An Indian cement producer dispatching Portland cement (HSN 2523 10) and other hydraulic cements (HSN 2523 90) from an integrated plant into a multi-state market runs a monthly GST outward-supply reconciliation surface where every tonne of cement leaves under one of two tax regimes — intra-state supply attracting CGST at 14 percent plus SGST at 14 percent (aggregate 28 percent) under Section 9 of the CGST Act 2017 and Section 9 of the respective State GST Act, or inter-state supply attracting IGST at 28 percent under Section 5 of the IGST Act 2017. The GST Council 55th meeting of September 2025 retained cement at the 28 percent highest-slab rate in the GST 2.0 rate rationalisation pivot despite sustained industry lobby for a reduced slab. Warehouse-to-market transfer between plant and company-owned depot in another State is inter-state under Section 7 read with Section 25(4) even without change in beneficial ownership. Buyer-side, Section 17(5)(c) and Section 17(5)(d) block input tax credit on cement received for construction of immovable property except plant and machinery — the 28 percent GST is a sunk cost for a real-estate developer buyer and an ITC-eligible input for an infrastructure or plant-construction buyer under the explanation carve-out. The reconciliation surface must hold monthly dispatch register, intra-state versus inter-state supply split, warehouse-to-market transfer identification, Rule 138 e-way bill parallel control, GSTR-1 filing, GSTR-3B liability reconciliation, GSTR-9 and 9C annual reconciliation and the buyer-side ITC availability classification file.
Build a per-plant-per-month cement dispatch and GST reconciliation ledger. For each monthly dispatch, capture the plant weighbridge and dispatch-gate-pass record with buyer GSTIN, destination State, invoice number, invoice value, taxable value and cement tonnes. Split the dispatch pool between intra-state supply (destination State code equals plant State code) attracting CGST 14 percent plus SGST 14 percent, and inter-state supply (destination State code differs from plant State code) attracting IGST 28 percent. Identify warehouse-to-market transfer separately (plant-to-company-owned-depot dispatch across State) as inter-state under Section 7 read with Section 25(4). Compute the monthly CGST plus SGST liability on intra-state supply and the IGST liability on inter-state supply. Cross-reference every consignment above fifty thousand rupees threshold to a generated Rule 138 e-way bill in Form GST EWB-01 with vehicle number in Part B and test for distance-based validity. File GSTR-1 outward-supply return by the 11th of the following month with dispatch-register-matched aggregates and file GSTR-3B summary return by the 20th of the following month with liability reconciled to GSTR-1 and ITC claim reconciled to GSTR-2B. Maintain the buyer-side classification file — real-estate developer buyer (ITC blocked under Section 17(5)(d)), infrastructure or plant-construction buyer (ITC eligible under plant-and-machinery exception) — for downstream Departmental scrutiny. Watch the GST Council rate-change decision cycle (55th meeting September 2025 retained 28 percent — future meetings may revisit) and flag any rate-change notification for immediate ledger re-parameterisation.
Plant master with plant GSTIN, State code, dispatch-gate-pass system integration, weighbridge integration. Buyer master with GSTIN, State code, address, industry category (real-estate developer, infrastructure buyer, plant-construction buyer, government works contractor, cement dealer) driving buyer-side ITC availability classification. HSN master with 2523 10 (Portland cement grey and white) and 2523 90 (other hydraulic cements) both at 28 percent as of GST Council 55th meeting September 2025 retention. Intra-state supply computation at CGST 14 percent plus SGST 14 percent driven off destination State code equals plant State code. Inter-state supply computation at IGST 28 percent driven off destination State code differs from plant State code. Warehouse-to-market transfer identification driven off plant-to-company-owned-depot dispatch pattern with Section 7 read with Section 25(4) inter-state tag. Rule 138 e-way bill generation trigger above fifty-thousand-rupees consignment value with Form GST EWB-01 Part A and Part B (vehicle number) capture and distance-based validity computation. GSTR-1 filing by 11th of following month, GSTR-3B filing by 20th, GSTR-9 annual return and GSTR-9C reconciliation statement filing. Section 17(5)(c) and 17(5)(d) buyer-side classification file. GST Council rate-change watch trigger with immediate rate-master re-parameterisation on any Council notification amending Notification 1/2017.
