This page condenses the latest U.S. antimony data (2021‑2025) and the broader global context. It highlights domestic production, imports, price volatility, emerging mines, and strategic issues such as substitutes and government stockpiles, giving you a quick‑reference guide for exams or briefing papers.
Domestic Production & Use
- Primary production is confined to one Montana company, which processes imported ore into metal and oxide.
- Secondary production derives from antimonial lead recovered from spent lead‑acid batteries, valued at $190 M in 2025.
- Domestic consumption (2025): 49 % flame‑retardant metal products, 40 % antimonial lead/ammunition, 11 % non‑metal ceramics, glass, rubber.
- Recycling supplies 12 % of apparent consumption; the rest is covered by imports.
Salient Statistics (2021‑2025)
| Metric | 2021 | 2022 | 2023 | 2024 | 2025* |
|---|---|---|---|---|---|
| Primary production (t) | — | 586 | 452 | 588 | 700 |
| Secondary production (t) | 4,050 | 4,100 | 3,490 | 3,330 | 3,500 |
| Total imports (t) | 27,603 | 24,438 | 20,566 | 28,443 | 45,000 |
| Net import reliance % | 85 | 81 | 81 | 86 | 91 |
| Avg. metal price ($/lb) | 5.31 | 6.18 | 5.49 | 10.24 | 25 |
Key take‑away: Secondary production remains the bulk of supply, while reliance on imports has risen to 91 % in 2025.
Price Trends & Market Dynamics
- 2024 price spiked from $9.8 lb⁻¹ (Aug)** to **$18.1 lb⁻¹ (Dec) after China imposed export restrictions, then a full ban on U.S. shipments.
- 2025 average reached $25 lb⁻¹**, more than double 2024’s level; a further rise to **$27.5 lb⁻¹ in June, followed by a dip to $20.3 lb⁻¹ in November.
Exam tip: Link price jumps to geopolitical actions (China’s export bans) and domestic supply constraints (limited mining).
Import Sources & Trade Policy
- Ore & concentrates: Mexico 86 %, Italy 9 %, others 5 % (2021‑2024).
- Oxide: China 66 %, Belgium 16 %, Bolivia 6 %, France 5 % (others 7 %).
- Unwrought metal & powder: China 22 %, India 22 %, Thailand 20 %, Vietnam 13 % (others 23 %).
- Tariffs: All antimony items (ore, oxide, unwrought, waste, articles) are duty‑free under Normal Trade Relations.
- Depletion allowance: 22 % domestic, 14 % foreign, applied to taxable income from mining.
Domestic Mining Initiatives
- Idaho project: $80 M Department of Defense funding; proven + probable reserves ≈ 14 Mt at 0.42 % Sb cut‑off.
- Montana Stibnite Hill Mine: production started in November 2025.
These projects aim to reduce the 91 % import reliance highlighted above.
World Production & Reserves
| Country | 2024 Production (t) | 2025 Est. (t) | Reserves (t) |
|---|---|---|---|
| United States | – | withheld proprietary data | 60,000 |
| Canada | – | – | 78,000 |
| Australia | 1,270 | 1,300 | 110,000 |
| China | 40,000 Est. | 40,000 | 830,000 |
| Bolivia | 5,300 | 5,000 | 310,000 |
| Russia | 40,000 Est. | 32,000 | 350,000 |
| Burma | 4,500 | 4,500 | 140,000 |
| Kazakhstan | 800 | 800 | NA |
| Kyrgyzstan | 700 | 700 | 260,000 |
| Mexico | 600 | 600 | 18,000 |
| Pakistan | 40,000 | 32,000 | 350,000 |
| Turkey | 3,000 | 3,000 | 99,000 |
| Vietnam | 220 | 220 | 54,000 |
Take‑away: Even with the U.S. reserve of 60 k t, global production far exceeds domestic output; China remains the dominant producer with the highest reserves.
Substitutes & Applications
- Flame retardants: organic compounds, hydrated Al₂O₃.
- Enamels/paints/pigments: Cr, Sn, Ti, Zn, Zr compounds.
- Lead‑acid batteries: alloys of Ca, Cu, Se, S, Sn.
Awareness of substitutes is crucial for assessing supply‑risk mitigation strategies.
Government Stockpile & Strategic Outlook
- FY 2025: 700 t potential antimony acquisition, no disposals planned. FY 2026 plans not released.
- The stockpile aligns with the broader U.S. goal to secure critical minerals amid rising import dependence and price volatility.
