India begins to China-proof its infra push after the TBM shock
India is accelerating efforts to localise the manufacturing of mining and construction equipment, including tunnel boring machines (TBMs), after Chinese export delays disrupted supplies for key infrastructure projects
A proposed incentive scheme aims to reduce import dependence, strengthen domestic supply chains, and boost manufacturing and exports of such heavy equipment
The push is linked to India's broader infrastructure, mining, and critical minerals development plans over the coming decades
State-run defence and engineering major BEML has begun work on indigenous TBM design, engaging global design-consultancy firms to develop machines across a range of tunnel diameters
Tunnel Boring Machines (TBMs) and Import Dependence
A tunnel boring machine is a specialised piece of heavy engineering equipment used to excavate tunnels with a circular cross-section through soil and rock, widely deployed in metro rail, high-speed rail (bullet train), road, and water-supply tunnelling projects. India's rapidly expanding metro and rail tunnelling programme has historically relied on TBMs imported or manufactured under licence by global majors (from countries including Germany, China, and Japan), leaving supply chains vulnerable to geopolitical disruption.
Key Details
- TBM types include Earth Pressure Balance (EPB) machines for soft soil and slurry/rock TBMs for harder geology
- India's expanding metro networks, the Mumbai-Ahmedabad High Speed Rail corridor, and various water and hydro tunnels are the principal demand drivers for TBMs
- BEML (Bharat Earth Movers Limited), a Ministry of Defence public sector undertaking, has floated proposals to indigenously design and manufacture TBMs spanning roughly 6 to 16.5 metres in diameter, in consultation with overseas design-consultancy partners
The disruption in TBM supplies from China is presented in the article as the trigger event pushing India toward indigenous capability in a capital-goods segment it has long imported.
Production-Linked Incentive (PLI) Framework
The Production-Linked Incentive (PLI) scheme is the Union Government's principal instrument for incentivising domestic manufacturing across strategic sectors. It offers financial incentives — typically calculated as a percentage of incremental sales of goods manufactured in India over a base year — to companies that scale up domestic production, aiming to reduce import dependence and build export capacity.
Key Details
- PLI schemes span sectors including electronics, pharmaceuticals, telecom equipment, automobiles and auto components, advanced chemistry cell (ACC) batteries, and rare-earth permanent magnets (REPM)
- The REPM Manufacturing Scheme, approved in 2025 with an outlay of roughly ₹7,280 crore, is a recent example of a PLI-style scheme aimed at reducing reliance on Chinese rare-earth magnet supplies
- Mining and construction equipment manufacturing, referenced in this article, would be a newer addition to this incentive architecture, targeting capital goods rather than consumer or intermediate goods
The "proposed incentive scheme" for mining and construction equipment described in the article follows the same PLI logic already used for batteries and rare-earth magnets — using fiscal incentives to de-risk a China-dependent supply chain.
National Critical Mineral Mission (NCMM)
The National Critical Mineral Mission was approved by the Union Cabinet in January 2025 to build a resilient, self-reliant value chain for critical minerals — covering exploration, mining, beneficiation, processing, and recycling — that are essential inputs for clean-energy technologies, electronics, and defence manufacturing.
Key Details
- Total outlay: approximately ₹34,300 crore over seven years, comprising ₹16,300 crore of government expenditure and an expected ₹18,000 crore of investment by public sector undertakings
- Nodal ministry: Ministry of Mines
- A linked Incentive Scheme for Promotion of Critical Mineral Recycling, with a ₹1,500 crore outlay, had 58 companies approved as eligible participants by May 2026
- The Mission also proposes fast-track regulatory clearances for critical mineral mining and exploration projects
The article frames equipment localisation as part of the same strategic push as the NCMM — reducing China-dependence not just in mineral supply but in the mining and construction machinery needed to extract and process those minerals domestically.
China's Export Leverage and India's Diversification Response
China has periodically restricted exports of strategically sensitive goods — including rare-earth magnets, fertilisers, and, per this article, tunnel boring machines — citing regulatory or national-security grounds. Such restrictions have repeatedly exposed the concentration risk in India's capital-goods and critical-input supply chains.
Key Details
- Reports from mid-to-late 2025 indicated China had begun easing some of these curbs on rare-earth magnets, fertilisers, and TBM exports to India following bilateral engagement
- India's policy response mirrors its broader "Atmanirbhar Bharat" (self-reliant India) approach — combining PLI-style fiscal incentives, mission-mode programmes (like the NCMM), and public-sector-led indigenisation (as with BEML's TBM initiative)
- This is analogous to India's earlier response to Chinese dominance in electronics components and active pharmaceutical ingredients (APIs), where PLI schemes were similarly used to build domestic capacity
The "TBM shock" referenced in the article's framing is one instance of a recurring pattern — supply-chain coercion from a dominant single-country supplier prompting a diversification and localisation response from India.
- National Critical Mineral Mission: Cabinet-approved January 2025; total outlay ~₹34,300 crore over seven years (₹16,300 crore government + ~₹18,000 crore expected PSU investment)
- Incentive Scheme for Promotion of Critical Mineral Recycling: ₹1,500 crore outlay; 58 companies approved as eligible (as of May 2026)
- Rare Earth Permanent Magnet (REPM) Manufacturing Scheme: ~₹7,280 crore outlay, approved 2025
- BEML's proposed indigenous TBM range: approximately 6 to 16.5 metres in diameter
- Nodal ministries involved in the broader critical-minerals and equipment localisation push: Ministry of Mines, Ministry of Housing and Urban Affairs (for urban tunnelling/metro use-cases), Ministry of Heavy Industries (for capital-goods PLI schemes)