A month-end plant GST outward-supply reconciliation packet: the monthly cement dispatch register with weighbridge-matched tonnage and gate-pass-matched invoice value; the intra-state supply sub-register with CGST 14 percent and SGST 14 percent computation; the inter-state supply sub-register with IGST 28 percent computation; the warehouse-to-market transfer sub-register with the Section 7 read with Section 25(4) inter-state tag; the Rule 138 e-way bill cross-reference register with generated EWB numbers and vehicle numbers in Part B; the GSTR-1 outward-supply return filed on or before the 11th; the GSTR-3B summary return filed on or before the 20th with liability reconciled to GSTR-1 and ITC claim reconciled to GSTR-2B; the buyer-side classification file supporting Section 17(5)(c) and 17(5)(d) determinations. Annually, the GSTR-9 annual return and the GSTR-9C reconciliation statement matching the year's cumulative dispatch register to the outward-supply tax paid. Every material deviation between dispatch register and GSTR-1, between GSTR-1 outward liability and GSTR-3B tax paid, between e-way bill count and consignment count above threshold, or between buyer-side classification and observed downstream usage flagged for the plant CFO, the taxation lead and the statutory auditor. Multi-year continuity of the reconciliation packet produces the audit trail that a Departmental scrutiny under Section 65 (audit) or Section 66 (special audit) of the CGST Act 2017, an annual GSTR-9C statutory audit and any downstream buyer-side ITC dispute all expect.
An Indian cement producer operating an integrated cement plant and dispatching Portland cement (HSN 2523 10) and other hydraulic cements (HSN 2523 90) into a multi-state market runs a monthly Goods and Services Tax outward-supply reconciliation surface where every tonne of cement leaves the plant gate under one of two parallel tax regimes. Intra-state supply — where the location of the supplier and the place of supply are in the same State — attracts Central GST at 14 percent under Section 9 of the CGST Act 2017 plus State GST at 14 percent under Section 9 of the respective State GST Act, aggregating to the 28 percent highest-slab rate under Schedule IV of Notification 1/2017-Central Tax (Rate). Inter-state supply — where the location of the supplier and the place of supply are in two different States, two different Union Territories or a State and a Union Territory — attracts Integrated GST at 28 percent under Section 5 of the IGST Act 2017. The rate does not vary by intra-state versus inter-state character; only the split between CGST plus SGST and IGST varies. The GST Council 55th meeting of September 2025 retained cement at the 28 percent highest-slab rate in the GST 2.0 rate rationalisation pivot despite sustained industry lobby through the Cement Manufacturers Association for movement to a reduced slab. The reconciliation discipline that ties the plant’s monthly dispatch register to the GSTR-1 outward-supply return, splits the supply pool between intra-state and inter-state legs, identifies warehouse-to-market transfer as inter-state under Section 7 read with Section 25(4), tests the Section 17(5)(c) and Section 17(5)(d) buyer-side input tax credit block that applies to cement received for construction of immovable property except plant and machinery, and holds the parallel Rule 138 e-way bill as the goods-in-transit control for every consignment is the subject of this cement HSN 2523 GST 28 percent inter-state IGST vs CGST SGST walkthrough.
The reconciliation in one paragraph
An Indian cement producer must capture every tonne of cement leaving the plant gate against a monthly GSTR-1 outward-supply reconciliation surface that splits the dispatch pool between intra-state supply (CGST 14 percent plus SGST 14 percent) and inter-state supply (IGST 28 percent) — with warehouse-to-market transfer between the plant and a company-owned depot in another State classified as inter-state under Section 7 of the IGST Act 2017 read with Section 25(4) of the CGST Act 2017 even without change in beneficial ownership. The core reconciliation surface is a per-plant-per-month dispatch ledger keyed on the plant GSTIN, holding weighbridge-matched tonnage from every dispatch, buyer GSTIN and destination State from every invoice, taxable value and cement tonnes per line, the intra-state versus inter-state split driven off destination State code versus plant State code, the CGST and SGST computation for the intra-state pool at 14 percent each, the IGST computation for the inter-state pool at 28 percent, the Rule 138 e-way bill cross-reference for every consignment above the fifty-thousand-rupees threshold, the GSTR-1 filing by the 11th of the following month, the GSTR-3B summary filing by the 20th with liability reconciled to GSTR-1 and input tax credit claim reconciled to GSTR-2B, and the buyer-side Section 17(5)(c) and 17(5)(d) classification file for downstream Departmental scrutiny. Every material deviation between dispatch register and GSTR-1, between GSTR-1 outward liability and GSTR-3B tax paid, between e-way bill count and consignment count above threshold, or between buyer-side classification and observed downstream usage is flagged as a month-end break for the plant CFO and the taxation lead.
