Common parlance and predominant use test applied to classify enamelled copper winding wire as spare parts under the concessional tax notification.

Enamelled copper winding wire was classified by applying its ordinary commercial identity, functional character and predominant use. The Court held that although the wire could transmit current, its accepted commercial role was to serve as an integral part in motors, armatures, chokes and similar electrical equipment, so it fell within the category of spare parts rather than ordinary electrical goods. The common parlance and predominant user tests were applied to bring the commodity within the concessional rate under the notification issued under section 17 of the M.P. Vanijyik Kar Adhiniyam, 1994. The commodity was therefore taxable at 4% under serial No. 10.

Issues: Whether enamelled copper winding wire was classifiable as an electrical good taxable at 10% or as spare parts of machinery and machines worked by electricity, diesel or petrol taxable at 4% under the relevant notification.

Analysis: The rate of tax had to be determined by the ordinary commercial understanding of the commodity and by its functional character and predominant use. Enamelled wire was used for winding in motors, armatures, chokes and similar electrical equipment, and its basic purpose was to serve as a part in machinery and machines rather than as an ordinary wire for transmission of current. The Court applied the common parlance and predominant user tests and held that an article capable of use as a part of machinery falls within the category of spare parts when that is its ordinary commercial identity and use. On that basis, the notification issued under section 17 of the M.P. Vanijyik Kar Adhiniyam, 1994 applied.

Conclusion: Enamelled wire was held to be spare parts covered by serial No. 10 of the notification and liable to tax at 4% only.

Final Conclusion: The tax classification made in the impugned order was set aside, and the commodity was brought within the concessional rate prescribed by the notification.

Ratio Decidendi: Classification of goods for sales tax purposes depends on their ordinary commercial identity and predominant functional use, and an article used as an integral part of machinery may be treated as spare parts where that is its accepted commercial character.
