Case Note & Summary
The case involved appeals by assessees challenging the classification of ultramarine blue for sales tax purposes under the Tamil Nadu General Sales Tax Act, 1959. The primary dispute was whether ultramarine blue should be classified as a pigment under Item 110 or as a chemical under Item 138. The High Court had concluded that ultramarine blue was a pigment, a decision the Supreme Court upheld. The court examined various judgments from other High Courts, including Madhya Pradesh, Rajasthan, and Gujarat, which had previously addressed the classification of ultramarine blue. The court noted that ultramarine blue is commonly understood as a pigment used for whitening clothes and is recognized in dictionaries as such. The court emphasized that the product's classification should be based on its common understanding and usage in the market. The Supreme Court dismissed the appeals, affirming that ultramarine blue is a pigment and thus subject to sales tax under Item 110, with no order as to costs.
