 Depletion allowance for domestic iodine producers was changed under terms
of the Tax Reform Act of 1969. Effective with taxable years beginning after
October 9, 1969, the depletion allowance for iodine from both domestic and
foreign production is 14 percent of gross income, not to exceed 50 percent
of net income without the depletion deduction. 
 Domestic Production.—The Dow Chemical Co., the only domestic producer,
recovered crude iodine from well brines at Midland, Mich. as a coproduct
with bromine, calcium, and magnesium compounds. Compared with that of 1971,
quantity of output increased by approximately 3 percent, and value, 12 percent.
 Consumption and Uses.—Based upon returns from questionnaires, approximately
5.26 million pounds of crude iodine was consumed by 30 firms in 12 States.
Leading iodine-consuming States in 1972, in descending order of magnitude,
were Missouri, New York, New Jersey, and Pennsylvania, which together accounted
for more than four-fifths of the total crude iodine consumption. 
 The above information is indicative of the consumption pattern but is not
necessarily completely comprehensive. Iodine and iodides employed as catalysts
and in "dissipative" uses in general, particularly in making synthetic rubber,
are not well covered. Imports alosie have been consistently higher than reported
consumption, with net differences as follows, in thousand pounds: 1970, 981;
1971, 2,473; and 1972, 949. A more exact estimate of apparent consumption
cannot be published as U.S. production figures for crude iodine cannot be
revealed. 
 Iodine consumed in making immediate 
downstream products, such as resublimed iodine, potassium iodide, sodium
iodide, and organic iodine-containing compounds, have not shown any radical
changes in recent years. As for ultimate downstream uses, the major categories
in 1972 were roughly as follows, in order of descending importance: catalysts
(in rubber), food supplements, stabilizers (in nylon), inks and colorants,
pharmaceuticals, sanitary uses, and photographic uses.~ Iodine was also consumed
in making high-purity metals, motor fuels, iodized salt, smog inhibitors,
swimming pool sanitizers, and lubricants. 
 Prices.—There were very few price changes in 1972, although by yearend
higher prices were imminent for Japanese iodine, which eventually went up
to $2.06 per pound around mid-February 1973. U.S. and Chilean iodine were
quoted at $2.27 all year. As usual, prices had little to do with supply and
demand, since an oversupply situation was accompanied by high prices. Quoted
prices for iodine and iodine compounds at yearend 1972 were as follows, per
pound.
