Compressed air production from atmospheric air constitutes manufacture of excisable goods under Section 65(105)(zzzy), not mining services.

CESTAT Kolkata held that appellant's operation of HPMACs to produce compressed air for ONGC constituted manufacture of excisable goods under Tariff Heading 28530030, not mining services. The tribunal ruled that compressed air production from atmospheric air creates a new identifiable commodity chargeable to nil duty rate. Since appellant was responsible only for compressed air production and not oil exploration, and payment was not based on oil quantum explored, the activity could not be categorized as mining service under Section 65(105)(zzzy) of Finance Act, 1994. Service tax demand and penalties were set aside; appeal allowed.

1. ISSUES PRESENTED AND CONSIDERED

1. Whether the activity of operating High Pressure Mobile Air Compressors (HPMACs) to produce and supply compressed air at oilfield sites constitutes "manufacture" of excisable goods within the meaning of Section 2(f) of the Central Excise Act.

2. Whether the ownership of the plant and machinery (HPMACs) by the contractee (ONGC) rather than the contractor precludes classification of the activity as manufacture and, therefore, permits imposition of Service Tax as a "mining service" under Section 65(105)(zzzy) of the Finance Act.

3. Whether the services rendered, measured and remunerated on the basis of supply/operation of compressed air (as opposed to exploration output), fall within the definition of "mining service" so as to attract Service Tax, and whether any penalty/interest consequent on such demand is sustainable.

2. ISSUE-WISE DETAILED ANALYSIS

Issue 1 - Manufacture of compressed air: legal framework

Legal framework: "Manufacture" is defined in Section 2(f) of the Central Excise Act to include processes incidental or ancillary to completion of the manufactured product; "excisable goods" are goods specified in the Tariff Schedule. Compressed air (compressed gas) is specified under the Tariff Heading corresponding to compressed gases.

Precedent treatment: Authorities have recognized compression of atmospheric air into compressed gas as manufacture of excisable goods where a new identifiable commodity emerges from raw material (atmospheric air).

Interpretation and reasoning: The Tribunal examined the contractual scope (operation and maintenance of compressors; supply of compressed air) and found the end result to be production of a new identifiable commodity-compressed air-distinct from raw atmospheric air. The fact that compressed air is identified in the Tariff and that the process resulted in a new product supports classification as manufacture.

Ratio vs. Obiter: Ratio - where processes result in a new identifiable commodity specified in the Tariff, they amount to "manufacture" within Section 2(f). Obiter - none material regarding ancillary factual distinctions beyond the contracts at hand.

Conclusion: The activity of operating HPMACs to produce and supply compressed air constitutes "manufacture" of excisable goods chargeable under the Tariff (nil rate in the facts), and therefore prima facie falls within the Central Excise domain rather than service taxation.

Issue 2 - Effect of ownership of plant and machinery on classification

Legal framework: Central excise liability is founded on production/manufacture of excisable goods; statutory definition of "manufacturer" and principles recognize that ownership of plant/machinery is not determinative of excise liability where production occurs under the contractor's operation.

Precedent treatment: Authorities have held that the person in whose hands excisable goods are produced is liable for excise; ownership of machinery is not a criterion to convert a manufacturing activity into a service. Prior decisions that considered manufacture even where plant was not owned by the producer support this stance.

Interpretation and reasoning: The Tribunal compared two sets of contracts identical in operative terms except for ownership of the HPMACs. In both, the contractor operated and maintained compressors and supplied compressed air. Since the operative functions and end product were identical, ownership alone was held insufficient to recharacterize the activity as a service subject to Service Tax. The Tribunal emphasized that the end result and the nature of the process control the classification.

Ratio vs. Obiter: Ratio - ownership of plant/machinery does not negate manufacture where the contractor operates plant to produce an excisable product; classification depends on nature of activity and end product, not mere ownership.

Conclusion: Ownership of HPMACs by the contractee (ONGC) does not preclude treatment of the activity as manufacture; thus ownership cannot convert a manufacturing activity into a taxable "mining service."

Issue 3 - Whether activities amounted to "mining service" and sustainment of Service Tax/penalty

Legal framework: "Mining service" under Section 65(105)(zzzy) of the Finance Act covers services in relation to mining/exploration activities as defined in that provision; Service Tax applies where the activity falls within statutory service definitions and is not excluded by excise characterization.

Precedent treatment: Courts have analyzed scope of services rendered for oilfield operations to determine whether they constitute services in relation to mining/exploration; prior decisions have found specific vessel and related services to be "mining service" depending on contractual obligations and the nature of work.

Interpretation and reasoning: The Tribunal reviewed the contractual scope and operational details and found the contractor's obligation limited to operation, maintenance, mobilization and supply of compressed air; oil exploration itself was not entrusted to the contractor, nor was remuneration tied to exploration output. The supply of compressed air was the measurable deliverable. Thus, the activity did not constitute a service in relation to mining/exploration under the statutory definition, and the imposition of Service Tax as "mining service" on the two contracts (where compressors were ONGC-owned) was unsustainable.

Ratio vs. Obiter: Ratio - where the contract confines the contractor to producing and supplying compressed air and does not entrust exploration/mining functions or tie remuneration to exploration results, the activity does not qualify as "mining service" under Section 65(105)(zzzy).

Conclusion: The activity under the impugned contracts did not amount to "mining service"; consequently the Service Tax demand (and attendant interest and penalties) confirmed under that head is not sustainable. Penalties cannot stand where tax demand itself is untenable.

Cross-reference and overall conclusion

Cross-reference: Issues 1 and 2 are interrelated - classification as manufacture (Issue 1) and the non-determinative nature of machinery ownership (Issue 2) jointly negate the applicability of Service Tax as a "mining service" (Issue 3) where the end product is compressed air specified in the Tariff.

Overall conclusion: The activities in all contracts amounted to manufacture of compressed air (an excisable good at nil rate); ownership of HPMACs by the contractee is not a decisive factor to attract Service Tax; consequently the Service Tax, interest and penalties imposed under the "mining service" head were set aside.
