Coal Supply & International Trading

Bulk coal sourcing for industrial buyers, specified by application, quality, quantity and destination.

Duara Group coordinates coal sourcing, procurement and trading from Nairobi for domestic and international commercial requirements. Send your industrial fuel or steelmaking specification for source assessment, import/export coordination and one-off or recurring supply proposals. Commercial agreements, shipment quality and delivery capability are confirmed through quotation.

Available types and commercial grades

The options below can be investigated against a complete buyer specification. Availability, producer, origin and conformance are confirmed in the written quotation.

Coal rank

Anthracite, bituminous, sub-bituminous and lignite describe geological rank.

Commercial use

Thermal/steam coal describes heat use; metallurgical coal includes coking and PCI applications. These classifications overlap.

Process suitability

A plant-approved specification determines suitability. Every coal type does not suit every application.

Typical specification points

These are enquiry fields, not published lot values. The final specification and test basis must be agreed for each supply.

Parameter	What to define
Calorific value	State GCV or NCV, kcal/kg or MJ/kg, and analytical basis. GAR means gross as received; GAD means gross air-dried. These are not interchangeable.
Moisture	Specify total moisture as received and analysis/inherent moisture separately, with methods and limits.
Ash and sulfur	State maximum percentages and their analytical basis; add ash chemistry and fusion behaviour for the receiving process.
Volatile matter and fixed carbon	Specify basis and limits. Fixed carbon is calculated by difference in proximate analysis, not the same as elemental carbon.
Particle size	Define top and bottom screen sizes, oversize and fines tolerances, and sampling point.

Packaging and supply formats

Bulk, screened or washed material where confirmed
Shipment format assessed against order and route

Origin and sourcing options

Duara Group coordinates sourcing inquiries from Nairobi for African and international buyers. Tanzania, Kenya and South Africa are sourcing markets, subject to source verification. Supply through Kenya may be imported and does not establish Kenyan mine origin. Origin, current availability, assay, export eligibility and delivery terms are confirmed for the proposed shipment.

Documentation and certification

Lot-linked certificate of analysis with sampling date, methods and analytical bases
Independent sampling, sealed retained samples and inspection when agreed
Commercial invoice, quantity and transport documents
Certificate of origin and applicable customs or regulatory documents confirmed for the route

Buyer requirements for quotation

Intended process and approved fuel envelope
Coal type, analytical limits and acceptance/rejection criteria
Metric-ton quantity and recurring schedule
Destination country, port or final delivery location
Named Incoterm, delivery window and inspection requirements

Choose coal by rank and industrial use

Rank and application are different classification systems. Anthracite, bituminous, sub-bituminous and lignite are ranks; thermal and metallurgical describe use. Coking and PCI coal have distinct roles within metallurgical procurement.

Commercial forms, quality and bulk procurement

Lumps, fines and dust describe particle size, not rank. Specify a screen analysis and limits on undersize and oversize. Washed coal has undergone beneficiation; washing does not guarantee a particular ash content. Sized coal has been screened. Run-of-mine material is unprocessed and may require preparation. Coal briquettes are manufactured products whose binder, strength, moisture and emissions characteristics require separate approval. Charcoal briquettes and petroleum coke are different materials.

Compare offers on a common energy basis. GCV includes heat recovered by condensing combustion water; NCV excludes that latent heat. GAR and GAD use different moisture bases. One kcal/kg is approximately 0.0041868 MJ/kg. A laboratory needs moisture and, for net-value calculations, additional composition information to reconcile unlike offers accurately.

Sourcing markets and delivery coordination

Tanzania

Inquiries can assess Tanzanian origin and regional routes against the offered coal specification. The Tanzania sourcing guide explains producing regions, source checks and transport considerations. No mine access or reserved allocation is implied.

Kenya

Supply in Kenya may involve imported coal, local traders and regional deliveries. A Kenyan supplier address does not prove Kenyan geological origin. See bulk coal procurement in Kenya for delivery and source-verification questions.

South Africa

Source assessment includes grade, exporter documentation and the specific inland and port route. See the South African buyer guide. An export terminal's capacity does not establish an individual supplier's shipping allocation.

These markets do not limit international sourcing. Quote metric-ton quantities, recurring requirements and destinations. FOB, CFR or CIF proposals must identify the named port and agreed Incoterms edition. Freight scope, inspection, insurance where applicable, customs, discharge and inland delivery responsibilities belong in the contract. No minimum order, current price, capacity or lead time is guaranteed here.

Inspection, documents and acceptance

Agree representative sampling, laboratory methods, analytical bases, inspection timing, quantity measurement and retained-sample procedures before shipment. A certificate of analysis must identify the lot and sampling point. Specify remedies for off-specification material and the controlling result if load and discharge tests differ. Confirm invoice, origin and transport documents and route-specific requirements before contracting.

Buyer questions

Can I order a guaranteed grade from this page?

Submit the required limits for assessment. Origin, availability, lot analysis, price and delivery are confirmed in the written quotation; the catalogue is not a stock offer.

What should a bulk coal inquiry contain?

Include application, coal type, GCV or NCV and basis, ash, sulfur, moisture, volatile matter, fixed carbon, sizing, metric-ton quantity, destination, named Incoterm and delivery window. Add process-specific tests for coking or PCI coal.

Can supplies repeat monthly?

State monthly tonnage, receiving capacity and call-off schedule. Recurring supply needs source and logistics confirmation and agreed quality controls for each shipment.

Frequently asked questions

How is this coal qualified for my plant?

Is stock or a minimum order guaranteed?

No. Submit your metric-ton quantity and specification. Source, availability, lot analysis, order size, price and delivery terms are confirmed in a written quotation.

What does a quality certificate need to identify?

The offered lot, sampling point and date, laboratory methods, analytical bases and tested values. Agree independent inspection and retained samples where required.

Can delivery be arranged internationally?

The source, exporter eligibility, destination requirements and freight route must be verified for the transaction. State the named Incoterm, port or final delivery point and required window.
