  1175Sulfur and Pyrites 
By Roland W. Merwin' 
 There were significant improvements in conditions in the sulfur industry
over those of 1971, with production, shipments, and apparent domestic consumption
reaching ailtime highs. This was a result of an upsurge in sulfur demand
for fertilizer manufacturing and an improvement in export demand. However,
the price position remained weak at the lowest level in more than 20 years.
This was a result of a continuing worldwide oversupply situation. There -were
indications at yearend that there might be a moderate improvement in domestic
prices in 1973. 
 Production of Frasch sulfur increased suibstantially over that of the previous
year, and there was an even larger increase in the production of recovered
elemental sulfur. There was only a small in-crease in the production of sulfur
in other forms. Shipments of sulfur in all -forms by domestic producers increased
because of increases in domestic consumption and export de 
-mands and a decline in imports. Shipments exceeded production, with the
deficit being met -by withdrawals from Frasch producers' 
stocks. The total value of shipments of sulfur in all forms increased from
$176.2 million in 1971 to $194.3 million in 1972. However, the average net
shipment value f.o.-b. mine or plant for Frasch and recovered elemental sulfur,
which accounted for 91% of the total shipments of sulfur in all ' forms in
1972, declined from $17.47 per long ton in 1971 to $17.04 per long ton in
1972. 
 -The United States improved its position as a net exporter of sulfur in
all forms. Exports of sulfur were substantially greater 
-than those in 1971 in the face of strong competition and low price levels.
There was a decrease in imports of sulfur in all forms. Imports from Canada
decreased moderately below those of 1971, mainly -because of the phasing
out of pyrites imports. Imports from Mexico decreased sharply because of
the imposition of duties under -the provisions of the Antidumping Act.
