The Supreme Court has upheld the Centre’s existing methodology for calculating royalty on iron ore, rejecting a challenge that described the mechanism as an unlawful form of “royalty on royalty.”
The Court ruled that royalty, District Mineral Foundation contributions and National Mineral Exploration Trust payments may continue to form part of the sale value used for determining the Average Sale Price of iron ore.
The judgment confirms that the current computation framework is constitutionally valid and consistent with the Mines and Minerals (Development and Regulation) Act, 1957.
Kirloskar Ferrous Challenged the Rules
The petition was filed by Kirloskar Ferrous Industries Ltd.
The company challenged explanations inserted into:
- Minerals (Other than Atomic and Hydro Carbons Energy Minerals) Concession Rules, 2016
- Mineral Conservation and Development Rules, 2017
The petitioner argued that the rules artificially increased the sale value of iron ore by preventing the deduction of royalty, DMF and NMET payments.
According to the company, this resulted in royalty being calculated on a value that already included royalty-related statutory payments.
How Iron Ore Royalty Is Calculated
Under Section 9 of the MMDR Act and Entry 24 of the Second Schedule, royalty on iron ore is levied at 15% of the Average Sale Price on an ad valorem basis.
The Indian Bureau of Mines publishes the monthly ASP for different mineral grades.
The ASP is calculated using the weighted average of ex-mine sale prices reported by eligible mining operations.
This benchmark is used for calculating:
- Royalty
- Auction premiums
- District Mineral Foundation contributions
- National Mineral Exploration Trust contributions
- Other statutory mining payments
DMF and NMET Contributions
Mining lease holders are required to make additional statutory contributions linked to royalty.
For iron ore lease holders:
- DMF contribution: 10% of the royalty amount
- NMET contribution: 2% of the royalty amount
The District Mineral Foundation finances welfare and development programmes in mining-affected areas.
The National Mineral Exploration Trust supports mineral exploration and related activities.
Petitioner Alleged Cascading Burden
The petitioner argued that the rules prevented mining companies from deducting royalty, DMF and NMET payments while calculating the sale value.
According to the challenge, this meant:
- Royalty became part of the sale value.
- The inflated sale value influenced the ASP.
- Royalty was then calculated again on the enhanced ASP.
- DMF and NMET liabilities also increased accordingly.
The company argued that the structure created a cascading burden equivalent to charging “royalty on royalty.”
Centre Defended the Methodology
The Union government defended the framework and argued that it was introduced to prevent:
- Under-invoicing
- Artificial reduction of mineral prices
- Manipulation of reported sale values
- Revenue leakage
The Centre also submitted that the pricing structures of iron ore and coal are fundamentally different.
It argued that separate royalty computation mechanisms for different minerals are reasonable and legally permissible.
Supreme Court Upholds Rules
The Supreme Court rejected the challenge and held that the explanations inserted into the 2016 and 2017 Rules are legally valid.
The Court found that the provisions:
- Do not violate Article 14
- Do not violate Article 19(1)(g)
- Are consistent with Section 9 of the MMDR Act
- Do not create an unauthorised levy
- Do not amount to an unlawful revision of the royalty rate
The Bench clarified that the existing framework concerns the methodology used to determine ASP rather than an increase in the statutory rate of royalty.
Three-Year Restriction Not Applicable
The petitioner had also argued that the methodology effectively revised the royalty burden within the statutory three-year restriction period.
The Supreme Court rejected this argument.
It clarified that the restriction applies to changes in the rate of royalty, not to adjustments or explanations governing the calculation of the Average Sale Price.
Since the statutory royalty rate remains 15%, the Court held that the framework did not violate the restriction.
No New Levy Imposed
The judgment does not introduce any new tax, royalty or statutory payment.
It simply affirms the validity of the existing calculation methodology.
As a result:
- The royalty rate remains unchanged.
- DMF and NMET contribution rates remain unchanged.
- The current ASP calculation mechanism continues.
- Royalty-related payments remain included in the reported sale value.
Any change would require an amendment to the applicable law or rules.
Impact on Mining Companies
The ruling has significant financial implications for iron ore mining companies because the existing cost structure will continue.
Mining businesses must account for:
- 15% royalty on ASP
- DMF contribution linked to royalty
- NMET contribution linked to royalty
- Auction premiums where applicable
- Other statutory and operational costs
The judgment reduces uncertainty surrounding the legality of the existing framework but may preserve a comparatively higher statutory payment base for mining operators.
Implications for Government Revenue
The ruling protects the existing revenue methodology followed by the Centre and state governments.
Excluding royalty and related statutory contributions from sale value could have reduced:
- Royalty collections
- DMF contributions
- NMET funding
- Auction-linked payments
The Court’s decision therefore maintains the current revenue structure supporting mineral administration, exploration and mining-area development.
Why ASP Reporting Matters
The Average Sale Price depends on accurate sale-value reporting by mining companies.
Incorrect pricing or under-invoicing can affect:
- Government royalty revenue
- Auction premiums
- DMF collections
- NMET contributions
- Market benchmarks
Transparent mineral pricing and independent verification remain essential to prevent manipulation.
Conclusion
The Supreme Court has confirmed that the Centre’s existing iron ore royalty computation framework is constitutional and legally valid.
The Court rejected the argument that including royalty, DMF and NMET payments in the sale value creates an unlawful “royalty on royalty.”
The existing methodology will therefore continue unless Parliament or the relevant rule-making authorities amend the legal framework.
Shunyatax Global Insight
Shunyatax Global says that the judgment provides important certainty for mining companies, lenders and investors because it confirms that the current statutory payment structure will continue.
Mining businesses should incorporate royalty, DMF, NMET, auction premiums and related obligations into project valuations, cash-flow projections and mineral pricing models. Accurate ASP reporting and periodic compliance reviews are essential because even a small change in the sale-value base can materially affect mining profitability and government liabilities.
