Could Rajasthan’s Mining Enforcement Affect Indian Sandstone Supply to the UK?

Rajasthan Quarry Enforcement and Indian Sandstone Supply: Developments from 2025 to 2026

Rajasthan is one of India’s most important natural-stone-producing states and a major source of sandstone supplied to the United Kingdom. From 2025 through the first half of 2026, state authorities introduced tighter mining rules, adjusted mineral royalty rates, investigated illegal extraction and took action involving inactive or potentially non-compliant mining operations.

These measures are part of an evolving policy framework and have begun to affect sections of the sandstone supply chain. Observed impacts include changes in raw-material availability, quarry operating costs and factory purchasing conditions. The greatest pressure appears to fall on businesses that depend heavily on low-cost, irregular, undocumented or externally purchased raw sandstone.

This does not mean that Rajasthan has closed its sandstone industry. Properly licensed quarries and compliant processing factories continue to operate. However, the regulatory direction, as reflected in available documents and reporting, is moving towards tighter traceability, higher compliance costs and greater reliance on approved quarry sources.

When Did the Latest Changes Begin?

There was no single date on which Rajasthan suddenly closed illegal mines and allowed only licensed mines to operate. The more accurate picture is a sequence of regulatory changes, royalty revisions and enforcement actions that developed throughout 2025 and became more visible towards the end of 2025 and in early 2026.

January 2025: Revised Rules for Inactive Mining Leases

The Rajasthan Minor Mineral Concession (Amendment) Rules were published on 3 January 2025. Among other changes, the rules introduce provisions under which a mining lease or quarry licence may lapse when production and mineral dispatch have not started within two years, or where operations have stopped continuously for two years, subject to the procedures and exceptions contained in the rules.

These provisions provide the authorities with a clearer framework for dealing with dormant mining rights. Leaseholders may be required to resume compliant production, provide an acceptable explanation for continued inactivity or face possible loss of the concession in accordance with the rules.

The rule changes reduce the ability of dormant leases to remain indefinitely outside productive use. They also increase pressure on mine operators to maintain valid documentation, demonstrate activity and comply with the conditions attached to their concessions.

July 2025: Notices Issued to Inactive Mining Leaseholders in Bundi

In July 2025, The Times of India reported that the Rajasthan mining department had identified a substantial number of long-inactive leaseholders in Bundi district and had begun issuing notices to many of them.

The report stated that 149 of the district’s 433 mines had remained inactive for a considerable period, with a notable concentration in the Dabi and Baran areas. Dabi is an established sandstone-producing area within the wider Kota–Bundi stone belt.

The authorities warned that leases could be cancelled if operations were not resumed. Some mine operators reportedly argued that weak export demand, low stone prices and difficult trading conditions had made certain sites commercially unviable.

Such actions potentially reduce the number of dormant concessions that can remain available as backup sources of stone. They may also increase uncertainty for independent processing factories that purchase raw blocks from multiple quarry operators rather than controlling their own quarry supply.

July 2025: Higher Royalty Charges on Sandstone

Separate reporting in July 2025 indicated that Rajasthan increased mineral royalty rates, including rates applying to sandstone. According to The Times of India, the royalty on processed sandstone was raised from ₹240 to ₹320 per tonne, while rates on certain categories of raw sandstone were also revised.

This increase directly affects the regulated cost structure of legitimate quarrying, mineral dispatch and sandstone processing. Quarry operators, mineral dispatchers and processing businesses subject to the revised royalty classifications must account for the higher statutory charge when pricing raw blocks, processed stone and finished paving.

The royalty increase therefore raises the regulated cost base of sandstone production. The extent to which it affects each finished patio pack depends on the quarry source, applicable mineral classification, stone yield, processing efficiency and the commercial arrangements between the quarry, factory and exporter.

The final cost of a patio pack is also influenced by:

• the quality and usable size of the original sandstone block;
• cutting, calibration and hand-finishing costs;
• breakage, wastage and manufacturing yield;
• wooden crates, packaging and inland haulage;
• factory labour, electricity and diesel;
• container freight, insurance and port charges;
• currency movements between sterling, the US dollar and the Indian rupee.