What the scenario looks like in India — a Neemuch MP integrated plant persona
The illustrative persona for this walkthrough is a Tier-1 Indian cement producer operating an integrated cement plant of 4.5 million tonnes per annum (MTPA) cement capacity in Neemuch, Madhya Pradesh, dispatching finished cement into a North and Central India market footprint. The plant is registered under the Central Goods and Services Tax Act 2017 with a Madhya Pradesh GSTIN and dispatches monthly across five destination-State buckets — 42 percent to intra-state Madhya Pradesh buyers, 18 percent to Rajasthan, 14 percent to Delhi National Capital Territory, 12 percent to Uttar Pradesh and 14 percent to other North India States (Punjab, Haryana, Himachal Pradesh, Uttarakhand). The Madhya Pradesh leg is intra-state and attracts CGST 14 percent plus SGST 14 percent; the Rajasthan, Delhi, Uttar Pradesh and other-North-India legs are inter-state and attract IGST at 28 percent.
Illustrative Tier-1 and Tier-2 Indian cement producers operating integrated cement plants of comparable capacity in Madhya Pradesh (Neemuch, Satna, Rewa, Katni), Rajasthan (Sirohi, Chittorgarh, Nimbahera), Karnataka (Kalaburagi, Wadi), Andhra Pradesh and Telangana (Kadapa, Nalgonda), Gujarat (Kutch), Tamil Nadu (Ariyalur, Salem), Chhattisgarh and Odisha (Baloda Bazar, Rajgangpur) and the North-East (Lumshnong), running the same GSTR-1 outward-supply reconciliation stack under Notification 1/2017 Schedule IV at the 28 percent cement rate, include UltraTech Cement (Aditya Birla), Shree Cement, Ambuja Cements (Adani), ACC Ltd (Adani), Dalmia Bharat Cement, JK Cement, Ramco Cements, Birla Corporation, HeidelbergCement India, JK Lakshmi Cement, Prism Johnson, Nuvoco Vistas, Star Cement, Orient Cement, India Cements, Sanghi Cement and Sagar Cements. Every one of these producers dispatches from at least one integrated plant into a multi-state market and runs the intra-state-versus-inter-state split reconciliation monthly against the GSTR-1 filing.
The regulatory overlay — Notification 1/2017 Schedule IV, IGST Act Section 5, Section 17(5)(c), Rule 138
Four regulatory anchors govern a cement plant’s outward-supply GST reconciliation. Section 9 of the CGST Act 2017 read with Section 9 of the respective State GST Act levies CGST plus SGST on intra-state supply. Section 5 of the IGST Act 2017 levies IGST on inter-state supply as defined in Section 7. Section 17(5)(c) and Section 17(5)(d) of the CGST Act 2017 govern the buyer-side blocked-credit position on cement received for construction of immovable property. Rule 138 of the CGST Rules 2017 mandates the e-way bill for every consignment above the fifty-thousand-rupees threshold.
Notification 1/2017-Central Tax (Rate) dated 28 June 2017 as amended prescribes the GST rate schedule for goods. Schedule IV lists goods attracting the 28 percent slab, including HSN 2523 covering cement (whether or not coloured, in the form of clinker). Sub-heading HSN 2523 10 covers Portland cement (grey and white) — Ordinary Portland Cement (OPC 33, 43, 53 grades) under IS 269:2015, Portland Pozzolana Cement (PPC) under IS 1489, Portland Slag Cement (PSC) under IS 455 and Portland Composite Cement. Sub-heading HSN 2523 90 covers other hydraulic cements including sulphate-resistant cement, low-heat cement, oil-well cement and rapid-hardening cement. The parallel Notification 1/2017-State Tax (Rate) issued by each State prescribes SGST at 14 percent on the same HSN 2523; Notification 1/2017-Integrated Tax (Rate) prescribes IGST at 28 percent.
The GST Council 55th meeting held in September 2025 undertook the GST 2.0 rate rationalisation pivot with a headline direction to compress the multi-slab structure. The Cement Manufacturers Association lobbied for movement of HSN 2523 from the 28 percent slab to a reduced 18 percent slab, citing the housing-and-infrastructure downstream demand elasticity and the tax-on-tax cascade for real-estate buyers under the Section 17(5)(d) ITC block. The Council, after considering the revenue implication and the mature-industry-with-high-value-addition classification, retained cement at the 28 percent slab. Cement producers plan their FY 2026-27 GST outward-supply position on the 28 percent basis with no rate-reduction relief in the near-term horizon.
