Cost Fa.ctors, The dehvered costs of the phosphate rock and sulfuric acid raw materials often account for more than 90% of the cost of producing NSP, thus the production cost varies considerably with plant location. Because the rock is richer in P2O5 than is the low analysis NSP product, NSP need not be produced near the phosphate mine. However, deUvery of sulfuric acid and shipment of product to market are important cost factors. Most United States NSP plants have been located east of the Mississippi river, with concentration in the southeastern and extreme southern parts of the country where the largest use of the product has occurred. Production and use of the product also has been high in California. 

Commercially pure (< 99.997%) helium is shipped directiy from helium-purification plants located near the natural-gas supply to bulk users and secondary distribution points throughout the world. Commercially pure argon is produced at many large air-separation plants and is transported to bulk users up to several hundred kilometers away by tmck, by railcar, and occasionally by dedicated gas pipeline (see Pipelines). Normally, only cmde grades of neon, krypton, and xenon are produced at air-separation plants. These are shipped to a central purification faciUty from which the pure materials, as well as smaller quantities and special grades of helium and argon, are then distributed. Radon is not distributed commercially. 

The 1990 price of anhydrous HCl was about 330/t the 1993 price of 20° Bh (31.4% HCl) was about 73/t (77). Prices depend on plant location, transportation burden, and on-site demand. These factors all influence the selling price significantly, sometimes carrying zero or negative value. 

Iodine plant locations in the United States and Japan are dictated primarily by the availabiHty of natural brines or bitterns containing adequate amounts of iodine. In 1992, the United States had three iodine-producing companies Woodward Iodine Corp., North American Brine Resources, and loChem. In Japan there are five iodine-producing companies, with over 30 plants Ise, Godo, Nippo, Nitten, and Kanto. AH these companies deHver iodine as flaked material except Ise, which also produces pfiUed iodine.

The primary siting factors which influence the selection of a plant location are as follows environmental considerations, labor avadabihty and productivity, raw material avadabihty, proximity to market, property cost, accessibdity to transportation, tax iacentives, electric power avadabdity and cost, and living conditions.
