Calling "fluorspar prices" a single number is the first mistake. Acid-grade fluorspar (acidspar, CaF₂ ≥ 97%) and metallurgical-grade (metspar, 60–85% CaF₂) trade on different supply curves, against different customer industries, and at prices that can diverge by 40–60% per tonne of CaF₂. In April 2026, acidspar CIF US Gulf is in the $550–650/MT range and metspar 85%-effective CIF US Gulf is $350–420/MT (as of 2026-04-14, source: Fastmarkets IM Fluorspar assessments). The two indices have moved together when global supply tightens generally, but their separate demand drivers — fluorochemicals vs steel flux — pull them apart on most cycles.
Global Production: China-Heavy, Slowly Diversifying
Global fluorspar production is roughly 8–9 Mt/yr (USGS Mineral Commodity Summaries 2026), with China supplying ~60% of the total. Mexico, Mongolia, South Africa, and Vietnam are the next-largest producers; the long tail includes Iran, Spain, Kenya, and Afghanistan. Fluorspar is listed as a strategic raw material under the EU Critical Raw Materials Act (Regulation 2024/1252) and appears on the US Department of Energy 2023 Critical Materials Assessment — both reflecting the supply-concentration concern.
China's Ministry of Commerce has periodically restricted fluorspar exports through licensing requirements; the regime is less aggressive than the antimony controls under MOFCOM Announcement No. 33 but still creates intermittent supply tightness for non-Chinese buyers. The trend over the past five years has been a slow ramp of non-Chinese acidspar capacity — particularly in Mexico, Mongolia, and Afghanistan — but the structural China dependence is real.
Acidspar Demand: HF and Its Downstream Chains
Acid-grade fluorspar (CaF₂ ≥ 97%, SiO₂ ≤ 1%, CaCO₃ ≤ 1.5%) is the feedstock for hydrofluoric acid (HF), which feeds five downstream chains — refrigerants, fluoropolymers, lithium-ion battery electrolyte (LiPF₆), uranium hexafluoride for nuclear fuel enrichment, and aluminium-smelting cryolite. The stream-by-stream demand breakdown — tonnage, timeline, and which chain concentrates the growth through 2030 — is the subject of the five emerging fluorspar demand streams; the market-relevant takeaway here is the price signal that demand creates.
Premium acidspar grades (97.5%+ CaF₂ with As < 5 ppm and P < 100 ppm) trade at $80–300/t over the standard 97% benchmark, driven by battery-electrolyte and semiconductor-grade demand. The premium is widening on tight battery-grade specifications.
Metspar Demand: Steelmaking Flux, Cement Mineraliser
Metallurgical-grade fluorspar is consumed by basic-oxygen-furnace (BOF) and electric-arc-furnace (EAF) steelmakers as a slag flux — it lowers slag viscosity and improves desulphurisation. Steelmakers value metspar by the "effective CaF₂" calculation: effective = CaF₂ − 2.5 × SiO₂. Common contract grades are 75% effective, 80% effective, and 85% effective. With global crude steel output at ~1.9 Gt/yr (worldsteel statistical bulletin), metspar demand is large and stable but barely growing — 1–2% annually, tracking steel demand.
Cement-grade fluorspar (CaF₂ 35–60%) acts as a clinker mineraliser, reducing the kiln calcination temperature by 50–100°C. This application is contract-priced (not indexed), small in absolute volume, and concentrated in cement plants that have engineered their kiln chemistry to use it.
Where Afghan and Pakistani Fluorspar Fit
Bare Syndicate's acid-grade fluorspar operation is in Kandahar, Afghanistan, producing CaF₂ ≥ 97% via heavy-media separation and froth flotation, with the As/P/SiO₂ profile suitable for HF acid plants and battery-electrolyte buyers (≥ 97.5% / As < 5 ppm and ≥ 98%+ / P < 100 ppm grades available). The Kandahar deposit has reserves disclosed at up to 8.8 Mt and operates at ~200 TPD. Pakistan-side metspar and ceramic-grade comes from partner operations.
Price Outlook for H2 2026
Holding the variables constant — Kigali Amendment phase-down on schedule, EV battery production scaling, no major Chinese export-licence tightening — H2 2026 base case:
- Standard acidspar 97% CaF₂ CIF US Gulf: $540–620/t (range as of 2026-04-14, source: Fastmarkets IM Acidspar Index).
- Premium acidspar 97.5%+ CaF₂ (battery-grade): $620–800/t depending on As / P spec.
- Metspar 85% effective CIF US Gulf: $340–410/t (Fastmarkets IM Metspar Index).
- Cement-grade: Contract-priced, indicative $200–260/t FOB origin.
Upside risk on acidspar: tighter Chinese export licensing, accelerated EV battery production, or a meaningful PVDF capacity expansion. Downside risk: EV demand softening in 2027, or accelerated non-Chinese acidspar capacity coming online.
Where the Fluorspar Read Goes Wrong
- Quoting a single "fluorspar price." Acidspar and metspar diverge by 40–60% per tonne and rarely move in lockstep.
- Saying "fluorspar is in the battery." Acidspar is upstream feedstock; the cell contains LiPF₆ salt and PVDF binder, both fluorine-derived downstream products. The supply-chain link is real but the marketing claim conflates feedstock and finished good.
- Saying metspar is a substitute for acidspar at the HF plant. It cannot be. SiO₂ contamination in metspar poisons HF production catalysts; the two products are not interchangeable at any price.
- Stating the Kigali Amendment "bans fluorine refrigerants." It phases down high-GWP HFCs; HFO replacements still contain fluorine. Total HF demand is roughly stable, not collapsing — the marketing claim that "refrigerant demand for HF is dying" is wrong and has misled procurement planning at more than one operator.
- Assuming Mexican or Mongolian capacity scales fast. New mine permits, beneficiation plant construction, and assay-qualification with HF buyers run 3–5 years; non-Chinese acidspar capacity additions are real but slow.
- Omitting the As / P spec when discussing battery-grade acidspar. CaF₂ percentage alone doesn't qualify a cargo for battery-electrolyte HF; arsenic and phosphorus are the differentiating impurities.
Procurement Posture for Fluorspar Buyers
For HF plant buyers, anchor contracts to the Fastmarkets IM Acidspar CIF US Gulf or FOB China index with a specific pricing window and a cargo-loading-date reference. Specify CaF₂, SiO₂, CaCO₃, S, As, and P limits explicitly — not "97% min" alone. For metspar buyers, the effective-CaF₂ formula goes into the LOI (effective = CaF₂ − 2.5 × SiO₂), with the dollar-per-effective-unit pricing mechanism set out at contract execution.
Next step: Request a delivered-cost indication for acidspar (97%, 97.5%, or 98%+ grade) from Bare Syndicate's Kandahar operation, or browse the non-acid-grade portfolio for metspar and cement-grade requirements.