Section 7 of the IGST Act 2017 defines inter-state supply — the location of the supplier and the place of supply in two different States, two different Union Territories or a State and a Union Territory. Section 25(4) of the CGST Act 2017 provides that a person who has obtained or is required to obtain more than one registration, whether in one State or Union Territory or more than one State or Union Territory, shall in respect of each such registration be treated as distinct persons. A warehouse-to-market transfer where the Neemuch MP plant dispatches cement to a company-owned depot in Rajasthan, Delhi or Uttar Pradesh is inter-state under Section 7 read with Section 25(4) — each GSTIN of the same legal entity in a different State is a distinct person and the transfer attracts IGST at 28 percent even though beneficial ownership does not change. The clinker inter-unit stock transfer GST and IGST reconciliation Wave 1 sibling documents the identical mechanic for the clinker-side inter-unit transfer between an integrated plant and a stand-alone grinding unit.
Section 17(5)(c) blocks input tax credit on works contract services supplied for construction of an immovable property (other than plant and machinery) except where it is an input service for further supply of works contract service. Section 17(5)(d) parallel blocks ITC on goods or services received for construction of an immovable property (other than plant and machinery) on the taxable person’s own account. The explanation to Section 17 defines plant and machinery to include apparatus, equipment and machinery fixed to earth by foundation or structural support that are used for making outward supply, and includes such foundation and structural support — but excludes land, building and any other civil structures. A real-estate developer buyer of cement for construction of a residential or commercial building has ITC blocked; the 28 percent GST is a sunk cost recovered only through pricing of the unit sold. An infrastructure or industrial buyer of cement for construction of PLANT (kiln foundations, mill housings, integral equipment support structures) qualifies for the plant-and-machinery exception and is eligible for ITC on the cement 28 percent GST.
Rule 138 of the CGST Rules 2017 requires the e-way bill in Form GST EWB-01 for every consignment above fifty thousand rupees — Part A captures invoice details and Part B captures vehicle number. Distance-based validity — up to 200 kilometres, one day; each additional 200 kilometres or part thereof, one additional day. A dispatch from Neemuch MP to a destination in Delhi (approximately 700 kilometres) attracts a four-day validity window; a Neemuch-to-Bhopal intra-state dispatch (approximately 350 kilometres) attracts a two-day validity. Rule 138B provides for cancellation within 24 hours if goods are not transported or details are wrong. The parallel e-way bill Rule 138 inter-plant truck movement reconciliation Wave 2 sibling in this cluster documents the e-way bill operational cadence for the inter-plant clinker and cement movement mechanic in depth.
A worked example — Neemuch MP integrated plant FY 2026-27 monthly close
Illustrative — the following figures represent the operating pattern of a Tier-1 Indian cement producer operating an integrated cement plant of approximately 4.5 MTPA capacity in the Madhya Pradesh belt. Public disclosures by listed Indian cement majors do not reveal per-plant per-month dispatch composition and GST outflow at the granularity below; cross-verify against the current Notification 1/2017-Central Tax (Rate) rate schedule and your own dispatch register before action. The Rs 5,800 per tonne average realisation used below is an illustrative reference point and does not represent the actual realisation for any specific operating month or producer.
The Neemuch MP plant closes its FY 2026-27 monthly outward-supply position on a steady dispatch cadence of 375,000 tonnes per month (annualised 4.5 MTPA) at an illustrative average net-of-discount realisation of Rs 5,800 per tonne. The monthly dispatch split across destination-State buckets is:
| Destination bucket | Tonnes | Supply type | Rate mechanic |
|---|---|---|---|
| Madhya Pradesh (intra-state) | 158,000 (42 percent) | Intra-state | CGST 14 percent plus SGST 14 percent |
| Rajasthan (inter-state) | 67,500 (18 percent) | Inter-state | IGST 28 percent |
| Delhi (inter-state) | 52,500 (14 percent) | Inter-state | IGST 28 percent |
| Uttar Pradesh (inter-state) | 45,000 (12 percent) | Inter-state | IGST 28 percent |
| Other North India (inter-state) | 52,000 (14 percent) | Inter-state | IGST 28 percent |
| Total monthly dispatch | 375,000 |
The per-tonne GST computation at Rs 5,800 per tonne taxable value is Rs 5,800 times 28 percent = Rs 1,624 per tonne aggregate. For the intra-state supply pool, this splits into CGST at Rs 5,800 times 14 percent = Rs 812 per tonne and SGST at Rs 5,800 times 14 percent = Rs 812 per tonne. For the inter-state supply pool, the full Rs 1,624 per tonne is IGST. The monthly aggregate liability is:
