US Aluminium Trihydrate (ATH) prices are expected to decline in June 2026, with ChemAnalyst projecting a –2.1% move as alumina and caustic soda markets ease and downstream demand softens. Construction fillers, cable compounds, and flame retardant applications are entering a seasonal slowdown, while hurricane season caution is expected to further suppress procurement. Stabilizing bauxite costs and improved logistics reduce cost push pressure, allowing CFR Houston offers to soften. Precautionary buying ahead of tariff actions may provide limited support, but not enough to reverse the broader downward trend. May, by contrast, saw a 0.87% increase in ATH prices as buyers secured volumes early and logistics frictions tightened landed supply. Rising bauxite costs, firm alumina sentiment, and higher Santos–Houston freight supported offers, while steady construction fillers and plastics demand provided baseline consumption. However, ceramics and paper sectors remained weak, and overall demand was uneven.
