What Is Phosphorus Used for and How Large Is the Industry?
DEA’s research indicates that there are currently only two domestic producers of elemental phosphorus. The primary material derived from phosphate rock is white phosphorus. Other forms of phosphorus and other phosphorus chemicals are manufactured from white phosphorus. DEA obtained 1998 and 1999 sales data from both producers. Over a twoyear period, the two firms had only a few customers. Each customer appears to be a large industrial firm. The DEA reviewed independent data for 1997 indicating that approximately 250,000 metric tons of elemental phosphorus were consumed in the U.S. Most consumers are large entities, which primarily use elemental phosphorous in the manufacture of phosphorous chemicals not impacted by this proposed regulation. White phosphorus is primarily used to produce phosphoric acid and other phosphorus compounds including phosphorus trichloride and phosphorous pentasulfide and phosphorus pentoxide. Over 98% of the annual U.S. phosphorus demand is used in the product
