issued under section 41 of the Act.

Analysis: Entry 39(d) covered all kinds of vehicles diluents and thinners. The expression was read in context, and the word "vehicles" was understood as qualifying diluents and thinners in the setting of paint technology and allied materials. The goods were examined by their general and predominant user, not by a special or isolated customer use. On that basis, tol thinner and auto thinner, which were used for dissolving rubber in the manufacture of leather cloth and were not used for reducing the viscosity of paints or lacquers, did not answer the description of vehicles diluents and thinners. The interpretive aids of ejusdem generis and noscitur a sociis also supported this view.

Conclusion: Tol thinner and auto thinner did not fall under entry 39(d) of Schedule C and instead fell under entry 22 of Schedule E. The question was answered in the negative and in favour of the assessee.

Final Conclusion: The goods were held to be outside the specific tariff entry for vehicles diluents and thinners and to be assessable under the residuary schedule entry.

Ratio Decidendi: In a taxing entry, the meaning of a composite expression must be gathered from its context and predominant commercial use, and where the goods do not answer the specific description in the tariff entry, they fall to be classified under the residuary entry.
