Questions of Law
  • Whether direct-site duty-paid bought-out parts must be included in the value of CKD boilers for excise assessment?
  • Whether a show-cause notice issued under the extended limitation proviso to Section 11A(1) is valid without proof of wilful suppression?
Ratio Decidendi
  • Section 3 of the Central Excise Act, 1944 imposes duty on manufacture of movable excisable goods; Section 4 prescribes valuation once excisability is established.
  • A boiler assembled with civil‐engineering works into a permanently embedded steam-generating plant ceases to be “goods” under movability/marketability test and thus is not excisable.
  • Direct-site purchased parts cannot be separately brought into assessable value if the resultant product is an immovable installation.
  • Invocation of the extended five-year limitation under Section 11A(1) proviso requires evidence of wilful suppression of facts; mere non-inclusion of value does not suffice.
  • Excess collection of duty from the buyer does not establish liability; recovery must follow Section 11D if duty is collected without authority.

Logic / Jurisprudence / Authorities Relied Upon by Court
  • Distinction between Section 3 (charging) and Section 4 (valuation) of the Excise Act.
  • Nature and concept of excise as a levy on manufacture of movable goods.
  • Movability/marketability test—goods embedded into earth become immovable.
  • Requirement of wilful suppression under Section 11A(1) proviso.
  • Section 11D recovery mechanism for unauthorized duty collections.
Facts as Summarised by the Court
  • Assessee contracted to supply a 50 TPH steam-generating boiler in CKD condition; civil and mechanical erection was performed on-site.
  • Bought-out items (fans, pumps, valves, etc.) were duty-paid by vendors and delivered direct to site.
  • Revenue issued SCN alleging undervaluation by exclusion of bought-out parts’ cost and invoked five-year limitation for wilful suppression.
  • CESTAT held that direct-site parts were essential and lifted their value into the assessable value of the CKD boiler.
  • Supreme Court reversed, finding the final plant immovable—therefore non-excisable—and SCN invalid without proof of wilful suppression.

What’s New / What Lawyers Should Note

  • Confirms that a plant assembled and permanently embedded on-site is not “goods” and is not excisable under the Central Excise Act.
  • Reinforces that Section 4 valuation provisions cannot be used to confer excisability; Section 3 charge first must be triggered on a movable product.
  • Clarifies that direct-site duty-paid parts cannot be added to assessable value when assembly results in an immovable installation.
  • Emphasises that invoking the five-year extended limitation under Section 11A(1) proviso requires evidence of wilful misstatement or suppression with intent to evade excise duty.
  • Advises that any excess duty collected from a buyer must be recovered under Section 11D, not by re-characterizing sale proceeds as assessable value.

Summary of Legal Reasoning

  1. Charge vs. Valuation Distinction: Section 3 imposes the excise duty on manufacture of movable goods; Section 4 prescribes the method of valuation once liability under Section 3 is established (Bombay Tyre).
  2. Movability/Marketability Test: Goods affixed or embedded to earth through erection and civil works lose movability and cannot meet the prerequisite for excise liability (Quality Steel; Mittal; Sirpur Paper Mills).
  3. Contract Analysis: Boiler components and duty-paid parts were assembled on-site using concrete, bricks, and civil engineering, creating a permanently embedded plant—an immovable installation, not excisable goods.
  4. Inclusion of Bought-out Parts: As the resultant product is not a movable good, its value cannot derive from the total contract or transaction value under Section 4, so direct-site parts cannot be added to the assessable value.
  5. Invalidity of Extended Limitation SCN: Proviso to Section 11A(1) requires deliberate suppression or misstatement with intent to evade—absent such proof, the SCN issued after one year but within five is invalid (Pahwa Chemicals; Continental Foundation JV).
  6. Recovery of Unauthorized Collections: Even if duty were collected from the buyer on these parts, recourse must lie under Section 11D, not by altering valuation of the final product.

Arguments by the Parties

Petitioner (Assessee):

  • Contractual scope limited to CKD supply; no obligation to erect; actual erection by buyer’s engineers.
  • Bought-out items were supplied duty-paid by vendors and never entered the factory; no CENVAT credit was claimed.
  • Boiler becomes an immovable asset upon civil erection; not “goods” under the Excise Act.
  • Inclusion of direct-site parts in assessable value contradicts the nature of a charging provision; Section 4 cannot confer excisability.
  • Extended limitation cannot apply absent proof of wilful suppression; immovability plea was raised at first instance before lower authorities.

Respondent (Revenue):

  • Manufacture occurs upon assembly of CKD parts and bought-out items at site; taxable event completed before embedment.
  • Amended Section 4 transaction value (contract price) includes bought-out parts and is sole consideration.
  • Bought-out items are functionally “parts” (not mere accessories) essential to the boiler’s operation.
  • Assessee recovered CENVAT credit and duty reimbursement from the buyer; reflects inclusion in transaction value.
  • Extended five-year limitation applicable due to wilful suppression of material facts.

Factual Background

Between April and June 2000, the assessee cleared boiler parts from its factory in CKD condition, while certain essential parts were purchased duty-paid by third-party vendors and delivered directly to site. The revenue issued a show-cause notice alleging undervaluation by excluding the cost of these parts from the assessable value of the boiler and invoked the five-year extended limitation for wilful suppression. After two levels of appeal quashed the demand, the CESTAT reversed, including direct-site parts in valuation. The Supreme Court granted special leave, disputing excisability and the validity of the extended-period notice.

Statutory Analysis

  • Section 3, Central Excise Act, 1944: Charging provision for duty on manufacture of excisable goods—goods must be movable.
  • Section 4, Central Excise Act, 1944: Valuation provision prescribing “transaction value” methodology; not a charging section.
  • Section 11A(1), Central Excise Act, 1944: Limitation for SCNs—one year normally; five years if fraud, collusion, wilful misstatement or suppression with intent to evade.
  • Section 11D, Central Excise Act, 1944: Recovery mechanism for duty collected without authority from buyers.

Alert Indicators

  • ✔ Precedent Followed – Affirms Supreme Court’s movability/marketability test.
  • 📅 Time-Sensitive – Clarifies strict requirements for invoking five-year limitation.
