The steel plates and M.S. Channels, used in the fabrication of chimney would fall within the ambit of "capital goods" as contemplated in Rule 57Q. It is not the case of the Revenue that both these items are not required to be used in the fabrication of chimney, which is an integral part of the diesel generating set, particularly when the Pollution Control laws make it mandatory that all plants which emit effluents should be so equipped with apparatus which can reduce or get rid of the effluent gases. Therefore, any equipment used for the said purpose has to be treated as an accessory in terms of serial No.5 of the goods described in column (2) of the Table below Rule 57Q. The Tribunal was correct in law in holding that the assessee was entitled to avail of MODVAT credit in respect of the subject items viz. steel plates and M.S. channels used in the fabrication of chimney for the diesel generating set, by treating these items as capital goods in terms of Rule 57Q of the Rules. Appeal preferred by the Revenue dismissed accordingly.
