As of June 2026, global primary nickel supply is dominated by Indonesia and the Philippines on the mining side and by Chinese HPAL and NPI converters on the intermediate side, with LME three-month nickel oscillating in a US$15,000-17,000/t band through Q1-Q2 2026 [S1].
This matters to process engineers, battery cell buyers, and stainless procurement because the same metal now flows through two chemically distinct chains: the matte/sulphate path for Class 1 battery feedstock and the NPI/ferronickel path for austenitic stainless and nickel alloy feedstock, with very different specifications, contract forms, and risk profiles [S3].
Where the tonnes come from: mine and intermediate map
Indonesia accounts for the largest share of mined and intermediate nickel output in 2026, followed by the Philippines for ore and China for refined Class 1 and battery-grade nickel sulphate [S3].
Two conversion technologies carry the incremental tonnes: rotary kiln electric furnace (RKEF) NPI for stainless, and high-pressure acid leaching (HPAL) mixed hydroxide precipitate (MHP) that feeds nickel sulphate for precursor and active cathode plants [S3]. HPAL projects commissioned in Indonesia and China in 2023-2025 have shifted the marginal Class 1 supplier from Russia and Canada to Indonesia-China joint ventures by 2026 [S3].
Price bands and contract forms process buyers actually see
LME three-month nickel traded in a US$15,000-17,000/t range through the first half of 2026, with MHP payables quoted against the LME and battery-grade NiSO4 contracts increasingly priced on a tonne-of-nickel-in-sulphate basis rather than per-pound-of-Ni [S1].
Stainless buyers still see the traditional ferronickel and NPI contracts priced per percentage of nickel contained, while battery-grade NiSO4 is quoted per tonne of Ni metal equivalent with Co and Na impurity penalties, meaning the same headline LME move translates to different landed cost changes across stainless versus cell supply chains [S1][S3].
Stainless versus battery: two chains, two spec gates
The stainless chain wants Fe-Ni-Cr alloys with nickel content typically 8-12% in 304/304L and 8-10% in 316/316L, so ferronickel and NPI at 8-38% Ni are blended in the EAF/AOD step against prime scrap [S3].
The battery chain wants NiSO4·6H2O at ≥22% Ni basis with Co ≤0.5%, Cu ≤10 ppm and Fe ≤10 ppm, fed into precursor pCAM then NCM811 or NCM523 cathode; impurities drive cell cycle life, which is why the chain pays a Class 1 purity premium over NPI even when LME nickel is flat [S3]. For buyers of nickel alloy such as Inconel 625, 718, Monel 400 and Hastelloy C-276, the relevant spec gate is ASTM B446 / B637 / B164 / B574 chemistry with controlled Co, S, P, and N, and a separate scrap-to-master-melt route from vacuum induction melting.
Concentrate, MHP and matte: spec by spec
Laterite nickel ore is sold on a 1.5-2.0% Ni cut-off for saprolite and 1.0-1.5% Ni for limonite, with Fe, MgO, SiO2 and moisture penalties driving the realised price [S1].
MHP typically assays 35-45% Ni with 2-5% Co, 0.1-0.5% Mn and minor Cu/Zn; the dissolving customer in China re-leaches MHP to NiSO4, so Fe, Al, Ca and Mg lixiviation behaviour determines whether the MHP goes into rotary or autoclave dissolution [S3]. Nickel matte at 65-75% Ni with low Fe is the high-purity feed for direct sulphate plants and is contracted on a Co-credit basis, which matters when the cobalt-to-nickel ratio on the LME diverges from the MHP payables ratio [S1][S3].
Logistics, lead times and where supply chain software earns its seat
Indonesian ore and MHP move by Capesize and Panamax from Sulawesi and Halmahera to Chinese converters; typical voyage time is 7-12 days, with port congestion at Morowali and Weda Bay adding 3-10 days in peak months [S1].
European and North American buyers of Class 1 briquettes and pellets see 30-45 day lead times plus 25-35 day sea transit, meaning a Q2 2026 booking lands in Q3 2026; risk-management platforms ranking in the 2026 supply chain software comparisons focus on multi-tier supplier visibility, what-if disruption modelling, and inventory-plus-rail dashboards rather than simple order tracking [S1][S4]. Related cobalt chain bottlenecks hit nickel converters first because Co and Ni travel together in MHP and matte, which is why buyers tracking Cobalt Upstream and Downstream 2026: Mine to Cell Supply Chain Map end up reading the same Indonesian and Chinese flow maps.
Who is this market for, and who it is not
Stainless mills, NCM cathode plants, plating shops and nickel alloy forge shops are the natural buyers of the 2026 nickel supply chain; the chain is NOT a fit for buyers needing Cobalt-60 or rare-earth feedstock, despite the co-production from MHP [S3].
Failure modes and constraints process engineers should plan for
The 2026 nickel chain has three recurring failure modes: HPAL autoclave downtime in Indonesia that can remove 1,000-3,000 t Ni/month for 6-12 weeks, NPI-to-class-1 conversion ramp risk where Fe and S bleed through into the sulphate plant, and ESG-driven shipment rejections into Europe under due-diligence rules for high-carbon-intensity NPI [S1][S3].
A fourth constraint is the interdependence with cobalt, since MHP and matte typically carry a Co:Nickel ratio of 1:8 to 1:15; a buyer locking in MHP payables is implicitly taking a Co hedge and should align that with their precursor Co requirement, not their cathode Co specification in isolation, or they end up mismatched on tonnage and cost [S1][S3].
Sourcing gates, standards and verification
For Class 1 nickel, the recognised spec documents are ASTM B39 (cathode), ASTM B39 + LME Grade for briquettes, and ISO 6283 for refined nickel analysis; for MHP, contracts typically cite the producer's assay plus an umpire lab clause at a LME-recognised facility, with Co, Cu, Fe, Zn, Mg and moisture on the certified analysis [S1].
For ferronickel, the standard reference is ISO 6501, with Ni content 18-38% Fe-Ni grades and phosphorus/sulfur limits; for nickel alloy stock, the spec gates shift to ASTM B446 (Inconel 625), B637 (Inconel 718), B164 (Monel 400) and B574 (Hastelloy C-276) for chemistry and mechanicals, with NACE MR0175 limits if the application is sour-service oil and gas. Buyers sourcing from Indonesia should request an IGO and ESG due-diligence pack aligned with the EU Battery Regulation and CBAM, not just the LME warrant, because the LME-recognised brand list does not yet cover ESG claims [S1].
Track the next two nodes: the Q3 2026 HPAL ramp at the new Indonesian Chinese-JV lines, and any EU CBAM adjustment on NPI carbon intensity defaults, both of which will reset the relative cost of Class 1 briquettes versus MHP-based sulphate in 2H 2026.