| Line item | Basis | Amount (illustrative) |
|---|---|---|
| Intra-state supply pool (MP) | 158,000 tonnes | 158,000 tonnes |
| CGST at Rs 812 per tonne | 158,000 times Rs 812 | Rs 12.83 crore |
| SGST at Rs 812 per tonne | 158,000 times Rs 812 | Rs 12.83 crore |
| Intra-state pool tax subtotal | CGST plus SGST | Rs 25.66 crore |
| Inter-state supply pool | 67,500 plus 52,500 plus 45,000 plus 52,000 | 217,000 tonnes |
| IGST at Rs 1,624 per tonne | 217,000 times Rs 1,624 | Rs 35.24 crore |
| Inter-state pool tax subtotal | IGST | Rs 35.24 crore |
| Total monthly GST outward-supply outflow (before ITC) | Rs 25.66 plus Rs 35.24 crore | Rs 60.90 crore |
The GSTR-1 outward-supply return filed on or before the 11th of the following month reports the monthly aggregate — intra-state taxable value Rs 91.64 crore with CGST Rs 12.83 crore plus SGST Rs 12.83 crore, and inter-state taxable value Rs 125.86 crore with IGST Rs 35.24 crore. The GSTR-3B summary filed on or before the 20th reports the outward-supply tax liability of Rs 60.90 crore netted against the input tax credit claim reconciled to GSTR-2B (from clinker inter-unit transfer, limestone royalty-adjacent GST, coal and pet-coke GST, packaging GST, capital equipment GST) — the net cash outflow is the balance after ITC utilisation.
On the Section 17(5)(c) buyer-side dimension, the plant’s cement buyer profile splits between real-estate developer buyers (ITC blocked under Section 17(5)(d) — the 28 percent GST is a sunk cost for the developer), infrastructure buyers building plant foundations under contracts with public-sector utilities (ITC eligible under the plant-and-machinery exception) and cement dealer buyers who onward-sell to end-users (ITC available at dealer stage against the further outward supply). The buyer-side classification is a documented sub-register maintained for downstream Departmental scrutiny under Section 65 or Section 66 of the CGST Act 2017. On the Rule 138 e-way bill dimension, every consignment above the fifty-thousand-rupees threshold (essentially every full-truck-load cement dispatch given the invoice value profile) is captured against a generated EWB number with vehicle number in Part B and distance-based validity per the destination-to-Neemuch kilometres routing.
Common reconciliation breakages
Five breakages recur across Indian cement producers running the HSN 2523 28 percent outward-supply reconciliation.
-
Warehouse-to-market transfer misclassified as intra-state — inter-state IGST liability understated. The most common structural failure is misclassifying a warehouse-to-market transfer (Neemuch MP plant dispatching cement to a company-owned depot in Rajasthan, Delhi or Uttar Pradesh) as intra-state under the mistaken view that no change in beneficial ownership means no inter-state supply. Section 7 of the IGST Act 2017 read with Section 25(4) of the CGST Act 2017 is unambiguous — each GSTIN of the same legal entity in a different State is a distinct person and the transfer between plant GSTIN and depot GSTIN across State is inter-state supply attracting IGST at 28 percent. Under-declaring the inter-state pool understates the IGST liability on GSTR-1 and the GSTR-3B tax paid, triggering a short-payment position on Departmental scrutiny with Section 74 fraud-or-misrepresentation exposure (up to 100 percent penalty plus interest). Reconciliation discipline: the plant master holds the depot-GSTIN-across-State list and the dispatch-gate-pass system automatically tags every plant-to-depot-across-State dispatch as inter-state supply for the ledger split.
-
Intra-state versus inter-state split driven off destination address instead of buyer GSTIN State code. Manual dispatch clerks sometimes drive the intra-state versus inter-state classification off the truck’s destination physical address (city, State) instead of off the buyer GSTIN State code. Section 10 and Section 11 of the IGST Act 2017 read with the CGST Act define place of supply for goods primarily based on the location where movement of the goods terminates for delivery to the recipient — for a dealer registered in Rajasthan taking delivery at the dealer’s Rajasthan warehouse, the place of supply is Rajasthan and the transaction is inter-state. But for a dealer registered in Rajasthan taking delivery at a project site in MP (billed to the Rajasthan GSTIN but shipped to an MP-address site), the “billed-to versus shipped-to” mechanic under Section 10(1)(b) treats the transaction as if the buyer received the goods at the buyer’s registered location — the transaction remains inter-state. Reconciliation discipline: the ledger split is driven off buyer GSTIN State code (from the buyer master) versus plant GSTIN State code, not off the physical shipped-to address on the delivery challan, and the “bill-to-ship-to” combination is captured on a separate audit register for downstream verification.