December 2025: Drone Evidence and Action in Bhilwara

In December 2025, Rajasthan’s Department of Mines issued notices to eight mining leaseholders in Bhilwara district after a drone survey reportedly identified substantial discrepancies between permitted operations and actual extraction.

The allegations included mining beyond approved lease boundaries and possible misuse of mineral transit permits. The quantities and potential penalties reported in the press were described as large. The leaseholders were given an opportunity to respond, and the allegations should not be treated as final judicial findings.

This action illustrates that enforcement has moved beyond roadside vehicle checks. Authorities can increasingly compare:

• approved quarry boundaries;
• drone and survey evidence;
• declared production volumes;
• royalty records;
• mineral transport permits and dispatch documentation.

This level of monitoring makes it more difficult for licensed operations to supplement production with stone extracted from adjoining or unapproved land. It also increases the importance of accurate boundary control, production records and mineral transport documentation.

January 2026: Rajasthan High Court Reviews Drone-Survey Procedure

In January 2026, the Rajasthan High Court considered a separate Bhilwara case involving a recovery notice based on a drone survey that had been conducted without prior notice to the affected mining leaseholder.

The court ruled that mining surveys, including drone-assisted surveys, must follow the principles of natural justice. It set aside the disputed recovery notice because the leaseholder had not been given advance notice of the survey on which the action was based.

The court nevertheless allowed the state government and mining department to conduct a fresh survey after following the proper procedure. The ruling therefore did not prohibit drone-assisted mining enforcement or establish that the underlying quarry activity was compliant. Instead, it confirmed that drone evidence, recovery demands and penalties remain subject to procedural safeguards and judicial review.

This distinction is important. Drone surveys can provide authorities with detailed evidence concerning quarry boundaries and excavation volumes, but the evidence must be collected and used through a lawful process before it can support final recovery or penalty proceedings.

January 2026: Alleged Illegal Sandstone Mining Investigated in Kota

One of the more directly relevant reports for the Kota sandstone area appeared in January 2026. The Times of India reported that the Rajasthan Forest Department had sent an inspection team to the Mandana reserve forest area of Kota district following allegations of extensive illegal sandstone extraction.

The reported activity included deep quarry pits, heavy machinery and blasting within protected forest land. The Forest Department stated that an inspection had taken place and that a factual report would be prepared before further action was determined.

The inspection and the allegations surrounding it demonstrate that alleged illegal sandstone extraction remains an active enforcement and environmental concern within parts of Kota district. Action against proven extraction from protected or unauthorised land would reduce the amount of unrecorded material available to local traders and smaller processing operations.

At the time of the report, however, the inspection process had not produced a publicly reported final determination concerning every allegation. The investigation should therefore not be presented as a completed judicial or regulatory finding against every party associated with the area.

It also does not mean that every quarry in the wider Kota region has been closed, nor does it establish that every product sold under a Kota-related trade description came from an illegal source.

What Is the Rajasthan Government Trying to Achieve?

Taken together, recent amendments, enforcement reports and auction activity suggest that the Rajasthan authorities are pursuing several objectives at the same time:

• reducing illegal extraction from forest land and unauthorised areas;
• preventing mining outside approved lease boundaries;
• improving royalty collection and mineral-tracking records;
• bringing inactive leases back into production or cancelling unusable concessions;
• reallocating mineral resources through formal auctions;
• increasing state mining revenue while retaining a regulated stone industry.

The policy is not a general prohibition on sandstone mining. Rajasthan continues to support formal mineral auctions, licensed quarrying and legitimate investment.

The direction is towards a more closely monitored industry in which production is increasingly concentrated among operators that can demonstrate valid quarry rights, correct royalty payments, compliant transport records and acceptable environmental controls.

This policy direction appears to be increasing the compliance burden on the sector and is likely to influence the price and availability of legally documented sandstone over time, although the extent of its impact will depend on how enforcement, court decisions, auctions and market responses evolve.

How Is Enforcement Affecting Sandstone Production?

Reduced Availability of Informally Sourced Raw Stone

Many independent sandstone processing factories do not own quarries. They purchase rough blocks, slabs or partly processed material from local quarry operators, brokers and regional stone traders.

Tighter enforcement reduces the availability of raw stone originating from unauthorised pits, protected land, excessive extraction or areas outside approved quarry boundaries.

