Commercial parlance test governs tax classification of mosquito repellent goods as insecticides, not unclassified items.

Mosquito mats, coils and refills were classified as insecticides under the relevant tax notifications because fiscal entries are construed in commercial parlance, not by scientific composition alone. The products contained allethrin, were marketed with insecticidal labelling, were covered by the Insecticides Act and Rules, and were treated in trade as insecticidal goods. The absence of a specific exclusion or separate entry for mosquito repellents during the relevant period meant they could not be taxed as unclassified goods, and the petitioners' challenge to the tax treatment succeeded.

Issues: Whether mosquito mats, coils and refills manufactured and sold as mosquito repellent goods were classifiable as "pesticides and insecticides" under the notifications issued under section 3-A of the U.P. Trade Tax Act, 1948, or were liable to be taxed as unclassified goods.

Analysis: The applicable notifications separately referred to "pesticides and insecticides" and did not contain any specific entry for mosquito repellent mats, coils or refills until the later notification expressly dealing with articles for destroying and repelling mosquitoes. The decisive question was the commercial identity of the goods in the relevant period. The Court applied the settled rule that fiscal entries must be construed in the sense in which the goods are understood in trade and by consumers, not by their scientific composition alone. On the evidence, the products contained allethrin, were marketed with insecticidal labelling, were covered by the Insecticides Act, 1968 and the Insecticides Rules, 1971, and were treated in the trade and by prior judicial decisions as insecticidal products. The mere description of the goods as mosquito repellents in registration documents and returns did not alter their essential character in the absence of a specific exclusion or separate entry.

Conclusion: The goods were held to fall within the expression "insecticides" in the relevant notifications and not within the residuary unclassified category; the challenge to the tax treatment succeeded in favour of the petitioners.

Ratio Decidendi: For classification under a taxing notification, the determinative test is the common or commercial parlance understanding of the goods, and where no specific entry excludes the goods, products commercially and functionally understood as insecticidal may be classified as insecticides notwithstanding their scientific composition or their description as mosquito repellents.
