This study of nonfertilizer phosphate manufacturing industry study, SIC 2819 and 2874, specifically involved three segments--4 defluorinated phosphate rock (DFP) plants, 11 defluorinated wet phosphoric acid plants and 1 sodium tripolyphosphate (STPP) plant. Most of the plants are reasonably profitable. Pricing of these products is complex in that their demand is derived, i.e. feed phosphates, liquid fertilizers, soaps and detergents. Feed phosphates and liquid fertilizer markets together are expected to grow at 8 to 12 percent per annum. STPP use is declining. Because of the amount of in-place pollution control technology, direct pass-on of control costs is not expected. The 4 DFP plants currently meet control requirements and should not be impacted. Three defluorinated acid plants may close due to pollution control regulations although one of these may close under baseline conditions. The STPP plant may close in face of impending pollution control guidelines.
