Automobile spare parts concession denied for speedometers, which were treated as accessories rather than essential vehicle components.

Under a sales tax concession notification for automobile tyres, batteries and automobile spare parts, a speedometer was treated as an accessory rather than a spare part. The governing test was whether the item formed an integral, essential and indispensable component of the vehicle and could be replaced as a spare; the Court said a vehicle can function without a speedometer, unlike tyres or batteries. Applying the ordinary commercial meaning of the term, the Court held that an article enhancing convenience and effectiveness does not become a spare part merely because it is used with the vehicle. The concessional rate therefore did not apply.

Issues: Whether speedometers sold for use in automobiles were covered by the expression "automobile spare parts" in Notification No. 86 of 1970 dated 18th March, 1970 so as to attract the reduced rate of sales tax at 13 per cent instead of 15 per cent.

Analysis: The reduced rate notification, issued under section 17 of the Tamil Nadu General Sales Tax Act, 1959, applied to automobile tyres, batteries and automobile spare parts. The decisive question was whether a speedometer was an essential and integral component of a vehicle or merely an article adding to convenience. The Court held that a vehicle can run without a speedometer, unlike tyres or batteries, and that the notification contemplated only a vital, indispensable part capable of being replaced by a spare. Applying the ordinary commercial meaning of "accessory" and the guidance of the cited authorities, the Court treated a speedometer as a fitting that enhances convenience and effectiveness, but not as a spare part of the vehicle.

Conclusion: Speedometers are accessories and not automobile spare parts within the notification; the sales turnover was rightly assessed at 15 per cent and not at 13 per cent.

Ratio Decidendi: For purposes of a concessional sales tax notification, only an integral, essential and indispensable component of the vehicle, capable of replacement by a spare, qualifies as an automobile spare part; an article that merely adds convenience is an accessory.
