From mine to mill, every rupee of material cost on one screen

Fuel and raw materials are the biggest controllable costs in a cement plant, and their prices swing every month. HMC gave the cement company's procurement and finance teams one view of it: where every tonne comes from, where its cost enters the process, how prices move, and what that does to cost per tonne and to the budget.

The Challenge

Volatile inputs, scattered data, late answers

Procurement buys fuel and additives for many plants from many sources. Finance has to explain cost per tonne against budget. Each team had its own spreadsheets, and the two rarely agreed on the same number at the same time.

Price swings

Petcoke and imported coal prices move with global markets and the rupee; a few dollars a tonne changes margin per bag.

Complex supply network

Fly ash, slag, gypsum, coal and petcoke reach each plant from different sources by rail, road and sea.

Landed cost in pieces

Base price, freight, handling, moisture and calorific value sat in different files, so true landed cost was hard to compare.

Variance explained late

Finance learned why cost per tonne missed budget weeks after month end, too late to act.

HMC Approach

One cost model, shared by procurement and finance

Built with both teams, so the buyer and the controller look at the same rupee.

Select a step to see what happened.

Discover · Follow the tonne

Traced every input from source to kiln.

  • Plants, sources, modes and contracts per input.
  • How procurement and finance each calculate cost per tonne.
  • Where the numbers diverged, and why.

Deliverable: Supply network inventory and cost tree.

Design · One landed-cost definition

Agreed the rules once.

  • Landed cost = price + freight + handling + levies, adjusted for moisture or calorific value.
  • Cost per tonne of cement split by process stage and input.
  • Variance bridge: price, volume, mix, freight, efficiency.

Deliverable: Cost model specification.

Build · Map, model, lab, desk

Four tools on one data model.

  • Supply network map with disruption scenarios.
  • Price volatility lab and fuel-mix optimiser.
  • Finance desk: landed cost, contracts, variance, inventory.

Deliverable: Dashboards and models.

Adopt · Into the monthly rhythm

Used in buying and close.

  • Weekly buying review on the price lab.
  • Month-end variance bridge for finance.
  • Shared assumptions across both teams.

Deliverable: Review cadence and playbook.

Scale · More inputs, more plants

The model extends.

  • Power and packing materials next.
  • New plants added as nodes, not new files.
  • Forecasts feed the annual budget.

Deliverable: Roll-out roadmap.

The Solution

Four views of the same cost

Where materials come from, where their cost enters the process, how their prices move, and how finance explains the result. All data on this page is synthetic.

01 · Supply network map

Every inbound lane, moving

Plants and their sources across India, with material flowing by rail, road and sea. Filter by input, click a plant for its supply mix, or switch on a disruption to see lanes reroute and what it costs.

Disruption scenarios

Plant locations approximate; sources, lanes, volumes and costs synthetic. Boundaries: Survey of India outline via DataMeet (CC BY).

02 · The plant in 3D

Where the cost enters the process

Follow limestone from the quarry to the dispatch bay. Drag to orbit, scroll to zoom, and click any stage to see what it consumes and what it costs per tonne of cement. Switch on the cost lens to heat-map the plant.

03 · Price volatility lab

How prices move, and what it does to a bag of cement

Three years of synthetic input prices, indexed. Brush the timeline to zoom. Then shock the inputs and watch cost per tonne, cost per bag and annual impact move, and find the cheapest kiln fuel mix the chemistry allows.

Petcoke share of kiln heat

Balance is imported coal. Above the sulphur limit, petcoke raises SO₃ in clinker beyond what the kiln can handle without bypass; the shaded zone is off-limits.

Synthetic price series and cost structure; not market data.

04 · Finance desk

Landed cost, contracts, variance and stock, in one place

The finance view of the same data: compare suppliers on true landed cost, see what contracts saved against spot, explain cost per tonne against budget, and balance stock cover against cash.

Impact Dashboard

Lower cost per tonne, explained sooner

Fuel mix, sourcing and contract levers took cost out; the shared model meant variances were understood while there was still time to act.

Key Takeaways

What any manufacturer can borrow

01

Compare landed, not quoted

The cheapest price at the source is often not the cheapest tonne at the plant gate.

02

Simulate before you buy

Knowing what a price shock does to a bag of cement turns market news into a buying decision.

03

One model for buyer and controller

When procurement and finance share the cost tree, variance stops being a debate and becomes an action list.
