IODINE77Events, Trends, <strong>and</strong> Issues: Dem<strong>and</strong> for iodine has been driven in recent years by consumption for liquid crystaldisplays (LCD) <strong>and</strong> x-ray contrast media. With increased dem<strong>and</strong> in these two sectors <strong>and</strong> global iodine productionremaining constant, an imbalance between supply <strong>and</strong> dem<strong>and</strong> was created <strong>and</strong> resulted in iodine prices increasingby 19% from 2008 to 2009. As consumption of iodine in biocides, LCDs, <strong>and</strong> nylon declined owing to the globaleconomic downturn, prices remained relatively firm. The prices in 2010 were estimated to decrease slightly fromthose of 2009, but were projected to be more than 10% greater than those of 2008. With an economic recoveryexpected, dem<strong>and</strong> for iodine used in biocides, iodine salts, LCDs, synthetic fabric treatments, <strong>and</strong> x-ray contrastmedia was expected to increase at a rate of between 3.5% <strong>and</strong> 4% per year during the next decade.As in previous years, Chile was the world’s leading producer of iodine, followed by Japan <strong>and</strong> the United States. Chileaccounted for more than 50% of world production, having two of the leading iodine producers in the world. The largestChilean producer reported a 20% decrease in sales from 2008 to 2009, which was attributed to the global economicdownturn. In response to the downturn, the company announced the suspension of operations at one of its miningfacilities. The third largest Chilean producer initiated a new project at Algorta, Chile, which was expected to replace itscurrent operation at Lagunas, Chile.Several governmental programs were expected to affect future iodine dem<strong>and</strong>. The European Union prohibited its 27member countries from using or selling iodine for the purpose of disinfecting drinking water. China’s Ministry of Healthannounced the reduction of iodine content in salt owing to fears that iodized salt is causing a rise in thyroid disease.The U.S. <strong>Environmental</strong> Protection Agency approved the restricted use of the soil fumigant iodomethane (methyliodide) as an alternative to ozone-depleting methyl bromide. Australia <strong>and</strong> Belgium required bread manufacturers touse iodized salt with the intent of limiting iodine deficiency in their populations.World Mine Production <strong>and</strong> Reserves: The iodine reserves for Japan have been revised based on new informationfrom the country.Mine production Reserves 22009 2010 eUnited States W W 250,000Azerbaijan 300 300 170,000Chile 17,400 18,000 9,000,000China 580 590 4,000Indonesia 75 75 100,000Japan 9,600 9,800 5,000,000Russia 300 300 120,000Turkmenistan 270 270 170,000Uzbekistan 2 2NAWorld total (rounded)28,50029,000 15,000,000World Resources: In addition to the reserves shown above, seawater contains 0.05 parts per million iodine, orapproximately 34 million tons. Seaweeds of the Laminaria family are able to extract <strong>and</strong> accumulate up to 0.45%iodine on a dry basis. Although not as economical as the production of iodine as a byproduct of gas, nitrate, <strong>and</strong> oil,the seaweed industry represented a major source of iodine prior to 1959 <strong>and</strong> remains a large resource.Substitutes: There are no comparable substitutes for iodine in many of its principal applications, such as in animalfeed, catalytic, nutritional, pharmaceutical, <strong>and</strong> photographic uses. Bromine <strong>and</strong> chlorine could be substituted foriodine in biocide, colorant, <strong>and</strong> ink, although they are usually considered less desirable than iodine. Antibiotics can beused as a substitute for iodine biocides.e Estimated. NA Not available.

78IRON AND STEEL 1(Data in million metric tons of metal unless otherwise noted)Domestic Production <strong>and</strong> Use: The iron <strong>and</strong> steel industry <strong>and</strong> ferrous foundries produced goods in 2009 <strong>and</strong> 2010that were estimated to be valued at $74 billion <strong>and</strong> $139 billion, respectively. Pig iron was produced by 5 companiesoperating integrated steel mills in 15 locations. About 56 companies produce raw steel at about 114 minimills.Combined production capability was about 108 million tons. Indiana accounted for 24% of total raw steel production,followed by Ohio, 10%, Michigan, 7%, <strong>and</strong> Pennsylvania, 7%. The distribution of steel shipments was estimated tobe: warehouses <strong>and</strong> steel service centers, 25%; construction, 22%; transportation (predominantly automotive), 13%;cans <strong>and</strong> containers, 3%; <strong>and</strong> other, 37%.Salient Statistics—United States: 2006 2007 2008 2009 2010 ePig iron production 2 37.9 36.3 33.7 19.0 29Steel production: 98.2 98.1 91.9 59.4 90Basic oxygen furnaces, percent 42.9 41.8 42.6 38.2 39Electric arc furnaces, percent 57.1 58.2 57.4 61.8 61Continuously cast steel, percent 96.7 96.7 96.4 97 97Shipments:Steel mill products 99.3 96.5 89.3 56.4 76Steel castings e, 3 e 0.70.70.70.4 0.4Iron castings e, 3 e 7.47.47.44.0 4.0Imports of steel mill products 41.1 30.2 29.0 14.7 22Exports of steel mill products 8.8 10.1 12.2 8.4 11Apparent steel consumption 4 120 116 102 63 82Producer price index for steel mill products(1982=100) 5 174.1 182.9 220.6 165.2 200Steel mill product stocks at service centersyearend 6 15.0 9.3 7.8 5.6 6.7Total employment, average, numberBlast furnaces <strong>and</strong> steel mills 102,000 102,000 107,000e 109,000 110,000Iron <strong>and</strong> steel foundries e 95,000 95,000 86,000 86,000 86,000Net import reliance 7 as a percentage ofapparent consumption 17 16 13 11 7Recycling: See Iron <strong>and</strong> Steel Scrap <strong>and</strong> Iron <strong>and</strong> Steel Slag.Import Sources (2006–09): Canada, 19%; European Union, 15%; China, 13%; Mexico, 9%; <strong>and</strong> other, 44%.Tariff: Item Number Normal Trade Relations12-31-10Pig iron 7201.10.0000 Free.Carbon steel:Semifinished 7207.12.0050 Free.Hot-rolled, pickled 7208.27.0060 Free.Sheets, hot-rolled 7208.39.0030 Free.Cold-rolled 7209.18.2550 Free.Galvanized 7210.49.0090 Free.Bars, hot-rolled 7213.20.0000 Free.Structural shapes 7216.33.0090 Free.Stainless steel:Semifinished 7218.91.0015 Free.Do. 7218.99.0015 Free.Cold-rolled sheets 7219.33.0035 Free.Bars, cold-finished 7222.20.0075 Free.Pipe <strong>and</strong> tube 7304.41.3045 Free.Depletion Allowance: Not applicable.Government Stockpile: None.Prepared by Michael D.