-
Section 17(5)(c) buyer-side ITC classification not maintained — real-estate developer buyer downstream ITC dispute exposes plant reputational risk. The plant is not directly liable for the buyer’s downstream ITC dispute — a real-estate developer buyer who wrongly claims ITC on cement purchase in violation of Section 17(5)(d) faces the ITC reversal in their own GSTR-9C reconciliation and Departmental scrutiny — but the plant’s classification file becomes the referenced document trail if the Department investigates upstream. A plant that does not maintain the buyer-side classification file (real-estate developer, infrastructure, dealer) leaves itself unable to respond to a Departmental notice under Section 65 audit of a specific buyer where the plant is called upon to produce the invoice-level ITC-availability position. Reconciliation discipline: the buyer master carries an ITC-availability tag (Blocked under 17(5)(d), Eligible under plant-and-machinery exception, Eligible under dealer further-supply) driven off the industry-category classification, and the GSTR-1 outward-supply report generates the buyer-side ITC-availability aggregate as a separate sub-report retained with the monthly reconciliation packet. The Section 16(4) ITC exposure calculator is the operational lookup for the parallel time-bar mechanic on any buyer-side ITC dispute.
-
Rule 138 e-way bill missing or vehicle-number Part B mismatch — Section 129 detention exposure. A cement dispatch above the fifty-thousand-rupees threshold moving without a generated e-way bill in Form GST EWB-01 or with a stale Part B (vehicle number not updated on trans-shipment or vehicle breakdown) attracts detention under Section 129 of the CGST Act 2017 — 200 percent of tax for the owner of the goods (100 percent tax plus 100 percent penalty) or 50 percent of the value of goods reduced by tax for a person other than the owner. A Neemuch-to-Delhi dispatch of 30 tonnes at Rs 5,800 per tonne (Rs 17.4 lakh invoice value) attracts a Section 129 detention exposure of Rs 4.87 crore in the worst case if the e-way bill is missing (200 percent of Rs 17.4 lakh IGST at 28 percent = Rs 4.87 lakh tax plus Rs 4.87 lakh penalty, aggregated across all detained consignments on the same enforcement action). Reconciliation discipline: the dispatch-gate-pass system integrates with the e-way bill portal API to generate Part A automatically on invoice creation and to lock the gate-out until Part B (vehicle number) is captured; trans-shipment and vehicle-breakdown updates flow through a documented Part B update workflow with the driver mobile app or the dispatch-desk portal.
-
GST Council rate-change notification not immediately applied to the rate master — legacy 28 percent applied post-change producing over-charged tax to buyer. The 55th meeting of September 2025 retained cement at 28 percent — but the GST Council rate schedule is a living document with periodic amendments to Notification 1/2017-Central Tax (Rate). A future Council meeting that moves cement to a reduced slab (18 percent or otherwise) requires immediate re-parameterisation of the plant rate master. A rate cut applied late means the plant charges buyers at the legacy 28 percent for post-notification dispatches, over-collects the tax and faces a refund-to-buyer workflow or an unjust-enrichment issue. A rate rise (unlikely for cement but possible for other HSN) applied late means the plant under-charges buyers, absorbs the differential and faces short-payment exposure. Reconciliation discipline: a GST Council rate-change watch trigger with the taxation lead subscribing to CBIC notifications, with immediate rate-master re-parameterisation on any Council notification amending Notification 1/2017-Central Tax (Rate), and with a documented cutover date and outward-supply-invoice audit for the transition month. The reconciliation playbook for monthly close operational-cadence framework provides the standing month-end discipline for stitching the GST rate-change watch, the intra-state versus inter-state split, the e-way bill parallel control and the buyer-side classification file into the plant’s close packet.
