Cement Plant Limestone Royalty + DMF + NMET Cost Calculator

The Mines and Minerals (Development and Regulation) Act 1957 is the parent statute governing every mineral concession in India, including the limestone mining leases that feed every integrated cement plant. Three separate statutory levies attach to every tonne of limestone extracted. First, the royalty, notified in the Second Schedule to the MMDR Act 1957 read with the state-specific notification, is a per-tonne charge payable to the state government of the state in which the mining lease is located. The current limestone royalty rate is a rupees-per-tonne figure that varies modestly by state — Rajasthan, Madhya Pradesh, Karnataka, Andhra Pradesh, Gujarat, Tamil Nadu and Chhattisgarh are the largest cement-limestone producing states, and each notifies its own rate periodically. Second, the District Mineral Foundation (DMF) contribution, mandated by Section 9B of the MMDR Act 1957 as amended by the MMDR (Amendment) Act 2015, is calculated as a percentage of the royalty payable — 30 per cent of royalty for mining leases granted through auction after 12-January-2015 (the effective date of Section 9B), and 10 per cent of royalty for leases granted before 12-January-2015 (Section 9B(6)). The DMF collections are pooled into a district-level trust and disbursed per the Pradhan Mantri Khanij Kshetra Kalyan Yojana (PMKKKY) guidelines. Third, the National Mineral Exploration Trust (NMET) contribution, mandated by Section 9C of the MMDR Act 1957 (also introduced by the 2015 amendment), is calculated at 2 per cent of royalty payable and is pooled at the national level to fund regional mineral exploration by the Geological Survey of India, Mineral Exploration Corporation Limited and the state directorates of geology and mining. For every listed cement manufacturer — UltraTech Cement, Ambuja Cements (Adani group), ACC Limited (Adani group), Dalmia Bharat, Shree Cement, JK Cement, Ramco Cements, Nuvoco Vistas, Birla Corporation, JSW Cement, Prism Johnson, HeidelbergCement India, India Cements, Star Cement — all three levies are audited by CARO 2020 (statutory dues), disclosed in the notes to financial statements as statutory levies on mineral extraction, and captured in the plant's monthly cost of production working under Ind AS 2 Inventories. The three levies together — royalty + DMF + NMET — commonly move the effective per-tonne extraction cost by 30-45 per cent over the base royalty figure, which is why the calculator surfaces each line separately.

Section 9B of the MMDR Act 1957 was inserted by the MMDR (Amendment) Act 2015 (effective 12-January-2015) to establish the District Mineral Foundation as a trust for the benefit of persons and areas affected by mining-related operations. Sub-section 6 fixes the contribution rate at not exceeding one-third of the royalty for auction-route leases granted after the appointed date, and not exceeding one-third of the royalty for pre-existing leases. The rules made under Section 9B (the Mines and Minerals (Contribution to District Mineral Foundation) Rules 2015) subsequently notified the operative rates as 30 per cent of royalty for auction-route leases granted after 12-January-2015 and 10 per cent of royalty for leases granted before 12-January-2015 that were continued under transitional provisions. This vintage split matters materially to the cement industry because most legacy captive limestone leases held by UltraTech, ACC, Ambuja, Dalmia Bharat, India Cements, Ramco and other pre-2015 lessees were granted under the earlier first-come-first-served regime and attract the 10 per cent DMF rate under the transitional provision. New leases granted through auction post-12-January-2015 — increasingly the norm as legacy leases expire, are surrendered or are re-auctioned — attract the 30 per cent DMF rate. For the CFO planning a new plant or a limestone lease renewal, the DMF vintage swing from 10 per cent to 30 per cent of royalty is a step-change in the per-tonne mineral extraction cost that flows directly into the Ind AS 2 cost of production and into the plant's contribution margin. The tool separates the two vintages so the same extraction volume can be modelled at either 10 per cent or 30 per cent DMF to size the cost-per-tonne impact.

