Effective April 15, 2026, Indonesia’s ESDM will implement a revised Nickel Ore HPM formula. The Correction Factor (CF) for 1.6% grade ore rises to 30%, decreasing by 1% for every 0.1% drop in nickel grade. Byproducts are now explicitly valued: Cobalt and Iron carry a 30% CF, while Chromium is 10%. Crucially, cobalt will only be factored into the pricing if its content is >= 0.05%, and iron content must be <= 35% to be included in the calculation.
HPM Nickel Ore = 【(HMA Nickel * %Ni * CF Nickel Ore) + (HMA Cobalt * %Co * CF Cobalt ) + (HMA Iron Ore * %Fe *CF Iron * 100) + (HMA Chrome Ore * %Cr * CF Chrome * 100)】*(1-MC)