How a reconciliation platform handles this
A purpose-built cement reconciliation platform ingests every dispatch from the plant weighbridge and gate-pass system, every buyer GSTIN and destination State from the invoice register, every warehouse-to-market transfer pattern from the plant-to-company-owned-depot dispatch flow, every e-way bill number and vehicle number from the Rule 138 portal integration, every GSTR-1 outward-supply filing and GSTR-3B summary against a per-plant-per-month reconciliation ledger keyed on the plant GSTIN. The platform tags each dispatch at capture with the applicable supply type (intra-state versus inter-state driven off destination State code versus plant State code), the warehouse-to-market inter-state tag under Section 7 read with Section 25(4), the buyer-side ITC-availability classification under Section 17(5)(c) and 17(5)(d) with the plant-and-machinery exception carve-out, and the Rule 138 e-way bill parallel control status. Standing dashboard controls surface any warehouse-to-market transfer misclassified as intra-state, any dispatch-versus-GSTR-1 aggregate mismatch, any GSTR-1-versus-GSTR-3B liability mismatch, any consignment above the fifty-thousand-rupees threshold without a generated e-way bill or with a stale Part B vehicle number, and any GST Council rate-change notification pending ledger re-parameterisation. Match-rate improvement of 51 to 88 percent on the dispatch-register-to-GSTR-1 reconciliation and on the invoice-to-e-way-bill reconciliation, combined with an ISO 27001:2022 posture and DPDP Act 2023 aligned data handling for regulator-facing submissions, is what makes the platform an infrastructure investment for a Tier-1 or Tier-2 Indian cement producer running a multi-plant multi-State dispatch footprint under the HSN 2523 28 percent outward-supply reconciliation stack — rather than a spreadsheet substitute that leaves the split, the warehouse-to-market classification, the buyer-side ITC file and the e-way bill parallel control as manual overheads on a hybrid dispatch-plus-taxation-plus-plant-finance team. The commercial pillars for this sub-cluster are cement reconciliation software India and the broader GST reconciliation software for the GSTR-1 and GSTR-3B filing-side workflow that ties into the outward-supply reconciliation surface documented here. The cement cluster hub collects the parallel Wave 1 and Wave 2 walkthroughs across the captive-limestone-lease, fuel-import, environmental-clearance, emission-monitoring, BIS-certification and waste-heat-recovery mechanics that all interlock into the plant’s monthly close packet.

- ▸ Central Goods and Services Tax Act 2017, Section 9 (levy and collection) and Section 17(5) (blocked credits) — Section 9(1) of the CGST Act 2017 levies Central GST on all intra-state supplies of goods or services or both at the rate notified by the Central Government on the recommendation of the GST Council. The parallel Section 9(1) of each State GST Act levies State GST at the same rate on the same intra-state supply. Cement classified under HSN 2523 attracts the highest slab of 28 percent under Notification 1/2017-Central Tax (Rate) as amended from time to time, split between CGST at 14 percent and SGST at 14 percent for intra-state supply. Section 17(5)(c) blocks input tax credit on works contract services supplied for construction of an immovable property (other than plant and machinery) except where such works contract service is an input service for further supply of works contract service. Section 17(5)(d) parallel blocks input tax credit on goods or services or both received by a taxable person for construction of an immovable property (other than plant and machinery) on his own account including when such goods or services or both are used in the course or furtherance of business. The plant-and-machinery exception carves out ITC eligibility on cement used in construction of PLANT (integral equipment foundations, kiln support structures, mill housings) as distinct from cement used in construction of BUILDING (office block, warehouse shell, employee housing) which remains blocked.
- ▸ Integrated Goods and Services Tax Act 2017, Section 5 (levy and collection) and Section 7 (inter-state supply) — Section 5(1) of the IGST Act 2017 levies Integrated GST on all inter-state supplies of goods or services or both at the rate notified by the Central Government on the recommendation of the GST Council. Section 7 defines inter-state supply — the location of the supplier and the place of supply are in two different States, two different Union Territories or a State and a Union Territory. For cement dispatched from an integrated plant in Madhya Pradesh to a distributor in Rajasthan, Delhi or Uttar Pradesh, the location of the supplier (Neemuch MP) and the place of supply (destination State) are in two different States and the transaction is inter-state, attracting IGST at 28 percent. For cement dispatched from the same MP plant to a distributor within Madhya Pradesh, the transaction is intra-state and attracts CGST 14 percent plus SGST 14 percent. Warehouse-to-market transfer where the plant dispatches cement from its production location to a company-owned depot in another State is also inter-state under Section 7 read with Section 25(4) (each GSTIN of the same legal entity in a different State is treated as a distinct person) and attracts IGST at 28 percent even though there is no change in beneficial ownership.