Section 194Q of the Income-tax Act 1961, inserted by the Finance Act 2021 and effective from 1-July-2021, requires any buyer whose total sales, gross receipts or turnover from business exceeds ten crore rupees during the immediately preceding financial year to deduct tax at source at the rate of 0.1 per cent of any sum being the value or aggregate value of the purchase of goods from any seller exceeding fifty lakh rupees in the previous year. Two limestone acquisition modes exist for a cement plant. First, a captive mining lease — the cement company itself holds the mining lease and extracts limestone from its own captive mine, paying the royalty (plus DMF plus NMET) directly to the state government. Section 194Q(3) explicitly excludes any sum credited or paid by a buyer to the Central Government, State Government, embassy, high commission, legation, commission, consulate or trade representation of a foreign state, or any other person notified by the Central Government from the ambit of Section 194Q. The royalty (plus DMF, which is a state-collected levy channelled through a district trust, and NMET, which is a national-level trust levy) paid on a captive mining lease is a payment to the State Government (or to trusts constituted under a Central statute for the benefit of persons and areas affected by mining) and is therefore outside Section 194Q. No 0.1 per cent TDS applies. Second, third-party limestone procurement — the cement plant does not hold the mining lease and instead procures limestone from a merchant miner (a third-party lessee, a limestone trader, a slurry supplier) on a purchase-order basis. In this mode, the aggregate purchase from any single seller PAN in the financial year is a normal Section 194Q trigger. Where aggregate purchase from a seller PAN exceeds fifty lakh rupees in the previous year, the buyer must deduct 0.1 per cent TDS on the aggregate purchase above the fifty-lakh threshold. The tool surfaces the trigger and the TDS quantum only in the third-party mode; in the captive mode the tool annotates the row with 'Section 194Q(3) exempt — payment to State Government' so the plant's reconciliation team has an audit-trail note explaining the deliberate no-TDS treatment. Section 206C(1H) tax collection at source at the seller side does not apply on royalty to the State Government (same Section 206C(1H)(a) government-payment exclusion); on third-party merchant-miner sales above Rs 50 lakh Section 206C(1H) applies at the seller side unless Section 194Q on the buyer side is already applicable — see CBDT Circular 13/2021 for the mutual-exclusion drill.

The Pradhan Mantri Khanij Kshetra Kalyan Yojana (PMKKKY), notified by the Ministry of Mines in September 2015 (revised in January 2024), operationalises the utilisation of District Mineral Foundation funds collected under Section 9B of the MMDR Act 1957. Every DMF trust — one per district that has an operational mining lease — is required to distribute the DMF funds it receives according to the PMKKKY guideline's two-basket split: (i) high-priority areas — at least 60 per cent of the DMF corpus is to be spent on drinking water supply, environment preservation and pollution control measures, health care, education, welfare of women and children, welfare of aged and disabled people, skill development and sanitation; (ii) other-priority areas — up to 40 per cent of the DMF corpus is to be spent on physical infrastructure, irrigation, energy and watershed development, and any other measures for enhancing environmental quality in mining districts. The 60/40 split is enforced by the district DMF trust's governing council (chaired by the District Collector/District Magistrate, with elected representatives from affected panchayats and a cement industry representative in a mining-dominant district) and audited by the state directorate of mines. For the cement plant's CSR and community-relations team, the PMKKKY 60/40 distribution is the operational lens through which the plant's DMF contribution reaches the mining-affected community — it is not a discretionary corporate CSR spend under Companies Act 2013 Section 135 (that runs separately at 2 per cent of net profit), but a statutorily-directed levy channelled through the district trust. The tool surfaces the 60/40 split so the plant's CFO and CSR head have a common per-year figure to plan against the community-relations calendar (health camps, school infrastructure grants, watershed programmes, panchayat road connectivity) that reflects where the plant's DMF rupees are being deployed.

Ind AS 2 Inventories requires cost of inventories to comprise all costs of purchase, costs of conversion and other costs incurred in bringing the inventories to their present location and condition. For a cement plant with captive limestone extraction, the per-tonne cost of limestone at the crusher includes: (i) the direct extraction cost per tonne — mine operator wages, drilling and blasting consumables, haul-road diesel, plant maintenance allocated on a per-tonne basis — captured in the mine cost centre; (ii) the statutory mineral levies per tonne — royalty per tonne plus DMF per tonne (30 per cent or 10 per cent of royalty) plus NMET per tonne (2 per cent of royalty); (iii) the amortised upfront lease premium per tonne — the reserve rupees paid at the time of the lease auction or grant, amortised over the mine life either on a units-of-production basis (Rs premium divided by total recoverable tonnes over mine life) or on a straight-line basis over the lease term (whichever the plant's accounting policy prescribes under Ind AS 16 and Ind AS 38 for mineral rights). The tool computes the units-of-production amortisation by default — annual extraction MTPA times mine life (years) equals total recoverable tonnes, and Rs upfront lease premium divided by total recoverable tonnes equals the per-tonne amortised lease premium included in the Ind AS 2 cost of limestone at the crusher. Adding the direct extraction cost, the statutory mineral levies and the amortised lease premium gives the fully-loaded per-tonne cost of limestone that flows into the raw meal blend at the raw mill, and thence into the per-tonne cost of clinker at the kiln and per-tonne cost of cement at the finish mill. The reconciliation team's monthly close must tie the tonnage extracted (weighbridge log + haul-truck ticket log), the royalty computed at the notified per-tonne rate for the state, the DMF at 30 per cent or 10 per cent of royalty per the lease-vintage flag, the NMET at 2 per cent of royalty, and the amortised lease premium for the month against the mine plant's cost sheet and against the plant's SAP FI or Oracle EBS or Tally ERP monthly journal. Any misclassification or missed line item surfaces in the CARO 2020 statutory dues walk-through or in the tax audit Form 3CD Clause 27(a) statutory dues reconciliation.
