Accessory vs part distinction: plough lamp for a tractor was held non-essential, so tractor part exemption was unavailable.

A plough lamp fitted to a tractor was treated as an accessory rather than a part because the tractor remained complete and functional without it, and the lamp only improved convenience for night ploughing. Chapter Note 2 of Chapter 87 supported the distinction between tractors and interchangeable equipment, and the lamp was separately classifiable under Heading 85.12. Classification could not be altered by valuation practice, and the trade notice relied on also treated plough lamps as accessories. On that basis, the exemption limited to parts of a tractor under Notification No. 239/86-C.E. was not available.

Issues: Whether a plough lamp fitted to a tractor is a part of the tractor or merely an accessory, and whether it is eligible for exemption under Notification No. 239/86-C.E. dated 03.04.1986.

Analysis: Chapter Note 2 of Chapter 87 of the Central Excise Tariff Act, 1985 treats tractors as vehicles constructed for hauling or pushing, and machines or working tools designed as interchangeable equipment retain their own classification. The plough lamp was separately classifiable under Heading 85.12, and its use was only to facilitate night ploughing. The tractor remained complete and functional without it. On the settled distinction between a part and an accessory, an article is a part only if the principal item is incomplete without it, whereas an accessory merely adds to convenience or effectiveness. The record also showed that classification cannot be controlled by valuation practice, and the trade notice relied upon by the assessee treated plough lamps as accessories for assessable value purposes.

Conclusion: The plough lamp is an accessory and not a part of the tractor, so the exemption under Notification No. 239/86-C.E. dated 03.04.1986 is not available.

Ratio Decidendi: For exemption limited to parts of a tractor, an item that is not essential to the tractor's completeness and only improves convenience or effectiveness is an accessory and not a part.