- ▸ Notification 1/2017-Central Tax (Rate) — GST rates on goods, Schedule IV cement HSN 2523 — Notification 1/2017-Central Tax (Rate) dated 28 June 2017 as amended prescribes the GST rate schedule for goods. Schedule IV lists goods attracting the 28 percent slab, including HSN 2523 covering cement, whether or not coloured, in the form of clinker. Sub-heading HSN 2523 10 covers Portland cement (grey and white) — Ordinary Portland Cement (OPC 33, 43, 53 grades), Portland Pozzolana Cement (PPC), Portland Slag Cement (PSC) and Portland Composite Cement. Sub-heading HSN 2523 90 covers other hydraulic cements including sulphate-resistant cement, low-heat cement, oil-well cement and rapid-hardening cement. The parallel Notification 1/2017-State Tax (Rate) issued by each State Government prescribes the State GST rate at 14 percent on the same HSN 2523. The parallel Notification 1/2017-Integrated Tax (Rate) prescribes the IGST rate at 28 percent on the same HSN 2523. The GST Council 55th meeting held in September 2025 considered the industry proposal to move cement from the 28 percent slab to a reduced slab under the GST 2.0 rate rationalisation pivot; the Council retained cement at 28 percent, citing revenue considerations and the mature-industry-with-high-value-addition rationale.
- ▸ CGST Rules 2017, Rule 138 (electronic way bill) and Rule 138A to 138D — Rule 138 of the CGST Rules 2017 requires every registered person who causes movement of goods of consignment value exceeding fifty thousand rupees to furnish, prior to commencement of such movement, information relating to the said goods in Part A of Form GST EWB-01 electronically on the common portal, and to generate the e-way bill by furnishing Part B (vehicle number) of Form GST EWB-01. The e-way bill is mandatory for inter-state movement above the fifty thousand rupees threshold irrespective of the State of dispatch, and for intra-state movement above the State-notified threshold (varies by State — Madhya Pradesh notifies fifty thousand rupees; some States prescribe a higher intra-state threshold). Distance-based validity — up to 200 kilometres, one day; each additional 200 kilometres or part thereof, one additional day. Rule 138B provides for cancellation of the e-way bill within 24 hours of generation if the goods are not transported or the details are wrong. Rule 138D governs detention — Section 129 of the CGST Act 2017 provides that where any person transports any goods or stores any goods while they are in transit in contravention of the provisions of the Act or the rules, all such goods and conveyance shall be liable to detention with tax at 200 percent (100 percent tax plus 100 percent penalty for the owner of the goods; 50 percent of the value of goods reduced by the tax amount for a person other than the owner).
- ▸ GST Council 55th meeting — September 2025 rate-schedule decisions and cement retention at 28 percent — The Goods and Services Tax Council under Article 279A of the Constitution of India is the apex Federal body that recommends the tax rates, exemptions, threshold limits and other matters relating to GST to the Central Government and the State Governments. The 55th meeting of the GST Council held in September 2025 undertook the GST 2.0 rate rationalisation pivot with a headline direction to compress the multi-slab structure and reduce the burden on essential consumption. The cement industry lobbied through the Cement Manufacturers Association (CMA) for movement of HSN 2523 from the 28 percent slab to a reduced 18 percent slab, citing the housing-and-infrastructure downstream demand elasticity. The Council, after considering the revenue implication and the mature-industry-with-high-value-addition classification, retained cement at the 28 percent slab in the September 2025 rate schedule. The retention decision is documented in the GST Council 55th meeting minutes published on the Council website; the rate schedule notified through amendment to Notification 1/2017-Central Tax (Rate) reflects the retention.
- ▸ CGST Act 2017, Section 17(5)(c) and Section 17(5)(d) — blocked credits with plant-and-machinery exception — Section 17(5)(c) of the CGST Act 2017 provides that notwithstanding anything contained in Section 16(1) and Section 18(1), input tax credit shall not be available in respect of works contract services when supplied for construction of an immovable property (other than plant and machinery) except where it is an input service for further supply of works contract service. Section 17(5)(d) parallel provides that input tax credit shall not be available in respect of goods or services or both received by a taxable person for construction of an immovable property (other than plant and machinery) on his own account including when such goods or services or both are used in the course or furtherance of business. The explanation to Section 17 defines plant and machinery to mean apparatus, equipment and machinery fixed to earth by foundation or structural support that are used for making outward supply of goods or services or both and includes such foundation and structural support, but excludes (i) land, building or any other civil structures, (ii) telecommunication towers and (iii) pipelines laid outside the factory premises. A real-estate developer buyer of cement for construction of a residential or commercial building has ITC blocked under Section 17(5)(d) — the 28 percent GST paid on the cement purchase is a sunk cost. An infrastructure or industrial buyer of cement for construction of PLANT (kiln foundations, mill housings, integral equipment support structures) is eligible for ITC under the plant-and-machinery exception.
