Indonesia Nickel Mining Quota Approval Raises Ore Supply Uncertainty

ESDM

Indonesia nickel mining quota approvals for 2026 have reached only 190mn-200mn t so far, leaving the market below the government’s earlier signalled target of 260mn-270mn t. The slower approval process has increased uncertainty over nickel ore availability and future smelter operating rates.

The approved volume remains far below the 379mn t quota granted for 2025. Indonesia had already been expected to cut this year’s RKAB quota by about one-third, but the current approved level is still tighter than many market participants expected.

Indonesia nickel mining quota uncertainty matters because the country remains the world’s dominant nickel supply hub. Any shortage of approved mining volumes could raise ore prices, reduce feedstock availability and pressure nickel pig iron, ferronickel and HPAL operations.

RKAB Delays Could Tighten Nickel Ore Availability

The RKAB approval process is moving more slowly than expected, creating operational uncertainty for miners and smelters. Companies without confirmed 2026 RKAB approvals must halt mining after the 31 March cut-off, unless new approvals are granted.

The ESDM previously allowed nickel firms to continue mining using up to 25% of their 2026 production plan until 31 March. That temporary mechanism helped avoid an immediate supply shock, but the expiration of the allowance now increases pressure on companies still waiting for approval.

Several mining firms plan to submit fresh applications for higher quotas, with reviews expected in July. This means Indonesia nickel mining quota volumes could still rise later in the year, but near-term ore availability remains exposed to administrative timing.

Sulphur and Fuel Risks Add Pressure to HPAL Operations

Indonesia’s nickel industry also faces external supply risks from fuel oil and sulphur disruptions linked to Middle East instability. The issue is especially important for HPAL plants, which rely heavily on sulphuric acid production and energy-intensive processing.

The Middle East supplies about 75% of Indonesia’s sulphur imports. If sulphur or fuel oil availability tightens, HPAL producers may face higher operating costs or even output curtailments.

Imports may offset part of the nickel ore quota shortfall, but market participants do not expect overseas material to fully meet smelter demand. Some producers may therefore face reduced operating rates if domestic quota approvals remain limited.

Indonesia is also considering tighter compliance rules. Tax compliance may become a requirement for RKAB submissions from 2027, although it remains unclear whether this will affect the 2026 process.

The Metalnomist Commentary

Indonesia nickel mining quota delays show that policy administration can become a direct supply risk in the nickel market. The bigger issue is whether Indonesia can balance resource control, smelter demand and HPAL feedstock security without creating avoidable price volatility.