Factories that previously depended heavily on these lower-cost or irregular supply routes now face tighter purchasing conditions and greater dependence on fully documented quarry sources.

Factories with direct quarry access, long-term supply contracts or substantial stocks of compliant raw material generally report stronger resilience. These constraints do not affect all factories uniformly; operations with stronger quarry-backed supply or higher levels of documented stock tend to experience more stability than those relying heavily on irregular purchasing.

Greater Pricing Power for Compliant Quarry Operators

As irregular supply becomes harder to access, compliant quarry operators hold a stronger commercial position in many areas. Based on PSU’s supplier discussions and purchasing observations, this appears to have increased their pricing influence for sound, high-yield raw material, particularly where factories require:

• large and relatively sound sandstone blocks;
• high production yields of 900 x 600 mm paving;
• consistent colour selection;
• tighter thickness tolerances;
• premium hand-cut, tumbled or sawn finishes;
• large repeat orders from a consistent geological source.

This does not create a complete monopoly. Rajasthan still contains many quarry operators and processing centres, and market competition between different producers remains significant. However, licensed producers with reliable reserves and strong documentation may hold greater pricing influence within the legitimate supply chain where suitable raw stone is limited.

Higher Documentation and Compliance Costs

Legal production involves more than obtaining a quarry lease. Depending on the site and operation, costs may include:

• mineral royalty payments;
• environmental compliance;
• approved mineral transport documentation;
• quarry and boundary surveying;
• vehicle and dispatch tracking;
• safety controls;
• land-use and forest restrictions.

These requirements increase the operating cost of legitimate production. Even where physical stone remains available, compliant quarrying and transport are more expensive and administratively demanding than irregular or undocumented extraction.

Which UK Sandstone Products Are Most Exposed?

The effects are not identical across every sandstone product. Exposure depends on the quarry location, raw-material quality, factory stock, product dimensions and the level of colour or surface selection required.

Large Single-Size Paving

Large-format paving requires sound blocks with sufficient usable surface area. Cracks, bedding weaknesses and natural defects reduce the production yield of 900 x 600 mm slabs more severely than smaller mixed sizes.

Restrictions on the supply of suitable high-yield blocks therefore place more cost pressure on large single-size paving than on products that can be manufactured from smaller stone sections.

Highly Selected Colour Ranges

Products sold within narrow colour parameters require additional sorting, selection and rejection at the factory.

When raw-block availability becomes tighter, factories need to purchase and process more material to produce the same quantity of highly selected paving. This increases the cost of ranges requiring consistent grey, green, buff or lightly blended colour characteristics.

Very Low-Priced Imported Sandstone

Very low historic sandstone prices become harder to maintain where factories must rely on fully documented quarry sources, revised royalty payments and compliant mineral transport.

This does not mean that every low-priced sandstone product is illegally sourced. Competitive pricing may also result from:

• direct quarry ownership;
• large-volume purchasing;
• efficient manufacturing;
• lower factory overheads;
• older raw-material or finished-stock inventory;
• favourable exchange rates.

Price alone is not evidence of illegal extraction. However, the gap between compliant production costs and the lowest historic market prices has narrowed.

What Does This Mean for the UK Paving Market?

The UK paving market is already operating against a backdrop of higher quarry compliance costs, revised royalty charges, variable raw-material availability and continued international freight uncertainty. These factors interact with broader global trade conditions rather than in isolation.

Current information does not point to a complete shortage of Indian sandstone. Instead, available evidence, PSU supplier quotations and replacement-stock assessments suggest that any impact is more likely to take the form of gradual and uneven adjustments in replacement-stock costs, affecting some colours, slab sizes and suppliers more than others.

Based on PSU’s own commercial supply-chain information, possible market effects include, and have in some cases already included:

• higher factory quotations for selected sandstone products;
• longer production lead times for large or tightly selected slabs;
• reduced availability of certain colours or specialist finishes;
• more frequent factory price revisions;
• shorter quotation-validity periods;
• greater differences between quarry-backed manufacturers and trading factories;
• greater importance placed on traceability and reliable raw-material contracts.

