Mutual exclusivity of manufacture and service tax bars levy on coal sizing treated as part of sale process

Sizing and crushing of coal on the assessee's own coal before title passed to buyers was treated as part of the sale/manufacturing process, not as production or processing of goods for or on behalf of a client under Business Auxiliary Service. The coal remained the assessee's property until delivery, the sizing charge formed part of the contracted sale price, and the activity was already subjected to central excise and VAT/CST, supporting the principle that manufacture and service tax are mutually exclusive levies. On those facts, sizing of coal was held not liable to service tax and the Revenue's demand failed.

Issues: Whether sizing/crushing of coal undertaken by the assessee for supply under the relevant contracts amounted to "production or processing of goods for or on behalf of the client" falling within Business Auxiliary Service and attracting service tax, or whether it formed part of manufacture and was therefore outside the service tax net.

Analysis: The coal remained the assessee's property until delivery under the contracts, and the sizing charges formed part of the contracted sale price. The activity was undertaken on the assessee's own coal before title passed to the buyers, so it was not carried out for and on behalf of a client. The process of sizing coal was also treated as incidental and ancillary to the completion of the manufactured product, and coal was regarded as excisable goods. The same activity had already been subjected to central excise duty on the assessable value and to VAT/CST on sale, which reinforced the position that the levy could not be shifted to service tax under a different taxing entry. In view of the principle of mutually exclusive levies, an activity treated as manufacture cannot simultaneously be taxed as a service.

Conclusion: Sizing of coal in the facts of the case was not liable to service tax under Business Auxiliary Service, and the Revenue's demand could not be sustained.
