Coal specification |

Coal specification

SUEK AG mainly exports coal containing high volatile matter above 30% on dry basis (except for the Apsat coal). Although there are several standard specifications for each delivery direction, we are able to deliver specific blends in order to meet coal parameters our customer may require.

There are 4 main specifications of coal for this direction. The first is standard Kuzbass blend having quality parameters common for the Kuzbass coal of high volatile. The second is High AFT Kuzbass blend which consists of slightly lower ash and AFT higher than the usual Kuzbass coal.

The third specification is – Low CV type. Low CV type is mainly delivered by rail and sea to the countries of Eastern Europe. The last type of coal is high volatile PCI coal delivered to metallurgical companies based in Atlantic region.

Sized coal for house heating is produced predominantly by SUEK units in Khakassia. In last years export of sized coal from Kuzbass entities is developing. We sells several grades of sized coal, both washed and unwashed.
