China's manganese market entered a two-speed regime in April-May 2026, with electrolytic manganese metal (EMM) softening from elevated levels while battery-grade manganese sulfate maintained firm cost support. (FACT: SMM, April 30, 2026) The divergence reflects fundamentally different demand drivers: EMM follows steel and alloy markets, where Chinese real estate weakness and global industrial slowdown have capped buying, while battery-grade sulfate benefits from structural LMFP cathode adoption that operates independently of the construction cycle.
SMM data shows EMM prices have pulled back from their 2026 highs as downstream buying softened. Mn3O4 prices weakened in sympathy, dragged by the EMM pullback and mediocre downstream LMO demand with weak restocking willingness. Electrolytic manganese dioxide (EMD) held relatively steady, with supply and demand balanced and costs stabilizing. (FACT: SMM, April 30, 2026) The manganese sulfate market tells a different story: high ore costs and elevated sulfuric acid prices (the latter driven by Russia's export restrictions) have created a rigid cost floor. (FACT: SMM, April 23, 2026) Battery-grade sulfate producers maintain strong price-firming willingness, effectively curbing downside risks despite the broader market softness.
On the raw material side, the global tight supply balance for manganese ore persists. Major overseas suppliers have raised export quotations to China, pushing up the cost of imported ore and driving domestic Chinese ore prices higher in tandem. (FACT: SMM, April 23, 2026) South32's June 2026 quotation for Australian lump ore (42% Mn) was set at $5.40/dmtu CIF China, down $0.50 from May — a modest decline that reflects steel-market weakness rather than any fundamental easing of ore supply. (FACT: Mining Bulletin, May 7, 2026)
Global manganese ore supply is projected to reach approximately 59 million tonnes in 2026, up modestly from roughly 57 million tonnes in 2025. (FACT: aInvest, April 2026) This growth is driven primarily by South Africa, where production rose 14.4% year-on-year in March 2026, and by new refining capacity in China aimed at producing battery-grade manganese sulfate for LMFP batteries. (FACT: Discovery Alert, May 18, 2026) But the alignment between new supply and the actual pace of EV adoption and LMFP penetration remains the key watchpoint. If battery demand accelerates faster than expected — particularly if LMFP exceeds 25% of Chinese EV cathode chemistry by year-end — the broadly balanced 2026 market could flip to deficit by 2028. (FACT: aInvest, April 2026)
PriceWatch data indicates the manganese ore market in South Africa remained relatively balanced through Q3 2025, with producers managing output and inventories carefully to maintain stability amid subdued steel demand. (FACT: PriceWatch, April 2026) The mild downward trend reflected softer demand from steel and ferroalloy manufacturing sectors. This pattern has continued into 2026, with EMM bearing the brunt of steel-market softness while battery-grade products decouple to the upside.
The number that matters for your business
An EMM buyer consuming 500 tonnes/month at early-2026 highs of approximately $2,300/tonne has seen prices soften roughly 5-8% through April-May. Assuming a 5% decline, the monthly saving is approximately $57,500-92,000. But this is a steel-cycle discount, not a structural one. Battery-grade manganese sulfate buyers see no such relief: the cost floor from ore and sulfuric acid has kept prices firm at approximately $800-900/tonne, and this floor is unlikely to erode as long as the global ore supply balance remains tight and Russian sulfur exports remain constrained. The two-speed market means the same commodity has two different prices depending on purity — and that gap is widening structurally.
Action: For EMM and ferroalloy buyers, the current softness from steel-market weakness may persist through mid-2026 — an opportunistic window to lock in H2 volumes if steel demand does not recover. For battery-grade manganese sulfate buyers, no such window exists: the cost floor is structural (high ore + sulfuric acid), so waiting for a price dip is unlikely to pay off. Secure H2 volumes now with the expectation that prices remain at current levels or higher.
Horizon: EMM buyers: act in the next 60 days while steel weakness persists. Battery-grade buyers: window is now through Q3 — if LMFP adoption accelerates, expect a new price plateau by Q4 2026.
Trigger: Watch SMM weekly EMM prices — a sustained move above $2,400/tonne signals steel demand recovery and ends the buying window. For battery-grade, monitor sulfuric acid prices and Chinese ore import volumes: both are the primary cost drivers.
