US Aluminium Trihydrate Prices Fall 1.79% as Comfortable Imports Pressure the Market

Aluminium Trihydrate CFR Houston prices declined 1.79% month-on-month in July 2026. The decline occurred despite rising production costs, as caustic soda prices increased by 2.45% during the month. Higher caustic soda costs raised the conversion expenses associated with Aluminium Trihydrate production and provided some support to supplier pricing. However, this cost pressure was outweighed by comfortable import availability and subdued downstream demand.Brazilian primary-alumina availability remained sufficient to support export flows into the U.S. Gulf Coast, while stable production operations prevented a significant tightening of Aluminium Trihydrate supply. On the demand side, construction-related consumption remained weak because of project delays, while wire-and-cable and electrical-equipment manufacturers mainly purchased against existing contracts. Engineered-polymer compounders also avoided aggressive spot procurement as inventories remained adequate. Consequently, suppliers were unable to fully pass higher feedstock costs through to buyers. Looking ahead, higher caustic soda costs could limit further price declines, but Aluminium Trihydrate values are likely to remain under pressure unless downstream demand strengthens, inventories tighten or Brazilian export availability is disrupted.
