Coal Blending Approval Gets 14-Day Timeline: Mining Companies Gain Greater Certainty for Operational Planning

The Minister of Energy and Mineral Resources (“Minister”) has issued Decree No. 323.K/MB.01/MEM.B/2026 on Guidelines for the Implementation of Applications, Evaluations, and Approvals for Coal Blending in Mineral and Coal Mining Business Activities (“Decree 323/2026”).

Companies are now required to prepare coal-blending simulation data, an approved Work Plan and Budget (Rencana Kerja dan Anggaran Biaya – “RKAB”), and quality testing certificates issued by registered surveyors to avoid application rejection by the system.[1] In addition, this Decree directly links the sale of blended coal to the obligation to calculate and pay non-tax state revenue.[2]
