The Indonesian nickel sulfate market valued USD 350.0 million in 2025, and it is anticipated to expand at a CAGR of 8.5% during 2026–2032, reaching approximately USD 618.4 million by 2032.
The Indonesia nickel sulphate market is mainly driven by rapid growth in EV battery manufacturing, abundant domestic nickel reserves, strong government support for downstream processing, and rising global demand for lithium-ion batteries. This growth is supported by Indonesia's position as the world's largest nickel producer, accounting for over 56% of global mined nickel output in 2024. Aggressive downstream processing capacity expansion through high-pressure acid leaching (HPAL) facilities, which convert laterite ore into battery-grade nickel sulfate, also drive the market. Government policies mandating domestic processing following the 2020 ore export ban catalyzed foreign direct investment exceeding USD 30 billion in integrated nickel refining and battery materials production infrastructure across the Sulawesi and Maluku regions.
Indonesia's nickel sulfate production has accelerated since 2023 when commercial-scale HPAL plants commenced operations on Obi Island and in South Halmahera. They produce mixed hydroxide precipitate (MHP), which is subsequently refined into battery-grade nickel sulfate for EV batteries. The International Nickel Study Group (INSG) reports that Indonesia produced 1.750 million tonnes of nickel in 2025, representing 46.9% of global primary nickel production.
The country's vertically integrated supply chain—from laterite mining through HPAL processing to nickel sulfate refinement—supplies cathode material producers, particularly in China, where battery manufacturing capacity continues expanding rapidly. PT Halmahera Persada Lygend operates facilities with annual nickel sulfate capacity exceeding 240,000 tonnes. While, PT Vale Indonesia and Harita Nickel groups have committed to multi-billion dollar HPAL expansions, targeting battery-grade nickel markets through 2027.
Indonesia's nickel sulfate market is being fundamentally transformed by the widespread deployment of HPAL technology for battery-grade nickel sulfate production from previously unsuitable limonite ore deposits. HPAL plants use elevated temperatures (255 degrees Celsius) and pressure (725 psi), combined with sulfuric acid, to extract nickel and cobalt from low-grade laterite ore. This produces MHP as an intermediate product, which undergoes further refining into battery-grade nickel sulfate. Harita Nickel's PT Halmahera Persada Lygend HPAL facility became operational in 2021, and it produced MHP initially and expanded to commercial nickel sulfate production in 2023. By mid-2025, Indonesia had four operational HPAL facilities, three under construction, and two in feasibility phases, located primarily in Morowali (Central Sulawesi) and Obi Island (North Maluku).
This directly responds to the rising demand for high-purity nickel sulfate (99.8%+ nickel content) for nickel–manganese–cobalt (NMC) and nickel–cobalt–aluminum (NCA) EV batteries. HPAL facilities unlock Indonesia's vast limonite reserves, estimated at approximately 60% of total nickel deposits for battery applications, previously inaccessible through conventional ferronickel smelting. Merdeka Battery Materials secured a USD 1.4-billion loan in February 2025 to construct a 90,000-tonne-per-annum-MHP-capacity HPAL plant in Indonesia Morowali Industrial Park. Moreover, Harita Nickel's integrated rotary kiln electric furnace (RKEF) and HPAL facilities on Obi Island currently process 27 million tonnes annually of saprolite and limonite ore.
The Indonesian government enforced nickel ore export ban in 2020, originally legislated in 2009's Law No. 4 on Mineral and Coal Mining. This accelerates domestic nickel sulfate processing capacity by mandating that all mined nickel ore is processed within Indonesia before export. This policy compels mining companies to either build their own downstream processing facilities or sell ore to domestic smelters, fundamentally restructuring the industry from raw material extraction toward value-added processing. Presidential Regulation No. 55/2019 designated EV industry development as a national priority, while Indonesia's National Industry Development Master Plan (RIPIN) 2015–2035 explicitly targets nickel sulfate production expansion to support battery manufacturing value chains.
These coordinated policies attracted approximately USD 30 billion in foreign direct investment into Indonesia's nickel processing infrastructure between 2018 and 2025. The funding predominantly came from Chinese companies establishing integrated mining-to-battery materials operations and South Korean firms building battery cell production facilities, including LG Energy Solution and SK On.
Hyundai Motor Group and LG Energy Solution committed USD 9.8 billion in an EV battery cell manufacturing plant with 10-GWh annual capacity. Inaugurated in 2024, it utilizes NCMA battery cells containing 90% nickel in cathodes sourced from Indonesian nickel sulfate. Sino–Indonesian joint ventures dominate midstream processing, with Indonesia Morowali Industrial Park hosting 48 nickel processing facilities, representing 30% of national capacity. They produce MHP intermediates and increasingly expanding into precursor cathode active material production to avoid potential export taxes on nickel products containing less than 70% nickel content.
