Motor vehicle component classification: valves used in truck diesel engines were treated as parts of motor vehicles under sales tax law.

In sales tax classification, inlet and exhaust valves used in diesel engines fitted in trucks were treated as components of motor vehicles under entry 58(2) of Schedule C to the Bombay Sales Tax Act, 1959. The court applied the ordinary use test and held that a component of a component does not lose its character as a component of the motor vehicle where the intermediate part is ordinarily used in the vehicle without adaptation. Possible alternative uses in tractors, launches, or earth-moving machinery did not displace that classification on the facts proved, and the departmental classification was upheld.

Issues: Whether inlet and exhaust valves used in diesel engines fitted in trucks were covered by entry 58(2) of Schedule C to the Bombay Sales Tax Act, 1959 as components or spare parts of motor vehicles.

Analysis: Components are constituent parts used in the manufacture of the finished product, while spare parts are those kept ready to replace worn-out component parts. Applying the ordinary use test, diesel engines fitted in trucks were held to be components of motor vehicles. The qualifying words in entry 58(2) governing articles ordinarily used otherwise than as parts and accessories were held not to exclude diesel engines fitted in trucks without adaptation. It was further held that a component of a component of a motor vehicle does not cease to be a component of the motor vehicle, and the alleged alternative use of the engines in tractors, launches, or earth-moving machinery did not dislodge their character in the facts proved.

Conclusion: The valves were covered by entry 58(2) as components of motor vehicles through their use in diesel engines fitted in trucks, and the reference was answered against the assessee and in favour of the department.

Final Conclusion: The tax classification adopted by the department was upheld, and the assessee did not succeed in challenging the applicability of the relevant sales tax entry.

Ratio Decidendi: A component of a component of a motor vehicle is itself a component of the motor vehicle where the intermediate component is ordinarily used as such in the vehicle and does not require adaptation for that use.
