Ammonium Sulfate


Ammonium Sulfate is non hazardous, non flammable fertilizer that is produced primarily as a byproduct of Caprolactam production. Caprolactam is the base stock used to produce nylon.

CIS packages and resells 20,000 tons of AdvanSix (Honeywell) ammonium sulfate (AMS) annually to the industrial and agricultural markets. Its primary industrial uses include pH control of solutions and cultures, as a fire retardant in cellulose and fiberglass insulation production, for rinsing during leather tanning, and as a binding material in wallboard. Primary agricultural uses are as a fertilizer and as an herbicide adjuvant (increases the effectiveness of weed controls).

Some of the better known AS customers have included GreenFiber, Benolec LTEE, Guardian Fiberglass, Bristol-Myers, Ashland Chemicals, Tannin Corp., and UNIVAR.

Since 1998 Commonwealth has packaged, sold, and shipped over 250,000 tons of AdvanSix (Honeywell) ammonium sulfate…without missing a shipment.
