The DGFT, however, said that the sulphur content in the NPC should be less than 0.8 per cent, which would be monitored by state pollution control boards. It also said that the import of low-sulphur pet coke is restricted, and its imports are subject to authorisation from the directorate for use in integrated steel plants only for blending with the coking coal in recovery-type coke ovens equipped with desulphurisation plants.
