Broad construction of registration certificate covers fire bricks as component parts for concessional tax treatment.

Fire bricks used in the smelter division were treated as covered by a registration certificate authorising purchase of air-cooling and heating equipment, accessories, components and spares for manufacture. On the Tribunal's factual finding that the bricks were heat-resistant materials lining the furnace and functioned as component parts of the plant and machinery, the expression in the certificate was construed broadly to include them. The concessional rate of tax was therefore available on the assessee's sales.

Issues: Whether fire bricks used in the smelter division of the purchasing dealer fell within the expression "air-cooling, heating equipments, accessories, components, spares, etc." in the registration certificate so as to justify concessional rate of tax on the assessee's sales.

Analysis: The purchasing dealer's certificate authorised purchase of air-cooling and heating equipments, accessories, components and spares for use in the manufacture of aluminium. The Tribunal recorded a factual finding that fire bricks were heat-resistant materials used for lining the furnace, which was part of the plant in the smelter division, and that they functioned as component parts of the manufacturing machinery. On that footing, the expression used in the certificate was construed broadly enough to cover the goods sold.

Conclusion: The fire bricks were covered by the registration certificate and the concessional rate of tax was rightly available to the assessee.

Ratio Decidendi: Where the registration certificate authorises purchase of equipments, components, accessories and spares for use in manufacture, a factually established item forming part of the plant or machinery and used in the manufacturing process may be treated as covered by that expression for concessional tax purposes.
