Aluminium Trihydrate Price and Production Outlook
Global aluminium trihydrate (ATH, Al(OH)₃) production in 2025 is estimated at 2.98 to 3 million tonnes, reflecting its position as one of the most widely used inorganic fillers and flame retardants globally. Supply growth is closely tied to alumina refining activity, as aluminium trihydrate is both an intermediate and a derivative of the Bayer process.
Market conditions balance large-scale, cost-optimised production with application-driven differentiation in particle size, purity and surface treatment. The global picture shows steady capacity growth aligned with construction activity, wire and cable demand, plastics compounding and stricter fire safety standards.
Production leadership remains concentrated in China, Australia, Middle East, Brazil and India, supported by integrated bauxite mining and alumina refining capacity. Europe and North America rely on a mix of domestic specialty production and imports for high-purity grades.
Buyers prioritise consistent quality, particle morphology control, long-term supply security and predictable pricing.
Key Questions Answered
- How tightly is ATH supply linked to alumina refining cycles?
- How do energy and bauxite costs affect production economics?
- How fragmented is specialtygrade capacity versus commodity output?