These observations should not be interpreted as an official measurement of the whole Indian or UK sandstone market. Different importers may hold different levels of stock, use different factories, purchase from different quarry regions and negotiate under different contractual arrangements.

UK importers holding substantial domestic stock may not need to adjust prices immediately. Any effect becomes more visible when existing inventory is sold and replacement containers are ordered at updated quarry, factory and freight costs.

Mining Enforcement Is Not the Only Cost Pressure

Not every sandstone price movement can be attributed to Rajasthan’s mining policy. Ocean freight remains exposed to geopolitical conflict, Red Sea and Suez Canal routing changes, fuel costs, insurance risks and temporary carrier surcharges.

British and international reporting has documented periods in which Asia–Europe cargo was diverted around the Cape of Good Hope. These diversions increased sailing times, vessel utilisation, fuel consumption and pressure on available shipping capacity.

More recent reporting has also discussed cautious or partial returns to the Suez and Red Sea route. Where security conditions permit, a return to shorter routes can reduce some transit-time and freight pressure. However, the shipping position remains exposed to further disruption and policy changes.

Quarry costs and shipping costs can therefore move independently. Higher sandstone production costs may be partly offset by lower freight, while a temporary reduction in factory prices may be outweighed by increased ocean transport, insurance or port-related charges.

What Can Be Stated with Confidence?

Supported by Available Evidence

• Rajasthan amended its minor-mineral rules in January 2025.
• The revised framework included provisions relating to inactive mining leases and quarry licences.
• Bundi authorities issued notices to a substantial number of inactive leaseholders during 2025.
• Rajasthan raised royalty charges affecting sandstone during 2025.
• Drone-assisted investigations identified alleged mining irregularities in Bhilwara in December 2025.
• The Rajasthan High Court subsequently confirmed that drone-assisted surveys and related recovery proceedings must comply with procedural safeguards, including prior notice.
• The Forest Department investigated reported illegal sandstone extraction in Kota’s Mandana reserve forest in January 2026.
• These measures have increased regulatory pressure on the Rajasthan stone industry.
• Higher royalty and compliance requirements have raised the regulated cost base of legally documented sandstone production.
• Restrictions on irregular supply are increasing the commercial importance of stone obtained from properly licensed quarry operators.
• Based on PSU supplier quotations and replacement-stock assessments, these changes are beginning to affect some factory quotations and UK replacement-stock costs.

Points That Should Not Be Overstated

• not every sandstone mine around Kota, Bundi or Bhilwara has been closed;
• not every allegation reported following a drone survey or forest inspection has become a final judicial finding;
• not every UK sandstone price increase is caused by quarry enforcement;
• not every Indian factory or exporter faces the same level of disruption;
• no verified national percentage decline in legal sandstone production has been established;
• the evidence does not support a permanent nationwide shortage of Indian sandstone;
• PSU supplier quotations should not be interpreted as a complete statistical measure of the wider UK market;
• no particular UK product should be described as illegally sourced without specific evidence.

PSU Conclusion and Our Supply-Chain Position

The available evidence points to a tightening of mining regulation, environmental oversight, royalty collection and quarry-boundary enforcement across parts of Rajasthan.

These measures are changing the operating environment for sandstone quarries, factories and raw-material traders. They appear to be increasing the value of licensed quarry access, documented transport and reliable raw-block inventories.

Factories that depend heavily on fragmented or irregular purchasing appear more exposed to supply disruption and cost increases than those with stable access to licensed quarries, stronger documentation and sufficient raw-material stocks.

Paving Slabs UK works through long-standing supply relationships with established Indian sandstone producers. This structure gives us stronger practical visibility over supplier production planning, replacement-stock quotations and container scheduling than would normally be available through one-off or short-term spot purchasing.

Our supply structure does not remove every market risk. Quarry costs, freight rates, exchange rates and production conditions can still change. However, direct and established supplier relationships provide greater continuity and planning visibility than relying entirely on short-term purchases from unknown trading sources.

For UK buyers, the practical implication of this assessment is not that Indian sandstone is disappearing, but that the cost and reliability of compliant supply are evolving. In this environment, importers and manufacturers with stable quarry relationships, established production capacity and sufficient inventory may be better positioned to manage periods of disruption than those relying exclusively on opportunistic short-term purchases.
