Thermal coal
Compare imported and domestic coal by calorific value, moisture, ash, sulphur, sizing, and the application you have in mind.
Known for consistent quality, low ash content, and efficient combustion properties. Used across power generation, cement manufacturing, textile processing, paper industries, and other process heat applications.
Available across different calorific values and specifications based on buyer requirement.
Recognized for superior calorific value, reliable combustion characteristics, and broad industrial acceptance through Richards Bay linked grades.
Commonly requested by power, cement, sponge iron, and industrial boiler buyers.
High energy coal with low moisture levels and consistent standards from established international supply chains, including NAPP seam references.
Used in power generation, cement manufacturing, and industrial applications that require stable heat value.
A cost-effective domestic fuel option for power generation, cement, sponge iron, steel, and general industrial applications.
India has large reserves of primarily non-coking coal with coking coal available in selected regions.
High calorific value thermal coal with low ash characteristics and competitive market pricing for power, cement, steel, and industrial users.
A practical option for buyers seeking international coal supply alternatives.

Metallurgical coal
Coking coal is chosen for how it carbonizes into coke, which acts as both fuel and reducing agent in integrated steelmaking.
How each coal type contributes to a steelmaking blend.
| Coal type | Fixed carbon | VM | CSR | Blend role |
|---|---|---|---|---|
| Hard coking coal | 85%-90% | 20%-25% | >60% | Backbone of the blend; provides maximum structural strength |
| Medium coking coal | 80%-85% | 25%-32% | 50%-60% | High fluidity; helps bind other coals during heating |
| Semi-soft coking coal | 75%-80% | 32%-38% | <50% | Filler coal for cost control and blend flexibility |
| PCI coal | Variable | 10%-40% | N/A | Powder injection to reduce coke costs |
Indicative ash bands and quality notes.
| Grade | Ash specification | Quality insight |
|---|---|---|
| Steel Grade I | < 15% ash | Premium quality; often requires minimal washing |
| Steel Grade II | 15%-18% ash | Standard metallurgical quality for Indian furnaces |
| Washery Grade I | 18%-21% ash | Requires cleaning before steelmaking use |
| Washery Grade II | 21%-24% ash | Often used as a blend component |
| Washery Grade III/IV | 24%-35% ash | Used in smaller plants or power generation |

Met coke
150-200 mm / 100-150 mm
Designed for large blast furnace operations where high mechanical strength, permeability, and stable furnace support are essential.
60-80 mm
Used in medium-sized blast furnaces and foundries for balanced strength, combustion efficiency, and heat distribution.
40-60 mm
Suitable for smaller industrial furnaces and cupola operations that need uniform heat generation.
5-30 mm
Used in sinter plants, ferro alloy production, and smaller furnaces for efficient combustion and heat transfer.
