Discuss how recent amendments to the MMDR Act, 1957 aim to secure India's critical mineral supply chains. What challenges remain in implementation?

Critical minerals — cobalt, lithium, gallium, rare earths — underpin defence, electronics and renewable energy, yet India remains heavily import-dependent. Successive amendments to the Mines and Minerals (Development and Regulation) Act, 1957, culminating in the MMDR (Amendment) Bill, 2026 passed by Parliament on 13 August 2026 [1], seek to build a fiscally stable and centrally coordinated regime for securing these supply chains.

How the amendments strengthen supply-chain security

• Fiscal predictability: the 2026 Act inserts a new Section 9D barring States from levying tax or cess on mineral rights and mineral-bearing land except on Centrally prescribed conditions, replacing multiple uneven levies with a uniform regime that lowers investment risk [2].
• Central regulatory locus: Section 2 is amended to bring "mineral-bearing lands" expressly under Union regulation, enabling nationally consistent parameters for strategic mineral tracts [1][2].
• Auction enablement: royalty rates for 12 critical and strategic minerals (Beryllium, Cobalt, Gallium, Indium, Tantalum, Tungsten, Vanadium and others) were rationalised, completing the exercise for all 24 such minerals and allowing first-ever Central auctions [3].
• Exploration and output push: the MMDR (Amendment) Act, 2025 allowed leaseholders to add other minerals to an existing lease and eased captive-mine sale caps, expanding recovery of associated critical minerals [1].

Implementation challenges

• Fiscal federalism friction: curbing State levies narrows powers affirmed for States over mineral rights taxation, inviting political and judicial contestation [1][2].
• Rule-making dependency: the operative conditions are to be "prescribed", so gains hinge on timely subordinate legislation [2].
• Structural gaps: exploration deficits, long clearance timelines, and absent domestic refining and processing capacity mean auctioned blocks may not translate into secure supply.

The amendments correctly shift mineral governance from a fragmented, State-by-State fiscal patchwork toward a predictable national framework. Their promise, however, will be realised only if the Centre pairs fiscal centralisation with genuine consultation and revenue-sharing assurances to mineral-rich States, and invests downstream in processing. Cooperative federalism and resource security must advance together, not at each other's cost.
