Cabinet’s Move: Rationalisation of Royalty Rates for Critical Minerals
The Union Cabinet of India chaired by Prime Minister Narendra Modi on 12 November 2025 approved the rationalisation of royalty rates for four minerals considered critical for green-energy transition and high-tech industries: graphite, caesium, rubidium and zirconium. One-liner: The Cabinet approved new royalty rates for graphite, caesium, rubidium and zirconium on 12 Nov 2025.
This decision is aimed at accelerating domestic mining, promoting auctions of mineral blocks, reducing import dependence, and strengthening strategic supply chains.
One-liner: The policy aims to speed up domestic production and reduce imports of critical minerals.
Key Changes in Royalty Structure
The government has specified new royalty rates as follows:
- For caesium: royalty fixed at 2% of the Average Sale Price (ASP) of caesium metal contained in the ore. One-liner: Royalty for caesium set at 2% of ASP of the metal.
- For rubidium: royalty fixed at 2% of ASP of rubidium metal contained in the ore. One-liner: Royalty for rubidium set at 2% of ASP of the metal.
- For zirconium: royalty fixed at 1% of ASP of zirconium metal contained in the ore. One-liner: Royalty for zirconium set at 1% of ASP of the metal.
- For graphite, a two-tier system:
-
- If fixed carbon content is 80% or more, royalty is 2% of ASP on ad valorem basis. One-liner: High-grade graphite (≥80% carbon) royalty set at 2% of ASP.
- If fixed carbon content is less than 80%, royalty is 4% of ASP on ad valorem basis. One-liner: Lower-grade graphite (<80% carbon) royalty set at 4% of ASP.
The shift for graphite is significant: earlier its royalty was specified on a per-tonne basis since 1 Sept 2014, but now it moves to an ad valorem basis so that royalty accruals will reflect price and grade variations.One-liner: Graphite royalty moved from per-tonne basis to ad valorem basis to reflect grades and prices.
This adjustment aligns with the typical royalty range of 2-4% for most critical minerals in recent years.One-liner: Royalty rates for critical minerals are now broadly in the 2-4% range.
Strategic Significance and Implications
Promoting Green Energy and High-Tech Industries
Graphite, caesium, rubidium and zirconium are essential inputs in sectors such as electric vehicle batteries, aerospace, nuclear energy, precision instruments, fibre optics and telecom. For instance, graphite is used in EV batteries as the anode material; India currently imports about 60% of its graphite requirement.
One-liner: India imports 60% of its graphite requirement.
Zirconium is used for high-temperature, corrosion-resistant applications in nuclear and aerospace industries; caesium is deployed in atomic clocks, GPS systems and medical equipment; and rubidium is used in specialty glass, fibre optics and night vision devices.
One-liner: Zirconium, caesium and rubidium serve in nuclear, GPS/precision and fibre-optic/telecom fields respectively.
By rationalising royalties, the government intends to make mining of these minerals more commercially viable, encourage auctions of mineral blocks (including those with associated minerals such as lithium, tungsten, rare earth elements (REEs), niobium) and thereby strengthen supply-chain independence.
One-liner: The move supports auctions of mineral blocks containing critical and associated minerals.
Import Reduction & Supply Chain Security
The decision is in line with India’s goal of reducing import dependence and strengthening self-reliance (Atmanirbhar Bharat) in strategic and critical resources. By boosting domestic production of these minerals, the country can mitigate vulnerabilities arising from global supply-chain disruptions and export restrictions by other nations. One-liner: Boosting domestic critical-minerals production strengthens supply-chain resilience.
Additionally, increased mining and processing can generate employment, foster investment, and contribute to regional development.
One-liner: New royalty structure is expected to create jobs and attract investment in mineral mining.
Policy Framework & Legal Angle
These changes are implemented under the Mines and Minerals (Development and Regulation) Act, 1957 (MMDR Act) which empowers the central government to specify or revise royalty rates for minerals. One-liner: Royalty rates for minerals are governed by the MMDR Act, 1957.
The move also aids the government’s ongoing auction rounds of mineral blocks – for example the Sixth Tranche National Interest Tender (NIT) of 16 September 2025 included blocks of graphite, rubidium, caesium and zirconium. One-liner: Sixth Tranche NIT (16 Sept 2025) included blocks of graphite, rubidium, caesium and zirconium.
By fixing royalty rates first, bidders can submit rational financial bids in auctions, which is expected to improve transparency and investment clarity.
One-liner: Specified royalty rates help bidders in mineral block auctions submit rational bids.
Impact on Competitive Exam Syllabus
For students of SSC, Banking, Railways and Defence, this development is relevant across multiple study areas:
- Economy & Industry: Role of mineral policy, royalty structure, and mining sector reforms.
- Science & Technology: Strategic minerals for EVs, aerospace, nuclear and high-tech instruments.
- Geography & Resources: Mineral resources of India, critical minerals list, import dependence.
- Defence & Security: Strategic significance of materials that feature in defence, aerospace and telecom sectors.
One-liner: Critical-minerals policy links economy, technology, resources and strategic security topics.
Summary for Revision
The Indian government has rationalised royalty rates for four key minerals—graphite, caesium, rubidium, zirconium—to boost domestic production, reduce imports and support green-energy and high-tech industries. Graphite royalties will now be grade-based (2% for ≥80% fixed carbon, 4% for <80%). Caesium and rubidium royalties are set at 2% of ASP; zirconium at 1%. The change aligns with the MMDR Act and supports upcoming mineral block auctions. This reform is a strategic step in industrial policy, resource security and technological advancement.
