CENVAT Credit on Inputs Procured Through Contractors and Effect of Service Tax Abatement: CESTAT Chandigarh Ruling in HPCL Mittal Energy Limited

1. Background and Context

The decision in HPCL Mittal Energy Limited Vs Commissioner of Central Excise & Service Tax (CESTAT Chandigarh) deals with a recurring controversy in excise and service tax:

  • Can a manufacturer claim CENVAT credit on goods procured and used by contractors within the manufacturer’s premises?
  • What happens when the contractor opts for abatement under the Works Contract Composition Scheme?
  • When can the extended period of limitation be validly invoked to deny credit?

The case involves a large refinery project where extensive fabrication of storage tanks and mechanical piping was undertaken through contractors. The Tribunal’s ruling provides important guidance on CENVAT credit entitlement where multiple parties are involved in a works contract chain, and on how abatement interacts with credit under the CENVAT Credit Rules, 2004.

2. Essential Facts

M/s HPCL Mittal Energy Ltd. (HMEL) operates a refinery producing:

  • Polypropylene
  • LPG
  • Naphtha
  • Motor spirit
  • Kerosene
  • ATF
  • Diesel
  • Turpentine oil
  • Hexane
  • Coke and other petroleum products

For installation and fabrication of storage tanks and mechanical piping, HMEL engaged two contractors:

  • M/s Bridge & Roof Co. (India) Ltd.
  • M/s Artson Engineering Ltd.

The material flow and tax positions were as follows:

  1. Materials supplied by HMEL (free of cost to contractors)

    • Stainless steel sheets, plates, valves, bolts and similar items.
    • These were directly procured by HMEL and sent to the contractors for use at HMEL’s refinery.

  2. Materials procured by contractors

    • Tools, tackles, plants, equipment and other inputs required for fabrication.
    • Contractors purchased these in their own name but the invoices mentioned HMEL as consignee, and the goods moved into HMEL’s premises.
    • HMEL reimbursed the taxes (excise duty / service tax, as applicable) paid on these items to the contractors.

  3. CENVAT credit pattern

    • HMEL availed CENVAT credit on:
      • Inputs purchased directly by HMEL; and
      • Inputs procured by the contractors but delivered to HMEL’s premises with HMEL shown as consignee.

  4. Departmental objection and proceedings

    • On audit, the department took the view that inputs procured by the contractors were inputs of the contractors, not of HMEL.
    • Two show cause notices were issued alleging wrongful availment of CENVAT credit:
      • SCN dated 02.05.2013 for period 01.04.2008 to 07.03.2013 demanding CENVAT credit of Rs. 10,68,46,038.
      • SCN dated 25.09.2013 for period 01.04.2009 to 28.04.2012 demanding CENVAT credit of Rs. 31,99,88,570.
    • Both SCNs invoked interest and equal penalty, relying on the extended period under Section 11A of the Central Excise Act and Section 73 of the Finance Act.
    • The adjudicating authority confirmed the demands through Orders‑in‑Original dated 12.03.2014 and 30.05.2014, denying credit, interest, and penalty.
    • HMEL filed appeals before CESTAT Chandigarh.

3. Issues Before the Tribunal

The Tribunal framed and considered the following key questions:

  1. CENVAT credit entitlement
    Whether a manufacturer can avail CENVAT credit on inputs:

    • Purchased by the manufacturer itself, and
    • Procured by contractors but received in the manufacturer’s premises and used for fabrication of capital goods/civil and structural works,

    when such capital goods and structures are used:

    • In manufacture of excisable final products, or
    • In providing taxable output services,

    in two distinct situations:

    • Where the contractor has not availed any abatement under the Works Contract Scheme.
    • Where the contractor has availed abatement/composition under the Works Contract (Composition Scheme for Payment of Service Tax) Rules, 2007.

  2. Extended period of limitation
    Whether the department was justified in invoking the extended period on grounds of suppression/misstatement, thereby sustaining the demands beyond the normal limitation period.

The Tribunal analysed the following provisions:

  • Rule 2(k) – definition of input under the CENVAT Credit Rules, 2004 (both pre and post 01.04.2011).
  • Rule 2(a) – definition of capital goods.
  • Rule 3 – availment of CENVAT credit on inputs and capital goods.
  • Rule 4 – conditions for availing CENVAT credit (timing and receipt of inputs).
  • Rule 9 – documentary requirements for taking credit (invoices, consignment details, etc.).
  • Rule 2A of the Service Tax (Determination of Value) Rules, 2006 – valuation of works contract services.
  • Works Contract (Composition Scheme for Payment of Service Tax) Rules, 2007 – abatement scheme and bar on availment of CENVAT credit by the service provider.
  • Section 11A of the Central Excise Act and Section 73 of the Finance Act – recovery of duty/tax and limitation.
  • Provisions relating to interest and penalties under the CENVAT Credit Rules, Section 11AC of the Central Excise Act and Section 78 of the Finance Act.

5. Arguments of the Assessee

5.1 Credit eligibility on inputs

HMEL argued that:

  • The goods in dispute qualify as “inputs” within Rule 2(k):

    • They are used for construction/fabrication of storage tanks, mechanical pipelines and similar installations within HMEL’s premises.
    • These installations are essential for manufacturing the refinery’s final petroleum products and thus have a direct nexus with production.

  • All the conditions for availing CENVAT credit stood fulfilled:

    1. Inputs were received in the factory/registered premises.
    2. Duty was duly paid on such inputs.
    3. HMEL, being a manufacturer of final products (and in one appeal, a provider of output services), used these inputs in or in relation to manufacture/provision of services.
    4. Invoices contained all particulars mandated under Rule 9, with HMEL named as consignee for contractor‑procured items.

  • The incidence of duty was borne by HMEL, not by the contractors. Contractors, as per their confirmations, had not claimed CENVAT credit on these inputs.
