Major chemicals producers AdvanSix raised its ammonium sulfate (amsul) prices for the fourth quarter on tight amsul supply across the US.
The company increased its prices, effective today, by $10-15/st from previous levels.
Granular amsul from AdvanSix's Hopewell, Virginia, plant increased by $10/st to $330/st fob.
Amsul along upper Mississippi River warehouses rose to $360/st fob while Ohio River and the Granite City, Illinois, warehouse price increased to $355/st fob.
Inland warehouses and rail quotes will maintain traditional premiums over river locations, the company said.
