Independent analysis
Low-sulphur thermal coal: SGS analysis
Buyers of steam coal want to see real numbers before they talk about price. This is the analysis of a coal sample issued on 31 March 2026 by SGS, acting as independent inspection agency at the load port in Tanzania. It shows a high-energy bituminous coal with low sulphur, low moisture and very low chlorine.
Ask us about availability of this quality, along with the shipment size and delivery terms you need.

Source: SGS certificate of submitted sample and analysis, issued 31 March 2026 as independent inspection agency at the load port. Analysis to ISO and other international standards. As the certificate states, the findings relate only to the submitted sample and are not a warranty that it represents all the goods. Each cargo is inspected at loading.
What it means
What this coal analysis tells a buyer
Read with your boiler and emission limits in mind. For a step-by-step method, see how to assess coal quality.
High energy, low moisture
6,573 kcal/kg GAR with only 2.9% total moisture, so you ship and burn very little water.
Low sulphur
0.34% total sulphur as received, about 0.12 kg of sulphur per GJ of heat, which helps plants meet SO2 limits.
Very low chlorine
0.005% chlorine, which reduces the risk of boiler corrosion and fouling.
Ash to plan for
15.2% ash as received. Check your ash handling, and ask for an ash fusion test: it is not part of this certificate.
Harder to grind
An HGI of 51 means the coal is relatively hard to grind. Confirm it suits your mills.
Volatile matter
31.1% on a dry ash-free basis, with 8,030 kcal/kg: the profile of a bituminous steam coal, not an anthracite.