Vale Indonesia announced plans in July 2025 to raise USD 1–1.2 billion in financing during 2026–2027 specifically for developing new nickel mines and HPAL smelters aimed at supplying battery-grade nickel sulfate. State-owned Indonesia Battery Corporation coordinates domestic battery industry development to create vertically integrated supply chains linking nickel sulfate producers with cathode manufacturers and battery assemblers.
Rising adoption of high-nickel cathode chemistries creates sustained opportunities for Indonesian nickel sulfate producers capable of meeting stringent purity specifications required for lithium-ion battery production. Global nickel consumption for EV batteries reached 384,000 tonnes in 2024 (11.5% of total primary nickel consumption), and it is projected to increase to 543,000 tonnes in 2025 (15.2% share). Battery-grade nickel sulfate consumption specifically was forecast to reach 265 kilotonnes by 2025 from 162 kilotonnes in 2019. This would represent a 28% compound annual growth, driven predominantly by Chinese battery manufacturing expansion.
Indonesia being the world's largest nickel producer with 21 million tonnes of reserves (approximately 24% of global reserves) positions domestic processors to capture disproportionate market share in this premium battery-grade segment. The United States and European Union are diversifying their supply chains through the Inflation Reduction Act and Critical Raw Materials Act, which incentivize sourcing from nations with ESG credentials.
Indonesian nickel sulfate producers benefit from vertically integrated supply chains providing cost advantages compared to international competitors who must source nickel intermediates separately. Harita Nickel's operations integrate mining, HPAL processing, and nickel sulfate refining on Obi Island. While, Vale Indonesia combines established infrastructure, including 365 MW of hydroelectric power generation, with expanding HPAL capacity to produce lower-carbon-intensity nickel sulfate for battery manufacturers.
Plating grade commanded the largest market share in 2025, of 55%, driven by its extensive usage in electroplating across the automotive, hardware, electronics, and decorative finishing industries. In electrodeposition processes, this grade provides readily available nickel ions at a lower cost than specialty alternatives. while maintaining sufficient purity for functional and decorative plating.

Here, sulfate nickel delivers bright finish characteristics preferred for decorative applications. The grade's cost-effectiveness compared to sulfamate alternatives makes it economically attractive for applications requiring moderate thickness coatings and corrosion protection without demanding ultra-low stress deposits or specialized performance characteristics.
The high-purity grade is projected to register the fastest growth during 2026–2032, at 8.7% CAGR, propelled by the booming requirement for Class I nickel for lithium-ion cathodes. The International Energy Agency's Global EV Outlook 2025 reports that electric car sales touched 17 million units in 2025. Battery manufacturers increasingly adopting NMC chemistries, containing 60–90% nickel content in cathodes, to achieve superior energy density and extended driving range. High-purity nickel sulfate hexahydrate (NiSO4·6H2O) is a critical precursor for cathode active material (CAM) production.
Stringent specifications regarding impurity levels (maximum 100 parts per billion magnetic materials) and crystalline purity enable consistent battery performance. Indonesia's rapid expansion of HPAL facilities producing battery-grade nickel sulfate directly addresses this demand. Automotive OEMs are shifting toward NMC 811 cathodes (80% nickel, 10% manganese, 10% cobalt) to reduce dependence on expensive cobalt, while maintaining battery capacity and safety performance.

These provinces are covered:
The Indonesian nickel sulfate market demonstrates moderate concentration with integrated vertically-structured operations spanning from nickel mining through HPAL processing to battery-grade nickel sulfate refining, differentiating it from fragmented upstream nickel mining while maintaining higher concentration than typical chemical processing industries. Market structure reflects the USD 1–3 billion in investments required per HPAL facility and government policies mandating domestic ore processing, which favor established players securing foreign partnerships and navigating complex regulations.
Concentration intensified following successful commercial-scale HPAL deployment beginning in 2021, as technological barriers prevented widespread replication until proven operational models emerged. Harita Nickel's breakthrough HPAL success on Obi Island established the technical template subsequently adopted by other Indonesian and foreign investors, creating first-mover advantages for early entrants into battery-grade nickel sulfate production.
Competitive dynamics increasingly emphasize vertical integration depth and carbon intensity differentiation as battery manufacturers scrutinize supply chain environmental credentials under pressure from Western regulatory frameworks. Companies possessing integrated operations from ore mining through cathode precursor production capture higher value-added margins compared to pure MHP intermediate producers reliant on external refining partnerships. Geographic concentration in Morowali Industrial Park and North Maluku's Obi Island/Halmahera areas creates infrastructure clustering and supply chain vulnerability. This becomes clear when production disruptions at single facilities affect regional output.
