Following price increases for US soda ash & exports to Asia in late 2007, two of the USA's four soda ash leaders based in Wyoming announced further increases . General Chemical Ind Prod Inc (GCIP) & its soda ash producer General Chemical (Soda Ash) Partners increased off-list prices for all bulk & packaged soda ash shipments by $50.00/ton effective immediately. List prices for all bulk & packaged soda ash shipments have been increased by $75/ton. The increase applies to all grades of soda ash from all GCIP plant, terminal & warehouse shipping locations. The new list prices, per ton FOB Green River, Wy, are: Bulk Dense Soda $260; Bulk Natural Light $265; Bulk Natural Light-HA $290; Bulk Dense Ash-Food Grade $375. The soda ash price increase by GCIP appears to be unprecedented, clearly outstripping the previous twice annual price rise of around $15/ton.
